New Jersey has asked the U.S. Supreme Court to settle whether sports-related event contracts offered by federally regulated prediction markets are financial derivatives governed by federal law or wagers that states may police under their own gambling statutes.
Attorney General Jennifer Davenport filed a 332-page petition for a writ of certiorari seeking review of a U.S. Court of Appeals for the Third Circuit ruling that favored prediction-market operator Kalshi. The petition places a growing conflict between state gaming authorities and the Commodity Futures Trading Commission before the country’s highest court, though the justices must first decide whether to take the case.
New Jersey’s challenge grew out of a cease-and-desist letter sent to Kalshi last year. State officials alleged that the platform’s sports-related contracts violated New Jersey gambling law. Kalshi responded by suing, arguing that the contracts fall within the Commodity Exchange Act and are subject to CFTC oversight rather than state gambling restrictions.
The Third Circuit agreed with Kalshi, handing the company a significant victory in its dispute with New Jersey. Davenport’s petition now asks the Supreme Court to define where federal derivatives regulation ends and state gambling enforcement begins when contracts are tied to the outcomes of sporting events.
New Jersey argues sports contracts raise state gambling concerns
In a statement accompanying the filing, Davenport said state gambling regulation addresses risks including compulsive gambling, underage participation and insider trading connected to sports games.
Those concerns go beyond the legal labels attached to the products. Sportsbooks are generally licensed and supervised state by state, often subject to requirements involving age checks, responsible-gambling safeguards, integrity monitoring and reporting. Prediction-market platforms offering event contracts have argued that their products belong in a different regulatory category because they are traded as derivatives contracts under federal commodities law.
The distinction carries practical consequences for operators. A finding that state gambling laws apply could expose platforms to licensing requirements, enforcement actions or restrictions in jurisdictions where they do not hold sports-betting licenses. A finding that federal derivatives law preempts those rules would give CFTC-regulated platforms a clearer path to offer eligible contracts across state lines.
Kalshi said through a spokesperson that it disagrees with New Jersey’s filing. The company has maintained in litigation that federal law gives the CFTC authority over its event-contract products.
Conflicting court rulings increase pressure for review
The petition follows a separate setback for Kalshi in Nevada. An appeals court last week upheld a lower-court decision concluding that Kalshi had not shown that CFTC authority preempted Nevada’s power to regulate sports betting.
That result conflicts with the Third Circuit’s approach in the New Jersey dispute. The differing outcomes leave prediction-market operators facing different legal conditions across jurisdictions, even when the underlying question concerns the same federal statute and similar sports-linked contracts.
New Jersey’s petition frames that disagreement as a reason for Supreme Court intervention. The justices receive thousands of certiorari petitions each term and accept only a small share, but splits among federal appeals courts are a common basis for review because they can produce inconsistent national rules.
A Supreme Court case would not automatically determine the legality of every type of prediction-market contract. The Court would be examining the interaction between the Commodity Exchange Act, the CFTC’s authority and state gambling laws in the context of the products presented by the dispute. Its reasoning could nevertheless shape how regulators and courts assess contracts linked to elections, economic data, entertainment and sports.
CFTC defends exclusive federal authority
The CFTC has argued that it holds “exclusive jurisdiction” over the derivatives products at issue under the Commodity Exchange Act. Under Chair Michael Selig, the agency has sued several states and proposed a framework for regulating prediction markets, according to the material provided with the dispute.
The federal regulator’s position places event contracts within a market structure designed for derivatives rather than traditional gaming. States counter that a contract whose payoff turns on a sports result can function much like a wager, regardless of the federal registration status of the platform listing it.
That tension is especially sharp in sports markets. A contract allowing a trader to take a position on whether a team will win may resemble a sportsbook bet from the user’s perspective, even if the platform treats the transaction as a standardized derivative contract. The legal dispute turns partly on whether that resemblance gives states room to enforce gambling rules or whether Congress displaced that authority through the Commodity Exchange Act.
The case also tests the limits of a regulatory model in which federally supervised market infrastructure can offer products connected to activities traditionally regulated locally. States have long treated sports betting as an area requiring jurisdiction-specific controls, while the CFTC’s derivatives regime generally operates nationally.
Market operators face an unsettled state-by-state landscape
Until the Supreme Court acts, or declines to act, the conflicting rulings leave operators and users with a fragmented legal landscape. The Third Circuit’s decision supports Kalshi’s position in its dispute with New Jersey, while the Nevada ruling gives that state a stronger basis to pursue its own sports-betting rules.
The immediate next step is procedural. New Jersey’s petition will be considered by the Supreme Court, and Kalshi will have an opportunity to respond. If the Court denies review, the appellate decisions will remain in force within their respective jurisdictions without establishing a single nationwide standard. If it grants review, the resulting case could provide the first definitive Supreme Court guidance on how sports-linked prediction contracts fit within federal commodities law and state gambling authority.
For now, the litigation places prediction markets at the center of a jurisdictional fight rather than a simple debate over product design. The outcome will determine whether sports event contracts can rely on federal derivatives oversight alone or must also operate within the state-by-state rules governing gambling.
