The Ninth Circuit Court of Appeals rejected prediction markets platforms’ requests for injunctive relief against the Nevada Gaming Control Board, concluding that sports-related event contracts are not a derivative regulated by the federal government.
The court rejected appeals by Kalshi and Crypto.com, two prediction market platforms, to stop Nevada from halting their operations which the state claims are gambling offerings outside of the gaming control board’s framework. The court also ruled against Robinhood’s request for injunctive relief. That firm also features event contracts on its trading platform.
Under scrutiny were the platforms’ sports-related event contract offerings, which 44 states argue are nothing more than sports betting. However, the platforms — and their federal regulator, the Commodity Futures Trading Commission — claim all event contracts, no matter the topic, are swaps. Swaps are a type of derivative under the purview of the CFTC, and the agency asserts that it has the exclusive jurisdiction to regulate all event contracts.
The CFTC has even sued nine states to defend what it believes is its sole right to make rules for prediction markets.
But the ninth circuit rejected that argument. “The sports event contracts were not ‘swaps’ because they were sports bets,” the court said in its opinion against Kalshi.
Legal experts have widely expected that the question of sports-related event contracts, and whether state gaming regulators or the CFTC has the right to regulate them, will eventually reach the Supreme Court.
That now appears very likely, as the ninth circuit’s decision contradicts a ruling from the Third Circuit Court of Appeals in early April. In that case, the third circuit ruled that only the CFTC has the jurisdiction to regulate sports-related event contracts.

“This is a classic circuit split,” said Joshua Mitts, a professor at Columbia Law School. Circuit splits are when federal appeals courts rule differently on the same topic. “Ultimately, this is the kind of legal controversy or legal difference of opinion which will make its way to the Supreme Court.”
Kalshi, Crypto.com, Robinhood, the CFTC and the Nevada Attorney General’s office did not immediately respond to requests for comment.
Meanwhile, shares of two online sportsbooks, DraftKings and Flutter Entertainment — the parent company of FanDuel — rose in response to the ruling. Both stocks have been hit in the last year over concerns of prediction markets disrupting the industry, and have rushed to get their own prediction market exchanges online.
DraftKings jumped 7%, while Flutter was up more than 6%.
Disclosure: CNBC and Kalshi have a commercial relationship that includes customer acquisition and a minority investment.
