Massachusetts Amended Complaint: Kalshi Allegedly Offers Sports Betting to Users Under 21

Odaily Odaily reports that the Massachusetts Attorney General has received court approval to file an amended complaint against the prediction market platform Kalshi, adding allegations that Kalshi markets to users under the age of 21 through social media and campus campaigns, and has failed to take effective measures to prevent them from using the platform. Kalshi allows individuals aged 18 and older to create accounts and place bets on sports events. The case originated in September 2025, with state authorities accusing Kalshi of offering sports betting in violation of state law. The CFTC previously filed a brief in Massachusetts asserting exclusive jurisdiction over prediction markets, with Chairman Michael Selig stating that Congress has granted the CFTC sole authority to regulate the commodity derivatives market. Kalshi has not yet responded to requests for comment. (Cointelegraph)
