Polymarket US has agreed to stop offering new sports-related event contracts to Michigan customers and close residents’ remaining open positions by 25 November 2026, according to the report. A federal court approved the agreement, which the report says follows similar deals with Coinbase and Robinhood and a preliminary injunction against Kalshi.
Polymarket US will stop selling new event contracts related to sports to Michigan customers, and open positions held by residents of that state will be closed by November 25 2026. A federal court approved the agreement, which came after comparable deals with Coinbase and Robinhood and a preliminary injunction against Kalshi.
The Michigan Gaming Control Board said a court-approved agreement requires Robinhood Derivatives to stop offering new sports-event contracts to Michigan customers by the end of 9 September 2026. Existing positions must close by 9 October; the agreement does not concede either side’s legal position and remains in effect until appeals before the Sixth Circuit conclude.
Robinhood agreed to withdraw sports event contracts from Michigan pending court proceedings. The withdrawal extends at least until the Sixth Circuit rules on appeals involving Robinhood, Coinbase and Kalshi, alongside a state court case against Kalshi.
A Michigan court issued a preliminary injunction barring Kalshi from offering or facilitating online sports betting to Michigan residents or through channels accessible in the state. The order follows a lawsuit by Attorney General Dana Nessel alleging unlicensed sports betting; it remains in force until a final judgment, according to the report.
It was reported that the CFTC told Kalshi to continue sports contracts in Michigan and settle existing trades, contrary to a state court order. Kalshi challenged state oversight on federal-law grounds and still faces a geofencing deadline in August.
