Third Circuit Court Blocks New Jersey's Enforcement Against Kalshi Sports Event Contracts

This decision reinforces federal jurisdiction over prediction markets, potentially altering the competitive dynamics of the sports betting industry.

• On April 6, 2026, the U.S. Court of Appeals for the Third Circuit upheld a preliminary injunction favoring KalshiEX LLC against New Jersey's gambling regulations.
• The ruling cited the Commodity Exchange Act, asserting that the CFTC has exclusive authority over contracts traded on federally regulated markets.
• Kalshi's expansion into sports event contracts, initiated in January 2025, faced challenges from various states, with New Jersey issuing a cease-and-desist order in March 2025.

• KalshiEX LLC is a federally regulated exchange that began offering event contracts in 2020, expanding into sports outcomes in early 2025.
• Post-2018 PASPA repeal, nearly 40 states legalized sports betting, leading to conflicts with unlicensed prediction markets viewed as illegal gambling.
• New Jersey's legal actions against Kalshi reflect broader tensions between state regulations and federal oversight, with varying outcomes in other states like Tennessee and Nevada.

The Third Circuit's ruling is a pivotal moment in the ongoing struggle between state and federal jurisdictions over gambling and prediction markets. KalshiEX LLC, which operates as a federally regulated exchange, has been at the forefront of this legal battle since it expanded its offerings to include sports event contracts in January 2025. This move came in response to competitors launching similar products, highlighting a growing market for sports-related predictions.

The court's decision to uphold the preliminary injunction against New Jersey's enforcement actions is rooted in the Commodity Exchange Act. This act grants the Commodity Futures Trading Commission (CFTC) exclusive jurisdiction over contracts traded on designated markets. The ruling effectively preempts state regulations, allowing Kalshi to operate without the threat of state-level penalties, which could reach up to $100,000 as indicated by New Jersey's cease-and-desist order.

This legal victory is significant not only for Kalshi but also for the broader prediction market landscape. It sets a precedent that could embolden other prediction market platforms to challenge state regulations, potentially leading to a more unified federal framework for these types of contracts. The CFTC's recent certification of similar contracts without prohibition further strengthens this position, suggesting a shift towards greater acceptance of prediction markets under federal oversight.

However, the ruling is not without dissent. The 2-1 decision included a dissenting opinion arguing that states should retain their police powers to regulate gambling activities. This indicates that while Kalshi has won this round, the battle over the regulation of prediction markets is far from over. The legal landscape remains complex, with ongoing litigation in various states and the possibility of escalation to an en banc review or even the Supreme Court.

As Kalshi continues to navigate this evolving environment, its record monthly trading volume of $10.4 billion in February 2026—80% of which came from sports contracts—demonstrates the growing interest and potential profitability of this market. The implications of this ruling extend beyond Kalshi, as traditional sportsbooks like DraftKings may face increased competition, prompting them to adapt their strategies in response to the changing regulatory landscape.

• Prediction market operators: They may see increased opportunities for expansion and innovation following this ruling.
• Traditional sportsbooks: Companies like DraftKings could face competitive pressure as new entrants gain traction.
• Regulatory bodies: State gaming regulators may need to reassess their approaches to gambling laws in light of federal jurisdiction.
• Investors and traders: Those involved in prediction markets could benefit from a more stable regulatory environment, potentially leading to increased trading volumes.

• CFTC rulemaking: Keep an eye on any new regulations or clarifications from the CFTC regarding prediction markets, as these could further shape the industry.
• State responses: Monitor how other states react to this ruling, particularly those that have challenged Kalshi, as they may adjust their strategies or regulations.
• Potential appeals: Watch for any moves towards en banc or Supreme Court reviews, which could redefine the legal landscape for prediction markets.
