The fight over who regulates prediction markets in the United States has escalated into one of the most consequential federal-vs-state legal battles in gambling history. The Commodity Futures Trading Commission claims exclusive jurisdiction over platforms like Kalshi and Polymarket. State gaming regulators in dozens of jurisdictions say those platforms are running unlicensed sports betting in violation of state law. Federal courts have largely sided with the CFTC so far, but the political and legal pressure from states is intensifying — and the outcome will shape American gambling regulation for the next decade.
The Core Jurisdictional Dispute
Prediction markets like Kalshi and Polymarket allow users to buy and sell contracts on the outcome of real-world events — political elections, weather events, sports games, financial benchmarks. Kalshi is registered with the CFTC as a Designated Contract Market, which the agency argues gives it the same regulatory status as a futures exchange like CME Group. Polymarket operates from outside the US but accepts US customers through a peer-to-peer mechanism, putting it in a gray zone the CFTC has begun litigating.
Quick answer: The CFTC claims exclusive federal jurisdiction over prediction markets like Kalshi under commodities law. State gaming regulators argue these platforms are unlicensed sports betting under state gambling statutes. Federal courts have so far sided with the CFTC. Texas, Minnesota, Massachusetts, and other states are pushing legislation and litigation to assert state authority. The outcome will reshape US gambling regulation.
How the States Are Pushing Back
More than two dozen state attorneys general and gaming regulators have taken action against prediction market operators in the past 12 months. Nevada and Washington issued cease-and-desist letters to Kalshi early in the dispute. Arizona joined later. Massachusetts went a step further, filing suit against Polymarket alleging unlicensed sports betting operations.
The most ambitious state action is in Minnesota, where legislators have advanced a bill that would explicitly ban prediction market platforms operating without a state gambling license. If signed into law, Minnesota would become the first state to outright prohibit Kalshi and Polymarket access. Texas is preparing similar legislation, with Governor's office support reportedly contingent on the language clearing constitutional concerns about CFTC pre-emption.
The CFTC Strikes Back
The CFTC has fought aggressively to defend its jurisdiction. The agency filed lawsuits against several states attempting to enforce state-level restrictions on Kalshi. A federal appeals court ruled in April 2025 that New Jersey regulators could not bar the use of Kalshi to place sports event contracts, citing CFTC pre-emption under the Commodity Exchange Act.
The CFTC argues that allowing 50 different state regulatory regimes to govern prediction markets would destroy the national futures market structure and create regulatory chaos. The agency has signaled that any state action restricting CFTC-registered exchanges will be met with federal litigation. This stance has emboldened Kalshi to expand aggressively into sports contracts including NBA, NFL, and college sports outcomes.
Congressional Pressure on Both Sides
Both Democrats and Republicans have weighed in, but with different concerns. A group of Senate Democrats led by Jeff Merkley has urged the CFTC to issue rules reining in prediction markets, citing concerns about market manipulation, election integrity, and a "rapid erosion of integrity" within the platforms. Republican lawmakers have generally supported the prediction market industry but want clearer guardrails around event contract design.
House and Senate Agriculture Committee leaders have signaled possible legislative reform of the Commodity Exchange Act to clarify federal-vs-state authority over event contracts. Any such reform would take 12-24 months minimum, leaving the current legal uncertainty in place through most of 2026.
Sports Betting Industry Reaction
Traditional sportsbook operators are caught between two impulses. On one hand, prediction markets compete directly with their core sports betting products without the same state-by-state licensing costs or tax burdens. On the other hand, prediction markets offer a federal regulatory model that could be cheaper and more efficient than the current state-by-state patchwork.
DraftKings has chosen direct engagement, launching its own prediction product integrated into the main sportsbook app. The company reported in Q1 2026 that customer acquisition costs for prediction users were 80% lower than for sportsbook users, suggesting the format has structural advantages. FanDuel has been more cautious, with CEO succession at parent Flutter leaving the prediction market strategy in flux. DraftKings review and FanDuel review cover each operator's approach.
