New Jersey asks Supreme Court to rule on Kalshi sports contract legality
New Jersey has asked the Supreme Court to rule on whether Kalshi's sports event contracts are legal trading on a CFTC-regulated exchange or illegal sports betting under state law. The filing follows conflicting federal appeals court rulings on prediction markets. Illinois is maintaining its hard-line stance against the products. Kalshi argues its contracts are regulated financial instruments, while New Jersey contends they are sports bets. The case sets up a direct conflict between federal commodity regulation and state gambling authority.
The Supreme Court now faces petitions from three separate parties — New Jersey, Crypto.com, and Robinhood — pressing the same preemption question. Each adds weight to a docket the justices cannot ignore forever. Kalshi's position crumbles with every new state filing; a cert grant is its last shot at uniform federal rules before geofence costs swallow its sports business.
The Ninth Circuit has already rejected Kalshi's theory twice, in Nevada and California, and tribal suits multiply through that opening. Traders hold positions whose validity shifts with state borders, not regulation. Legal spend compounds across parallel cases faster than any single resolution. For competing platforms, the stakes are identical: a cert denial leaves fifty state gaming commissions free to act.
