Trump Administration Loses Kalshi Court Challenge Over Prediction Market Betting
Federal courts split sharply on prediction market regulation, with Third Circuit backing CFTC federal authority while Ninth Circuit allows state bans.
Objective Facts
In the first federal appeals ruling on state regulation of prediction markets, a Third Circuit panel ruled 2-1 on April 6 in favor of Kalshi against New Jersey's attempt to regulate sporting event contracts. Circuit Judge David J. Porter agreed with Kalshi that its event contracts constitute 'swaps,' a type of derivative contract exclusively regulated by the Commodity Futures Trading Commission under the Commodity Exchange Act. However, the Ninth Circuit reached the opposite conclusion, allowing Nevada to maintain its ban on Kalshi. A federal judge blocked Arizona's unprecedented criminal case against Kalshi on April 10, issuing a temporary restraining order that blocks Arizona from proceeding with the first criminal prosecution ever brought against a CFTC-registered prediction market operator. The CFTC, backed by the U.S. Department of Justice and the Trump administration, escalated its response to state pushback on April 2, filing lawsuits against Arizona, Connecticut, and Illinois seeking declaratory judgments that the Commodity Exchange Act gives the agency exclusive authority over event contracts. Thirty-nine attorneys general from across the political spectrum had already sided with the state of Nevada in its battle to enforce its gambling laws against Kalshi.
Left-Leaning Perspective
Connecticut Attorney General William Tong accused the Trump administration of 'recycling industry arguments' that have been rejected in district courts across the country, stating 'These contracts are plainly unlicensed illegal gambling under time-worn state law, and we will aggressively defend Connecticut's commonsense consumer protection laws'. Illinois Governor JB Pritzker said in a statement that the Trump administration is 'carrying water for companies driving well-documented and lucrative insider trading schemes,' saying the Trump administration is putting profits over consumers. House Democrats including Reps. Gabe Amo, Greg Casar, Jamie Raskin, Dina Titus, and Yassamin Ansari questioned why the CFTC had not taken public action against war bets and whether it has the authority to regulate insider trading on prediction markets. Judge Jane Roth argued in dissent that Kalshi's offerings are 'virtually indistinguishable from the betting products available on online sportsbooks, such as DraftKings and FanDuel' and ridiculed Kalshi's 'branding' of wagers as 'sports-event contracts' as 'acts of alchemy' that try to 'transmute its products from sports gambling to futures trading'. Roth emphasized a longstanding presumption against preemption in public health and safety fields traditionally occupied by states, noting that 'throughout U.S. history,' states have overseen gambling regulation as a potentially harmful 'vice activity' and can use their powers to promote the 'welfare, safety and morals' of their citizens, using sports betting laws to 'protect the public from gambling addiction'. Todd Phillips, a Georgia State University professor who focuses on financial regulation, said the federal lawsuits represent 'trying to put a thumb on the scale for prediction markets'. Left-leaning coverage emphasizes insider trading concerns and consumer protection, with Democratic officials pointing to suspicious trading patterns on Polymarket before major announcements. They argue prediction markets are essentially sports gambling being repackaged with corporate terminology to evade state regulation, and that allowing federal preemption undermines states' traditional authority over gambling and ability to protect their citizens from addiction and fraud.
Right-Leaning Perspective
Circuit Judge David Porter concluded that the Commodity Exchange Act preempts state laws that directly interfere with swaps traded on CFTC-licensed designated contract markets, finding that Kalshi's sports event contracts are swaps within the meaning of the Act and that 'the CFTC has exclusive jurisdiction'. CFTC Chairman Michael S. Selig characterized Arizona's prosecution as a 'dangerous precedent' and argued that Congress had 'specifically rejected such a fragmented patchwork of state regulations because it resulted in poorer consumer protection and increased risk of fraud and manipulation'. Selig said on CNBC that 'What we're seeing is an attempt by the state gaming commissions to effectively nullify federal law'. The Kalshi prediction markets ruling essentially puts federal authority above state gambling regulators, with the ruling validating Kalshi's entire business model that its contracts are regulated financial instruments not gambling products, and the distinction being worth potentially billions in market opportunity. Chief U.S. Circuit Judge Michael Chagares, a George W. Bush appointee, also ruled in favor of Kalshi, noting that while appearing nearly identical to traditional sports betting, a few technical distinctions separate event contracts for sporting events, with no house to bet against in event contracts. The Kalshi prediction markets ruling represents the biggest legal victory the industry has ever seen, with a three-judge panel of the Third Circuit Court of Appeals ruling 2-1 on April 6 that New Jersey cannot regulate Kalshi's sports-related event contracts, effectively shielding CFTC-licensed prediction markets from state gambling enforcement, marking the first time a federal appeals court has weighed in on this central battleground. Right-leaning coverage frames this as a victory for federal regulatory authority over fractured state regimes, emphasizing that prediction markets are legitimate financial instruments governed by a comprehensive federal framework. They argue that allowing CFTC licensing to preempt state gambling laws creates uniform national protections and prevents the inefficiency and consumer harm caused by a patchwork of contradictory state regulations.
Deep Dive
The prediction market litigation represents a fundamental federalism clash with enormous economic implications. At stake is approximately $16.8 billion in sports-related trading volume on platforms like Kalshi alone, with potential expansion if federal preemption holds. The Third Circuit's April 6 ruling for federal preemption appears to contradict the Ninth Circuit's stance allowing Nevada's ban, creating precisely the circuit split that typically leads to Supreme Court review. The Trump administration's position—that prediction markets are federally regulated financial derivatives under the Commodity Exchange Act—rests on technical distinctions that critics argue are illusory. Judge Roth's dissent effectively highlighted this tension: Kalshi's own marketing materials call these products 'sports betting,' the mechanics are indistinguishable from sportsbooks, and the outcomes traded are identical to traditional bets. However, the majority opinion's framing of the question narrowly—not whether states can regulate gambling broadly, but whether they can regulate trading on federally licensed exchanges—provides technical legal ground for preemption. This narrow framing is crucial: it potentially preserves state authority over gambling more generally while carving out federal jurisdiction specifically over CFTC-licensed platforms. What each perspective gets right: States have a strong historical claim to gambling regulation and legitimate interests in consumer protection, problem gambling prevention, and tax revenue (Illinois noted sportsbooks generated $1.1 billion in state taxes). The Trump administration correctly notes that the 1974 creation of the CFTC reflected Congressional intent to replace state patchwork regulation with federal uniformity in commodities and futures markets. The left correctly identifies potential for insider trading abuse (the Iran ceasefire bets exemplifying this), while the right correctly observes that federal oversight could provide more comprehensive fraud prevention than fractured state systems. What remains unresolved: The ultimate question whether the Commodity Exchange Act's scope extends to event contracts tied to non-financial outcomes (sports, politics, wars) was genuinely ambiguous before this litigation. The April 6 ruling settled it for the Third Circuit but the Ninth Circuit's opposite conclusion means the Supreme Court will likely need to decide. Also unresolved is whether the CFTC, designed to regulate commodities and financial derivatives, possesses institutional expertise adequate to its new role regulating prediction markets on military strikes and elections. The April 10 blocking of Arizona's criminal case suggests courts are increasingly skeptical of state enforcement power, but Nevada's preliminary injunction remains in place pending Ninth Circuit oral argument scheduled for mid-April.
