Key Points
- New Jersey petitions the Supreme Court seeking authority to regulate Kalshi’s sports prediction contracts
- Two federal circuit courts have reached opposite conclusions on identical regulatory questions
- The state contends Kalshi operates unlicensed sports wagering in violation of state statutes
- Kalshi, with a $22 billion valuation, maintains its products are CFTC-regulated derivative instruments
- The high court’s decision would establish nationwide precedent for prediction market regulation
New Jersey officials have escalated their legal battle against Kalshi by requesting Supreme Court intervention to resolve whether state governments possess regulatory authority over the platform’s sports-related prediction contracts.
State officials submitted their Supreme Court petition on September 2, challenging an April decision from the Third Circuit Court of Appeals. In that ruling, the appellate panel determined that the Commodity Futures Trading Commission holds exclusive jurisdiction over Kalshi’s sports event-based offerings.
Attorney General Jennifer Davenport emphasized that these entities cannot legally provide sports wagering opportunities while circumventing state regulatory frameworks. She noted widespread opposition to Kalshi’s jurisdictional arguments from numerous states representing diverse political perspectives.
Competing Circuit Court Interpretations
The appeal’s timing is significant. Just days before New Jersey’s filing, on August 28, the Ninth Circuit delivered an opposing verdict in Nevada’s litigation against Kalshi. That appellate court determined the company’s sports offerings constitute gambling wagers rather than federally supervised swap agreements, authorizing Nevada to enforce state gaming regulations.
This creates a formal circuit splitāwhen appellate courts in different jurisdictions interpret identical legal issues in contradictory ways. Such conflicts dramatically increase the probability of Supreme Court review.
Four states at minimumāNevada, Massachusetts, Michigan, and Washingtonāhave successfully obtained judicial injunctions limiting Kalshi’s business activities within their borders.
Central Issues in the Dispute
Kalshi’s position is that its offerings constitute event-based contracts falling under CFTC oversight pursuant to the Commodity Exchange Act. The current administration’s CFTC has aligned with this interpretation, initiating legal action against states attempting to apply gambling statutes to the platform.
New Jersey presents a contrasting argument: Congressional intent when enacting Dodd-Frank legislation following the 2008 economic collapse did not include transferring sports betting oversight to federal regulators. State attorneys assert the statutory language lacks sufficient clarity to preempt state jurisdiction over an industry worth billions.
The prediction market operator recently achieved a $22 billion valuation and continues aggressive market expansion.
The litigation carries the formal designation KalshiEX v. Flaherty. The Supreme Court has not yet indicated whether it will accept the case for review.
Should the justices grant certiorari, their eventual decision would establish binding precedent extending beyond Kalshi to govern the broader prediction markets sector, which currently confronts regulatory challenges and litigation across numerous jurisdictions. Standard procedure involves docketing the petition, possibly soliciting responses from opposing parties, and determining whether to grant full review.
The court has not scheduled oral arguments.
