KEY TAKEAWAYS
Online sportsbooks in Michigan took $544.8 million in wagers in September 2026, a 64.9% rise from August, according to figures the Michigan Gaming Control Board published on October 22, 2026. The same report put online sports betting adjusted gross receipts at $24.89 million, which is 2.9% above the prior month and 88.2% above September 2025. Taken together with internet casino gaming, commercial and tribal operators reported $355.7 million in gross receipts for the month.
Operators remitted $62.4 million to Michigan in taxes and other payments, and $1.8 million of that came from sports betting. The regulator’s release does not say what drove the month-over-month increase in handle, and its figures cover online play only. Retail sportsbooks at the three Detroit casinos are tracked separately in the board’s reports.
What Michigan’s Regulator Reported
The board’s October 22 release covers both of Michigan’s online verticals, internet casino gaming and online sports betting, and combines results from commercial and tribal operators. For sports betting specifically, it gives four headline measures: gross receipts, adjusted gross receipts (AGR), handle and taxes. Each is reported for September 2026 with a comparison to August or to a year earlier.
Gross receipts from online sports betting reached $55.5 million in September. AGR, a lower figure, came in at $24.89 million. Handle, the total amount wagered, was $544.8 million. The release attributes a 64.9% increase in handle to the comparison with August 2026, and it describes the AGR changes as a 2.9% rise from August and an 88.2% rise year over year.
The report also covers the market’s structure. In September 2026, fifteen operators, a mix of commercial and tribal, hold authorization to run iGaming, online sports betting or both in Michigan. Every one of them offers iGaming, and 13 also offer online sports betting. Operator-level results are published on the board’s website and are not reproduced in the release itself.
The board publishes these measures for each calendar month, which is what makes the month-to-month comparisons in the release possible.
The Key Figures for September 2026
The table collects the sports betting figures from the release. Every entry comes from the Michigan Gaming Control Board’s October 22, 2026 report on September 2026 results.
| Measure | September 2026 | Change reported |
|---|---|---|
| Online sports betting handle | $544.8 million | +64.9% from August 2026 |
| Online sports betting gross receipts | $55.5 million | Not stated in release |
| Online sports betting adjusted gross receipts | $24.89 million | +2.9% from August; +88.2% from September 2025 |
| Online sports betting taxes and fees (state) | $1.8 million | Not stated in release |
| Online sports betting taxes and fees (City of Detroit) | $548,519 | Not stated in release |
What the ratios show
Some useful ratios can be calculated from the published figures, with the caveat that these are GamingNewsNow’s own calculations and not numbers the regulator reported. Dividing gross receipts by handle gives about 10.2%, and dividing AGR by handle gives about 4.6%. The release does not itemize what separates the two measures.
The percentage changes also let a reader work backward. A 64.9% rise to $544.8 million implies an August handle of roughly $330.4 million, and a 2.9% rise to $24.89 million implies August AGR of about $24.19 million. An 88.2% year-over-year rise implies September 2025 AGR of about $13.23 million. These implied values are approximations because the release rounds its percentages.
Sports betting versus iGaming
Internet casino gaming remains the larger vertical in every measure the release reports. iGaming gross receipts were $300.2 million against $55.5 million for sports betting, and iGaming AGR was $288.15 million against $24.89 million. By calculation, sports betting made up about 7.95% of combined AGR of $313.04 million.
Where Michigan Stood Before September
The September figures follow a summer in which Michigan’s sportsbook revenue moved sharply. In the board’s September 8, 2026 executive director report, July online sports betting adjusted gross receipts were $30.77 million, up 52.7% from June and up 28.8% from July 2025. Through the end of July, aggregate online sports betting AGR for 2026 totaled $193.7 million.
Set against those numbers, September’s $24.89 million AGR is lower than July’s figure but higher than the roughly $24.19 million implied for August. In other words, revenue dipped from July to August and recovered slightly in September, while handle rose by nearly two-thirds between August and September, according to the percentages the board reported.
The executive director report also described the combined online market for July: operators reported $346.13 million in gross receipts, which was 1.4% more than June, and $321.42 million in AGR. September’s combined gross receipts of $355.7 million are therefore higher than July’s by roughly $9.6 million, a calculation that treats the two reports’ definitions as comparable.
Retail betting remains small by comparison. In the same July report, the three Detroit casinos reported retail sports betting handle of $5,882,832, which is small next to the $544.8 million that online operators handled in September, although the two figures cover different months.
Why the Report Matters for the Market
The tax lines show how differently the two verticals contribute. Online sports betting generated $1.8 million in state taxes and fees in September, while iGaming generated $60.6 million. By calculation, iGaming accounted for about 97% of the $62.4 million operators remitted to the state, and its taxes and fees equaled roughly 21% of iGaming AGR against about 7% for sports betting.
Detroit’s share follows the same pattern. The Detroit casinos paid the city $14.0 million in wagering taxes plus municipal fees, of which $13.5 million came from iGaming and $548,519 from online sports betting. Tribal operators’ payments to their governing bodies came to $8.3 million; the release does not split that figure by vertical.
For bettors, the practical relevance is the scale of the regulated market they use. Thirteen authorized operators offer online sports betting, and the handle figure indicates the volume moving through them in a single month. For operators and suppliers, the year-over-year AGR gain of 88.2% shows the segment’s adjusted gross receipts have grown considerably, from roughly $13.2 million a year earlier by calculation, according to the figures the board reported.
What the Figures Do and Do Not Show
The headline 64.9% increase is a month-over-month figure, not a year-over-year one. The release gives a year-over-year comparison for AGR, at 88.2%, but it does not provide one for handle. Readers should not interpret the handle increase as growth against September 2025.
The release also says nothing about hold, the share of wagers that sportsbooks keep. The ratios calculated above depend on how Michigan defines gross receipts and AGR, and they are not hold figures in the sense that other regulators use the word. Comparing them directly with another state’s published hold percentage would be misleading.
Finally, the release does not explain the changes it reports. The board did not attribute these September results to any cause, and this report does not either. Percentages are rounded, and the board’s operator-level tables are the place to look for detail.
How Michigan Compares With Other States’ Reports
Other regulators published September 2026 sports wagering data in the same weeks. The comparison below uses each regulator’s own labels. The definitions differ: Michigan’s figure is online only, while Maryland and Iowa include retail wagering, so the handle totals are not strictly comparable.
| State | September 2026 handle | Regulator’s revenue measure |
|---|---|---|
| Michigan (online only) | $544.8 million | AGR: $24.89 million |
| Maryland (retail and mobile) | $652,200,900 | Taxable win: $45,921,614 |
| Iowa (retail and internet) | $290,239,048 | Net receipts: $23,745,911 |
| Vermont | $19,758,552 | Adjusted gross revenue: $1,710,695 |
Michigan’s online handle equals about 84% of Maryland’s combined handle, by calculation, even though Maryland’s total includes $11,049,602 in retail wagers. Iowa’s handle was roughly $276.1 million of internet wagering and $14.1 million of retail, and Maryland’s mobile handle was $641,151,298. GamingNewsNow covered Maryland’s report in detail in Maryland September Sports Betting Hold Falls to 9.0%.
What to Watch Next
The next data point is the board’s report on October 2026 results. The release does not give a publication date for it. Because the board reports monthly, readers can check whether handle holds near September’s level and whether AGR continues to track above the roughly $24 million range of August and September.
Operator-level results, which show how the 13 sports betting operators split the market, are available on the board’s website and are the next layer of detail for anyone following specific brands.
