Massachusetts sports betting: legal sportsbooks & rules for 2026

Is sports betting legal in Massachusetts?

Yes. Governor Charlie Baker signed the Commonwealth's sports wagering law on August 10, 2022 after several years of House-Senate disagreement over licensing, advertising and college sports.

• Massachusetts then used a staged launch.
• In-person betting began January 31, 2023 at the state's three casino properties, while approved online operators began taking mobile wagers on March 10, 2023.
• The Massachusetts Gaming Commission, or MGC, regulates both channels.

The Massachusetts approach is notable because the market is not simply an unlimited commercial free-for-all. Chapter 23N creates Category 1 licenses for casino properties, Category 2 licenses for qualifying racing or simulcast facilities, and Category 3 licenses for mobile platforms. Category 1 operators can connect to as many as two individually branded mobile platforms, Category 2 operators can connect to one, and the MGC may award no more than seven Category 3 licenses that are not tethered to a Category 1 or Category 2 license.

For bettors, the most important eligibility rule is simple: you must be at least 21 and physically located inside Massachusetts when a mobile wager is placed. Residency is not required. The sportsbook's geolocation system checks location at wager time, so a Massachusetts resident who crosses into another state is governed by that state's market instead.

Legal Massachusetts sportsbook apps

The MGC's July 2026 revenue reporting lists seven active Category 3 mobile operators. That current lineup is more useful than older lists that still include WynnBET, Betr or the ESPN BET name. PENN's Massachusetts product now operates as theScore Bet, following the nationwide December 2025 rebrand from ESPN BET.

The MGC voted in April 2026 to reopen the sports wagering licensing process after a request from bet365, but a notice of intent is not the same thing as an approved license or launch. The MGC's July revenue reports still show seven active online operators. That distinction matters because operator counts can change faster than evergreen state guides are updated.

Which sports can you bet on in Massachusetts?

Legal Massachusetts sportsbooks cover the major professional leagues and a broad range of international events. Boston's sports calendar gives the market unusually strong year-round local interest: the Patriots, Celtics, Red Sox, Bruins and Revolution span the NFL, NBA, MLB, NHL and MLS, while tennis, golf, combat sports, motorsports and international soccer add substantial off-season depth.

The college rules need more care than the professional-sports rules. A sportsbook may not offer a wager on a Massachusetts college team unless that team is involved in a collegiate tournament.

• Once a Massachusetts team has actually qualified for a tournament, tournament-related wagers may be offered.
• The MGC also explains that a tournament physically held in Massachusetts is not automatically prohibited just because of its location.

Separately, state law excludes sports wagers whose outcome depends on the performance of an individual athlete in a collegiate event. That means college player props and individual-collegiate-athlete award markets such as Heisman or Wooden Award wagers are prohibited even when the underlying team is from outside Massachusetts.

Bet types & live betting in Massachusetts

For approved events, Massachusetts sportsbooks offer the familiar menu of moneylines, point spreads, totals, team props, futures, parlays and live wagering. Our types of sports bets guide explains how each format settles, while understanding odds and lines covers American odds and implied probability.

With seven regulated apps, Massachusetts gives bettors enough competition to compare prices rather than accepting the first line displayed. That makes line shopping especially relevant for frequently bet markets such as NFL sides, NBA player markets, MLB moneylines and NHL totals. Read our parlay guide and live betting guide before using the higher-variance formats.

Retail sportsbooks in Massachusetts

Massachusetts currently has three active casino sportsbooks: Encore Boston Harbor in Everett, MGM Springfield in Springfield and Plainridge Park Casino in Plainville.

• All three began taking retail sports wagers on January 31, 2023.
• The law also creates a Category 2 path for qualifying racing and simulcast facilities, including Raynham Park and Suffolk Downs, but neither is an active retail sportsbook as of September 2026.

Mobile registration is fully remote, so retail betting is optional rather than a prerequisite. You can create an approved sportsbook account online, complete identity checks and fund it without driving to a casino. You still must be physically inside Massachusetts when you place a mobile wager.

Where Massachusetts stands on online casino gaming

Massachusetts does not have legal real-money online casino gaming as of September 2026. The supplied draft described an internet-gaming bill as actively advancing, but the official legislative history has moved beyond that point.

• Senate Bill 235 was accompanied by a study order on March 9, 2026, while House Bill 4431 was accompanied by a study order on March 23, 2026.
• Neither became law.

That does not mean iGaming is permanently off the table.

• The proposals show continued legislative interest in a regulated online-casino framework overseen by the Massachusetts Gaming Commission, but there is no enacted launch date and no legal licensed real-money online casino market today.
• A state guide should therefore distinguish between a bill being discussed and a market that bettors can actually use.

How Massachusetts compares to other states

Massachusetts is neither a low-tax open market nor a monopoly. Its online sports wagering rate is 20% of adjusted gross receipts, while in-person wagering is taxed at 15%.

• That is higher than Michigan's 8.4% sportsbook rate and Arizona's 10% online rate, but below the top rates faced by large operators in Illinois and far below New York's 51% mobile structure.
• The result is a middle-ground market: enough operator competition to support line shopping, paired with relatively demanding licensing and compliance standards.

Another Massachusetts difference is regulatory transparency. The MGC publishes monthly operator-level revenue and maintains public records for licensees, enforcement actions and house rules.

• For consumers, that does not guarantee better odds, but it does make the market easier to audit and compare.
• It also helps distinguish active operators from brands that have exited or merely expressed licensing interest.

How to sign up for a Massachusetts sportsbook

A legal sportsbook account can be opened remotely. The exact interface differs by operator, but the core compliance workflow is similar across Massachusetts apps. You should expect identity verification and location checks before wagering is enabled.

Taxes on winnings & sportsbook revenue

Sports betting winnings are generally taxable income, and state and federal rules can both apply. Reporting thresholds for a Form W-2G do not mean winnings below the form threshold automatically become non-taxable. Your own filing position depends on your circumstances, so this guide is not a substitute for tax advice from a qualified professional.

On the operator side, Massachusetts law imposes a 15% excise on adjusted gross receipts from in-person sports wagering and a 20% excise on adjusted gross receipts from mobile applications and other approved digital platforms. Those rates affect the economics of sportsbook competition and promotion even though bettors do not pay the operator excise directly at the betting window.

Responsible gambling resources in Massachusetts

Massachusetts places unusual public emphasis on responsible gambling.

• The Massachusetts Gaming Commission supports GameSense, a player-focused program designed to make gambling information and safer-play tools easier to understand.
• Legal operators also provide account-level controls such as deposit limits, time-related tools and cooling-off or self-exclusion options under the state's regulatory framework.
