Michigan’s commercial and tribal online gambling operators generated $337.6 million in combined gross receipts in August, a 2.5% decline from July’s $346.1 million, according to the Michigan Gaming Control Board. The official total, covering internet casino games and online sports betting, was slightly higher than the $336 million figure reported by The Lines.
Internet gaming supplied $303 million of August gross receipts, virtually unchanged from $302.8 million in July. Online sports betting generated $34.6 million, down from $43.4 million a month earlier. As we reported Sept. 18, the August iGaming result kept Michigan’s online-casino market above $300 million in monthly revenue for a sixth consecutive month.
On an adjusted-gross-receipts basis, the combined market produced $315 million. iGaming AGR was $290.8 million, up 0.1% from July and 17.6% from a year earlier, while sports betting AGR fell 21.4% month on month and 29.3% year on year to $24.2 million.
Sportsbooks accepted $330.5 million in online wagers, down 7% from July’s $355.2 million. The Lines attributed the weakening sports-betting figures to the end of the FIFA World Cup, after wagering rose by more than 20% in June as the tournament began. August’s handle was also below the $338.9 million recorded in August 2025.
The August combined gross-receipts total nonetheless exceeded the $312.5 million reported a year earlier. That increase reflected the expansion of internet gaming, whose August gross receipts rose from $263.3 million in 2025, while online sports-betting gross receipts fell from $49.3 million.
Operators submitted $62.8 million in taxes and payments to the state during August. Detroit’s three casinos paid nearly $13.9 million in wagering taxes and municipal services fees to the city, while tribal operators made $8.5 million in payments to their governing bodies.
Michigan had 15 authorized commercial and tribal online-gambling operators in August. All 15 offered iGaming and 13 offered online sports betting.
