United States v. state
United States v. State of Minnesota
U.S. District Court for the District of Minnesota, 0:26-cv-02661
Injunction granted
PI granted July 27, 2026 by Judge Katherine M. Menendez together with the Kalshi and Polymarket US cases; DeFi Rate lists a pretrial conference on Oct. 13, 2026. No appeal by Minnesota found as of Oct. 21, 2026.
The question
Whether the CEA preempts Minnesota law as applied to event contracts on CFTC-registered exchanges, so that the state may be enjoined from enforcing it against them.
Filed the day after Minnesota's prediction-market ban was signed, the suit argued the law undermines the federal scheme, including by criminalizing weather contracts. The court enjoined enforcement against CFTC-registered exchanges.
Resolved
- Yes
Judge Menendez preliminarily enjoined enforcement of the ban against the exchanges that sued, days before its Aug. 1 effective date, in the federal, Kalshi and Polymarket US cases. D. Minn. No. 0:26-cv-02661. Source: Legal Sports Report
