Key Takeaways
- New Jersey petitioned the Supreme Court to determine state regulatory authority over Kalshi’s sports prediction markets
- Two federal circuit courts have issued contradictory decisions on the identical legal question
- New Jersey contends Kalshi operates unlicensed sports gambling in violation of state law
- Kalshi, with a $22 billion valuation, maintains its offerings are CFTC-regulated swaps under federal jurisdiction
- The Supreme Court’s decision would establish nationwide precedent affecting prediction market platforms
New Jersey’s attorney general has escalated a critical legal fight by requesting Supreme Court intervention to determine whether states maintain regulatory control over Kalshi’s sports prediction market platform.

The petition, submitted September 2, challenges an April decision from the Third US Circuit Court of Appeals that favored Kalshi. That ruling determined the US Commodity Futures Trading Commission holds exclusive regulatory power over the platform’s sports-related contracts.
Attorney General Jennifer Davenport emphasized that these entities cannot legally provide sports wagering services while bypassing state regulations. She highlighted that numerous states, representing diverse political viewpoints, have challenged Kalshi’s interpretation.
Conflicting Circuit Court Decisions
The petition arrives amid significant judicial disagreement. Just days before New Jersey’s filing, on August 28, the Ninth Circuit Court of Appeals delivered a contrasting verdict in Nevada’s case against Kalshi. That panel determined Kalshi’s sports-focused contracts constitute sports wagers rather than federally supervised swaps, affirming Nevada’s authority to enforce state gaming regulations.
This ruling stands in stark opposition to the Third Circuit’s interpretation. Such circuit splitsāwhen federal appeals courts deliver conflicting judgments on identical legal issuesāsubstantially increase the likelihood of Supreme Court review.
Multiple states have already secured judicial relief, with Nevada, Massachusetts, Michigan, and Washington obtaining court-ordered limitations on Kalshi’s activities within their borders.
The Core Legal Dispute
Kalshi’s position centers on classifying its offerings as event-based contracts subject to CFTC oversight under the Commodity Exchange Act. The Trump administration’s CFTC has endorsed this interpretation, initiating litigation against states attempting to apply gambling statutes to the platform.
New Jersey presents a contrasting interpretation, asserting that Congress did not intend to transfer sports betting oversight to a federal regulatory body when enacting the Dodd-Frank Act following the 2008 economic collapse. State officials argue the statutory language lacks sufficient clarity to preempt state jurisdiction over this multi-billion dollar sector.
The prediction market operator recently achieved a $22 billion valuation while aggressively expanding its market presence.
The dispute bears the formal title KalshiEX v. Flaherty. The Supreme Court has not yet indicated whether it will grant certiorari.
Should the justices accept the case, their decision would establish binding precedent extending beyond Kalshi to encompass the broader prediction markets industry, which currently confronts litigation and regulatory restrictions across numerous jurisdictions. Standard procedure involves docketing the petition, potentially soliciting a response from Kalshi, and determining whether to grant full review.
The Court has not scheduled oral arguments.
