New Jersey asks Supreme Court to referee state-federal prediction market clash
Three federal appellate courts have now looked at the same question — whether sports event contracts are swaps under federal commodities law or gambling under state gaming law — and produced contradictory answers. That is not a legal ambiguity. That is a structural problem, and the Supreme Court is the only institution that can resolve it cleanly.
The sequence matters. The Third Circuit ruled in May that sports event contracts are financial instruments under exclusive CFTC jurisdiction, blocking New Jersey's cease-and-desist against Kalshi. The Ninth Circuit went the other way, ruling unanimously that the same contracts are sports wagers and that the Commodity Exchange Act does not preempt state regulation. Kalshi is now seeking en banc review from eleven Ninth Circuit judges. Robinhood and Crypto.com, having lost their preliminary injunction motion in the Ninth Circuit, filed for Supreme Court certiorari. New Jersey, the losing party in the Third Circuit, has now asked the Supreme Court to take the case as well.
When both the winning and losing parties below are running to the same court, the circuit split is not just real — it is untenable for everyone operating in the space.
Kalshi's co-founder Luana Lopes Lara has said the company wants to replicate its U.S. regulated model in Europe. That ambition is currently blocked by ESMA, which named prediction markets a systemic risk in its twice-yearly report, citing insider trading incidents including the Gannon Ken Van Dyke case — a U.S. soldier charged with placing Polymarket wagers on a raid targeting Nicolás Maduro. ESMA's language was pointed: market manipulation and insider trading risks "reach new levels" on platforms with limited identity verification. The FCA, for its part, has kept its binary options ban in place. Malta is the only EU jurisdiction actively exploring a framework.
The consensus read in this space is that Supreme Court review is likely, and that the preemption argument eventually succeeds at the federal level. I think the preemption argument is structurally sound but politically exposed in a way the consensus is underweighting. After my 2025 mispricing on a regulatory outcome — where I assigned too much weight to mechanism design and not enough to political timing — I rebuilt my framework to account for what the decision-maker's institutional incentives are, not just what the law says. A Supreme Court that has shown deference to state gambling regulatory authority in recent terms is not an automatic win for CFTC preemption, even if the text of the Commodity Exchange Act supports it.
Connecticut's enforcement action against nine platforms, including Polymarket, Robinhood, and Coinbase, did not happen in a vacuum. Governor Ned Lamont's statement that prediction markets "are not being truthful when they tell consumers that their activities are legal" is the language of a state that intends to make this costly before any federal resolution arrives. The platforms currently suspended in Connecticut are operating under a structure where the legal question is unresolved and the enforcement risk is real and immediate.
The en banc petition and the certiorari petitions are now in parallel tracks. If the Ninth Circuit grants rehearing, the Supreme Court may wait for that outcome before deciding whether to take the case. If it denies rehearing, the circuit split is locked and certiorari becomes close to unavoidable. Either way, platforms operating in the interim are pricing preemption as settled when it is not.

The Commodity Exchange Act grants the CFTC exclusive jurisdiction over financial instruments classified as swaps, which the Third Circuit ruled in May includes sports event contracts on platforms like Kalshi. This federal framework preempts state gaming laws, meaning CFTC-regulated prediction markets operate outside the reach of state cease-and-desist orders. The Ninth Circuit disagreed unanimously, classifying the same contracts as sports wagers subject to state regulation, creating a direct circuit split on whether commodities law or gambling law controls.
The Third Circuit ruled in May 2024 that Kalshi's sports event contracts fall under exclusive CFTC jurisdiction as financial instruments, not state gambling authority. New Jersey's cease-and-desist order attempted to regulate the platform under state gaming law, which the Third Circuit found was preempted by federal commodities law. This made New Jersey's enforcement action unenforceable against a federally regulated platform.
A persistent circuit split between the Third and Ninth Circuits would leave prediction market operators uncertain about whether they face federal CFTC regulation or state gambling enforcement depending on jurisdiction. Platforms like Robinhood, Crypto.com, and Kalshi would operate under contradictory legal frameworks, and states like Connecticut and New Jersey would continue filing enforcement actions against platforms claiming federal preemption. Zaid Al-Rashidi of Gambity notes that a Supreme Court deferential to state gambling authority in recent terms may not automatically side with CFTC preemption despite the Commodity Exchange Act's text supporting federal jurisdiction.
Prediction markets like Polymarket allow traders to wager on whether the Supreme Court will accept certiorari in the Kalshi and New Jersey cases and how the Court will rule on CFTC preemption. These markets price the probability of regulatory outcomes as traders incorporate signals from circuit court decisions, enforcement actions by states like Connecticut, and ESMA's designation of prediction markets as systemic risk in Europe. The resolution of these contracts depends on Supreme Court action, making the cases themselves subject to the prediction market mechanism they are being asked to regulate.
