Federal court allows Utah to enforce gambling laws against Kalshi
A US District Judge has ruled in favor of a Utah Governor and State Attorney General, rejecting prediction market platform Kalshi’s claim that federal law preempts the state from enforcing its anti-gambling laws against prediction markets.
Kalshi had argued that the Commodity Futures Trading Commission (CFTC) has the sole authority to regulate its event contracts, while Utah argued that the contracts constitute gambling under state law.
In the ruling, District Judge Robert Shelby said, “It would be inconsistent for Congress to allow states to regulate their gambling laws but to simultaneously require states to provide citizens access to every event contract, including those that constitute gambling under state law.
Kalshi has already filed an appeal against the ruling, which does not immediately prevent Utah residents from using the Kalshi site or other prediction market platforms, including Polymarket.
In a statement, Attorney General Derek Brown said his office intends to enforce Utah’s gambling laws, adding, “offering online gambling to anyone in the state is a third-degree felony.”
Utah’s legislature passed HB243 earlier this year, which clarified that betting on individual actions, statistics, occurrences, or non-occurrences is considered gambling under state law.
The decision adds Utah to a growing number of states that are engaged in legal disputes over prediction markets. Similar cases are active across at least 17 states, with conflicting court decisions likely to be resolved through higher federal courts or the Supreme Court.

The Backstory
Utah ruling sharpens the state-by-state fight
The Utah decision marks a significant turn in the widening legal fight over whether sports and other event contracts offered by prediction-market platforms are federally regulated derivatives or online gambling products subject to state law. Kalshi, a federally registered Designated Contract Market, has argued that the Commodity Exchange Act gives the Commodity Futures Trading Commission exclusive authority over its contracts. Utah countered that the products meet the state’s definition of gambling and can be restricted under its criminal laws.
District Judge Robert Shelby’s ruling rejected Kalshi’s preemption argument, finding that federal commodities law does not automatically displace state gambling enforcement. The decision gives Utah officials room to pursue the company under a legal framework that treats wagers on individual actions, statistics, occurrences or non-occurrences as gambling. It also adds pressure to a fragmented national landscape in which courts have reached different conclusions on similar facts, increasing the likelihood that appellate courts will be asked to settle the issue.
The case carries particular weight because Utah has no legal sports betting market. In states with licensed sports wagering, regulators have argued that Kalshi and similar platforms are bypassing licensing, age-verification, tax and responsible-gambling rules. Utah’s position is broader: It views the underlying activity as illegal regardless of whether it resembles the offerings of regulated sportsbooks elsewhere.
Kalshi moved first after Utah officials signaled a crackdown
Kalshi did not wait for Utah to bring an enforcement action. The company filed a preemptive federal lawsuit against Gov. Spencer Cox, Attorney General Derek Brown and other state officials, saying their public statements showed an imminent effort to block its business. In its complaint, Kalshi cited comments from Cox predicting broad state litigation against prediction-market companies and saying the businesses were illegal in Utah.
The lawsuit came as Utah lawmakers and officials were intensifying scrutiny of gambling-like products. Earlier this year, the state advanced legislation aimed at prop bets and in-play betting, initially viewed as targeting major sportsbook operators such as DraftKings and FanDuel. Kalshi argued that officials had expanded that campaign by mischaracterizing federally regulated event contracts as illegal gambling. The company said its markets fall under CFTC oversight and cannot be prohibited by state officials simply because they involve sports outcomes or other contingent events.
Utah’s response reflected a central state argument now appearing across the country: A federal registration cannot be used to transform gambling into commodities trading for purposes of state law. The state also pointed to HB243, which clarified that betting on individual actions or events may constitute gambling. Shelby’s ruling accepted enough of that reasoning to allow Utah to enforce its laws, even as Kalshi appealed.
New York and Massachusetts added momentum for states
Utah’s win follows a series of state actions that have tested Kalshi’s preemption theory. New York has taken one of the most aggressive approaches, suing the company for allegedly operating an illegal, unlicensed gambling business. In New York’s lawsuit against Kalshi, Gov. Kathy Hochul and Attorney General Letitia James alleged the platform allowed users to wager on sports, elections, culture and other events without approval from the New York State Gaming Commission.
