The Massachusetts Attorney General has received court approval to amend its complaint against prediction market platform Kalshi, alleging the company marketed sports betting services to users under 21. The amended complaint claims Kalshi targeted young users through social media and college campuses, failing to implement measures to prevent underage participation. Kalshi permits individuals aged 18 and older to create accounts and engage in sports betting, which state authorities argue violates Massachusetts law. The case, initiated in September 2025, has seen the CFTC assert its exclusive jurisdiction over prediction markets, emphasizing its regulatory authority over commodity derivatives markets. Kalshi has yet to comment on the allegations.
