The Commodity Futures Trading Commission filed an amicus brief supporting Kalshi in its appeal against Ohio, arguing that the state exceeded its authority by ordering the company to halt sports event contracts listed on a designated contract market. The agency said prediction markets fall under CFTC jurisdiction and described Ohio’s action as regulatory overreach. The dispute could have broader implications for Kalshi, Polymarket, and the wider event contract market by clarifying whether these products are governed at the federal level or subject to state intervention.
