Michigan’s commercial and tribal gaming operators generated a combined $341.3 million in gross receipts from iGaming and online sports betting during June, according to figures released by the Michigan Gaming Control Board (MGCB). While the total represented a 10.8% decline from May, internet casino gaming continued to post strong annual growth and remained the state’s primary online gambling revenue source.
The figures reflected continued player activity across Michigan’s regulated market, with iGaming producing the majority of monthly earnings and contributing most of the tax payments collected during the period.
The latest results come as the MGCB continues broader regulatory activity, including legal action against prediction market operator Kalshi over sports-event contracts offered in the state.
iGaming Remains Main Revenue Driver
June iGaming gross receipts reached $301.2 million, while online sports betting contributed $40.1 million, producing combined gross receipts of $341.3 million.
Adjusted gross receipts (AGR) totaled $309.36 million for the month, consisting of $289.21 million from iGaming and $20.15 million from online sports betting.
Compared with May, iGaming AGR declined 1.5%, while online sports betting AGR fell 13.4%. The year-over-year comparison showed different trends. iGaming AGR increased 28.0%, whereas online sports betting AGR decreased 33.9%.
Sports betting activity also slowed during June. Total online wagering handle reached $366.1 million, down 20.0% from the previous month.
The MGCB reported that operators paid $62.3 million in taxes and fees to the State of Michigan during June. Of that amount, iGaming accounted for $60.8 million, while online sports betting generated $1.5 million.
Detroit’s three commercial casinos also paid $13.96 million in wagering taxes and municipal service fees to the city, including $13.5 million from iGaming and $460,753 from online sports betting. Tribal operators reported an additional $8.4 million in payments to governing bodies.
As of June, Michigan had authorized 15 commercial and tribal operators to provide online gaming services. All 15 offered iGaming, while 13 also operated online sportsbooks.
Enforcement Action Against Kalshi Continues
The June revenue report follows recent regulatory action by the MGCB against prediction market operator Kalshi.
Michigan regulators secured a temporary court order preventing Kalshi from offering sports-event contracts within the state. The MGCB argues that the company is providing unlicensed sports wagering while presenting the products as financial contracts. Kalshi has maintained that its prediction markets operate as federally regulated investment products rather than gambling.
The regulator also withdrew from the National Council on Problem Gambling after the organization partnered with Kalshi, reinforcing its position on the dispute.
The developments form part of a broader legal battle between prediction market operators and state gaming regulators across the United States. Michigan has taken a firm stance that sports-event contracts offered through prediction market platforms fall within state gambling laws and should be subject to the same regulatory standards as licensed sportsbooks.
The state’s latest financial results indicate that iGaming continues to provide the largest share of regulated online gambling revenue even as sports betting activity softened during June.
