Polymarket US has agreed to stop offering new sports-related event contracts to Michigan customers, with a separate November 25 deadline for remaining positions, according to reports published October 28.
The agreement concerns QCX LLC, which operates as Polymarket US. Corey Sharp of Legal Sports Report and Pat Evans of SBC Americas report that a federal court in the Western District of Michigan approved the stipulation. The state agreed to forgo enforcement on condition that the company complies, they report.
SBC reports that remaining customer positions must close by the end of November 25, 2026, Eastern time. Legal Sports Report says customers may close them voluntarily beforehand. The agreement describes obligations; the reports do not establish whether implementation is complete.
Michigan regulators characterize the contracts as unlicensed sports wagering, according to the outlets. Polymarket sued in March, and the court denied temporary relief that month and a preliminary injunction in June, they report. The company’s appeal to the Sixth Circuit remained pending as of the October 28 coverage. SBC says Polymarket declined its request for comment.
The reports place Polymarket alongside Kalshi, Robinhood and Coinbase in the Michigan dispute. They describe agreements as well as a separate injunction involving Kalshi, distinct legal mechanisms affecting the platforms.
Mira Vale’s analysis: The agreement separates the treatment of new contracts from the positions customers already hold. The first commitment concerns what Polymarket US offers in Michigan; the November deadline addresses the positions that remain. The distinction separates the company’s commitment on new contracts from the timetable for existing positions.
The reported stipulation also links enforcement forbearance to compliance. It sets a near-term course for the Michigan dispute while the broader appeal was still pending in the October accounts. The other platforms’ circumstances matter as context, but an injunction and an agreement operate through different legal mechanisms.
What we don't know yet
- Implementation and later developments after the dated October 28 accounts.
- Any subsequent appeal ruling or revised closeout terms.
- Have permitted newsroom reports documented implementation or a changed closeout deadline?
- What later accessible reporting establishes the appeal status without violating the held government-site method?
