Every Massachusetts Online Sportsbook (August 2026)

$2,650+ in signup value available in Massachusetts

Massachusetts permits online sports betting for adults 21 and over, with a stricter college rule than most: you cannot wager on Massachusetts college teams unless they are playing in a tournament, and player props on college games are banned outright. Signup offers below rotate frequently; always verify the current promotion in the app before claiming.

Online sports betting in Massachusetts is regulated by the Massachusetts Gaming Commission. You must be 21 or older. Gambling problem? Call 1-800-327-5050.

Massachusetts prohibits describing a sportsbook promotion as “free” or “risk-free” where you have to risk your own money to claim it. Offers below are described in the sportsbook's own terms — check what a promotion actually requires you to stake before claiming it.
