Robinhood & Polymarket v. Michigan
For the states PIs denied; appeals pending; Robinhood paused Michigan sports contracts
Judge Paul Maloney denied both companies preliminary injunctions on June 19, 2026, finding no clear congressional intent to displace state gambling regulation. Their Sixth Circuit appeals are proceeding on a regular schedule after the court declined to fast-track them with Kalshi's Ohio and Tennessee appeals. Under a court-approved stipulation entered Sept. 4, 2026, Robinhood stops offering new sports contracts to Michigan customers and must close open positions by Oct. 9, while Michigan forbears from enforcement.
