Polymarket Sues Ohio Over Sports Betting Restrictions

Polymarket US has filed a federal lawsuit challenging Ohio's enforcement of sports betting laws against prediction market operators, arguing that the state's licensing requirements violate constitutional protections for interstate commerce. The complaint, filed on October 16, seeks preliminary and permanent injunctions preventing Ohio officials from taking enforcement action against the federally regulated platform. Polymarket argues that the Ohio Casino Control Commission's (OCCC) restrictions conflict with the Commodity Exchange Act (CEA), which places certain derivatives markets under the authority of the Commodity Futures Trading Commission (CFTC). The lawsuit follows cease-and-desist notices issued to ten prediction market businesses earlier this month.
