Kalshi Ruling Puts CFTC Prediction Rules at Risk Today

A federal appeals court panel on Aug. 28 delivered a key preliminary ruling in the dispute between prediction-market operator Kalshi and Nevada gaming regulators, concluding Kalshi is unlikely to show that Nevada’s enforcement of sports-event contracts is preempted by federal commodities law. The decision preserves state-level enforcement against certain event contracts and raises new questions about the reach of Commodity Futures Trading Commission (CFTC) rulemaking for prediction markets and event contracts.

What the Ninth Circuit decided

The Ninth Circuit denied Kalshi’s request for a preliminary injunction that would have blocked Nevada from applying its gaming laws to the platform’s sports-event contracts. The panel found Kalshi had not shown it was likely to succeed on the argument that its offerings qualify as “swaps” under the Commodity Exchange Act (CEA), which would displace state gambling rules when traded on a CFTC-regulated designated contract market.

Preemption and statutory interpretation

Judges reasoned that Kalshi’s sports contracts function more like traditional sports bets than derivatives that fall squarely within the CEA’s definition of swaps. The court rejected Kalshi’s express, conflict and field-preemption claims at this early stage, saying the company did not demonstrate a strong likelihood federal law overrides Nevada’s regulatory authority. The opinion emphasized limits on interpreting federal statutes so broadly that they would swallow long-standing state oversight of gambling and sports wagering.

Major-questions doctrine and rulemaking implications

Although the panel raised concerns related to the major-questions doctrine — which limits agency power when statutes lack a clear statement of congressional intent for sweeping regulatory authority — it stopped short of invalidating the CFTC’s proposed event-contract rules. The court’s language suggested a skeptical view of expansive federal authority over gaming-related contracts, but it did not hold that the doctrine categorically bars CFTC regulation of prediction markets or event contracts.

Expert reaction

Some gaming-law specialists said the ruling makes future Administrative Procedure Act (APA) challenges to any finalized CFTC rule more likely. Opponents could argue a final rule exceeds statutory authority or is procedurally defective. Other observers, including technologists familiar with blockchain-based markets, warned the opinion should not be read as a definitive curb on federal regulation: Congress could still craft clearer statutory authority for nationwide oversight of exchange-traded contracts without wholly preempting state gaming laws.

CFTC’s proposal and the practical stakes

In June the CFTC proposed amending Rule 40.11 to set a 90-day review process for event contracts and to clarify when a contract “involves” enumerated activities — including gaming, terrorism, assassination, war, or other unlawful conduct. The agency invited public comment through July 27 and may revise, finalize, or withdraw the proposal after review. If finalized, a rule that asserts broad authority over gaming-related markets could face APA litigation over statutory authority and agency reasoning.

Circuit split raises Supreme Court possibility

The Ninth Circuit’s ruling conflicts with a Third Circuit decision that previously favored Kalshi in litigation with New Jersey. That split across circuits increases the odds that the Supreme Court could eventually weigh in on whether federal derivatives regulation displaces state gambling control for prediction markets and sports contracts. Neither Kalshi nor Nevada had immediately confirmed next steps such as a petition for rehearing or a Supreme Court appeal, but the jurisdictional split makes appellate escalation plausible.

Immediate consequences for Nevada and prediction markets

For now, Nevada regulators can continue to enforce state gaming laws against Kalshi’s sports-event contracts while the election-related claims in the case are sent back to district court. The decision leaves the CFTC’s proposed rulemaking intact but injects additional legal arguments that opponents could raise if the agency adopts a final rule claiming broad reach into sports betting and prediction markets.

Implications for crypto and blockchain markets

The outcome matters for blockchain and crypto-native prediction markets that design event contracts and derivatives on decentralized exchanges or centralized platforms. If federal authorities ultimately assert wide jurisdiction, operators may seek CFTC registration or adapt products to avoid crossing into regulated categories. Conversely, if states retain authority, local licensing and gaming compliance will continue to shape where and how crypto prediction markets operate.

What’s next

The legal battle over Kalshi’s event contracts is far from over. The Ninth Circuit’s opinion narrows Kalshi’s path to immediate relief in Nevada while preserving avenues for future challenges to CFTC rulemaking under the APA. Market participants, regulators and legal teams will watch subsequent filings closely — especially any moves toward the Supreme Court — because the ruling affects the regulatory environment for prediction markets, sports betting, and related crypto products across multiple jurisdictions.

In short: Nevada can enforce its gaming laws against Kalshi’s sports contracts for now, the CFTC proposal remains pending, and the split between federal appeals courts increases the likelihood of high-stakes litigation that will shape the future of prediction-market regulation.
