Kalshi, a prediction markets platform, has filed a lawsuit against the state of Minnesota following the signing of a new law by Governor Tim Walz that restricts prediction markets. The law, set to take effect in August, has prompted Kalshi to challenge its legality, arguing that it unfairly targets their operations. This legal action comes on the heels of a separate lawsuit filed by the Commodity Futures Trading Commission (CFTC) against Kalshi, highlighting the increasing regulatory scrutiny faced by prediction markets. Kalshi's lawsuit aims to prevent the enforcement of the Minnesota law, which they claim could significantly impact their business model and the broader prediction market industry.
