THE NASDAQ STOCK MARKET

We are a holding company that operates The NASDAQ Stock Market LLC as our wholly-owned subsidiary. We became a holding company on August 1, 2006 when The NASDAQ Stock Market LLC commenced operations as a registered national securities exchange for Nasdaq-listed securities.

We, through our subsidiaries, are a leading provider of securities listing, trading, and information products and services. Our revenue sources are diverse and include revenues from transaction services, market data products and services, listing fees, insurance products, shareholder, directors and newswire services and financial products. The Nasdaq Stock Market is the largest electronic equity securities market in the United States, both in terms of number of listed companies and traded share volume. As of December 31, 2006, The Nasdaq Stock Market was home to approximately 3,193 listed companies with a combined market capitalization of over $4.1 trillion. We also operate, through the exchange subsidiary, The Nasdaq Market Center, which provides our market participants with the ability to access, process, display and integrate orders and quotes in The Nasdaq Stock Market and other national securities exchanges. Transactions involving 580.9 billion equity securities were executed on or reported to our systems in 2006, 59.9% higher than the 363.3 billion in 2005. We manage, operate and provide our products and services in two business segments, our Market Services segment and Issuer Services segment.

Philadelphia Stock Exchange

On November 6, 2007, we entered into a definitive agreement to acquire the Philadelphia Stock Exchange, the third largest options market in the United States and the nation’s oldest stock exchange. In addition to the options market, as part of the Philadelphia Stock Exchange acquisition, we will acquire a futures market operated by the Philadelphia Board of Trade, an equities business, and Stock Clearing Corporation of Philadelphia. Under the terms of the agreement, we will pay $652 million in cash consideration for the capital stock of the Philadelphia Stock Exchange. This transaction is expected to close in the first quarter of 2008. The Board of Directors of each company unanimously approved the transaction, which is subject to customary regulatory approvals.

Third Quarter Results

On October 24, 2007 we reported the following results for the third quarter of 2007. We reported third quarter 2007 net income of $365.0 million, or $2.41 per diluted share, an increase of $334.8 million from $30.2 million, or $0.22 per diluted share, in the third quarter of 2006, and an increase of $308.9 million from $56.1 million, or $0.39 per diluted share, in the second quarter of 2007.

S-1

Included in third quarter results were pre-tax gains of $431.4 million associated with the sale of our share capital of the London Stock Exchange, and $35.2 million related to gains on foreign currency option contracts. Also included in third quarter 2007 results were the following pre-tax charges:

•

$19.5 million associated with tax benefits shared with strategic investors,

•

$5.8 million related to the early extinguishment of debt, and

•

$1.1 million in workforce reduction expenses.

Revenues less liquidity rebates, brokerage, clearance and exchange fees (“net exchange revenues”) were $210.0 million in the third quarter of 2007, an increase of 22.7% from $171.2 million in the year-ago period, and up 5.7% from $198.7 million reported in the second quarter of 2007.

Recent Highlights

•

We expanded our leadership position as the largest single pool of liquidity in which to trade U.S. listed equities, matching 29.5% of all volume. We also achieved new market share highs in the trading of NYSE-listed equities, matching a record high 18.0% of volume during the quarter.

•

We announced the proposed acquisition of the Boston Stock Exchange (BSE), providing us with a second exchange license and, subject to SEC approval, utilization of the BSE Clearing Corporation.

•

We have agreed to acquire all the shares of OMX that Borse Dubai has acquired or will acquire through its August 9 announced offer for OMX. Our acquisition of OMX has received the support of the OMX Board and OMX’s largest shareholders.

•

We have agreed to acquire a 33 1/3% interest in Dubai International Financial Exchange, or DIFX, a subsidiary of Borse Dubai and an international stock exchange located in Dubai. Working with DIFX, we intend to develop DIFX into a regional center for capital formation.

•

We completed the sale of our share capital of the LSE for a $431.4 million pre-tax gain. Of the $1.8 billion in proceeds generated from the sale, $1.1 billion was used to retire outstanding debt obligations.

•

We launched the Portal Market, our electronic trading platform for 144A private placement securities. This market is designed to encourage capital formation by improving the efficiency and transparency of the private placement market.

•

We began operation of The Nasdaq ETF Market, designed specifically for exchange traded funds (ETFs) and Index Linked Notes (ILNs), further strengthening our leadership position in the U.S. ETF sector.

•

We launched the Select Market Maker Program, a certification program designed to recognize market makers who offer the highest levels of quoting and execution quality in Nasdaq-listed securities. Investors, Nasdaq-listed companies, funds, and prospective public companies benefit from the Select Market Maker Program through the ability to identify which firms continuously provide high-quality liquidity.

