Michigan iGaming Revenue Climbs as Online Sports Betting Slows

LANSING, Mich. – Michigan online gambling operators reported $382.5 million in combined iGaming and online sports betting gross receipts in May. The figures show online casinos continuing to drive Michigan’s digital gambling market, while sports betting revenue remained weaker on a year-over-year basis. Combined gross receipts were up 3.1% from April. Michigan iGaming gross receipts reached $305.8 million in May, far ahead of the $76.7 million reported from online sports betting. The split keeps online casino revenue at the center of Michigan’s regulated internet gambling market.

Online Casinos Lead Michigan’s May Total

Figures in the Michigan Gaming Control Board’s May revenue report show combined adjusted gross receipts reached $316.72 million in May. including $293.45 million from iGaming and $23.27 million from online sports betting. Compared with April, iGaming adjusted gross receipts increased 0.8%, while online sports betting adjusted gross receipts declined 4.9%. The year-over-year gap was much wider, with iGaming adjusted gross receipts up 24.2% and online sports betting adjusted gross receipts down 34.6%. The sports betting handle reached $457.6 million in May, a 0.7% decrease from April. That means the betting market remained active by volume, even as adjusted revenue moved lower.

State and Detroit Payments Reach Millions

Operators submitted $64.2 million in taxes and payments to the State of Michigan in May. iGaming accounted for $61.5 million of that total, while online sports betting contributed $2.7 million. Detroit’s three casinos reported $14.6 million in wagering taxes and municipal services fees paid to the city. That included $13.8 million from iGaming and $839,168 from online sports betting. Tribal operators reported $8.4 million in payments to governing bodies for the month. Michigan’s online gambling tax structure directs money through several funds, including internet gaming and sports betting funds, with portions also flowing to Detroit, local governing bodies and state-designated funds.

Michigan Market Remains Casino-Led

As of May 2026, Michigan had 15 commercial and tribal operators authorized to offer iGaming and/or online sports betting. All 15 offer iGaming, while 13 offer online sports betting. The May figures reinforce a pattern seen across mature online gambling states with legal online casinos. Casino gaming is producing the larger and steadier revenue stream, while sports betting remains more sensitive to margins, seasonality and monthly results. For Michigan, the next monthly reports will show whether online casino growth continues to offset softer sports betting revenue. For operators, May’s results point to the same market reality: iGaming remains the state’s main online revenue engine.
