Massachusetts AG Expands Kalshi Lawsuit, Targets Youth Marketing

Massachusetts AG files amended suit against Kalshi, alleging the prediction market targeted under-21 users via social media and campus ads.

Massachusetts Attorney General Andrea Campbell isn't letting up on Kalshi. After a court granted permission Tuesday, the AG's office filed an amended lawsuit against the prediction market platform, escalating the legal fight over what regulators say amounts to illegal sports betting.

The new complaint packs a harder punch. Prosecutors are now alleging Kalshi went after users under 21 years old — a direct shot at the company's marketing strategy on social media and, notably, on university campuses. That's a damaging detail. College campuses mean young, financially inexperienced users, and regulators know exactly what story that tells a judge.

This amended filing comes on the heels of a prior court ruling that gave the AG the green light to expand the case. That matters because it signals the court isn't dismissing the state's concerns outright — the legal pressure on Kalshi is real and building. For traders who have been using Kalshi's political and sports-adjacent contracts, this is a situation worth watching closely. Regulatory crackdowns on prediction markets don't stay contained to one state.

Kalshi has positioned itself as a federally regulated prediction market operating under CFTC oversight, but state-level regulators have been aggressive in challenging that framework. Massachusetts is one of the loudest voices arguing that some of these contracts cross the line into sports gambling territory — which requires separate state licensing and consumer protection guardrails. The youth marketing angle gives the AG a compelling narrative that goes beyond legal technicalities.

If you trade on prediction markets or have money sitting on Kalshi contracts, keep this case on your radar. State-level legal fights like this one can move fast and reshape what's available to retail traders overnight. Continue reading at Cointelegraph.
