Michigan’s online casino market set a new monthly revenue record in August 2025, with the online casino industry’s gross winnings reaching $263.27 million.
While the Michigan Gaming Control Board’s release framed results as combined online casino and online sports betting totals, Gambling Harm can confirm the online casino gambling figure itself is a state record.
August 2025’s total edged past March 2025’s previous high of $260.52 million.
Let’s examine the state of the Michigan online casino market.
Michigan Online Casino Market – 2025

Overall, Michigan online gambling operators reported $312.54 million in combined gross receipts from online gambling in August.
Within the total, online casinos won $263.27 million, and sportsbooks won $49.27 million.
Do Online Casinos Benefit Michigan?
The record online gambling haul translated into public revenue. However, it’s unlikely the tax revenue offsets the widespread harm done to Michiganders.
Michigan online gambling operators paid $53.7 million in state taxes and payments in August 2025 — $51.6 million from online casinos and $2.1 million from internet sports betting.
That might sound like significant tax revenue. However, studies show online gambling has negative economic effects. Furthermore, few online gamblers win money in the long run.
Critics have called online gambling a regressive tax on economically vulnerable residents.
Calls to Michigan’s 24/7 problem gambling helpline more than tripled since online casino/sports betting launched — rising from 1,341 (FY 2018-19) to 4,543 (FY 2023-24), according to state-released figures reported by Bridge Michigan.
MI Online Casino Market Grows
Michigan’s online gambling market outpaced expectations in 2025, and the August record underscored the state’s position among the nation’s largest online casino jurisdictions.
In fact, Michigan is the largest online casino gambling market in the nation.
Here’s a look at Michigan versus Pennsylvania and New Jersey online casino markets.

| Feb | 207.6 | 207.8 | 222.5 |
| Mar | 238.2 | 243.9 | 260.5 |

How Many Online Casinos Are There in MI?
Michigan law authorizes up to 15 licensed online casino operators.
The active count fluctuates slightly (roughly 13–15 in 2025) as brands launch, rebrand, or exit the market.
Every online casino must partner with a Detroit commercial or tribal casino. For the exact number, see the Michigan Gaming Control Board’s authorized list.
The largest online casinos in Michigan in terms of revenue include FanDuel, DraftKings, BetMGM, Caesars, and BetRivers.
Michigan the Largest Online Casino Market in the U.S.
Michigan is the largest online-casino market in the U.S., regularly outpacing New Jersey and Pennsylvania on monthly online gambling revenue. Other U.S. online casino states include Delaware, Connecticut, and West Virginia.
The Wolverine State benefits from not bordering any online casino states. Ohio and Indiana do not have online casinos, but their respective legislatures have considered bills.
In August 2025, Michigan operators generated $263.27 million in gross online casino receipts — a new state record — versus New Jersey’s $248.4 million and Pennsylvania’s $231.2 million during the same month.
Michigan’s market size reflects broad operator participation, deep crossover with Detroit and tribal casinos, and a mature mobile user base.
Taxes and payments from online casino gambling exceed $50 million per month.
However, each month, the harm mounts for Michiganders.
In the Garden State, which trails Michigan in online gambling but is still a massive market, regulators have looked to modernize New Jersey’s gambling rules. Michigan might eventually do the same to better address addiction.
