Kalshi today lost a major ruling over whether it can evade state gambling laws, as a federal appeals court found that Nevada can stop the prediction market from allowing sports bets. While the Trump administration is trying to help prediction markets avoid state regulation, a panel of three Trump-appointed judges unanimously ruled against Kalshi in today’s decision from the US Court of Appeals for the 9th Circuit.
The Nevada Gaming Control Board today said the 9th Circuit “emphatically reject[ed] the view that the federal Commodity Exchange Act preempts application of Nevada’s gaming laws to sports-event contracts offered by Kalshi, Crypto.com, and Robinhood.” Nevada Governor Joe Lombardo, a Republican, said that “prediction markets offering sports-event contracts constitute gambling and must comply with Nevada’s gaming laws and regulatory framework.”
The judges affirmed a district court order that let Nevada enforce state laws against Kalshi’s sports-related event contracts.
“KalshiEX, LLC advertises itself as ‘the first app for legal sports betting in all 50 states,’” wrote Judge Ryan Nelson. “As the volume of activity on Kalshi’s ‘sports betting’ platform ballooned, the Nevada Gaming Control Board sent a cease-and-desist letter notifying Kalshi that it was violating Nevada statutes and gaming regulations. Kalshi sought injunctive relief, arguing that it is not a legal sports betting platform but a designated contract market under the Commodity Exchange Act (CEA) offering legal sports event contracts. Kalshi argues that the Commodity Futures Trading Commission (CFTC) has exclusive regulatory authority over its sports event contracts and, therefore, Nevada’s gaming regulations do not apply.”
