Michigan iGaming holds above $300 million in September as annual growth edges up to 18.4%

Michigan's online casino and poker operators reported $300.2 million in September iGaming gross receipts, a seventh straight month above $300 million, even as adjusted receipts slipped 0.9% from August. Year-on-year growth of 18.4% came in slightly above August's 17.6%, after annual rates of 25.4% in February and 25.6% in March, a reading consistent with a slowdown that has stopped deepening for now.

• Michigan's iGaming gross receipts were $300.2 million in September, the seventh consecutive month above $300 million.
• Adjusted iGaming receipts fell 0.9% from August to $288.15 million but were 18.4% higher than in September 2025.
• Operators paid the state $62.4 million in September taxes and payments, $60.6 million of it from iGaming.
• All 15 authorized commercial and tribal operators offered iGaming in September, while 13 offered online sports betting.

Michigan’s online casino and poker market cleared $300 million in monthly gross receipts again in September. Operators reported $300.2 million in iGaming gross receipts, the seventh straight month above that mark, the Michigan Gaming Control Board said on Oct. 22. Adjusted gross receipts, the figure after deductions, came in at $288.15 million, down 0.9% from August but up 18.4% from a year earlier.

The month-on-month dip is small. The annual figure is the more telling one. August’s adjusted receipts of $290.8 million were 17.6% ahead of August 2025, so September’s 18.4% marks a slight uptick in the year-on-year pace rather than a further decline.

Seven months above $300 million since February’s $273.1 million

The run began after February, when iGaming gross receipts were $273.1 million. March then set a high of $322.1 million, beating the previous peak of $315.8 million from December 2025, with adjusted receipts of $309.1 million that month. Since then the gross figure has stayed above $300 million every month, though it has drifted down toward the threshold: $303.0 million in August and $300.2 million in September.

Adjusted receipts tell a similar story of a plateau. July’s total was $290.65 million, August added 0.1% to reach $290.8 million, and September gave back 0.9%. At $288.15 million, September’s adjusted figure sits below both of the two preceding months, which were separated from each other by just 0.1%.

For context, Michigan finished 2025 with $3.09 billion in iGaming gross receipts and $2.90 billion in adjusted receipts. Through July 31 of this year, adjusted receipts had already reached $2 billion.

Annual growth at 18.4% after sliding from 25.6% in March

The year-on-year rate is where the cooling shows. February’s adjusted receipts were 25.4% above the prior February, and March’s were up 25.6%. By July the rate was 23.6%. August then fell to 17.6%.

September’s 18.4% breaks that downward run, at least for one month. One reading does not establish a trend, and the board does not attribute the change to any cause. The figures are consistent with growth settling in the high teens after the mid-20s pace of early 2026, rather than continuing to fall month after month.

That matters beyond Michigan. The American Gaming Association reported that US iGaming revenue grew 27.6% to a record $10.73 billion in 2025, with Michigan, New Jersey and Pennsylvania accounting for nearly 90% of the total. Growth in high-teens percentages is slower than the national pace of 2025, but it comes on a larger base.

Sportsbook handle of $544.8 million lifts combined receipts 5.4%

While iGaming dipped, the sports side moved sharply the other way. Sportsbook handle reached $544.8 million in September, 64.9% higher than in August, and online sports betting gross receipts were $55.5 million. Combined iGaming and online sports betting gross receipts totaled $355.7 million, up 5.4% from August.

The split shows how heavily the state’s online market leans on casino and poker. Of the combined $355.7 million, iGaming supplied $300.2 million.

The tax picture follows the same pattern. Operators paid the State of Michigan $62.4 million in taxes and payments for September, of which $60.6 million came from iGaming, compared with $61.2 million in iGaming taxes and fees in August. Tribal operators paid a further $8.3 million to their governing bodies.

Legal Sports Report’s tracker, updated Sept. 17, puts Michigan’s lifetime online casino and poker revenue at $12,255,126,886, with $3,176,464,122 in taxes.

Poker inside the iGaming total after the PokerStars on FanDuel switch

The board does not report poker separately from casino, so poker’s share of the $300.2 million cannot be isolated. The month still captures a reshaped poker market. PokerStars Exclusively on FanDuel went live on April 1, replacing the old PokerStars US software in Michigan, New Jersey and Pennsylvania with an iPoker-powered platform and adding Pennsylvania to the existing Michigan-New Jersey player pool, according to PokerFuse.

That move followed a plan published March 3 that shifted PokerStars players in the three states and in Ontario onto FanDuel accounts with one shared wallet for poker and FanDuel’s other products. The licensing side changed too. After PokerStars exited Michigan, its role with the Little Traverse Bay Bands of Odawa Indians passed to bet365: on April 17 the board cleared that operator, under the entity Hillside Michigan LLC, to supply the tribe’s online casino and sports wagering.

The operator count held steady through those changes. As of September, 15 commercial and tribal operators were authorized in Michigan, and all 15 offered iGaming while 13 offered online sports betting.

Every month of 2026 iGaming results will now be measured against 2025’s full-year adjusted total of $2.90 billion, a mark the state had already passed two-thirds of by July 31.
