Massachusetts is cracking down on betting firms that sidestep regulation. Attorney General (AG) Andrea Campbell has sued Kalshi for running sports wagering without a license. At the heart of the case is Kalshi sports wagering, which the state says looks like traditional betting but skips the rules.

• The AG filed the case in Suffolk Superior Court, saying Kalshi offered sports bets to Massachusetts customers without approval. The company never applied for a state license through the Massachusetts Gaming Commission.

• Kalshi runs “event contracts” on sports outcomes, covering moneylines, spreads, and totals. Regulators argue these contracts are sports bets by another name, actively promoted on TV, social media, and even Robinhood.

• Campbell said sports betting carries risks of addiction and financial harm, stressing operators must be licensed. “This lawsuit will ensure that if Kalshi wants to be in the sports gaming business in Massachusetts, they must obtain a license and follow our laws,” she noted.

• The Gaming Commission supported the move, warning that prediction markets often skip age checks, taxes, and consumer safeguards. Chair Jordan Maynard said the AG’s action enforces Massachusetts’ “rigorous standards.”

• The AG’s office also accused Kalshi of allowing 18- to 20-year-olds to bet despite the state’s 21+ rule. The platform allegedly lacks proper self-exclusion tools and betting limits, and the AG has asked the court to shut down Kalshi sports wagering in the state while the case is pending.
