CFTC Sues Utah to Block State Crackdown on Kalshi Prediction Markets

The federal government sued Utah on Sunday, escalating a nationwide legal war over whether states can use gambling laws to shut down prediction markets that operate under federal oversight. The Commodity Futures Trading Commission and the U.S. Department of Justice filed the complaint in the U.S. District Court for the District of Utah, naming Attorney General Derek Brown and the state as defendants.

The suit asks the court for preliminary and permanent injunctions that would bar Utah from enforcing its gambling statutes against Kalshi and other platforms designated as contract markets by the CFTC. The federal government's core argument is that Congress granted the agency sole and exclusive authority to regulate these markets under the Commodity Exchange Act, leaving no room for conflicting state action.

"Congress entrusted the CFTC to be the federal regulator with sole responsibility to oversee these markets," CFTC Chairman Michael S. Selig said in a statement accompanying the filing. The agency contends that allowing individual states to act as de facto gambling regulators for federally licensed exchanges would fragment oversight and undermine the national derivatives framework.

The federal lawsuit arrived less than a week after Utah fired the first shot. On October 20, Attorney General Brown filed a state court complaint accusing Kalshi of operating an illegal gambling enterprise and demanding it halt operations in Utah. The state's lawsuit alleged that more than 32,000 Utah residents held Kalshi accounts as of mid-2026, that the platform had collected between $30.6 million and $61.2 million in trading fees from state users, and that those residents had absorbed roughly $5.5 million in trading losses.

Kalshi operates as a Designated Contract Market, a federally licensed exchange category that also covers traditional futures trading. The CFTC-supervised platform allows users to trade event contracts — binary bets on outcomes ranging from economic data releases to sports results. Utah's constitution contains some of the country's broadest prohibitions on gambling, making it a particularly aggressive enforcement environment for the emerging prediction market industry.

The Utah lawsuit is the tenth such action the CFTC has brought against a U.S. state. The agency has previously sued New York, Kentucky, Rhode Island, Arizona, Minnesota, Wisconsin, New Mexico, Connecticut, and Illinois on substantially similar preemption grounds, reflecting a coordinated federal strategy to establish that state gambling authorities cannot reach platforms operating under its license.

The legal terrain, however, is not entirely favorable to Washington. A federal judge ruled in August that federal commodities law does not automatically prevent Utah from enforcing its gambling prohibitions specifically against Kalshi's sports-event contracts, a decision that cut against the CFTC's preemption theory. Kalshi appealed that ruling and lost in September, leaving the question of sports-linked contracts in legal limbo even as the broader federal-state standoff intensifies.

The split between sports contracts and other event contracts may prove central to how courts ultimately draw jurisdictional lines. Prediction markets that cover financial indicators or political outcomes occupy different legal territory than those tied to athletic competition, where state gambling commissions have historically claimed authority.

For Kalshi, the stakes extend well beyond Utah. The company has been locked in simultaneous litigation across multiple states while simultaneously expanding its product lineup and user base. A favorable federal ruling in Utah would establish persuasive precedent in the other nine state battles and could effectively settle the preemption question for the industry.

The broader prediction market sector, which has drawn significant venture investment and user growth since Kalshi won a landmark CFTC battle over congressional-outcome contracts in 2023, is watching the litigation closely. Industry participants argue that fragmented state enforcement creates compliance uncertainty that chills innovation. State gambling regulators counter that federal licensing does not give technology platforms a blank check to circumvent consumer-protection laws enacted by state legislatures.

The U.S. District Court for the District of Utah has not yet set a hearing date on the federal government's request for a preliminary injunction. How quickly the court acts could determine whether Utah's enforcement actions against Kalshi remain paused during the litigation or proceed in parallel with the federal case.
