New Jersey has asked the U.S. Supreme Court to resolve whether prediction market sports contracts fall under federal or state regulation, following conflicting appellate rulings and mounting industry uncertainty
New Jersey’s direct appeal to the U.S. Supreme Court has thrown the future of sports event contracts into sharp relief, as the state seeks to overturn a federal appellate decision that could strip states of their long-standing authority over gambling regulation. The stakes are immediate: if the Supreme Court takes the case, the justices will decide whether prediction market platforms like Kalshi can bypass state gambling laws by operating under federal commodities oversight.
Conflicting Court Rulings
The legal landscape fractured in 2026 after two federal appellate courts issued opposing decisions on the same core question: are sports event contracts on prediction markets “swaps” regulated by the Commodity Futures Trading Commission (CFTC), or are they wagers subject to state law? The Third Circuit sided with Kalshi, ruling that CFTC jurisdiction preempts state gambling statutes. Less than a week later, the Ninth Circuit reached the opposite conclusion, holding that Kalshi’s contracts are not swaps under the Commodity Exchange Act and must comply with state gaming regulations.
This split has left prediction market operators, state regulators, and tribal gaming interests in limbo. New Jersey’s 47-page Supreme Court petition argues that the issue is not just technical—it could upend the multi-billion-dollar sports betting industry by federalizing what has always been a state-controlled market. The state’s filing warns of “an explosion of litigation” and claims that companies like Kalshi are building business models around noncompliance with state law.
Industry and Regulator Responses
Kalshi, for its part, maintains that it operates as a nationwide financial exchange and cannot be subject to 50 different state regulators. Company spokesperson Dani Lever pointed to the Third Circuit and District of New Jersey rulings as evidence that CFTC jurisdiction should prevail, even as the Ninth Circuit’s decision complicates the picture. Lever insists that nothing in New Jersey’s Supreme Court filing changes Kalshi’s confidence in its legal position.
State regulators are not convinced. Nevada Gaming Control Board chairman Mike Dreitzer has publicly rejected the notion that prediction markets can sidestep state oversight by rebranding sports bets as event contracts. “Anytime you risk money on the uncertain outcome of a sporting event, that’s a bet. End of story,” Dreitzer stated at a recent hearing. He emphasized that Nevada’s regulatory framework is built on decades of precedent and that the CFTC is not a national gambling regulator. Dreitzer also acknowledged the need for regulators to adapt to new technologies, but dismissed claims that states are incapable of overseeing innovative products.
Broader Market Impact
The outcome of this legal battle will determine who sets the rules for a sector that generated $16.89 billion in state revenue from sports betting in 2025, not counting tribal casino sportsbooks. The dispute also has direct implications for tribal gaming compacts and federal statutes like the Indian Gaming Regulatory Act (IGRA) and the Wire Act, both of which hinge on the definition and regulation of gambling activity. IGRA, for example, gives tribes exclusive rights to regulate gaming on their lands if the state allows gaming, while the Wire Act criminalizes interstate sports betting unless legal in both states involved.
Additional appeals are pending in the Fourth Circuit (Maryland) and in consolidated cases involving Ohio and Tennessee, where state regulators are also seeking to enforce their own gambling laws against prediction market operators. The Supreme Court grants only about 1% of cert petitions annually, but gaming analysts estimate the odds are higher in this case due to the clear appellate split and the scale of the economic impact.
What Happens Next
New Jersey’s move comes amid a broader regulatory push for clarity in the gambling sector. As seen in reported earlier cases involving operator compliance, the question of who holds ultimate regulatory authority is not just academic—it shapes the rules, protections, and market access for every player and operator in the industry. If the Supreme Court declines to hear the case, the patchwork of conflicting rulings will persist, leaving prediction markets in a legal gray zone and inviting further litigation. If the Court takes the case, its decision will set a national precedent on the boundary between federal and state power in gambling regulation.
To understand the dispute, it’s essential to distinguish between a “swap” and a “wager.” Swaps are financial contracts regulated by the CFTC, typically used for hedging or speculation on price movements in commodities or financial indices. Wagers, by contrast, are bets on uncertain outcomes—like the result of a sports game—and have historically fallen under state gambling law. The legal status of sports event contracts on prediction markets hinges on which definition applies, and the answer will determine whether state or federal regulators have the final say.
