Utah files criminal gambling charges against Kalshi and its co-founders
Utah Attorney General Derek Brown filed criminal charges against KalshiEX LLC and its co-founders on October 28, accusing the prediction market of illegally promoting online gambling.
The charges landed a day after the US Commodity Futures Trading Commission sued to stop Utah from enforcing its anti-gambling laws against the company. Utah filed a civil lawsuit against Kalshi on October 20, seeking to block the platform's operations in the state and force it to geofence Utah users.
According to the charging documents, an undercover state agent opened a Kalshi account in September while confirming a Utah residence and then placed 12 wagers on sports-related events. Brown, a Republican, brought a total of 14 counts including one count of pattern of unlawful activity, twelve counts of online gambling promotion, and one count of general gambling promotion.
Financial stakes
The civil complaint estimates Kalshi collected between $30.5 million and $61.1 million from Utah users between February and mid-October 2026. Naming the co-founders personally raises the stakes considerably, as a criminal case puts named executives in the crosshires beyond just the company's financial risk.
A civil dispute puts a company's money at risk. A criminal case puts named executives in the crosshairs.
Legal battle escalation
The courts have so far leaned Utah's way. On August 4, a federal judge ruled that Utah's anti-gambling laws apply to Kalshi's contracts. The Tenth Circuit denied Kalshi's request for a stay of that ruling on September 8. The CFTC and the US Department of Justice then jointly sued Utah, arguing that the Commodity Exchange Act preempts state gambling laws when it comes to federally regulated contracts.
Utah is the tenth state to face legal action from the CFTC over similar jurisdictional questions about prediction markets and gambling law. Kalshi has characterized Utah's actions as political and as an overreach of state authority, emphasizing its status as a CFTC-approved designated contract market since 2020.
Industry implications
Kalshi's core defense rests on its regulatory status as a designated contract market, which it argues makes its event derivatives under federal oversight rather than gambling subject to state laws. Utah counters that contracts paying out based on sports outcomes resemble sports bets regardless of terminology.
For traders and investors, the key concerns are how courts handle the CFTC and DOJ preemption suit, whether Utah's criminal case proceeds amid the federal fight, and if other states follow Utah's lead with criminal charges. The undercover sting may prove most consequential, providing a template for other states to build cases against prediction markets.
