Polymarket US has agreed to stop offering new sports-related event contracts to Michigan customers and close remaining open positions by the end of Nov. 25, under an agreement approved by the U.S. District Court for the Western District of Michigan.
QCX LLC, which does business as Polymarket US, will close any contracts held by Michigan residents that customers have not voluntarily exited by the deadline. The Michigan Gaming Control Board said the agreement covers sports-related contracts, while the company’s appeal remains pending at the U.S. Court of Appeals for the Sixth Circuit.
Michigan agreed to refrain from enforcement action as long as Polymarket complies with the arrangement, according to The Detroit News. The agreement follows a Sept. 10 warning from the Michigan attorney general’s office that it would pursue legal action unless the company stopped offering the contracts.
Polymarket sued Michigan state officials in federal court in March, seeking to block enforcement of state gaming laws. The court denied the company’s request for a temporary restraining order that month and rejected its preliminary-injunction motion in June, before the company appealed to the Sixth Circuit.
The deal makes Polymarket the fourth operator whose sports-event contracts Michigan has halted through an agreement or court order, after KalshiEX, Robinhood Derivatives and Coinbase Financial Markets. As reported earlier this month, Coinbase agreed to stop new Michigan sports contracts and close its remaining positions by Oct. 10.
Michigan obtained a preliminary injunction against Kalshi in September requiring the company to use third-party geolocation to prevent Michigan residents from trading sports-event contracts while the case proceeds. Judge Rosemarie Aquilina had said Kalshi’s alleged noncompliance gave it a “massive and unfair advantage” over regulated online sportsbooks and casinos.
MGCB Executive Director Henry Williams said operators offering sports wagering to Michigan residents need a Michigan license. Attorney General Dana Nessel said the Polymarket agreement continued the state’s effort to enforce its gaming laws against national sports-betting operators.
