Michigan officials are widening their fight against illegal online gambling, taking action against 45 offshore sites accused of targeting players in the state without approval.

The Michigan Gaming Control Board said Tuesday (April 7) that it issued cease-and-desist orders to the operators after a months-long investigation. Regulators found the sites were offering casino-style games or sports betting to Michigan users despite lacking the required state licenses.

This is thought to be one of the agency’s most expansive enforcement efforts so far. It also builds on a series of recent crackdowns, including earlier actions against twelve offshore operators and another case involving eight unlicensed online casinos.

“The scope of this action sends a clear message: Michigan will not tolerate illegal operators targeting our residents or undermining the lawful businesses that have invested in complying with state law,” said MGCB Executive Director Henry Williams. 

“Our investigators work with unwavering focus to identify, document, and act against every unlicensed site that puts Michigan players at risk. This is an ongoing effort, and we will continue to take action against illegal gambling operators.”

Among the companies flagged in the latest sweep are well-known offshore brands such as BetOnline.ag, SportsBetting.ag, and Americas Card Room, along with a range of casino sites operating under different domain names. State officials say each of them accepted wagers or provided gambling services without authorization.
