In litigation
Utah beat Kalshi in federal court, expanded its gambling ban to cover proposition bets, and sued Kalshi in state court on October 20, 2026.
Kalshi sued Utah officials in February 2026 to block enforcement of state gambling law, and the legislature enacted HB 243 defining proposition bets as gambling, effective May 6, 2026. On August 4, 2026, Judge Robert Shelby granted summary judgment to Utah, finding that federal commodities law does not displace the state's gambling ban; the Tenth Circuit denied Kalshi an injunction pending appeal on September 8, and the appeal remains pending. On October 20, 2026, Attorney General Derek Brown sued Kalshi entities and two trading firms in state court, seeking an injunction backed by geolocation, fee disgorgement and restitution. No court has yet ordered Kalshi to stop serving Utah users.

The state seeks an order barring Kalshi from taking Utah wagers, enforced through a court-approved geolocation tool, plus fees it estimates at $30.6 million to $61.2 million and about $5.5 million in restitution for Utah users' losses.