•

We launched Nasdaq Data Store, which provides online access to innovative data tools for institutional and individual investors. We were also recognized as the world’s premier stock exchange for data feeds for the second consecutive year in the annual Waters Rankings.

•

Increases in Nasdaq Market Center net exchange revenues from the prior year quarter were primarily due to increases in trade execution market share of NYSE- and AMEX-listed equities. Total NYSE-listed share volume reported to us increased from 27.5% in the third quarter of 2006 to 35.0% in the third quarter of 2007, while total AMEX-listed share volume reported to us increased from 47.7% to 52.4% for the same period. Increases when compared to the second quarter were primarily due to higher traded share volume matched in the Nasdaq Market Center, which increased 19.6% during the quarter. Included in execution and trade reporting revenues in the third quarter were $94.2 million in SEC Section 31 fees, compared with $73.1 million in the second quarter and $45.8 million in the third quarter of 2006. Corresponding cost of revenues reflecting the reimbursement of these fees to the SEC were included in brokerage, clearance and exchange fees.

•

Market Services Subscriptions revenues increased from the prior year quarter and second quarter of this year as growth in subscriber populations drove proprietary and non-proprietary revenues higher. Also contributing to the increase when compared to the prior year quarter was a decline in the amount of revenues shared through Nasdaq Revenue Sharing Programs, which resulted from changes to the plan structure. Somewhat offsetting these increases were higher revenues shared with UTP Plan participants due to higher non-proprietary revenues as well as a decline in our total UTP market share.

S-3

Issuer Services

During the third quarter Issuer Services revenues increased 22.4% to $73.2 million from the prior year quarter and increased 3.5% from prior quarter.

•

Increases in Corporate Client Group revenues from the prior year were driven primarily by revised annual renewal fees introduced earlier this year. Also contributing to the increase were higher revenues generated within our Corporate Client services, which were due to recent acquisitions and expanded customer use of services. Increases from the prior quarter were driven by fees generated from new listings as well as increasing customer utilization of our Corporate Client services.

•

Nasdaq Financial Products revenues increased from the prior year quarter and the second quarter due to an increase in fees associated with Nasdaq-licensed ETFs.

Total Operating Expenses

Total operating expenses increased 22.1% to $126.1 million from $103.3 million in the prior year quarter and increased 26.5% from $99.7 million in the prior quarter. Third quarter 2007 expenses increased from last year and prior quarter primarily due to a pre-tax charge of $19.5 million associated with tax benefits shared with strategic investors and a pre-tax charge of $5.8 million related to the early extinguishment of debt.

Earnings Per Share

Third quarter earnings per diluted share were $2.41 versus $0.22 per diluted share in the prior year quarter, and $0.39 in the second quarter of 2007. Our weighted average shares outstanding used to calculate diluted earnings per share were 152.3 million in the quarter versus 150.8 million in the year-ago quarter and 152.0 million in the second quarter of 2007.

¹⁾

Own work invested in assets during the period, which are carried as fixed assets, has been recognized in revenue under the heading “Own work capitalized.” This item refers only to capitalized personnel costs. Personnel costs were not reduced for the work pertaining to capitalized assets, instead the costs are met by reported revenue. Accordingly, revenue recognition of own work capitalized has no impact on results, but has a negative effect on the operating margin.

²⁾	For the period January-September 2007 Other revenue refers to earnings of SEK 101 m attributable to the sale of shares in ORC Software. For the period January-September 2006 the item refers to earnings of SEK 22 m attributable to the sale of shares in NOS ASA.

S-9

³⁾	Earnings per share are calculated on the basis of the weighted average number of shares during the period and is based on OMX AB shareholders’ share of earnings for the period.

⁴⁾	The income statement for discontinuing operations has been adjusted compared with interim reports in 2006 as a result of organizational changes where certain parts of the business area have been retained.

Management Commentary – third quarter income statement

OMX’s total revenue was SEK 1,002 m (817 m in the same period last year) during the third quarter of the year, up 23 percent compared with the year-earlier period. In the exchange operations, trading revenue increased mainly due to increased equities and derivatives trading. Information revenue also grew, partly due to the new Nordic product offering and increased demand for real-time terminals for market data. In the technology operations, the increase derives mainly from higher license, support and project revenue. The Iceland Stock Exchange was consolidated at December 1, 2006.

