Gross gaming revenue from the Michigan iGaming sector rose by 33.9% year-on-year in April, according to figures released by the Michigan Gaming Control Board.

The monthly report showed that the legal Michigan online casino market generated $233.1 million in adjusted gross receipts (AGR) during the month, a rise from last year’s April figure of $174.86 million but a 5.3% decline from the March AGR figure for iGaming of $246.08 million.

The $233.1 million AGR from iGaming represents a little under 90% of the total revenue across the sector. Sports betting contributed $26.8 million in AGR in April, showing a 3.6% decrease on the year-on-year figure but a dramatic 83.4% rise on March’s sports betting AGR.

Tax contributions

The Michigan gambling industry includes 15 commercial and tribal operators, all of which are permitted to offer iGaming and Michigan sports betting. Currently, all 15 casino operators provide iGaming, but only 12 are licensed to take sports betting wagers.

In total, the state’s licensed gambling operators contributed $49.6 million in state taxation and other payments during April, the vast majority of that contribution coming from iGaming. The iGaming segment generated $48.2 million in fees and taxes, while sports betting contributed $1.4 million.

The three commercial casinos located in Detroit also contributed $13.1 million to the city coffers in April, $12.6 million of which came from iGaming in the form of wagering taxes and municipal services fees. Tribal operators also paid $5.6 million in fees to their governing bodies.

Illegal gambling crackdown

April also saw the state regulator continue its efforts to clamp down on illegal gambling sites, issuing cease-and-desist orders to two sports betting sites.

The Michigan Gaming Control Board (MGCB) issued the notifications to SportsBetting.ag and BetOnline.ag, which are both based in Panama and do not hold licenses to operate in Michigan.

According to the MGCB, the gambling operations of these sites are illegal and in violation of the state’s Gaming Control and Revenue Act, Penal Code, and Lawful Internet Gaming Act. The Board found that SportsBetting.ag was offering everything from sports betting to virtual casino games, while BetOnline.ag was providing a similar range of gambling products, allowing visitors to fund their gambling through cryptocurrency, wire transfer, or credit card. Both sites have been given 14 days to end their activities in Michigan or face further legal action.

“The Michigan Gaming Control Board is committed to enforcing Michigan’s gaming laws and protecting consumers from illegal gambling. We encourage residents to only engage with licensed and regulated online platforms for a safe and fair gaming experience,” said the Executive Director of the MGCB, Henry Williams.

The MCGB is one of the most active regulators in the US in promoting healthy and legal gambling, cracking down on illegal operators, and frequently posting reminders to gamblers to play responsibly ahead of significant sports events, like its March Madness notification.