What Could Resolve the Dispute
Three paths could resolve the federal-state standoff. First, a Supreme Court decision on CFTC pre-emption — likely if Texas or another state pursues litigation to the highest level. Second, congressional reform of the Commodity Exchange Act explicitly addressing event contracts and state authority. Third, a settlement between the CFTC and major state gaming regulators establishing a hybrid framework where states retain authority over certain contract types (such as in-state sporting events) while CFTC retains authority over national and political contracts.
None of these paths is imminent. The Supreme Court has not signaled interest in taking up the issue. Congressional reform is unlikely before the 2026 midterm elections. A negotiated settlement requires goodwill that does not currently exist between federal and state regulators.
What This Means for US Bettors
For US sports bettors, the uncertainty creates both opportunity and risk. Prediction markets currently offer better odds on certain contracts than traditional sportsbooks because of the lower regulatory cost structure. But the platforms could face sudden access restrictions if state-level enforcement succeeds, leaving users with stranded funds or unsettled positions.
The practical advice: if you use prediction markets, treat them as a supplemental product rather than a primary one. Keep balances modest, withdraw winnings regularly, and maintain accounts at fully regulated sportsbooks for core betting activity. See our US sports betting guide for state-by-state licensed options.
The Election Year Wildcard
2026 is a midterm election year, and prediction markets are once again attracting scrutiny for their election contracts. The CFTC has historically restricted election contracts above certain dollar thresholds, but Kalshi has pushed the boundaries with congressional race contracts and event contracts on senate composition. State attorneys general have raised election integrity concerns separate from the broader prediction market debate.
Expect the election contract dispute to intensify as the midterms approach. The political optics of allowing or restricting election betting will shape both regulator behavior and legislative pressure. Industry observers expect at least one major CFTC enforcement action or court ruling on election contracts before November 2026.
Implications for State-Licensed Sportsbooks
If the CFTC ultimately prevails, state-licensed sportsbooks face a structural cost disadvantage. State gaming taxes range from 6.75% in Nevada to over 50% in some new markets. Prediction markets pay no equivalent state tax. To compete, state-licensed operators would need either lower state tax rates or their own federally regulated product line — which would require regulatory reform unlikely in the next 24 months.
If states ultimately prevail, prediction markets face a 50-state licensing regime that would dramatically raise their operating costs and likely limit availability across the country. Smaller prediction market operators would not survive that transition. Kalshi and Polymarket would continue but on materially different terms.
Frequently Asked Questions
Is it legal to use Kalshi or Polymarket in my state?
Kalshi operates legally under CFTC registration in most US states, though some states (notably Nevada and Washington) have issued cease-and-desist letters. Polymarket's US accessibility is more legally ambiguous. Check your state's current rules before depositing.
Will the Supreme Court hear the CFTC pre-emption case?
Possibly, but no case has yet reached the Supreme Court. The most likely path is a Fifth Circuit decision out of Texas litigation that the Supreme Court could choose to review on certiorari.
How does this affect traditional sports betting?
Indirectly but significantly. Prediction markets are growing market share faster than traditional sportsbooks and may force regulatory changes to state betting markets. Operators are adjusting their best sportsbook promos and product offerings in response.
What is the difference between Kalshi and Polymarket?
Kalshi is US-based, CFTC-regulated, and operates with a traditional exchange model. Polymarket is based outside the US, uses cryptocurrency, and operates a peer-to-peer model that carries higher regulatory risk for US users.
Should I move my sports betting to prediction markets?
Most casual bettors are better served by state-licensed sportsbooks that offer better consumer protections and faster withdrawals. Prediction markets are best treated as a supplement, not a replacement. See about DeucesCracked for our coverage philosophy.
Conclusion
The CFTC-versus-states prediction market battle is the most important regulatory fight in US gambling today, and its resolution will reshape the industry for the next decade. Whether through court rulings, congressional reform, or negotiated settlement, the federal-state question must be answered. For bettors and operators alike, the smart move is to stay informed, maintain optionality, and avoid concentrating capital in any single regulatory bet.
