According to G3Newswire, the Michigan Gaming Control Board said QCX LLC, doing business as Polymarket US, has agreed to stop making new sports-related event contracts available to customers in Michigan.

The agreement also covers existing exposure: remaining open positions must be closed out by the end of the day Eastern time on November 25, 2026.

Michigan’s restrictions extend across four platforms

Michigan said it has now obtained agreements or court orders stopping sports-related event contracts from Kalshi, Robinhood, Coinbase and Polymarket, according to G3Newswire.

The announcement places Polymarket US alongside those other platforms in Michigan’s effort to halt these offerings. The supplied account does not specify which of the other platforms stopped under agreements and which were subject to court orders.

What it means for prediction markets

  • New contracts and existing positions are both affected. Polymarket US’s agreement covers stopping new sports-related offerings to Michigan customers and closing remaining open positions.
  • November 25, 2026 is the closeout deadline. The stated cutoff is the end of that day Eastern time; the supplied account does not describe the mechanics for closing positions.
  • The stated scope is specific. The announcement concerns sports-related event contracts in Michigan, not a broader halt across contract categories or jurisdictions.
