New Jersey Files Supreme Court Petition on Prediction Market Contracts

On September 2, 2026, New Jersey Attorney General Jennifer Davenport submitted a petition for a writ of certiorari to the U.S. Supreme Court, and this action directly challenges whether platforms such as Kalshi may list sports-event contracts without adhering to individual state gambling statutes. The filing highlights tensions between federal oversight under the Commodity Futures Trading Commission and state regulatory powers, while lower courts have issued opposing decisions on the same core questions. The petition seeks clarification on preemption under the 2010 Dodd-Frank Act, which expanded the CFTC's authority over swaps and related instruments. Kalshi and comparable operators maintain that their event contracts qualify as swaps subject exclusively to federal rules, yet state officials in New Jersey argue that sports-related offerings fall under traditional gambling enforcement. Conflicting circuit court opinions have created uncertainty across jurisdictions, with the Third Circuit leaning toward federal preemption and the Ninth Circuit upholding state authority in parallel disputes.

Details of the Certiorari Petition

The document submitted by the New Jersey Attorney General's office requests Supreme Court review of specific issues surrounding sports-event contracts on prediction market platforms. According to the filing, these contracts involve outcomes tied to athletic competitions, and the state contends that such products require compliance with New Jersey gambling laws regardless of any federal swap designation. The petition emphasizes that allowing platforms to bypass state rules would undermine established regulatory frameworks designed to protect consumers and maintain market integrity.

Observers note that writs of certiorari remain discretionary, so the Supreme Court may decline the case, yet the presence of split decisions between circuits often increases the likelihood of acceptance. The Third Circuit previously determined that CFTC regulation preempts certain state claims, whereas the Ninth Circuit reached the opposite conclusion in a separate matter involving similar platforms. This divergence leaves operators and regulators without uniform guidance on how to proceed nationwide.

Background on Conflicting Lower Court Rulings

Legal proceedings leading to the current petition began with challenges from prediction market firms against state enforcement actions. In the Third Circuit, judges concluded that Dodd-Frank amendments placed swaps and event contracts under exclusive federal jurisdiction, which limited state intervention. The Ninth Circuit, by contrast, held that state gambling statutes retain force when contracts involve sports outcomes, even if the CFTC has approved the platform for other products. These rulings emerged from distinct factual records and statutory interpretations, and they produced inconsistent obligations for companies operating across multiple states.

Industry participants have tracked these cases closely because they affect product availability and compliance costs. Kalshi has argued in filings that its contracts meet the statutory definition of swaps, which receive protection from state-level restrictions under the Commodity Exchange Act as amended. State regulators counter that sports-event contracts carry unique risks and consumer protection concerns that fall outside the scope of federal swap rules, and they point to legislative history supporting continued state oversight.

Role of the Dodd-Frank Act and CFTC Authority

The Dodd-Frank Wall Street Reform and Consumer Protection Act broadened the CFTC's mandate to include oversight of swap markets, and this expansion forms the central legal question in the petition. Federal law defines swaps broadly to encompass certain contingent payment agreements, yet the statute contains explicit language preserving state authority in designated areas. The New Jersey filing asks the Supreme Court to resolve whether that preservation clause extends to sports-event contracts or whether CFTC approval overrides state gambling prohibitions entirely.

According to the Commodity Futures Trading Commission, approved platforms must adhere to federal position limits and reporting requirements, while state officials maintain separate licensing and consumer safeguards. The petition references these dual frameworks and seeks a definitive ruling on which regime controls when the two conflict. A second external reference appears in reports from the International Organization of Securities Commissions, which examined cross-border treatment of event contracts and noted varying national approaches to sports-related derivatives.

Arguments Presented by Platform Operators

Kalshi and similar entities have consistently stated that their offerings constitute regulated swaps rather than gambling products, and they cite CFTC registration as evidence of federal exclusivity. The companies assert that uniform national rules promote innovation and reduce compliance burdens compared with a patchwork of state laws. Court records show these operators have obtained no-action relief or formal approvals for certain contracts, yet they face ongoing litigation when states attempt to enforce local statutes against sports-specific listings.

State representatives respond that federal swap regulation does not automatically displace gambling statutes enacted to address public policy concerns unique to athletic events. The New Jersey petition compiles these positions and requests Supreme Court intervention to establish a single standard that applies across circuits. Resolution of the issue would affect not only Kalshi but also other prediction market platforms seeking to expand their contract offerings.

Conclusion

The September 2026 filing by New Jersey Attorney General Jennifer Davenport places the question of prediction market preemption squarely before the Supreme Court. Conflicting circuit decisions have left regulators and operators without clear direction, and the outcome of the certiorari petition will determine whether state gambling laws continue to apply to sports-event contracts or whether federal CFTC authority governs exclusively. The case centers on statutory interpretation of the Dodd-Frank Act and the scope of swap definitions, with both sides presenting established legal arguments drawn from prior rulings and legislative text.
