Wagers might generate between about $9 million and $61 million in state tax revenue if lawmakers decide to make Massachusetts sports betting legal, the Gaming Commission said Thursday in a white paper that mapped out how the Legislature might think about introducing another new form of gaming in the Bay State.

Massachusetts, like many other states, is waiting to learn if the U.S. Supreme Court will strike down any or all of the Professional and Amateur Sports Protection Act, which limits which states can offer legal sports betting. A decision in the case Christie v. National Collegiate Athletic Association could come as soon as next week, and states are trying to position themselves to jump at any opportunity presented by legal sports betting.

If the high court rules that states are free to legalize sports wagering, the decision to do so would belong to the Legislature and Gov. Charlie Baker. With that in mind, the Gaming Commission late last year set out to assemble information on the case, the current betting landscape and how other states are positioning themselves to take wagers.