The Group’s total expenses amounted to SEK 694 m (592 m) during the quarter, up 17 percent compared with the year-earlier period. The increase is due mainly to higher resource requirements resulting from the expanded activities in the technology operations, an increased focus on products and services in information services, higher capacity requirements in the exchange operations, and the consolidation of the Iceland Stock Exchange. Compared with the second quarter of 2007, expenses declined by 8 percent mainly due to low levels of seasonal activity but also due to efficiency enhancements in the technology operations.

OMX’s operating income rose to SEK 320 m (238 m) in the third quarter. Excluding operations being discontinued, the operating income increased by 34 percent compared with the same period in 2006. Participations in earnings of associated companies amounted to SEK 12 m (13 m). The decrease is attributable to VPC AB no longer being included as an associated company, effective October 1, 2006. Earnings in the associated companies Orc Software and EDX London rose compared with the year-earlier period. Operating income before depreciation rose to SEK 386 m (296 m).

Financial items were negative in an amount of SEK 25 m (negative: 11 m). Compared with the preceding year, financial items were adversely affected by increased borrowing, rising market interest rates and higher costs for financial guarantees in conjunction with increased volumes in the clearing operations. Income after financial items rose to SEK 295 m (227 m) and income after tax rose to SEK 223 m (171 m). Earnings per share increased by 27 percent to SEK 1.82 (1.43).

The return on shareholders’ equity, based on rolling 12-month earnings, rose to 23 percent (17 percent). The net debt/equity ratio amounted to 23 percent (19 percent) at the end of the reporting period.

Management Commentary – nine months income statement

Total revenue amounted to SEK 3,192 m (2,585 m) in the period January – September. Consolidated net sales amounted to SEK 2,991 m (2,497 m). Own work capitalized amounted to SEK 100 m (66 m) during the period, primarily with respect to systems development.

The Group’s total expenses amounted to SEK 2,175 m (1,771 m) during the reporting period. The increase in costs was primarily due to increased consultancy and personnel expenses as a consequence of increased market activity, increased development of the next generation of trading systems and increased other external expenses in discontinuing operations.

The Group’s share in the earnings of associated companies amounted to SEK 36 m (42 m) and is attributable to EDX London, Orc Software, NLK and the Lithuanian securities depository, CSDL. In the year-earlier period, the earnings from associated companies also included a result of SEK 28 m from the then

S-10

associated company VPC AB. The underlying increase is mainly attributable to improved earnings for Orc Software and EDX London, and, during the second quarter, SEK 7 m from a dissolved provision at EDX London.

Net financial items for the Group amounted to an expense of SEK 59 m (expense: 44 m), including a dividend of SEK 17 m from Oslo Stock Exchange, a decline that is mainly due to increased borrowing, rising market interest rates and increased costs for financial guarantees in conjunction with increased volumes in the clearing operations. Tax expenses for the reporting period amounted to SEK 208 m (197 m), corresponding to a tax rate of 21 (24) percent. SEK 101 m from the sale of shares in Orc Software in the second quarter is not liable to tax. Currency effects have had a minimal impact on the Group’s operating revenue and operating income during the reporting period.

Through its clearing operations in the derivatives markets, Nordic Marketplaces is the formal counterparty in all derivatives positions traded via the exchanges. However, the exchanges do not utilize the derivatives for purpose of conducting their own trading, instead these derivatives are to be seen as a method of documenting the counterparty guarantees established in the clearing operations.

S-11

⁴⁾	Includes current trading accounts in the amount of SEK 838 m at September 30, 2007, SEK 582 m at September 30, 2006 and SEK 650 m at December 31, 2006, mainly arising in the UK operations for the sale of securities administration services, organized under operations being discontinued.

Management Commentary – balance sheet

Consolidated goodwill amounted to SEK 3,277 m (3,102 m) at period-end, including assets held for sale of SEK 30 m (31 m). Consolidated goodwill pertains primarily to the Nordic Marketplaces business area, and refers to strategic acquisitions of operations with a long history and stable and strong cash flow. During the period, investments in goodwill amounted to SEK 47 m, of which SEK 43 m was attributable to the acquisition of Findata AB.

Other intangible assets of SEK 1,503 m (1,083 m), including assets held for sale, consist mainly of capitalized development costs for system products that are amortized over a period of 3-10 years and valued on a current basis against prevailing market conditions, as well as intangible assets attributable to acquisitions. The increase in intangible assets is partly attributable to the acquisitions of Findata and EV (The Iceland Stock Exchange and CSD). Assessments to ascertain any potential impairment of intangible fixed assets are conducted continuously.

At period-end, the Group’s deferred tax assets amounted to SEK 47 m (153 m). Provisions were utilized in an amount of SEK 19 m (39 m) during the period.

