Meilleurs Sportsbooks en Massachusetts 2026

Massachusetts took its time on sports betting. After years of legislative debate, Governor Charlie Baker signed H.5164 into law in August 2022, and the Massachusetts Gaming Commission spent the next seven months drafting regulations and vetting operators. Retail sportsbooks at Encore Boston Harbor, MGM Springfield, and Plainridge Park opened on January 31, 2023. Mobile wagering followed on March 10, 2023, timed deliberately to capture the NCAA tournament. Mobile operators pay a 20% tax on gross gaming revenue, while retail books pay 15%. The state explicitly prohibits wagering on Massachusetts-based college teams unless they are participating in a tournament involving four or more teams. Bettors must be 21 or older and physically inside the Commonwealth. The market has consistently produced among the highest per-capita handle in the US, and the Gaming Commission has been notably aggressive on advertising standards and responsible gaming enforcement.
