CFTC sues Minnesota to block prediction-markets law
The CFTC sued Minnesota to prevent enforcement of a law signed by Governor Tim Walz on 18 May 2026 that criminalises prediction markets. The commission argues that federal law gives it exclusive authority over event contracts; Minnesota Attorney General Keith Ellison said his office would defend the law. The CFTC is seeking preliminary and permanent injunctions before the law takes effect on 1 August.
The case could determine whether Minnesota can criminalise prediction-market activity regulated by the CFTC.
