The Supreme Court's October Term opens on 5 October 2026 with three petitions on its docket asking whether federal law pre-empts state gambling law for sports event contracts. Robinhood's, from the Ninth Circuit's ruling for Nevada, has a response due on 14 October; Crypto.com's on 15 October; New Jersey's, from the Third Circuit's ruling for Kalshi, on 9 November after an extension. Below them, the Fourth Circuit has yet to rule on Maryland's case, argued on 7 May, and a Second Circuit panel is hearing Kalshi's injunction motions in the New York and Connecticut appeals together.

population: 49 court cases over prediction-market event contracts, checked 27 September 2026, and their dated next steps.
