A court ruling deals Kalshi a major setback in Nevada
A court ruling deals Kalshi a major setback: the 9th U.S. Circuit Court of Appeals ruled Friday that Nevada can ban the prediction market platform, finding its sports event contracts are sports gambling—not federally protected swaps—and that state gaming laws are not preempted by the Commodity Exchange Act. Anyone following the viral phrasing that a court ruling deals Kashi a setback is reading about Kalshi, the designated contract market at the center of the case. The unanimous 3-0 decision rejects Kalshi's argument that it operates as a legal sports event exchange and instead sides with regulators who have long treated sports wagering as a state-licensed industry.
For anyone who grew up when sports betting meant a trip to Las Vegas or a risky offshore book, the ruling is a sharp reminder that the digital prediction-market boom still runs into the same old legal walls. Kalshi marketed itself as offering legal sports event contracts nationwide, but Nevada's gaming board—and now a federal appeals court—called that framing gambling by another name.
Key Takeaways
- The 9th Circuit upheld Nevada's authority to block Kalshi, agreeing with the Nevada Gaming Control Board that the platform's sports contracts are sports betting.
- Judges rejected Kalshi's claim that the Commodity Exchange Act preempts state gaming rules, creating a circuit split with an earlier Third Circuit decision that favored the company.
- Kalshi's own marketing described it as "the first app for legal sports betting in all 50 states," language the court cited against the company.
- The CFTC told the New York Times the Ninth Circuit "erred," signaling the fight may head toward the Supreme Court.
- Kalshi said it will seek further review, so the platform's nationwide ambitions are far from settled.
What happened in the Kalshi court ruling?
In March 2025, the Nevada Gaming Control Board sent Kalshi a cease-and-desist letter, arguing the company operated an unlicensed sports betting platform in violation of state gaming regulations. Kalshi pushed back, saying it is a designated contract market offering legal sports event contracts, or "swaps," under federal commodity law.
The appeals court was not persuaded. Judge Ryan D. Nelson wrote for the unanimous panel that "the substance of the sports event contracts offered on Kalshi's DCM is sports gambling, regardless of whether Kalshi calls them swaps." The judges also pointed to Kalshi's marketing, which advertised the service as "the first app for legal sports betting in all 50 states."
Nevada Gaming Control Board Chairman Mike Dreitzer said in a statement that the decision "completely vindicates what we have been saying all along" and that sports betting "needs to be properly regulated by the state." Kalshi spokeswoman Dani Lever told the Nevada Independent that the company will seek further review.
Why does this court ruling matter for prediction markets?
Prediction markets like Kalshi allow people to effectively gamble on sports, and Friday's unanimous decision spells trouble for that model when states decide contracts function as wagers. The Nevada case tests whether those platforms can operate under federal commodity rules or must submit to the same state-by-state licensing regimes that govern casinos and sportsbooks.
The ruling lands as regulators elsewhere push back too. Mashable reported that New York has sued Kalshi, claiming it is unlicensed gambling, and that France ordered Polymarket blocked over illegal gambling promotion—signs that the prediction-market free-for-all faces growing scrutiny.
At the center is preemption: Kalshi argued the Commodity Exchange Act blocks states from treating its swaps as gambling. The 9th Circuit concluded it does not. That directly conflicts with an earlier Third Circuit decision from Philadelphia that backed Kalshi's position, setting up a circuit split that federal officials say demands Supreme Court resolution.
How does this fit the 'then and now' of sports betting?
For decades, legal sports betting in the United States was concentrated in Nevada, a desert outlier where casino culture and regulatory expertise developed side by side. The rest of the country lived with illegal bookies, office pools, and later offshore apps—a patchwork that felt permanent even as attitudes toward wagering slowly shifted.
The "now" chapter promised smartphone sportsbooks in dozens of states and, more recently, prediction-market apps pitching event contracts as something different from traditional gambling. Mashable noted Kalshi gained roughly three million users amid World Cup gambling buzz, underscoring how quickly that narrative spread. Yet the Nevada ruling shows the "then" never fully disappeared: states that built gaming empires still decide who gets a license, and federal commodity law does not automatically erase those gates.

What happens next for Kalshi?
Kalshi is not shutting down nationwide on the strength of one appeals court order, but the setback is significant. The company plans to pursue further review, which could mean additional appeals before the 9th Circuit or an eventual petition to the U.S. Supreme Court. Until then, Nevada can enforce its ban, and other states watching the case may feel emboldened to act.
Zach Fulton, a spokesman for the Commodity Futures Trading Commission, told the New York Times that the Ninth Circuit erred and that the circuit split "calls out for resolution by the Supreme Court." That agency disagreement highlights how unsettled the regulatory landscape remains—even as consumers treat prediction apps like the next evolution of fandom and finance.
For Kalshi users, the practical question is whether contracts tied to game outcomes will stay available without state licenses. For regulators, the question is whether innovation outpaces law or finally meets it. Friday's ruling suggests that in Nevada, at least, the old rules still win when courts look past labels to substance.
The court ruling deals Kalshi a major setback today, but the broader fight over prediction markets, sports betting, and who gets to set the rules is only heating up. In a country that spent a generation debating where wagering belongs, the answer is once again being written state by state—and possibly soon, at the highest court in the land.