New York officials said Kalshi’s markets involve uncertain outcomes outside a bettor’s control, bringing them within the state’s definition of gambling. They also emphasized consumer-protection concerns, including access for users ages 18 to 20, while New York’s mobile sports betting market is limited to customers 21 and older. The state is seeking to halt Kalshi’s operations, obtain restitution and impose financial penalties tied to the company’s profits.
Kalshi’s fight in New York had already suffered a setback when US District Judge Analisa Torres denied its bid for a preliminary injunction against state gambling enforcement. Kalshi immediately appealed, as detailed in its challenge to the New York ruling. Torres found that New York’s gambling laws were not superseded by the Commodity Exchange Act as applied to sports event contracts, a conclusion that closely parallels the reasoning now seen in Utah.
Massachusetts has also complicated Kalshi’s federal strategy. Attorney General Andrea Campbell sued the company in state court over sports prediction markets, making Massachusetts one of the first states to bring such an action through its attorney general. Kalshi tried to move that case to federal court, but Judge Richard G. Stearns rejected the effort and returned the matter to Suffolk County Superior Court. The decision in the Massachusetts remand fight narrowed Kalshi’s ability to reframe state gambling claims as inherently federal disputes.
CFTC involvement cuts both ways
The CFTC’s role is central but not decisive in every courtroom. Kalshi has relied on its federal status to argue that event contracts must be governed by a single national regulatory framework. That position has found support in some settings, particularly where courts or regulators have focused on the Commodity Exchange Act’s goal of consistent access to derivatives markets.
Michigan illustrates the tension. After an Ingham County judge temporarily blocked Kalshi from offering sports event contracts, the CFTC ordered the company to honor pending trades from Michigan residents rather than cancel them. The agency said federally registered exchanges must operate as a single national market and cannot deny access based solely on state residence. Michigan Attorney General Dana Nessel’s office objected, saying the order undermined the state’s authority to regulate online sports betting and enforce tax law. The dispute, described in Michigan’s response to the CFTC order, shows how federal market rules can collide with state gambling policy.
That collision has not produced uniform outcomes. Kalshi has won temporary relief or favorable rulings in some jurisdictions, while losing in others. Polymarket, another prediction-market operator, has faced its own setbacks, including in Michigan, where a federal judge denied a preliminary injunction and found its sports-event contracts did not fall within CFTC protection in the way the company claimed.
Sports contracts changed the stakes
Prediction markets long existed in a narrower policy debate around elections, economics and public events. The rapid expansion into sports outcomes changed the legal and political stakes. For state regulators, sports contracts resemble wagers placed through mobile sportsbooks, often without the licensing conditions imposed on operators in legal betting states. Those conditions typically include tax payments, age limits, advertising rules, integrity monitoring and tools aimed at problem gambling.
Kalshi’s model challenges that structure. If its sports contracts are treated as federally regulated swaps or event contracts, the company could offer products nationally without obtaining separate gambling licenses in each state. That would create a competitive advantage over licensed sportsbooks and weaken state control over markets that have been built through detailed legislation and local regulatory oversight.
States also see a consumer-protection gap. New York has focused on underage access and gambling addiction. Michigan has emphasized tax compliance and the obligation of companies operating in the state to follow state law. Utah, where gambling is broadly prohibited, has framed the issue as a direct threat to its policy choice to keep online gambling out of the state.
Appeals may define the market’s future
Kalshi has appealed the Utah ruling, ensuring the dispute will continue beyond the district court. The company is also pursuing appellate relief in New York and fighting state actions elsewhere. With similar cases active across many states, the central question is no longer confined to one platform or one product category. It is whether federal commodities law can coexist with state gambling laws when event contracts function like wagers on sports and other outcomes.
The immediate practical effect in Utah is limited because the ruling does not automatically block residents from accessing Kalshi or rival platforms. But the legal effect is substantial: It gives state officials support for enforcement and adds another ruling against Kalshi’s broad preemption argument. If appellate courts split, the issue could become a candidate for Supreme Court review.
For prediction markets, the stakes are existential. A federal victory would support a national model with CFTC oversight at its core. A state victory would force platforms to confront a patchwork of gambling laws, licensing systems and outright bans. Utah’s ruling pushes the balance toward state authority, at least for now.
