Licensed sportsbooks

All 6 sportsbook-category platforms and all 3 DFS/sweeps platforms we cover operate in Massachusetts. Sportsbooks are licensed by the state and carry a 21 minimum; DFS and sweepstakes platforms operate under different rules and may admit players at 18.

Prediction markets

Event contracts are regulated federally by the CFTC rather than state by state, so a CFTC-designated exchange can be available where no state sportsbook licence exists. Availability still varies: individual exchanges apply their own geofences, and pending litigation has changed access in several states at short notice.

Kalshi, Polymarket, OG Markets are not currently accessible from Massachusetts in our coverage. ProphetX is; availability is subject to change, so verify before signing up.
