Ninth Circuit Upholds Nevada Authority Over Kalshi Prediction Market Contracts

The U.S. Court of Appeals for the Ninth Circuit issued a unanimous decision in August 2026 that denied prediction market operator Kalshi an injunction against Nevada gaming regulators, and the ruling determined that the company's sports event contracts fall under state gambling laws rather than qualifying as swaps protected by the Commodity Exchange Act. Observers note the court rejected Kalshi's arguments for federal preemption, which means Nevada and similar states retain the ability to require licensing and regulatory oversight for these activities.

This outcome stems from a lawsuit where Kalshi sought to operate without state approval by classifying its offerings as financial instruments, yet the Ninth Circuit found the contracts involve sports betting elements that trigger Nevada's existing framework for gambling enforcement. The decision emphasizes that these products do not meet the definition of swaps under federal commodity rules, and it leaves room for state-level control in jurisdictions that choose to apply their laws.

Background on the Dispute and Kalshi's Position

Kalshi had positioned its event contracts as tools for hedging risks or speculating on outcomes, and the company argued that federal law under the Commodity Exchange Act should override state restrictions, yet Nevada regulators viewed the sports-focused contracts as forms of betting that demand local licensing. The Ninth Circuit examined the structure of these contracts and concluded they constitute gambling because they depend on the occurrence of specific athletic events rather than serving as standard derivative instruments in commodity markets.

State officials in Nevada maintained that allowing unlicensed operation would undermine their established system for overseeing gaming activities, and the court agreed that preemption does not apply when the contracts align more closely with traditional sports wagering. This stance aligns with how other states have approached similar platforms, creating a consistent expectation that operators must comply with local rules where they offer such products.

Key Elements of the Ninth Circuit Ruling

The appellate panel reviewed Kalshi's request for injunctive relief and found insufficient grounds to block enforcement actions, while it clarified that the contracts in question involve wagers on sports results which fall outside the swaps category protected by federal statute. The court highlighted distinctions between these offerings and legitimate commodity swaps, noting that the primary purpose centers on event outcomes rather than financial hedging mechanisms typically associated with derivatives trading.

Evidence presented during proceedings showed that Kalshi's contracts allow participants to take positions on game results, and this feature led the judges to classify them as sports betting activities subject to state regulation. The unanimous opinion reinforces that federal commodity laws do not automatically preempt state authority in this area, and it permits Nevada to proceed with its oversight requirements without federal interference at this stage.

Circuit Split Emerges With Third Circuit Precedent

A prior ruling from the Third Circuit in New Jersey had favored Kalshi by recognizing certain contracts as swaps eligible for federal protection, and this created a split between circuits that now sets up potential review by the U.S. Supreme Court. The Ninth Circuit explicitly diverged from that earlier decision, and its analysis focused on the sports-specific nature of the contracts as the determining factor that brings them under state gambling statutes.

Differences in how the two circuits interpreted the Commodity Exchange Act definitions have left operators facing varying legal standards depending on location, and this inconsistency may prompt higher court intervention to establish uniform national guidance. Legal observers point out that such splits often lead to Supreme Court consideration when they affect multi-state business operations in emerging financial and gaming sectors.

Implications for State Regulation and Market Operators

The ruling allows Nevada to enforce its licensing and compliance rules on platforms like Kalshi, and similar states gain clarity that they can apply existing gaming laws to event contracts involving sports outcomes. Regulators in multiple jurisdictions now have precedent to require oversight, which means operators must navigate state-by-state approvals rather than relying solely on federal commodity status for nationwide access.

Industry participants note that this decision affects how prediction markets structure their products going forward, and it may encourage companies to adjust contract terms or seek separate state licenses to continue operations in regulated markets. The outcome also underscores the role of state gaming commissions in determining what qualifies as betting versus financial instruments, and it places the burden on operators to demonstrate compliance where sports events form the basis of the contracts.

Potential Path to Supreme Court Review

Because the Ninth Circuit decision conflicts with the Third Circuit's earlier holding, Kalshi or other affected parties could petition the Supreme Court for review, and such a step would address the broader question of federal preemption in prediction market activities. The circuit split introduces uncertainty for businesses operating across multiple regions, and a high court ruling could resolve whether states retain authority over sports event contracts or if federal commodity rules provide broader protection.

Proceedings at the appellate level concluded without granting the requested injunction, and this leaves the case positioned for further appeals if the parties choose to pursue them. The August 2026 timing aligns with ongoing developments in how courts balance state gambling interests against federal financial regulations, and additional litigation could clarify boundaries in this evolving area.

Conclusion

The Ninth Circuit's unanimous ruling establishes that Kalshi's sports event contracts do not qualify for federal swaps protection under the Commodity Exchange Act, and it permits Nevada regulators to apply state licensing requirements without preemption. This creates a split with the Third Circuit decision from New Jersey, and it opens the possibility of Supreme Court involvement to settle differing interpretations across circuits. Operators in the prediction market space now face clearer expectations that sports-related contracts fall under state gambling oversight in jurisdictions like Nevada, while the legal landscape continues to develop through additional cases and potential higher court review.
