Is Sports Betting Legal in Massachusetts?

In short, yes, it is. Massachusetts sports betting is legal in both retail and mobile capacities. Here is a quick overview of the current options for sports gambling in Massachusetts.

Current Legal Standing of Massachusetts Sports Betting

Massachusetts sports betting online is live and legal, as is in-person sports betting. Massachusetts online sportsbooks launched in 2022 and are regulated by the Massachusetts Gaming Commission. The approved MA online betting law allows up to 15 licenses and places a 20% tax rate on gross revenue. Eight of these licenses are tied to a land-based partner, while the remaining seven are open to competitive bidding.

Only seven state-regulated MA online sportsbooks and three retail MA sportsbooks are live as of 2025. This gives bettors a fair number of choices to select from. There are even more options if you consider regulated MA sportsbooks licensed overseas.

Although close neighbors Rhode Island and New Hampshire only require bettors to be at least 18 years old, Massachusetts sports gambling laws require residents to be at least 21 to place sports wagers. Further, every sportsbook in Massachusetts uses geolocation software, so you must be inside state lines to use them.

Recent Massachusetts Sports Betting Legislation Changes

The sports betting bill, H3977, was initially passed by House lawmakers in July 2021. The bill includes open licensing, college betting, and a tax setup that splits retail and online. However, the Massachusetts Senate passed its version of the bill on April 8, 2022, adding stricter rules on advertising and college betting.

The bill’s final version, HB 5164, allowing retail and online sports betting in Massachusetts, was passed just before the legislative deadline. Governor Charlie Baker signed the bill into law, and retail and MA online betting sportsbooks launched soon after.

In November 2024, the Massachusetts Gaming Commission (MGC) discussed limiting individual bettors. Soon after, it proposed a partnership with the Massachusetts Council on Gaming and Health to launch a public awareness campaign about responsible gambling. On March 26, 2025, state Senator John Keenan, alongside some Representatives, filed a bill to address concerns about addiction (by imposing mandatory daily and monthly betting limits) and ban prop bets.

When Did Massachusetts Legalize Online Sports Betting

A bill to legalize sports betting in MA was passed in the final hours of the 2022 session, and Gov. Charlie Baker signed it on Aug. 10, 2022.

However, retail MA sports betting did not launch until January 31, 2023, with three Massachusetts sports gambling casinos accepting wagers. Mobile and MA online sports betting followed on March 10 of the same year. MA’s sports betting industry did exceptionally well in the same year, with gross gaming revenues of $152.6 million in March.

How Do the Gambling Laws in Massachusetts Compare with Neighboring States

HB 5164, also known as the Massachusetts Sports Wagering Act, includes several key features that may distinguish sports betting in MA from other states.

For example, the state imposes a 20% tax rate on Massachusetts sports betting online and a 15% tax rate for retail betting. Also, there’s an outright ban on in-state college team betting, except for tournament games.

Let’s examine the laws governing sports gambling in Massachusetts’ neighboring states more closely.

New Hampshire

New Hampshire sports betting became legal in 2019 with the passage of HB 480. Although the state has only three retail sportsbooks, its sports betting framework allows up to 10 retail sports betting locations. Online sports betting, though legal, is only offered by DraftKings sportsbook, which secured a near-monopoly with the New Hampshire Lottery.

Rhode Island

As with sports betting in Massachusetts, Rhode Island sports betting is legal online and in person. The state has only two retail locations, and you can only place wagers online via the Sportsbook Rhode Island app. It was one of the first states to legalize sports betting, only a month after the Supreme Court repealed the Professional and Amateur Sports Protection Act (PASPA).

Connecticut

Vermont

As with most of MA’s border states, Vermont sports betting is legal and live in 2025. However, it takes a different approach. Residents can only place wagers online. VT online sports betting was launched in 2024.

New York

Can You Play at Online Sportsbooks in Massachusetts?

Yes, you can. There are seven active Massachusetts sports betting sites you can play on. These sportsbooks offer betting odds on sports and horse racing with lucrative bonuses to boost your bankroll. However, they might not be the right fit for you if you are a college sports fanatic. MA sports betting sites do not offer betting lines on college teams outside of tournaments like March Madness. You also cannot place prop bets on college teams or players with regulated Massachusetts online sportsbooks.

