New Jersey’s attorney general and state gaming authorities have asked the US Supreme Court to review a dispute involving Kalshi’s sports event contracts. The officials filed a petition for a writ of certiorari, seeking the court’s consideration of whether Kalshi can offer contracts tied to sporting events to residents of the state. The filing places New Jersey’s gaming regulators in a legal challenge over the availability of prediction-market products within its jurisdiction. Cointelegraph reported the petition on September 2, 2026. The source material does not provide details on the arguments presented, the lower-court proceedings, or whether the Supreme Court will agree to hear the case.
