Prediction markets: CFTC sues Minnesota over pioneering ban

The U.S. Commodity Futures Trading Commission (CFTC) has filed suit against the state of Minnesota and Governor Tim Walz seeking to block a newly enacted law that would make operating or facilitating prediction markets a felony. The agency is asking a federal court for a preliminary injunction to prevent the statute from taking effect on August 1, 2026.

Minnesota’s law broadly criminalizes the operation, facilitation and promotion of prediction market activity, explicitly covering contracts tied to sports, political events and weather outcomes. The CFTC’s complaint argues these “event contracts” fall under federal oversight as derivatives and that state criminalization intrudes on the exclusive federal regulatory framework established by Congress. CFTC Chairman Michael S. Selig said the law would “turn lawful operators and participants in prediction markets into felons overnight.”

While the move does not immediately affect traded prices on traditional exchanges, it heightens legal uncertainty for platforms such as Kalshi and Polymarket and for firms that provide payments, distribution or media partnerships. A successful injunction for the CFTC would reinforce federal preemption and protect the operational scope of federally regulated event-contract markets; a contrary ruling could empower state-level restrictions and fragment access across jurisdictions.

The dispute is the latest chapter in a national jurisdictional fight. The CFTC has recently taken similar legal action challenging state attempts to apply gambling statutes to prediction markets in several states, arguing consistently for federal exclusivity over these derivative-like products. Minnesota’s statute has been described by the agency as the most aggressive state action to date because it also targets weather- and crop-related contracts used by commercial hedgers.

Legal analysts and market watchers say the immediate question is whether the court will grant the CFTC’s preliminary injunction. A ruling in the agency’s favor would likely stall state enforcement efforts and set precedent for other federal challenges; if the court denies relief, platforms may face a patchwork of state-level prohibitions with significant implications for risk management products relied upon by agricultural and weather-exposed businesses.
