Kalshi sues to block Minnesota prediction market ban
Kalshi sued Minnesota in federal court on May 27 to block the state's new ban on prediction markets. It asked for a temporary restraining order to stop the law before it takes effect August 1. The suit names Gov. Tim Walz and the state's gambling regulators.
Minnesota's Senate File 4760, signed May 19, made it the first state to outlaw event contracts on sports, politics, and other outcomes. Kalshi argues the federal Commodity Exchange Act gives the CFTC exclusive control, so the state law violates the Supremacy Clause.
The CFTC sued over the same law days after Walz signed it. Kalshi's filing opens a new front in federal court.
