Michigan regulators have given the green light for online gambling and online sports betting to start at noon Friday.

The Michigan Gaming Control Board announced Tuesday that it approved the first nine casinos and their online platform partners to launch at that time, with additional approvals expected in coming days.

The Legislature and Gov. Gretchen Whitmer legalized internet gambling and sports betting in December 2019, and regulators spent all of last year devising rules and ways to monitor and license the new platforms.

The minimum age for online gambling and sports betting is 21. Those taking part in sports betting do not need to be Michigan residents, but must be situated within the state’s borders when placing bets via smartphone app or computer. Those from Ohio, where online sports betting isn’t legal, could therefore use Michigan’s new betting apps if they do so in Michigan.