The Group’s investments in other intangible assets during the period were SEK 360 m (176 m). A major part of the investments are within the technology operations, partly pertaining to a license from Cicada for technology pertaining to the development of a new system for information dissemination. In addition, assets of SEK 30 m on the acquisition of Findata AB have been identified as other intangible assets. Investments in tangible fixed assets amounted to SEK 49 m (34 m).

In the UK securities management operation, which is organized within discontinuing operations, OMX has the role of intermediary in securities transactions. During the period between transaction and settlement (usually one to five days), OMX has a receivable pertaining to the purchasing party and a liability pertaining to the selling party. These cannot be offset (see note 3 in the table above).

The market value of OMX’s remaining holding in the associated company Orc Software (3.8 million shares) at period-end was SEK 645 m (308 m), while the carrying amount was SEK 77 m (70 m).

DIVIDEND POLICY

You should not plan on receiving a dividend on your common stock. Our former credit facilities prohibited us from paying dividends and we expect our future credit facilities to also prohibit us from paying dividends. In the past, before our credit facilities had been in place, it was not our policy to declare or pay cash dividends on our common stock. We intend to retain any future earnings for meeting our obligations and funding our growth.

CERTAIN U.S. FEDERAL TAX CONSEQUENCES TO NON-U.S. HOLDERS

The following is a general discussion of certain U.S. federal income and estate tax consequences of the purchase, ownership and disposition of our common stock. This discussion applies only to a non-U.S. holder (as defined below) of our common stock. This discussion is based upon the provisions of the Internal Revenue Code of 1986, as amended, or the Code, the Treasury regulations promulgated thereunder and administrative and judicial interpretations thereof, all as of the date hereof, all of which are subject to change, possibly with retroactive effect. This discussion is limited to investors that hold our common stock as capital assets for U.S. federal income tax purposes. Furthermore, this discussion does not address all aspects of U.S. federal income and estate taxation that may be applicable to investors in light of their particular circumstances, or to investors subject to special treatment under U.S. federal income or estate tax law, such as financial institutions, insurance companies, tax-exempt organizations, entities that are treated as partnerships for U.S. federal tax purposes, dealers in securities or currencies, expatriates, persons deemed to sell our common stock under the constructive sale provisions of the Code and persons that hold our common stock as part of a straddle, hedge, conversion transaction or other integrated investment. Furthermore, this discussion does not address any U.S. federal gift tax consequences or any state, local or foreign tax consequences. Prospective investors should consult their tax advisors regarding the U.S. federal, state, local and foreign income, estate and other tax consequences of the purchase, ownership and disposition of our common stock.

For purposes of this summary, the term “non-U.S. holder” means a beneficial owner of our common stock that is not, for U.S. federal income and estate tax purposes, (i) a citizen or resident of the United States, (ii) a corporation or other entity subject to tax as a corporation for such purposes that is created or organized under the laws of the United States or any political subdivision thereof, (iii) a partnership (including any entity or arrangement treated as a partnership for such purposes), (iv) an estate the income of which is subject to U.S. federal income taxation regardless of its source, or (v) a trust (A) if a court within the United States is able to exercise primary supervision over its administration and one or more U.S. persons have the authority to control all of its substantial decisions or (B) that has made a valid election to be treated as a U.S. person for such purposes. If a partnership (including any entity or arrangement treated as a partnership for such purposes) owns our common stock, the tax treatment of a partner in the partnership will depend upon the status of the partner and the activities of the partnership. Partners in a partnership that owns our common stock should consult their tax advisors as to the particular U.S. federal income and estate tax consequences applicable to them.

Dividends

Dividends paid to a non-U.S. holder generally will be subject to withholding of U.S. federal income tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. Non-U.S. holders should consult their tax advisors regarding their entitlement to benefits under an applicable income tax treaty and the manner of claiming the benefits of such treaty. A non-U.S. holder that is eligible for a reduced rate of withholding tax under an income tax treaty may obtain a refund or credit of any excess amounts withheld by filing an appropriate claim for refund with the Internal Revenue Service.

Dividends that are effectively connected with a non-U.S. holder’s conduct of a trade or business in the United States and, if certain income tax treaties apply, that are attributable to a non-U.S. holder’s permanent establishment in the United States are not subject to the withholding tax described above but instead are subject to U.S. federal income tax on a net income basis at applicable graduated U.S. federal income tax rates. A non-U.S. holder must satisfy certain certification requirements for its effectively connected dividends to be exempt from the withholding tax described above. Dividends received by a foreign corporation that are effectively connected with its conduct of a trade or business in the United States may be subject to an additional branch profits tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.

