Michigan’s online casinos generated $300.2 million in gross receipts in September, keeping the market above $300 million for a seventh consecutive month. The result was 0.9% below August’s $303 million, but 15.9% higher than in September 2025.
The 15 online casino operators produced $288.2 million in adjusted gross receipts, the taxable measure, according to Casino Reports. That figure was also down 0.9% from August, although it was about 2.4% higher on a per-day basis because September had one fewer day. Adjusted gross receipts rose 18.4% year on year.
As we reported in September, Michigan’s August iGaming gross receipts were $303 million, continuing a run in which casino revenue has settled close to that level. September was the sixth straight month in a $300 million-to-$306 million band, a pattern Casino Reports characterized as evidence of a relatively mature iGaming market.
The state collected $60.6 million in taxes from September online casino activity, extending its run of monthly iGaming tax collections above $60 million to seven months. City and local jurisdictions received a further $21.8 million.
September’s combined online casino and sports-betting gross receipts reached $355.7 million, up 5.4% from August, even as casino receipts edged lower. Year-to-date iGaming gross receipts totaled $2.71 billion through September, a 20.4% increase on the first nine months of 2025.
FanDuel remained the largest online casino operator by adjusted gross receipts, with $71.3 million, followed by BetMGM at $60.8 million and DraftKings at just under $43 million. BetRivers, Fanatics and Hard Rock followed, ahead of Caesars, which recorded $14.9 million after a 10.7% monthly decline.
Michigan’s 2026 monthly online casino average stood at $301.1 million at the time of the report, implying annual gross receipts of about $3.61 billion if the pace holds. That would exceed the $3.1 billion in iGaming gross receipts reported for all of 2025, when December set the then-record monthly high of $315.8 million.