So, how to sports bet in Massachusetts if you want to wager on college sports? Offshore sportsbooks! To be safe, play only on licensed and regulated offshore sportsbooks. These U.S. online sports betting apps are regulated – only outside the U.S. They are held to their regulatory bodies’ highest safety and security standards.

MA betting sites licensed by respected jurisdictions like Malta, Curacao, Panama, Anjouan, and Mwali also offer betting odds on niche sports betting categories like Politics and Entertainment. These odds are sometimes much higher than you can get with sports like the NBA and NHL, increasing your payout potential.

1. BetOnline – Best Overall Massachusetts Sports Betting Site; Top Spot for Parlays & Competitions

BetOnline is the best sportsbook for online sports betting in Massachusetts, bar none. This Panama-licensed sportsbook is one of the sharpest on the market, with early betting lines and rebet functionality. It is also one of the best crypto sports betting sites, with zero extra charge on crypto deposits and payouts.

You can place moneyline bets, spreads, totals, props, and parlays on 30+ sports on BetOnline, including less popular ones like entertainment and politics. The betting markets are deep, and the odds are competitive. For example, we found up to 67 betting markets in a live New England Revolution game. You can check out the mega parlays tab for parlays with 5,000+ odds or build yours using its parlay builder. It also offers odds boosts and live streams on the Celtics, Bruins, Red Sox, and Patriots.

BetOnline supports cards, bank transfers, and up to 16 cryptocurrencies, including meme coins like SHIB and TRUMP, for deposits. With the number of coins supported, it easily rivals the best no-KYC crypto sportsbooks. In addition. BetOnline is famous for its sports-specific bonuses and promotions.

Massachusetts Sportsbooks 2025 – Top MA Betting Sites

• Welcome Offer: 150% Up To $225
Massachusetts Sportsbooks 2025 – Top MA Betting Sites:  BN150

Sometimes the expansive nature of modern sportsbooks can be a little too overwhelming, and BetNow offers a welcome respite. This is particularly attractive for beginners, with the straightforward layout and primary focus on US major leagues providing a more straightforward approach. Throw in 2% cashback on all sports betting losses with no strings attached, and you’ve got a perfect place to begin or enhance your MA sportsbook journey.

As far as Massachusetts betting sites go, BetNow has slightly fewer sports with around a dozen. This isn’t really a negative, however, as the overwhelming majority of bettors don’t wager on niche things like handball or water polo anyway. And the sportsbook excels with the most popular options like NBA and other major leagues. Odds are also consistently at the top of the range – where Bovada had the Indiana Pacers at +310 in the NBA Finals Game #1, BetNow came in at +334.

Bettors have all the most popular deposit and withdrawal options, with Visa, Mastercard, and American Express alongside Bitcoin and Bitcoin Cash. BetNow has alluring bonuses too, notably offering a sliding welcome promo scale. Having the choice between the following is a nice touch:

• Crypto only 200% up to $200 (CRYPTO200)
• Fiat only 150% up to $225 (BN150)
• Fiat only 100% up to $500 (BN100)

3. BetUS – Free YouTube Analysis & Picks and Prediction Shows at this Massachusetts Sportsbook

• Welcome Offer: 100% sports sign-up bonus up to $2,000 + additional casino funds
Massachusetts Sportsbooks 2025 – Top MA Betting Sites: JOIN125

Established in 1994, BetUS is one of the oldest betting sites, highlighting its trustworthiness in the gambling community. It offers betting lines on popular sports among the Bay Staters, including the NBA, NHL, and MLB.

BetUS, licensed in Mwali, Union of Comoros, offers totals, point spreads, and totals on the Patriots, Bruins, Celtics, New England Revolution, and Red Sox. Perhaps more important is BetUS TV, which has YouTube shows like the NBA Show, College Basketball Show, and NFL Show, where the hosts discuss weekly picks and predictions.

There are several contests to participate in if you like a little competition. This includes Survivor Pools, Betting Squares, a Lottery Log-in, and Parlay Challenge. There are even more free-to-enter contests across all sports like Beat the Streak (Baseball) and Schools Out (Football).

