Michigan’s 15 online casino operators generated just over $303 million in August, marking a sixth consecutive month in which the state’s iGaming market cleared $300 million.
The total was 15.1% higher than the $263.3 million recorded in August 2025. Although revenue rose from a year earlier, it was Michigan’s slowest year-over-year growth rate of 2026, bringing the market’s cumulative growth rate for the year below 22%.
As we reported in August, July had been the fifth straight month above the $300 million threshold, when iGaming gross receipts reached $302.8 million.
August’s result left Michigan 21.4% ahead of its pace a year earlier, an increase of $424.5 million. The month generated $61.2 million in state tax revenue and a further $21.9 million for city and local jurisdictions, according to Sports Betting Dime, which drew on Michigan Gaming Control Board revenue data.
The Gaming Control Board says regulated internet gaming and sports betting began in Michigan on Jan. 22, 2021. Its revenue information page states that the state wagering tax paid by casinos, equal to 8.1% of adjusted gross receipts, is deposited in the School Aid Fund for statewide K-12 classroom education. Detroit’s city wagering tax, set at 10.9% of casino AGR, may support purposes including public safety, anti-gang and youth-development programmes.
Michigan’s August growth rate nevertheless exceeded those reported in two other large iGaming markets. Pennsylvania posted $328.6 million in online casino revenue, its second-largest month on record, but year-over-year growth was 12.7%. New Jersey generated $259.3 million and recorded 4.4% growth, its lowest monthly growth rate ever, according to the same report.
Michigan had 15 operators offering internet gaming, while 13 offered internet sports betting, the Gaming Control Board said in its Sept. 8 executive director report.
