Nevada court blocks Coinbase prediction markets, challenges federal oversight claims
Summary
A Nevada state court granted a preliminary injunction on 26 March barring Coinbase from offering event-based prediction contracts in Nevada. The order follows a February temporary restraining order and centres on Coinbase’s partnership with Kalshi, a regulated exchange for contracts tied to real-world events such as sports, elections and entertainment.
The court rejected the argument that the Commodity Exchange Act (CEA) vests exclusive jurisdiction in the Commodity Futures Trading Commission, finding that the CEA does not pre-empt Nevada’s gambling laws as applied to these contracts. Coinbase has 60 days to implement technological changes and, in the interim, will screen users by residency to comply with the order.
Key Points
- On 26 March the First Judicial District Court of Nevada issued a preliminary injunction stopping Coinbase from offering event-based prediction contracts in Nevada.
- The dispute concerns Coinbase’s tie-up with Kalshi, which lists contracts tied to real-world outcomes (sports, elections, entertainment).
- The court held the Commodity Exchange Act does not clearly pre‑empt state gambling laws for these products, rejecting claims of exclusive CFTC authority.
- Coinbase must make technical adjustments within 60 days and will screen users by residency during the interim period.
- Nevada recently won a similar injunction against Kalshi itself, signalling an active state-level enforcement push.
- Other states and courts are split: some rulings favour state oversight (Nevada, Massachusetts), while Tennessee recently blocked state enforcement against Kalshi.
- Prediction markets have grown quickly (Blask reported a 256% performance index increase in 2025), driven by the 2024 US election and added sports contracts.
- With divergent rulings across jurisdictions, the question of federal pre-emption could ultimately reach the US Supreme Court.
Context and relevance
This ruling is part of a broader national tussle over whether prediction markets are financial instruments governed federally or gambling activities regulated by states. For exchanges, fintech firms and regulators, the outcome will shape licensing, product design and market access in the US. Operators expanding beyond crypto (like Coinbase) into event contracts face immediate legal and operational risk as states press their gaming statutes.
Author style
Punchy — this is a must-watch story for anyone tracking regulation of new financial products. The ruling has real teeth and could reshape how prediction markets operate in the US.
Why should I read this?
Quick take: Nevada just put the brakes on Coinbase’s prediction bets and said ‘not so fast’ to the idea that only the feds can decide. If you work in crypto, betting, compliance or regulation, this affects whether these products can be offered state-by-state or will be forced into a federal framework — and it could end up at the Supreme Court. Definitely worth a skim if you want to stay ahead of where the rules are headed.
