Michigan’s regulated online gambling market ended 2025 with its strongest performance since launch, driven by sustained growth in internet casino gaming and another solid year for online sports wagering. Data released by the Michigan Gaming Control Board shows combined commercial and tribal operators generated $3.8 billion in total gross receipts for the year, reflecting a 29.5% increase compared with 2024.
The annual total included $3.1 billion from iGaming activity and $671.3 million from internet sports betting. After accounting for promotional spending, adjusted gross receipts across both verticals reached $3.3 billion, representing year-over-year growth of 39.5%. The state also reported $5.4 billion in betting handle for the year, indicating steady wagering volume even as revenue efficiency improved.
December capped the year with a new monthly high. Combined iGaming and online sports betting gross receipts totaled $399.8 million, a 19.1% increase from November and more than 50% higher than December 2024. The final month highlighted the expanding role of online casinos in Michigan’s market, even as sports betting activity eased from prior levels.
December Performance Sets New Benchmarks
Online casino gaming produced $315.8 million in gross receipts during December, marking the highest single-month total since Michigan launched regulated iGaming. The figure surpassed the previous record of $278.5 million set in October. Internet sports betting gross receipts reached $84.0 million for the month, down slightly from November’s $87.3 million but still among the strongest results of the year.
Adjusted gross receipts for December totaled $357.87 million, with iGaming accounting for $296.74 million and online sports betting contributing $61.13 million. Compared with November, adjusted iGaming revenue increased 27.2% while adjusted sports betting revenue declined 5.6%.

Annual Revenue Growth and Market Leaders
For the full year, iGaming adjusted gross receipts reached $2.9 billion, while adjusted sports betting revenue totaled $435.9 million.

Taxes, Detroit Casinos, and Market Outlook
Operators paid $624.6 million in taxes and payments to the State of Michigan during 2025, including $597.5 million from iGaming and $27.1 million from online sports betting. Tribal operators reported $71.9 million in payments to governing bodies for the year. Detroit’s three commercial casinos contributed $161.4 million in wagering taxes and municipal service fees, with iGaming responsible for the majority of that total.