BetUS lets you deposit money using credit cards, cash transfers, bank wires, or cryptocurrency. There are no fees for crypto deposits, and you can deposit between $20 and $50,000 daily. For other payment methods, the most you can deposit at once is $2,499. Withdrawals are also free; you can take out between $100 and $3,000 daily. Some of its bonuses you can use to bet on MA local teams risk-free include:

• 100% sports welcome bonus up to $2,000
• 150% crypto sports bonus up to $1,500
• 10% cash bonus

Popular Teams and Events to Bet On In Massachusetts

These are some of the most popular local teams backed by Bay Staters on the best MA sports betting sites.

New England Patriots

The New England Patriots are one of the most successful franchises in NFL history, thus having a large cult following in the Bay State. They are led by legendary quarterback and head coach Bill Belichick. Under Brady’s leadership from 2001 to 2019, the Patriots won six Super Bowl titles (2001, 2003, 2004, 2014, 2016, 2018) and appeared in nine Super Bowls.

Since his departure, the Patriots have entered a rebuilding phase and now look to promising rookie quarterback Drake Maye to potentially lead the next era of success. BetOnline is one of the best Massachusetts sports betting sites to wager on the Patriots with NFL-targeted bonuses, odds boosts on select Patriots games, and mega parlays.

Boston Celtics

The Boston Celtics, alongside the Los Angeles Lakers, are the most decorated team in NBA history. In 2024, they equalled the Lakers’ 18 Championship wins with a 4-1 Finals win over the Dallas Mavericks. The Celtics, powered by stars Jayson Tatum and Jaylen Brown, are now considered by many to be one of the most complete teams in the NBA.

They have become a perennial contender for the Eastern Conference Championship, and there’s no better place to back them than on MyBookie. The Curacao-licensed sportsbook offers low-entry fee  Bracket contests on the Playoffs, Finals, and March Madness with up to $10k prize pools.

Boston Bruins

The B’s are one of the NHL’s ‘Original Six franchises’ and the oldest team from the United States. They have made 20 appearances in the Stanley Cup Finals and won six championships (the 4th most Stanley Cup wins).

Injuries to key players like defenseman Charlie McAvoy and the mid-season trade of captain Brad Marchand impacted the team’s 2024-25 performance, ending an eight-year streak of making the Playoffs. Despite their recent downturn, the Bruins are still a great team on which to place moneyline and prop bets.

Boston Red Sox

The Red Sox, like the Celtics and Patriots, are another fine team from Massachusetts. They rank third in MLB history with nine titles, just behind the New York Yankees (27) and St. Louis Cardinals (11). Notably, their 2004 victory ended the infamous “Curse of the Bambino,” initiating a period of renewed success in the 21st century. They have won four more titles since then, the latest in 2018.

However, they appear to be rebuilding and didn’t make the playoffs in 2024. We recommend wagering on player prop bets if you must bet on the Red Sox. Popular bet options are fly ball bets on Nick Sogard and extra-base hits by Carlos Narvaez.

The Revolution has reached the MLS Cup final five times but has yet to secure a championship title. They’ve, however, won the U.S. Open Cup, SuperLiga, and Supporters’ Shield.

They are tied for the fewest goals conceded in the MLS, with only 10 goals against in 12 matches as of this writing. You may find value in betting on under goals for their opponents.

Responsible Gambling Resources in Massachusetts

Although gambling can be profitable, it is essential to bet responsibly. Set a budget and stick to it at all times. If you or anyone you know needs help with their gambling habits, check out the following free resources for support.

Conclusion: The Best MA Sportsbooks Online

There are up to 10 active online and retail sportsbooks in Massachusetts as of 2025. That’s a decent number to choose from. However, your options may be limited if you are promo gaming. Most regulated sports betting sites in Massachusetts no longer offer straight bet profit boosts, deposit matches, or no-sweat bets.

These bonuses and promotions are commonly available at the best Massachusetts sports betting sites. For instance, with a top Massachusetts sportsbook like BetOnline, you also get more betting categories, including college props, politics, and entertainment. In addition, sign up with BetOnline in 2025 and you can begin your MA sportsbook journey with up to $250 in free bets and no wagering requirements.