S-17

Gain on Disposition of Common Stock

A non-U.S. holder generally will not be taxed on gain recognized on a disposition of our common stock unless:

•

the non-U.S. holder is an individual who holds our common stock as a capital asset, is present in the United States for 183 days or more during the taxable year of the disposition and meets certain other conditions;

•

the gain is effectively connected with the non-U.S. holder’s conduct of a trade or business in the United States and, if certain income tax treaties apply, is attributable to a non-U.S. Holder’s permanent establishment in the United States; or

•

we are or have been a “United States real property holding corporation” for U.S. federal income tax purposes at any time within the shorter of the five-year period ending on the date of disposition or the period that the non-U.S. holder held our common stock. We do not believe that we have been, currently are, or will become, a United States real property holding corporation.

•

If we were or were to become United States real property holding corporation at any time during the applicable period, however, any gain recognized on a disposition of our common stock by a non-U.S. Holder that did not own (directly, indirectly or constructively) more than 5% of our common stock during the applicable period would not be subject to U.S. federal income tax, provided that our common stock is “regularly traded on an established securities market” (within the meaning of Section 897(c)(3) of the Code). Individual non-U.S. holders who are subject to U.S. federal income tax because the holders were present in the United States for 183 days or more during the year of disposition are taxed on their gains (including gains from the sale of our common stock and net of applicable U.S. losses from sales or exchanges of other capital assets recognized during the year) at a flat rate of 30% or such lower rate as may be specified by an applicable income tax treaty. Other non-U.S. holders subject to U.S. federal income tax with respect to gain recognized on the disposition of our common stock generally will be taxed on any such gain on a net income basis at applicable graduated U.S. federal income tax rates and, in the case of foreign corporations, the branch profits tax discussed above also may apply.

Federal Estate Tax

Our common stock that is owned or treated as owned by an individual who is a non-U.S. holder at the time of death will be included in the individual’s gross estate for U.S. federal estate tax purposes, and, therefore, U.S. federal estate tax may be imposed with respect to the value of such stock, unless an applicable estate tax or other treaty provides otherwise.

Information Reporting and Backup Withholding

In general, backup withholding will apply to dividends on our common stock paid to a non-U.S. holder, unless the holder has provided the required certification that it is a non-U.S. holder and the payor does not have actual knowledge (or reason to know) that the holder is a U.S. person. Information generally will be reported to the Internal Revenue Service regarding the amount of dividends paid, the name and address of the recipient, and the amount, if any, of tax withheld. These information reporting requirements apply even if no tax was required to be withheld. A similar report is sent to the recipient of the dividend.

In general, backup withholding and information reporting will apply to the payment of proceeds from the disposition of our common stock by a non-U.S. holder through a U.S. office of a broker or through the non-U.S. office of a broker that is a U.S. person or has certain enumerated connections with the United States, unless the holder has provided the required certification that it is a non-U.S. holder and the payor does not have actual knowledge (or reason to know) that the holder is a U.S. person.

S-18

Backup withholding is not an additional tax. Any amounts that are withheld under the backup withholding rules from a payment to a non-U.S. holder will be refunded or credited against the holder’s U.S. federal income tax liability, if any, provided that certain required information is furnished to the Internal Revenue Service.

Non-U.S. holders should consult their tax advisors regarding the application of the information reporting and backup withholding rules to them.

S-19

PLAN OF DISTRIBUTION

General Plan of Distribution

We are registering 36,152,136 shares of our common stock on behalf of the Selling Stockholders who may sell shares of our common stock from time to time. The sales may be made on one or more exchanges or otherwise, at prices and at terms then prevailing or at prices related to the then current market price, or in negotiated transactions. The Selling Stockholders may effect such transactions by selling shares of common stock to or through broker-dealers. Shares of common stock may be sold by one or more of, or a combination of, the following:

•

purchases by broker-dealers, including block trades in which a broker-dealer will attempt to sell shares of common stock as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•

purchases by a broker-dealer as principal and resale by such broker-dealer for its account;

•

purchases through agents;

•

purchases through underwriters;

•

ordinary brokerage transactions and transactions in which the broker solicits purchasers;

•

directly to one or more purchasers;

•

privately negotiated transactions; and

•

any other method permitted pursuant to applicable law.

The Selling Stockholders may negotiate and pay broker-dealers or other persons commissions, discounts or concessions for their services. Broker-dealers or other persons engaged by the Selling Stockholders may allow other broker-dealers or other persons to participate in resales. However, any broker-dealers or such other persons involved in the sale or resale of shares of common stock may qualify as “underwriters” within the meaning of the Section 2(a)(11) of the Securities Act of 1933, as amended (the “Securities Act”). In addition, the broker-dealers’ or their affiliates’ commissions, discounts or concessions may qualify as underwriters’ compensation under the Securities Act.

