The market
Massachusetts launched online in March 2023, with a notable rule banning betting on in-state college teams unless they are in a tournament. A 20% online tax funds a competitive field. Six online sportsbooks went live together on launch day.
What this means for matched betting
Massachusetts is competitive at a 20% tax, with offers on a regular cadence. The rule against betting on in-state college teams outside tournament play narrows which markets you can use, so check the fixture before you plan around it.
Figures are indicative and can change as markets evolve. Always confirm current rules, tax and the legal age with the MGC before you bet.
