Massachusetts’ regulated gaming industry recorded a modest downturn in March 2025, with the state’s three commercial casinos bringing in a combined $105.1 million in gross gaming revenue (GGR). This figure marks a 5.6% decline from the $111 million posted in March of the previous year, according to data released by the Massachusetts Gaming Commission (MGC).

The state’s flagship casino, Encore Boston Harbor (EBH), experienced a notable setback, generating $63 million in revenue—its lowest March performance since 2021 and a 10.5% year-over-year decline. In contrast, MGM Springfield and Plainridge Park Casino (PPC) each reported their strongest March figures in five years. MGM Springfield achieved $25.5 million in GGR, edging past its previous March high from 2024 by 1.2%. PPC posted a 5.8% annual gain, rising from $15.4 million in March 2024 to $16.5 million this year.

Slot machines accounted for $76.6 million of the total GGR, while table games contributed $28.4 million across the three casinos.

Tax structures vary by facility: PPC, designated as a Category 2 slots parlor, is taxed at 49% of its gaming revenue—82% of which supports local aid, with the remaining 18% funneled into the Race Horse Development Fund. MGM and Encore, as Category 1 resort casinos, are subject to a 25% tax rate, with those proceeds distributed across several state funds as mandated by gaming legislation.

Since their respective launches, the casinos have collectively contributed approximately $2.045 billion in tax revenue and assessments to the Commonwealth.

Sports Betting Revenue Remains Steady Despite Handle Records

Massachusetts’ sports wagering market generated $52.12 million in taxable sports wagering revenue (TSWR) during March, combining the totals from both in-person and mobile operators. This TSWR came from a staggering $772.4 million in total wagers—a new monthly record for the state. Of that handle, $761.8 million originated from mobile platforms, while just $10.6 million was wagered in retail sportsbooks at casino locations.

Despite the record handle, the state saw a drop in actual taxable sportsbook revenue compared to last year. March 2024 saw $12.6 million wagered in-person, with a taxable return of $731,000. This March’s taxable revenue from sportsbooks dropped significantly to $265,000, highlighting the volatility of operator margins.

DraftKings and FanDuel remained dominant in the mobile segment, reporting handles of $375.1 million and $208.4 million, respectively. Operators licensed under Category 3—including Bally Bet, Caesars Sportsbook, and Fanatics Betting & Gaming—are taxed at 20% of their TSWR. Meanwhile, Category 1 licensees like EBH, MGM, and PPC, which run physical sportsbooks, are taxed at a lower 15% rate.

All sports wagering taxes are split among five designated state funds: 45% to the General Fund, 27.5% to the Gaming Local Aid Fund, 17.5% to the Workforce Investment Trust Fund, 1% to the Youth Development and Achievement Fund, and 9% to the Public Health Trust Fund.

Operators are also permitted to carry forward negative monthly balances—such as when payouts and federal excise taxes exceed gross receipts—into future reporting periods under Massachusetts’ Sports Wagering Law.

Tax Revenue from Gaming Approaches Milestones

Since the inception of casino gaming in Massachusetts, total taxes and assessments from casino operations have reached approximately $2.045 billion. The state has also accumulated about $254.44 million in tax revenue from sports wagering since its staggered launch—retail betting started in January 2023, followed by online platforms in March 2023.

While overall monthly revenues saw a slight year-over-year decline, the March 2025 data shows resilience in segments of the market. MGM Springfield and PPC demonstrated growth potential, even as EBH’s numbers suggested a need for strategic reassessment. The sports wagering sector, meanwhile, continues to grow in volume, though profitability remains tightly linked to win margins.
