March Madness Futures Odds in Massachusetts

We’ve explained how to unlock $3,850 in potential betting bonuses from Massachusetts online sportsbooks. Let’s now look at futures bets you can make on March Madness in Massachusetts.

Futures odds are available on teams to win the 2023 NCAA Tournament. Houston is the consensus betting favorite to win it all.

Average Odds
Chance of Winning
7 Day Change
14 Day Change
21 Day Change

Caesars Massachusetts had the best available odds on Houston at +550. This raises an important point: Be sure  to shop around several sportbook apps for the best odds. Savvy sports bettors will register with multiple online sportsbooks to ensure they find the most advantageous odds for their bets.

At odds of +600, a $100 bet on Houston will pay out $700 ($600 in winnings and your $100 stake back) if the Cougars win. You don’t want to bet Houston at +550 or +475 when you can get the Cougars at +600.

Always compare prices being offered at top sports betting apps in Massachusetts before making your bets!
