A federal appeals court has delivered a significant win for prediction market platform Kalshi, blocking New Jersey gaming authorities from taking enforcement action against the company. The ruling, issued on April 4, 2026, by the U.S. Court of Appeals for the Third Circuit, strengthens the argument that federal regulators, not states, hold primary authority over these novel financial products. This decision creates a direct conflict with other state-level actions and sets the stage for a potential Supreme Court showdown over the future of prediction markets in the United States.
Court Rules CFTC Jurisdiction Prevails
In a 2-1 decision, a panel of judges affirmed a lower court’s preliminary injunction that stopped New Jersey’s Division of Gaming Enforcement. The core legal question was whether state gambling laws or the federal Commodity Exchange Act applied to Kalshi’s contracts. The majority found Kalshi had a “reasonable chance of success” in arguing that the Commodity Futures Trading Commission (CFTC) has “exclusive jurisdiction.”

Circuit Judge David J. Porter wrote the opinion. He stated that allowing New Jersey to enforce its laws would “create an obstacle” to federal regulation. “This state regulation is exactly the patchwork that Congress replaced wholecloth by creating the CFTC,” Porter wrote. The judges agreed that sports-related event contracts offered on a CFTC-licensed platform like Kalshi’s designated contract market (DCM) fall under the CFTC’s purview as swaps.
This suggests a clear federal preemption argument has gained traction. Industry watchers note that the ruling provides a powerful legal shield for Kalshi and similar platforms against state gambling enforcement, at least within the Third Circuit’s jurisdiction.

A Sharp Dissent and the Gambling Question
The ruling was not unanimous. Circuit Judge Jane Roth issued a forceful dissent, framing the issue in starkly different terms. She argued that Kalshi’s products are “virtually indistinguishable” from traditional sports betting. Roth called the company’s legal positioning a “performative sleight meant to obscure the reality that Kalshi’s products are sports gambling.”
Her dissent highlights the central tension regulators are grappling with. Is a contract on the outcome of a football game a financial derivative or a bet? Judge Roth warned the majority’s analysis could “radically upend the legal market governing the gambling industry.” This fundamental disagreement is why many legal experts believe the Supreme Court may ultimately need to intervene.
CFTC Chair Doubles Down on Federal Control
The appeals court decision aligns perfectly with the CFTC’s aggressive recent stance. Under Chair Michael Selig, the agency has consistently claimed exclusive jurisdiction over event contracts. Data from the CFTC shows a concerted push in 2025 and early 2026 to establish its authority.
In the last four months alone, the CFTC has opened a proposed rule for public comment, filed legal briefs supporting its position in other courts, and even sued three states—Arizona, Connecticut, and Illinois—to block their regulatory efforts. Selig reiterated the agency’s broad view at a policy summit on April 4, 2026. “Our definition of commodity and statute is very broad,” Selig said. “It includes events on sports, it includes events in politics, it includes corn and grains and all sorts of things.”
He argued for consistent regulation, whether the contract is based on grain prices or a presidential election. But Selig also noted exceptions for contracts “readily susceptible to manipulation,” indicating the CFTC sees its role as a careful regulator, not a passive observer.
The State-Level Patchwork Problem
While Kalshi prevailed in Philadelphia, it faces battles elsewhere. Just days before the Third Circuit ruling, a Nevada judge extended a ban on the company offering certain event-based contracts. This conflicting patchwork of state-level rulings creates immense uncertainty for the industry.
What this means for investors and operators is a fragmented market. A contract might be legal under federal and Third Circuit law but banned in Nevada. This inconsistency increases operational costs and legal risks. The current situation mirrors the pre-2018 field for sports betting, which was also a state-by-state patchwork before the Supreme Court’s landmark decision.
Implications for the Prediction Market Industry
The Third Circuit’s decision is a major boost for Kalshi and its backers. CEO Tarek Mansour called it “a big win for the industry and millions of users” in a social media post. The ruling provides a legal roadmap for other platforms to challenge state enforcement actions.
However, the victory is not absolute. The case now returns to the lower court for a full trial on the merits. The appellate court only ruled on the preliminary injunction, finding Kalshi was likely to succeed. The final outcome could still differ. Furthermore, the ruling only applies directly to New Jersey and potentially other states within the Third Circuit.
Key factors for the industry’s future now include:
- The CFTC’s final rulemaking: How the agency formally defines and regulates event contracts will set the national standard.
- Outcomes in other circuits: Rulings from the Ninth Circuit (in the Nevada case) or others could contradict the Third Circuit, forcing the Supreme Court’s hand.
- State legislative responses: States may attempt to craft new laws specifically targeting prediction markets if traditional gambling statutes are preempted.
Conclusion
The Third Circuit’s ruling in favor of Kalshi marks a major moment in the struggle over prediction markets. It strengthens the CFTC’s position as the primary regulator and delivers a setback to states seeking to treat these markets as gambling. But with a powerful dissent and active battles in other courts, the legal war is far from over. The conflicting rulings increase the probability that the U.S. Supreme Court will eventually decide whether a bet on the future is a gambling slip or a financial instrument. For now, Kalshi has won a decisive battle in its fight against New Jersey regulators.
FAQs
Q1: What exactly did the appeals court decide?
The U.S. Court of Appeals for the Third Circuit upheld a lower court order that prevents New Jersey gaming authorities from enforcing state gambling laws against Kalshi. The 2-1 majority agreed that federal commodity law likely preempts state law in this case.
Q2: Why is the CFTC involved in what looks like sports betting?
The CFTC regulates derivatives, including swaps and futures. Kalshi is licensed as a designated contract market (DCM) with the CFTC, arguing its event contracts are financial swaps based on future occurrences, not traditional wagers. The court accepted this framing for the preliminary injunction.
Q3: Does this mean prediction markets are now legal everywhere?
No. This ruling is specific to New Jersey’s action against Kalshi within the Third Circuit. Other states, like Nevada, are actively challenging Kalshi and similar platforms. The legal field remains fragmented.
Q4: What was the main point of the judge’s dissent?
Circuit Judge Jane Roth argued that Kalshi’s products are effectively sports gambling disguised as financial contracts. She warned that the majority’s decision could destabilize the existing legal framework for gambling regulation in the United States.
Q5: What happens next in this legal fight?
The case goes back to the district court for a full trial. Meanwhile, the CFTC is proceeding with its own rulemaking process for event contracts, and other federal circuits are hearing similar cases. The conflict between state and federal authority may need to be resolved by the Supreme Court.
