If there was one state where the prediction-market industry needed to win the "we're not gambling" argument, it was Nevada. The state that built its economy on licensed wagering was never going to let a federally registered exchange sell sports outcomes to its residents without a fight. On August 28, 2026, Nevada won that fight at the federal appeals level, and it did so unanimously.
What happened
A three-judge panel of the U.S. Court of Appeals for the Ninth Circuit ruled 3-0 against Kalshi in its dispute with the Nevada Gaming Control Board, according to Nevada Current and the published opinion (No. 25-7516). The key points, as reported:
- The court affirmed a district court order dissolving Kalshi's preliminary injunction, the order that had been protecting Kalshi from Nevada enforcement while the case proceeded.
- The panel treated Kalshi's sports-event contracts as sports bets rather than federally regulated swaps. In reporting summarized by Sports Betting Dime and others, the court's view was that the substance of the contracts is sports gambling, whatever label Kalshi puts on them.
- The result leaves Nevada regulators free to keep enforcing state gambling law against the platform. The Nevada Independent summarized it bluntly: a federal appeals court "allows Nevada to ban Kalshi and other prediction markets."
The Nevada Gaming Control Board publicized the win in a press release. The outcome had been foreshadowed in April 2026, when Nevada Current reported that the panel appeared to lean Nevada's way at oral argument in the fight with Kalshi and Crypto.com.
The California and tribal aftershock
Nevada was not the only Ninth Circuit problem. According to Legal Sports Report, Kalshi blocked access to its prediction markets on three California tribal reservations after a federal appeals court ruling found its sports contracts likely violate tribal gaming laws. Sportico has argued that the tribal case, involving the Blue Lake Rancheria, could also draw the Supreme Court's attention.
For users, that means something concrete: the same app can be available on one side of a reservation boundary and geo-blocked on the other.
Why futures and prop traders should care
Most futures traders don't trade sports contracts, but many of us trade on platforms that are rushing to add them. Brokers want event contracts because they bring new users and new volume. The Ninth Circuit's ruling is a reminder that the product sitting next to your ES chart can have a totally different legal status than the ES contract itself.
It also matters because the argument in this case is about labels. Kalshi's position is that a CFTC-registered venue makes its contracts derivatives. Nevada's position, which the court accepted, is that the substance of a sports contract is a bet. Traders who care about keeping index and commodity futures clearly on the "financial product" side of that line have a stake in how it gets drawn.
The controversy: consumer protection or turf protection?
Nevada's side: sports wagering in the state is licensed, taxed, age-limited and supervised. A platform that offers the same economic bet without any of that is, in the state's view, operating an unlicensed sportsbook.
The industry's side: Kalshi and its allies argue that Congress gave the CFTC exclusive jurisdiction over contracts on federally registered exchanges, and that a state gaming board should not be able to override that. They also point out that the Third Circuit agreed with them earlier in 2026 in a New Jersey case.
Our take
Our take: It's easy to frame this as Nevada protecting its casino industry, and there is surely some of that. But the more important point is that the court looked through the packaging. A trader should welcome that instinct. The retail trading world is full of products whose wrappers promise one thing and whose economics deliver another. A legal system that asks "what is this really?" is on our side more often than not.
The uncomfortable question: if the substance of a sports contract is gambling, what is the substance of a 0DTE lottery-ticket option bought five minutes before expiration? Regulators haven't asked that yet. Someone eventually will.
What traders should do (general, not advice)
- Check whether event contracts are actually available in your state before funding an account for them.
- Expect access to change quickly, including on tribal lands and across state lines.
- Keep the legal status of any product you trade in mind. "Listed on a regulated exchange" is not the end of the analysis.
Key takeaways
- On August 28, 2026, the Ninth Circuit ruled 3-0 for Nevada, affirming the dissolution of Kalshi's preliminary injunction.
- The court treated Kalshi's sports-event contracts as sports gambling subject to state law, not as federally regulated swaps.
- Kalshi also geo-blocked three California tribal reservations after a separate appeals ruling on tribal gaming law.
- The Ninth Circuit's view conflicts with the Third Circuit's pro-Kalshi ruling, adding pressure for Supreme Court review.
- Our view: courts looking past product labels to substance is good for traders overall.
