Challenge to Minnesota’s prediction-market ban

Statute enjoined; not in effectStatutory Challenge

Last updated August 16, 2026. Snapshot — not legal advice.

Overview

Minnesota became the first state to ban prediction-market platforms by statute (signed May 2026, set to take effect August 1). Before it took effect, a federal judge (Katherine Menendez, D. Minn.) preliminarily blocked the ban (late July 2026), so it is enjoined and not in force. The CFTC and the platforms (Kalshi, Polymarket) each sued the state; the CFTC track is docket-confirmed as United States v. State of Minnesota (0:26-cv-02661, before Judge Menendez). Litigation is ongoing; the ban is not currently enforceable. (This entry covers the broader/consolidated challenge before Judge Menendez, which has no single clean standalone caption to verify; captionVerified stays false.)
