Beyond the BetMGM Massachusetts welcome offer for new users, the sportsbook is also offering more sports betting promos for tonight's game and beyond. You can opt into these offers as an existing user or, as a new user, claim them after signing up:

• Golden Gift Card Sweepstakes: Deposit $25 in BetMGM gift cards before Oct. 31 to enter a drawing for a $10K cash bonus.
• Refer a Friend: Invite friends to join BetMGM, and you'll both get $100 in bonus bets when they sign up, deposit $100+, and bet $100 (min. -200 odds). 

If you want to take advantage of the welcome offer, you cannot add these additional offers until after you make your first bet. In other words, your first bet applies only to the welcome offer. 

You can use these offers on any bets after your first one.

Most online sportsbooks have the Celtics winning by 5-6 points. Compare BetMGM's odds to those at other sports betting apps here:

The Celtics' starting lineup looks very similar to the one that won the NBA Finals just a few months ago.

This game marks the Celtics' 2024-25 home opener at TD Garden in Boston, Mass. 

The only Celtics player expected to miss the season opener is center Kristaps Porzingis, who will be sidelined until at least December with a foot injury.