In addition to selling their shares of common stock under this prospectus supplement, the Selling Stockholders may:

•

agree to indemnify any broker-dealer or agent against certain liabilities related to the selling of the common stock, including liabilities arising under the Securities Act;

•

transfer their shares of common stock in other ways not involving market makers or established trading markets, including directly by gift, distribution, or other transfer; or

•

sell their shares of common stock under Rule 144 of the Securities Act rather than under this prospectus, if the transaction meets the requirements of Rule 144.

The shares of common stock may be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states the shares of common stock may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Additional information related to the Selling Stockholders and the plan of distribution may be provided in one or more prospectus supplements.

S-20

Furthermore, the Selling Stockholders are not obligated to offer or sell the shares of common stock referred to in this prospectus supplement issuable upon conversion of the 3.75% Convertible Notes due 2012 or exercise of our Series A Warrants and Series B Warrants, and may choose to offer and sell the notes, the warrants, the common stock or any combination thereof. The Selling Stockholders have the right to request the registration of such other securities.

Nasdaq will bear all costs, expenses and fees in connection with the registration of shares of common stock. The Selling Stockholders will bear all commissions and discounts, if any, attributable to the sales of the shares of common stock and all of their out-of-pocket expenses for their counsel and accountants. Nasdaq has agreed to use its reasonable best efforts to keep the registration of the shares of common stock effective until the date when all of the shares of common stock have been sold, subject to certain exceptions.

Underwriting

We and certain of the Selling Stockholders expect to enter into a purchase agreement with the underwriter named in a subsequent prospectus supplement (the “underwriter”) with respect to the shares of common stock to be offered and sold in a future offering. Subject to certain conditions, the underwriter will agree to purchase all of the shares offered thereby.

The underwriter may receive from purchasers of the shares normal brokerage commissions in amounts agreed with such purchasers.

The underwriter may propose to offer the shares of common stock from time to time for sale in one or more transactions in The NASDAQ Global Select Market, in the over-the-counter market, through negotiated transactions or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices, subject to receipt and acceptance by it and subject to its right to reject any order in whole or in part. In connection with the sale of the shares of common stock offered thereby, the underwriter may be deemed to have received compensation in the form of underwriting discounts. The underwriter may effect such transactions by selling shares of common stock to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriter and / or purchasers of shares of common stock for whom they may act as agents or to whom they may sell as principal.

In connection with such an offering, the underwriter may purchase and sell shares of common stock in the open market. These transactions may include short sales and purchases to cover positions created by short sales. Short sales involve the sale by the underwriter of a greater number of shares than it would be required to purchase in such an offering. The underwriter will need to close out any short sale by purchasing shares in the open market. The underwriter is likely create a short position if it is concerned that there may be downward pressure on the price of the common stock in the open market after pricing that could adversely affect investors who purchase in such an offering.

Purchases to cover a short position, as well as other purchases by the underwriter for its own account, may have the effect of preventing or retarding a decline in the market price of the company’s stock, and may maintain or otherwise affect the market price of the common stock. As a result, the price of the common stock may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued at any time. These transactions may be effected on The NASDAQ Global Select Market, in the over-the-counter market or otherwise.

Our common stock is listed on the NASDAQ Global Select Market under the symbol “NDAQ.”

The underwriter may require us, our officers and directors and the Selling Stockholders, subject to certain exceptions, not to offer, sell, contract to sell, announce any intention to sell, pledge or otherwise dispose of, directly of indirectly, or file with the SEC a registration statement under the Securities Act relating to, any

S-21

common shares or securities convertible into or exchangeable or exercisable for any common shares without the underwriter’s prior written consent for 30 days or some other specified period of time after the date of such an offering.

The underwriter is likely to represent and agree that:

(c) in any other circumstances which do not require the publication by the Issuer of a prospectus pursuant to Article 3 of the Prospectus Directive.

The shares may not be offered or sold by means of any document other than to persons whose ordinary business is to buy or sell shares or debentures, whether as principal or agent, or in circumstances which do not constitute an offer to the public within the meaning of the Companies Ordinance (Cap. 32) of Hong Kong, and no

S-22

USE OF PROCEEDS

Unless otherwise set forth in a prospectus supplement, we intend to use the net proceeds of any offering of securities sold by us for general corporate purposes, which may include acquisitions, repayment of debt, capital expenditures and working capital. When a particular series of securities is offered, the prospectus supplement relating to that offering will set forth our intended use of the net proceeds received from the sale of those securities. The net proceeds may be invested temporarily in short-term marketable securities or applied to repay short-term debt until they are used for their stated purpose.

