Michigan’s commercial and tribal online operators reported $355.7 million in combined internet gaming and online sports betting gross receipts in September, up 5.4% from August, according to the Michigan Gaming Control Board.
Online casinos again supplied most of the total, while sports betting handle surged as football season began. The board released the figures on October 22.
iGaming gross receipts totaled $300.2 million, and online sports betting gross receipts reached $55.5 million. Combined adjusted gross receipts, which account for permitted deductions, came to $313.04 million. Combined gross receipts were $346.13 million in July and $337.6 million in August.
Of the September adjusted total, iGaming accounted for $288.15 million and sports betting for $24.89 million. Fifteen commercial and tribal operators are authorized in the state, and 13 of them offer sports betting.
Sportsbooks took $544.8 million in wagers, up 64.9% from August’s $330.5 million. Adjusted sports betting receipts rose just 2.9% from August, while iGaming adjusted receipts slipped 0.9%.
That gap shows in hold, the share of wagers sportsbooks keep. Based on the board’s figures, adjusted sports betting receipts equaled roughly 4.6% of handle in September, compared with about 7.3% in August. These are calculated figures, not ones the board published.
Compared with September 2025, adjusted receipts were up 18.4% for iGaming and 88.2% for sports betting, according to the board’s year-over-year comparison.
Operators sent $62.4 million in taxes and payments to the state in September. iGaming accounted for $60.6 million of that, about 97%, with sports betting contributing $1.8 million.
The three Detroit casinos paid $14.0 million in wagering taxes and municipal services fees to the City of Detroit. iGaming made up $13.5 million of that total, and sports betting added $548,519. Tribal operators reported $8.3 million in payments to their governing bodies.
The difference in tax contributions reflects the size of each market. Online casino games generated more than 11 times the adjusted receipts of sportsbooks in September, and sports betting produced a small share of state payments.
The report arrives two weeks after the board announced it had sent cease-and-desist letters to 33 offshore operators. The board said they were illegally offering online casino games, sweepstakes-style games or sports betting to Michigan residents. Its announcement did not identify which recipients operate sweepstakes games.
Online casino and sports betting revenue is a measure of the regulated market only. Activity with unlicensed sites does not appear in the board’s figures or in state tax collections.
Michigan’s September figures also come as football season lifts sports betting volumes in many states. The board’s monthly releases do not break out handle or revenue by sport.
October results will show whether handle holds near September’s level and whether sportsbooks hold more of it. iGaming has been the steadier contributor, and its monthly gross receipts have stayed above $300 million in each of the last two reports. The board typically publishes monthly internet gaming figures in the second half of the following month.
