Michigan surpasses $340 million in gambling revenue in June 2026
Michigan’s regulated online gambling market once again recorded one of the strongest performances in the United States in June 2026. Commercial and tribal operators generated a combined $341.3 million in gross revenue from iGaming and online sports betting, strengthening the state’s position as one of the leading regulated gambling markets in the country. Despite the strong performance, the figures also highlight a clear trend: while online casinos continued to grow, sports betting lost momentum in June due to a reduced number of major sporting events on the US calendar.
The figures were released by the Michigan Gaming Control Board (MGCB) and show that combined revenue declined by 10.8 per cent compared with May, when the market reached $382.5 million. Even so, the result keeps Michigan among the highest grossing gambling jurisdictions in the country, driven primarily by the strength of iGaming.
Online casinos account for nearly 90 per cent of revenue
The report’s main feature is the performance of iGaming. In June, online casinos generated $301.2 million in gross revenue, representing approximately 88 per cent of the state’s total gambling revenue. Based on adjusted gross revenue (AGR), which excludes promotional credits and bonuses granted to players, the segment reached $289.2 million, representing a 28 per cent increase compared with June 2025.
The result shows a trend that has emerged over recent years. Unlike sports betting, whose revenue fluctuates with the calendar of major sporting competitions, online casinos generate more consistent demand throughout the year. Games such as online slots, roulette, blackjack and live dealer games continue to attract players regardless of the sports season, making iGaming the primary source of revenue for both operators and the state government.
This stability also explains why Michigan has recorded consecutive months with combined revenue exceeding $300 million throughout 2026, even during traditionally weaker periods for sports betting.
Sports betting slows during the off season
While online casinos maintained their growth, sports betting delivered a more modest performance. Gross revenue from the segment totalled $40.1 million, while adjusted gross revenue reached $20.2 million, representing a year on year decline of 33.9 per cent. Total betting handle also decreased, falling from $457.6 million in May to $366.1 million in June, a decline of 20 per cent.
The slowdown did not come as a surprise to the market. June is typically one of the weakest months for sportsbooks in the United States, as it coincides with the end of the NBA and NHL seasons while the NFL remains in its off season. With fewer high profile sporting events available, betting activity naturally declines.
This seasonal pattern contrasts with months such as September, October and January, when the sporting calendar includes the NFL, college football, the NBA, the NHL and playoff competitions simultaneously, notably increasing betting volumes.
Tax revenue remains strong
Despite the monthly decline in total revenue, the market continued to generate substantial tax income for the state. In June, operators paid $62.3 million in taxes and fees to the state of Michigan. Of that amount, $60.8 million came from iGaming, while online sports betting contributed $1.5 million.
In addition to state tax revenue, Detroit’s three casinos paid approximately $14 million in municipal taxes and public service fees. Tribal operators also reported around $8.4 million in payments to their respective tribal governments.
The figures demonstrate how the regulated model generates revenue across multiple levels of government, benefiting the state, municipalities and tribal communities.
Mature market continues to grow
Michigan regulated online sports betting and iGaming in 2021. The state currently has 15 licensed online casino operators and 13 licensed online sports betting operators. Strong competition between major national brands and tribal casino operators has helped create a thriving market characterised by significant investment in technology, loyalty programmes and promotional offers.
Another important factor is that, unlike many US states where only sports betting is legal, Michigan permits both online sportsbooks and online casinos. This combination has proven to be financially advantageous.
While states that rely exclusively on sports betting often see revenue fluctuate significantly with the sports calendar, Michigan has maintained strong results throughout most of the year thanks to the consistent performance of iGaming.
The June figures reinforce a trend seen across several US gambling markets: iGaming is growing faster than sports betting. Although major events such as the NFL season and the 2026 FIFA World Cup continue to drive sportsbook activity during specific periods, the recurring revenue generated by online casinos has become increasingly important for both operators and state governments.
