The market
Massachusetts launched online in March 2023, with six online sportsbooks going live together on launch day. A 20% online tax funds a competitive field. One rule to know: you can't bet on in-state college teams unless they're in a tournament.
What this means for matched betting
Offers come round regularly at a 20% tax. The ban on in-state college teams outside tournament play narrows which markets you can use, so check the fixture before you plan around it.
