A revived proposal in Massachusetts would dramatically revamp the face of legal online sports betting, as it calls for more than doubling the tax rate, eliminating VIP programs, banning prop and in-play bets, requiring affordability checks, and myriad other changes.

Backed by Sen. John Keenan, S 302 was first introduced last February, and had at least one hearing, but never got a vote. The bill carried over to the 2026 session, and on Jan. 15 the reporting date for it was extended to March 6. Keenan last fall publicly said he was sorry that he had voted to legalize sports betting in 2022. Platforms have been live since March 2023.
