Massachusetts online sportsbooks accepted $566.4 million in wagers in August, up 5% from July, as the regulated market maintained its run above $500 million in monthly betting activity.
The online total came from seven active licensees. Combined online and retail handle was $571.2 million, up 5.3% from $545.3 million in August 2025, according to Covers, marking the 13th consecutive month in which statewide sports wagering exceeded $500 million.
Online betting accounted for more than $566 million of the total, while retail activity fell sharply. The month did not include a full college-football weekend, as Week 1 games began in September, but Week Zero, NFL preseason and MLB wagering supported demand. August also followed the World Cup, which had lifted betting activity in June and July.
Sportsbooks recorded $48.5 million in gross revenue, their lowest monthly total in two years. Operators retained 8.4% of wagers, down from 10.5% a year earlier.
DraftKings took $275.1 million in wagers and held 8.5%. FanDuel generated $13.2 million in gross revenue from $144.5 million in bets, with a hold above 9%. Fanatics accepted $62.3 million in wagers, nearly 26% more than a year earlier, though its 7.2% hold was below the statewide rate.
BetMGM recorded just under $50 million in wagers and an 8.2% hold, while Caesars took $18.6 million and posted the lowest mobile win rate, below 6.5%. Bally Bet generated about $335,900 in gross revenue with an 11.7% hold.
Retail wagering was down 64% from August 2025, while the three land-based operators generated about $450,000 in combined win, down 35%. Encore Boston Harbor and Plainridge Park Casino each exceeded $2 million in retail handle and $200,000 in gross revenue, and in-person sportsbooks collectively held more than 21% of wagers.
The Massachusetts Gaming Commission reported about $47.1 million in taxable sports wagering revenue across seven mobile licensees and three retail licensees. The seven online operators were Bally Bet, BetMGM, Caesars Sportsbook, DraftKings, Fanatics Betting & Gaming, FanDuel and theScore Bet.
August wagering produced about $9.4 million in state tax revenue, nearly $2 million less than a year earlier. Still, Massachusetts had passed $100 million in sports-betting tax revenue for the year through August, with the World Cup months contributing nearly $24 million to state coffers.
Mobile operators are taxed at 20% of taxable sports-wagering revenue, compared with 15% for the three Category 1 casino licensees. Since retail sports betting began in January 2023 and online wagering followed in March 2023, the Commonwealth has collected about $500.4 million in sports-betting taxes and assessments.
