Ninth Circuit Rejects Kalshi in Nevada Dispute
The U.S. Ninth Circuit Court of Appeals dealt a decisive blow to Kalshi on Friday, upholding Nevada’s ban on the exchange’s event contracts. The ruling, which stems from Nevada’s 2023 cease-and-desist order, marks a significant setback for the prediction market operator. The court agreed with state regulators that Kalshi’s contracts functioned as unlicensed gaming, not “insurance” or “investment” instruments.
For the broader event-contract sector, the loss is more than a legal footnote. Traders immediately repriced the likelihood that the U.S. Supreme Court will intervene, with prediction market odds of a grant of certiorari jumping past 60% by Friday afternoon. The Ninth Circuit’s split with other federal circuits—and its explicit rejection of Kalshi’s federal preemption argument—creates the exact circuit conflict the High Court often looks for.
Market Impact
The ruling reinforces that state-level gambling oversight remains the largest regulatory hurdle for prediction platforms. For traders and investors, the key takeaway is jurisdictional risk: what is legal in one state can vanish in another. Kalshi and rival platforms have leaned heavily on CFTC approval as a shield, but this decision says that shield has limits.
That uncertainty is already being priced into volatility across event-contract markets, particularly for state-specific political and sports-related offerings. A potential Supreme Court review could take 18 to 24 months, meaning prolonged legal ambiguity for any platform eyeing expansion in the U.S. Meanwhile, offshore and regulated alternatives—including markets available via platforms like Jeetcity—may see increased attention as traders look for stable venues less exposed to U.S. federal-state legal ping-pong.
The ruling also affects how prediction markets are categorized. If the Supreme Court sides with Nevada, more states could follow with their own restrictions. If it sides with Kalshi, we could see a nationwide opening. For now, the smart play for active traders is to monitor the cert petition timeline and avoid concentrating positions in single-state event contracts.
What to Watch
- Supreme Court cert petition: Kalshi has 90 days to file. A grant is likely in early 2026 if it comes at all.
- CFTC response: Watch for any updated guidance on event contracts following the circuit split.
- State-level copycats: Nevada’s win may encourage other states to test their own bans, accelerating legal fragmentation.
- Platform shifts: Traders may rotate liquidity toward non-U.S. or CFTC-supervised markets while the legal picture clears.
