Are prediction markets legal in Massachusetts?
Yes, for now. A state court granted the Attorney General an injunction against Kalshi’s sports contracts, but it was stayed pending Kalshi’s appeal to the Supreme Judicial Court, and the state agreed not to enforce against Polymarket US until that court rules. The SJC’s decision will set the rule for every platform.
Of the 26 platforms we review, 7 are open in Massachusetts, 5 with restrictions and 11 not at all; for 3 the terms do not say. Sports betting in Massachusetts: legal, licensed by the Massachusetts Gaming Commission (massgaming.com).
Not legal advice. Eligibility usually follows where you are when you trade, and a platform can refuse an individual account. Checked 29 September 2026.

stipulated stayNovig
US District Court, D. Mass. (Judge Saylor), Ludlow Exchange (Novig) v. Campbell (1:26-cv-13615). Novig's exchange sued on 6 Aug 2026; the case is stayed until the SJC decides Commonwealth v. KalshiEX (SJC-13906).
dismissal / PI deniedRobinhood, Interactive Brokers ForecastTrader
US District Court, D. Mass. (Judge Stearns), Robinhood Derivatives v. Campbell (1:25-cv-12578). The case was first dismissed as unripe on 13 Nov 2025 and reopened after Robinhood began offering sports contracts through ForecastEx.

stipulated stay (enforcement forbearance)Polymarket US
US District Court, D. Mass. (Judge Young), QCX LLC (Polymarket US) v. Campbell (1:26-cv-10651). Polymarket US sued on 9 Feb 2026. The AG agreed not to enforce against its sports contracts until at least 14 days after the stay ends, which is tied to the SJC's Kalshi ruling. The case is administratively closed.
stay of preliminary injunctionKalshi
Massachusetts Appeals Court (single justice). A single justice stayed the Suffolk PI pending Kalshi's appeal. This comes from a court filing signed by the AG and Polymarket US; the appellate docket (2026-J-0143) was blocked by a bot check. The appeal is SJC-13906.
preliminary injunctionKalshi
Suffolk Superior Court. The court granted the AG's PI and denied Kalshi's motion to dismiss; the PI was entered on 6 Feb 2026.

lawsuitKalshi
Massachusetts Attorney General (Andrea Joy Campbell). The AG filed a civil enforcement action against Kalshi in Suffolk Superior Court over sports event contracts.

ProphetX says it is “available nationwide” but publishes no excluded-state list; its help centre says access “is restricted from certain locations and IP addresses”.
