U.S. District Court for the Southern District of Ohio, 2:26-cv-01502
Pending
Complaint filed Oct. 16, 2026 under 42 U.S.C. 1983; assigned to Judge Douglas R. Cole. Summons issued; no ruling.
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.
Polymarket's U.S. exchange sued Ohio officials three weeks after the Sixth Circuit rejected Kalshi's preemption arguments in the Ohio case.
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
