A U.S. appeals court has allowed Nevada to continue applying state gaming oversight to Kalshi’s sports event contracts. The decision does more than restrict one platform in one state: it deepens a federal circuit split over whether prediction markets are primarily federally regulated derivatives venues or state-regulated gambling products.

What the court decided

The Ninth U.S. Circuit Court of Appeals concluded that Kalshi was unlikely to show that the Commodity Exchange Act displaced Nevada’s gaming rules for sports contracts. The panel therefore declined to restore the injunction that had shielded the platform from state enforcement. The dispute over election-related contracts returns to the lower court for further consideration.

The ruling contrasts with a Third Circuit decision involving New Jersey, where the court prevented the state from regulating Kalshi. When federal appellate courts reach different conclusions about the same statutory boundary, the probability of Supreme Court review rises because national platforms cannot operate cleanly under conflicting regional rules.

The classification problem

Prediction markets describe contracts whose payoff depends on an event: an election outcome, an economic release or a sports result. Federally regulated designated contract markets argue that these instruments fall within commodities law and CFTC oversight. States respond that some contracts are economically indistinguishable from sports wagering and therefore remain within traditional gaming authority.

The practical distinction cannot be solved by labels alone. Regulators and courts will examine the underlying event, customer experience, market structure, settlement mechanics and public-interest exclusions. A contract can use exchange technology and still raise the same policy concerns as a bet; conversely, an event contract can also produce information useful for risk management.

Why the circuit split matters

• Product availability: platforms may need state-by-state restrictions even while operating under federal registration.
• Liquidity fragmentation: excluding users by jurisdiction can reduce depth and distort prices.
• Compliance costs: legal classification becomes a product-design constraint rather than a background issue.
• Counterparty expectations: users need clarity on which regulator protects market integrity and customer funds.
• Innovation risk: unresolved jurisdiction encourages aggressive launches followed by injunctions and abrupt market closures.

What a durable framework needs

A workable U.S. framework should separate event categories instead of treating every contract identically. Economic and weather hedges have different public-policy characteristics from sports contests. Election markets raise distinct manipulation and civic-integrity concerns. Congress or the Supreme Court may ultimately need to clarify the boundary between exclusive federal jurisdiction and preserved state police powers.

For investors and operators, the immediate lesson is that federal registration is not yet a complete shield against state enforcement. The value of a prediction-market platform therefore depends not only on trading volume and technology, but also on the durability of its jurisdictional model.
