As of February 2, 2026, the meteoric rise of prediction markets has hit a significant roadblock not in Washington D.C., but in the state houses of Nevada and Connecticut. While 2025 was defined by Kalshi’s historic legal victory against the Commodity Futures Trading Commission (CFTC), 2026 has opened with a multi-front "guerrilla war" as state gaming authorities attempt to reclassify prediction markets as unlicensed gambling.
The core of the dispute rests on Kalshi’s aggressive expansion into sports event contracts—markets that allow users to hedge on the outcome of NFL games, the Super Bowl, and NBA matchups. With state regulators in Nevada and Connecticut issuing cease-and-desist orders, the legal battle is no longer a matter of administrative law, but a fundamental question of federal preemption. Traders are now pricing in a significant risk that Kalshi could be forced to geofence up to 15 states by the end of the year, a move that could jeopardize its status as the world’s volume leader in the prediction market space.
The Market: What's Being Predicted
The primary "market" currently under observation is the legal survival of Kalshi’s sports contracts in key jurisdictions. In January 2026 alone, Kalshi processed an estimated $9.1 billion in trading volume, with a staggering 91.1% of that activity tied directly to sports event contracts. For comparison, its main rival, Polymarket, saw approximately $7.5 billion in volume during the same period.
While Kalshi currently maintains a 28.1% share of the global prediction market volume, meta-markets on platforms like Manifold Markets have begun to reflect a shift in sentiment. Traders are currently giving Polymarket a 47% chance of finishing 2026 as the top platform by volume, while Kalshi’s odds have slipped to 34%. This inversion is driven almost entirely by the regulatory friction in Nevada and Connecticut.
The resolution of these state-level battles depends on two upcoming legal milestones:
- Connecticut District Court: A high-stakes hearing scheduled for February 12, 2026, where a judge will decide whether to grant a preliminary injunction against the Connecticut Department of Consumer Protection (DCP).
- The Ninth Circuit Court of Appeals: Oral arguments are set for April 2026 regarding the Nevada Gaming Control Board's (NGCB) attempt to shut down Kalshi operations in the state.
Why Traders Are Betting
Traders and legal analysts are divided on the "federal preemption" defense. Kalshi argues that because its contracts are regulated by the CFTC as financial derivatives under the Commodity Exchange Act (CEA), state gaming laws are preempted. However, the Nevada Gaming Control Board disagrees, citing NRS 463.0193, which defines any wager on a sporting event as gambling that requires a state license.
The market sentiment shifted significantly in late November 2025, when U.S. District Judge Andrew Gordon dissolved a preliminary injunction that had protected Kalshi in Nevada. Gordon’s ruling suggested that stripping states of their power to regulate gambling would "upset decades of federalism." This legal pivot has led "whale" traders to hedge their Kalshi positions by moving liquidity toward platforms like Polymarket or Robinhood (NASDAQ: HOOD), the latter of which also faces scrutiny but has a broader diversification of assets.
Furthermore, the Connecticut DCP, led by Commissioner Bryan T. Cafferelli, has introduced a "consumer protection" narrative, arguing that Kalshi lacks the age-verification rigors and responsible gaming safeguards required by state law. This has introduced a new variable: even if Kalshi wins on the "gambling" definition, it could still be hamstrung by state-level administrative hurdles.
Broader Context and Implications
This conflict represents the "final frontier" for prediction markets in the United States. If Kalshi loses these cases, it would create a fragmented "patchwork" regulatory environment. This would lead to what analysts call "phantom liquidity"—where price discovery occurs on a national level, but users in states like Nevada or Connecticut are geofenced out, leading to wider spreads and less efficient markets.
The implications for 2026 volume leadership are profound. Kalshi’s business model is uniquely exposed to sports, which act as the "on-ramp" for many retail traders. If the platform is forced to exit Nevada—the spiritual home of American sports betting—its competitive advantage over Polymarket and newer entrants like Crypto.com (which also received a Connecticut cease-and-desist) could evaporate.
Historically, prediction markets have thrived on being "information engines." However, the transition into sports has moved them into the crosshairs of powerful state gaming commissions that protect billions in tax revenue from traditional sportsbooks. The current legal battle is less about "what is a derivative" and more about "who gets to tax the trade."
What to Watch Next
The immediate focus for the market is the February 12 hearing in Connecticut. Judge Vernon Oliver’s decision on the preliminary injunction will serve as a bellwether. If he sides with the DCP and allows the cease-and-desist to stand, it is expected that 5–10 other states will follow suit with similar orders by the end of Q1 2026.
Beyond the courtroom, watch for Kalshi to potentially pivot its product mix. To mitigate the "unlicensed gambling" risk, the exchange may begin prioritizing "non-event" economic contracts or midterm election hedging markets to dilute the percentage of its volume coming from sports.
Finally, the Ninth Circuit's oral arguments in April will be the definitive moment for the industry. A ruling in favor of the Nevada Gaming Control Board would likely force the issue to the U.S. Supreme Court, creating years of uncertainty for the prediction market sector.
Bottom Line
Kalshi entered 2026 with the momentum of a dominant incumbent, but the "State-Level Pushback" has proven to be a more resilient foe than the federal CFTC. The argument that sports event contracts are unlicensed gambling is gaining traction among state judges who are wary of federal overreach into local police powers.
For prediction market participants, the current volatility in "platform dominance" markets is a reflection of this legal reality. While Kalshi still holds the volume crown today, its path to 2026 leadership is now narrow and heavily dependent on winning a series of high-stakes legal coin flips. If the Connecticut and Nevada dominos fall against the exchange, the "regulated US market" may look very different by this time next year.
The next two weeks will be among the most consequential in the history of the industry. As the February 12 deadline approaches, expect liquidity to be cautious and the "State-Level Risk" premium to remain high.
