On 23 February, Kalshi filed a complaint in the US District Court for the District of Utah seeking declaratory and injunctive relief against senior state officials. The lawsuit accuses Spencer J. Cox, Derek Brown, and other state representatives of trying to block its federally regulated event contracts.
Kalshi argues that Utah’s threatened enforcement of anti-gambling statutes conflicts with federal commodities law. The filing maintains that any move to treat its contracts as unlawful gambling would intrude on federal authority.
The company relies on the Commodity Exchange Act, which grants the Commodity Futures Trading Commission exclusive jurisdiction over derivatives traded on designated contract markets.
The CFTC has publicly supported this view, but it’s still being proven in various court cases.
Utah legislative action and public statements intensify pressure
The legal clash follows a series of public remarks from Utah officials and fresh legislative activity targeting prop bets. Utah House Bill 243 amends the state’s criminal code to classify prop bets as illegal gambling.
It defines these wagers as bets placed on individual statistics or specific occurrences during athletic contests. This new bill creates a wider scope for classifying these wagers, which includes sports prediction markets.
Furthermore, the complaint refers to statements from Gov. Cox that businesses like Kalshi are illegal in Utah and multiple states could pursue action against them. The filing features an opinion article by Attorney General Brown declaring that prediction markets in the state are unlawful and outlining a plan to address them.
Kalshi argues that these comments, coupled with amicus briefs Brown signed in federal appellate courts, signal a credible threat of enforcement.
Federal preemption central to the dispute
The company mentioned that it reached out for assurances of non-enforcement from the Utah Attorney General’s office but has gotten no answers. Now, it aims to stop the state from initiating civil or criminal proceedings during the case through a temporary restraining order and preliminary injunction.
The complaint also argues that Congress vested the CFTC with exclusive oversight of futures and swaps markets to avoid inconsistent state regulation. Kalshi cites statutory provisions granting the agency sole jurisdiction over accounts, agreements and transactions involving swaps and commodity futures traded on approved exchanges.
Kalshi asserts that allowing Utah to apply gambling laws to federally authorised contracts would undermine the structure.
The filing references recent federal court rulings in Tennessee and New Jersey that provided preliminary injunctions blocking state officials from taking comparable action against Kalshi’s event contracts.
In those rulings, courts concluded that the company was likely to succeed on the merits of its federal preemption claims. Judges also found that the company faced irreparable harm if enforcement proceeded before the legal questions were resolved.
Kalshi seeks injunction and constitutional ruling
Utah law criminalises certain forms of gambling promotion while providing exceptions for lawful business transactions. Kalshi argues that trades executed on a CFTC-registered exchange qualify for that exemption.
The complaint aims for a declaration that Utah’s gambling statutes are unconstitutional as applied to Kalshi’s operations. It also asks the court to bar state officials from enforcing those statutes against its exchange in Utah. The case’s outcome will influence how other states approach prediction market platforms operating under CFTC supervision.