Unless otherwise set forth in a prospectus supplement, we will not receive any proceeds in the event that the securities are sold by a selling securityholder.

DESCRIPTION OF SECURITIES

This prospectus contains summary descriptions of the debt securities, common stock, preferred stock, and warrants that we may sell from time to time. These summary descriptions are not meant to be complete descriptions of each security. The particular terms of any security will be described in the related prospectus supplement.

DESCRIPTION OF DEBT SECURITIES

The debt securities will either be senior debt securities or subordinated debt securities. Senior debt securities will be issued under a senior indenture and subordinated debt securities will be issued under a subordinated indenture. Unless otherwise specified in the applicable prospectus supplement, the trustee under the indentures will be The Bank of New York. The forms of indentures are filed as exhibits to the registration statement of which this prospectus forms a part. We will include in a supplement to this prospectus the specific terms of each series of debt securities being offered, including the terms, if any, on which a series of debt securities may be convertible into or exchangeable for our common stock, preferred stock or other debt securities. The statements and descriptions in this prospectus or in any prospectus supplement regarding provisions of the indentures and debt securities are summaries thereof, do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of the indentures (and any amendments or supplements we may enter into from time to time which are permitted under each indenture) and the debt securities, including the definitions therein of certain terms.

Unless otherwise specified in a prospectus supplement, the debt securities will be direct unsecured obligations of The Nasdaq Stock Market, Inc. and will not be guaranteed by any of our subsidiaries. The senior debt securities will rank equally with any of our other senior and unsubordinated debt. The subordinated debt securities will be subordinate and junior in right of payment to any senior indebtedness. The indentures do not limit the aggregate principal amount of debt securities that we may issue and provide that we may issue debt securities from time to time in one or more series, in each case with the same or various maturities, at par or at a discount. Unless indicated in a prospectus supplement, we may issue additional debt securities of a particular series without the consent of the holders of the debt securities of such series outstanding at the time of the issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of debt securities under the applicable indenture.

DESCRIPTION OF COMMON STOCK

General

As of December 31, 2005, we are authorized to issue up to 300,000,000 shares of common stock. Mellon Investor Services is the transfer agent and registrar for our common stock. Shares of common stock are quoted on the Nasdaq National Market under the trading symbol “NDAQ.”

The holders of common stock are entitled to one vote per share on all matters to be voted upon by the stockholders except that any person, other than NASD or any other person as may be approved for such exemption by the board of directors prior to the time such person owns more than 5% of the then outstanding shares of common stock, who otherwise would be entitled to exercise voting rights in respect of more than 5% of the then outstanding shares of common stock will be unable to exercise voting rights in respect of any shares in excess of 5% of the then outstanding shares of common stock. At any meeting of our stockholders, a majority of the votes entitled to be cast (currently, the common stock, Series D Preferred Stock and 3.75% convertible subordinated notes due 2012) will constitute a quorum for such meeting. Additionally, in response to the SEC’s concern about a concentration of our ownership, our exchange registration application includes a rule that, effective upon exchange registration, prohibits any member of Nasdaq or a person associated with such member from beneficially owning more than 5% of the outstanding shares of common stock.

Under the certificate of incorporation, our board of directors may waive the application of the 5% voting limitation to persons other than brokers, dealers, their affiliates, and persons subject to statutory disqualification under Section 3(a)(39) of the Exchange Act. In the event that the board of directors approves an exemption from the 5% voting limitation (other than an exemption granted in connection with a strategic market alliance) and seeks the concurrence of the SEC with respect thereto, we have agreed to grant Hellman & Friedman and Silver Lake Partners, holders of our 3.75% convertible subordinated notes, a comparable exemption from such limitation and to use our best efforts to obtain SEC concurrence of such exemption. At our 2005 Annual Meeting of Stockholders, stockholders approved an amendment to the certificate of incorporation granting each of the holders of the convertible notes the right to vote with the holders of common stock and Series D Preferred Stock on matters submitted to a vote of stockholders, subject to the 5% voting limitation.

