Overview
- A Raynham resident filed a class-action complaint in Suffolk Superior Court that says Kalshi took sports bets in Massachusetts without a state license.
- The plaintiff says he lost tens of thousands of dollars in about a month early in 2026 after placing sports wagers on Kalshi’s app and website.
- He seeks repayment of all losses for affected users, disgorgement of Kalshi’s fees and profits, and a court order blocking the platform from offering sports bets without a license.
- The complaints say Kalshi allows 18-year-olds to wager and lacks self-exclusion and simple guardrails like deposit or bet limits, leaving the plaintiff without tools he uses on licensed apps or through Robinhood, which hosts Kalshi markets.
- Kalshi points to 2020 federal approval from the Commodity Futures Trading Commission for its event contracts, while a separate suit by the Massachusetts attorney general won a preliminary shutdown order that is now paused during appeal.
