Sports Betting in Massachusetts
Massachusetts launched mobile betting in March 2023 and immediately put up $200M+ in first-month handle, aided by a sports-obsessed Boston market that includes DraftKings' own headquarters. The Patriots, Celtics, Red Sox, and Bruins collectively make Boston one of the most year-round-bettable cities in the country. A 20% operator tax is on the high side, so promotional activity has compressed faster than in lower-tax neighbors.