Holders of common stock are entitled to receive ratably such dividends, if any, as may be declared from time to time by the board of directors out of funds legally available for them. In the event of liquidation, dissolution, or winding-up of Nasdaq, the holders of common stock are entitled to share ratably in all assets remaining after payment of liabilities, subject to prior distribution rights of preferred stock, if any, then outstanding. The common stock has no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the common stock. All outstanding shares of common stock are fully paid and non-assessable, and the shares of common stock to be issued upon completion of this offering will be fully paid and non-assessable. We have not declared or paid cash dividends on our common stock. We currently do not intend to pay any cash dividends on our common stock. Rather, we currently plan to retain any future earnings for funding our growth. Future dividends, if any, will be determined by our board of directors.

This summary is not meant to be complete. You should refer to the applicable provision of our charter and by-laws and to Delaware corporate law for a complete statement of the terms and rights of our common stock.

DESCRIPTION OF PREFERRED STOCK

The board of directors may provide by resolution for the issuance of preferred stock, in one or more series, and to fix the powers, preferences, and rights, and the qualifications, limitations, and restrictions thereof, of this preferred stock, including dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund provisions, if any, and the number of shares constituting any series or the designation of such series. The issuance of preferred stock could have the effect of decreasing the market price of the common stock and could adversely affect the voting and other rights of the holders of common stock.

We will include in a prospectus supplement the terms relating to any series of preferred stock being offered. These terms will include some or all of the following:

the title of the series and the number of shares in the series;

the price at which the preferred stock will be offered;

the dividend rate or rates or method of calculating the rates, the dates on which the dividends will be payable, whether or not dividends will be cumulative or noncumulative and, if cumulative, the dates from which dividends on the preferred stock being offered will cumulate;

the voting rights, if any, of the holders of shares of the preferred stock being offered;

the provisions for a sinking fund, if any, and the provisions for redemption, if applicable, of the preferred stock being offered;

the liquidation preference per share;

the terms and conditions, if applicable, upon which the preferred stock being offered will be convertible into our common stock, including the conversion price, or the manner of calculating the conversion price, and the conversion period;

the terms and conditions, if applicable, upon which the preferred stock being offered will be exchangeable for debt securities, including the exchange price, or the manner of calculating the exchange price, and the exchange period;

any listing of the preferred stock being offered on any securities exchange;

whether interests in the shares of the series will be represented by depositary shares;

a discussion of any material U.S. federal income tax considerations applicable to the preferred stock being offered;

the relative ranking and preferences of the preferred stock being offered as to dividend rights and rights upon liquidation, dissolution, or the winding up of our affairs;

any limitations on the issuance of any class or series of preferred stock ranking senior or equal to the series of preferred stock being offered as to dividend rights and rights upon liquidation, dissolution or the winding up of our affairs; and

any additional rights, preferences, qualifications, limitations, and restrictions of the series.

Upon issuance, the shares of preferred stock will be fully paid and nonassessable, which means that its holders will have paid their purchase price in full and we may not require them to pay additional funds. Holders of preferred stock will not have any preemptive rights.

DESCRIPTION OF WARRANTS

We may issue warrants to purchase debt or equity securities. Each warrant will entitle the holder of warrants to purchase for cash the amount of debt or equity securities, at the exercise price stated or determinable in the prospectus supplement for the warrants. We may issue warrants independently or together with any offered securities. The warrants may be attached to or separate from those offered securities. We will issue the warrants under warrant agreements to be entered into between us and a bank or trust company, as warrant agent, all as described in the applicable prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.

The prospectus supplement relating to any warrants that we may offer will contain the specific terms of the warrants. These terms may include the following:

the title of the warrants;

the designation, amount and terms of the securities for which the warrants are exercisable;

the designation and terms of the other securities, if any, with which the warrants are to be issued and the number of warrants issued with each other security;

the price or prices at which the warrants will be issued;

the aggregate number of warrants;

any provisions for adjustment of the number or amount of securities receivable upon exercise of the warrants or the exercise price of the warrants;

the price or prices at which the securities purchasable upon exercise of the warrants may be purchased;

if applicable, the date on and after which the warrants and the securities purchasable upon exercise of the warrants will be separately transferable;

if applicable, a discussion of the material U.S. federal income tax considerations applicable to the exercise of the warrants;

the date on which the right to exercise the warrants will commence, and the date on which the right will expire;

the maximum or minimum number of warrants that may be exercised at any time;

information with respect to book-entry procedures, if any; and

any other terms of the warrants, including terms, procedures and limitations relating to the exchange and exercise of the warrants.

LEGAL MATTERS

In connection with particular offerings of the securities in the future, and unless otherwise indicated in the applicable prospectus supplement, the validity of those securities will be passed upon for The Nasdaq Stock Market, Inc. by Skadden, Arps, Slate, Meagher & Flom LLP, New York, New York.
