Best Gambling Sites in Massachusetts 2026

172 platforms available across 16 categories in Massachusetts. Regulated by the Massachusetts Gaming Commission.

Legal data last verified April 7, 2026

Fact-checked 2026-04-07

Governor Charlie Baker signed H. 5164 in August 2022 legalizing sports betting. Retail books at Encore Boston Harbor, MGM Springfield, and Plainridge Park opened in late January 2023, and mobile operators including DraftKings, FanDuel, Caesars, and BetMGM went live on March 10, 2023.

The Massachusetts Gaming Commission licenses three categories: Category 1 (resort casinos), Category 2 (racetracks/simulcast), and Category 3 (online/mobile). Online sportsbooks face a higher 20% tax rate on gross sports wagering revenue, while in-person operators pay 15%. The MGC publishes detailed monthly reports broken down by operator and category.
