U.S. District Court for the District of Utah, 2:26-cv-00151
On appeal
On Aug. 4, 2026 Judge Robert J. Shelby granted summary judgment to Utah, holding that Utah's anti-gambling laws apply to Kalshi's sports event contracts and are not preempted by federal commodities law; Kalshi appealed to the Tenth Circuit (No. 26-4100), which denied an injunction pending appeal on Sept. 8, 2026.
The question
Whether the Commodity Exchange Act preempts Utah gambling or sports-wagering law as applied to event contracts listed on a CFTC-designated contract market.
Kalshi sued after Utah's HB 243 added proposition bets to the state's gambling definition. The court entered summary judgment for Utah, and Kalshi appealed.
