U.S. District Court for the Southern District of Ohio, 2:25-cv-01165
Injunction denied
Chief Judge Sarah D. Morrison denied a preliminary injunction on March 9, 2026 and the case is stayed pending appeal. The Sixth Circuit affirmed on Sept. 25, 2026, and Kalshi petitioned for rehearing en banc on Oct. 9, 2026.
The question
Whether the Commodity Exchange Act preempts Ohio gambling or sports-wagering law as applied to event contracts listed on a CFTC-designated contract market.
Kalshi sued Ohio regulators after state action against its sports contracts. The district court refused preliminary relief, and the Sixth Circuit affirmed.
The panel affirmed the denial of Kalshi's injunction in Ohio and vacated Kalshi's injunction in Tennessee and remanded. Kalshi has asked for rehearing. Sixth Circuit Nos. 26-3196 and 26-5235. Source: Opinion
