Massachusetts sportsbooks had a standout performance in May, recording their second-highest monthly revenue this year, thanks in large part to favorable NBA postseason outcomes for operators. According to figures released by the Massachusetts Gaming Commission (MGC), the state’s online and retail betting platforms brought in a combined $82.5 million in gross revenue—marking a 40% increase compared to May 2024.
May’s total trails only January’s $96.4 million record but represents a strong showing for the growing sports betting market in the Bay State. This surge follows a broader trend observed across the country, where unpredictable results during the NBA playoffs helped sportsbooks produce over $150 million in operator revenue during April and May combined—a 36.9% bump from the same period last year.
Taxable revenue also mirrored this growth, exceeding $80 million for just the second time since online sports betting launched in March 2023. The result was a $16.1 million tax contribution for the state in May, pushing year-to-date tax revenue beyond $70 million.
Online Operators Continue to Dominate the Market
Online sportsbooks were responsible for the vast majority of activity, accounting for $645.7 million of May’s $655.8 million total handle. This figure is 11.7% higher than May 2024’s, though it dropped by 5% from April, continuing a month-over-month decline for the second straight time. Still, total bets in 2025 have surpassed $3.5 billion, outpacing last year’s $3 billion over the same five-month span.
Among operators, DraftKings solidified its lead in the state’s digital betting space. The Boston-based platform generated a $330.8 million handle, resulting in $42.4 million in revenue from a 12.8% hold. Though its handle slightly decreased from April, its revenue rose from $38.6 million.
FanDuel followed with a $171.9 million handle and delivered $23.5 million in revenue on a state-best 13.6% win rate—an impressive 27.7% increase over the previous month.
Other contenders included BetMGM with $49.2 million in wagers and $5 million in revenue, and Fanatics Sportsbook with $46.3 million in handle and $5.9 million in earnings. ESPN BET posted $2.7 million in revenue from $21.9 million, narrowly ahead of Caesars, which earned $1.7 million from $20.6 million. Bally Bet remained at the bottom of the list with a 4.34% win rate on $4.9 million.
Retail Betting, Casino Gaming Also See Gains
While overshadowed by digital platforms, retail sportsbooks also posted improved results. They recorded $1 million in revenue from a $10.1 million handle—reflecting a 10% hold, nearly double April’s 5.2%.
Encore Boston Harbor led among retail locations, collecting $588,397 on $5 million in wagers. Plainridge Park followed with $283,687 from $3.6 million, while MGM Springfield had a 10.4% hold on a $1.5 million handle.
In other state gaming activity, land-based casinos brought in $105.4 million in revenue during May—a 7.9% year-over-year increase. Encore Boston Harbor contributed $63.3 million, MGM brought in $25.4 million, and Plainridge Park followed with $16.6 million from slots. The state collected a total of $46.4 million in taxes, with $30.3 million from casino operations and the rest from sports betting.
