Kalshi sports contracts swap ruling: Ninth Circuit says contracts aren’t swaps, splitting with Third Circuit

The Ninth Circuit issued its opinion on Friday, delivering a decisive Kalshi sports contracts swap ruling that the contracts do not meet the Commodity Exchange Act’s definition of a swap. By classifying them as non-swap products, the court cleared the way for Nevada to enforce its gaming statutes against the prediction-market platform. This ruling stands in stark contrast to the Third Circuit’s earlier decision, which treated identical contracts in New Jersey as swaps and therefore under exclusive CFTC oversight. The split creates immediate regulatory uncertainty for operators that sell event-based derivatives across state lines.

Ninth Circuit ruling on Kalshi sports contracts: legal analysis

The dispute centers on whether a contract tied to the outcome of a sporting event qualifies as a “swap” under the CEA. The act defines a swap as an agreement dependent on “the occurrence, non-occurrence, or the extent of the occurrence of an event.” Kalshi argued that a contract betting on, for example, the winner of the Super Bowl satisfies that language, which would place the product under CFTC jurisdiction and shield it from state gaming laws.

The Ninth Circuit rejected that reading, emphasizing a textual distinction between an event’s occurrence and its outcome. “Whether the Super Bowl happens is the occurrence of an event; whether a particular team wins is the outcome of an event,” the opinion wrote, warning that Kalshi’s broader interpretation “knows no limiting principle because anything could be defined as an event.” By drawing that line, the court concluded the contracts are not swaps, opening them to state regulation.

Implications for Nevada gaming enforcement

Nevada law prohibits event contracts that involve, relate to, or reference gaming activities. The panel relied on 17 C.F.R. §40.11(a) to find that Kalshi’s self-certified sports contracts violated this prohibition. The court held that self-certification, which allows an exchange to launch a product without prior CFTC approval, is unlawful when the contract is linked to gaming. As a result, Nevada can now require Kalshi to obtain a gaming license, pay licensing fees, and submit to compliance audits before offering the contracts to residents.

Circuit split and potential Supreme Court review

In New Jersey, the Third Circuit previously held that the same class of contracts are swaps, granting the CFTC exclusive authority and effectively insulating the product from state enforcement. The Ninth Circuit’s contrary view creates a geographic regulatory bifurcation: Kalshi’s platform will be subject to Nevada’s gaming regime while remaining federally pre-empted in New Jersey. This divergence raises the prospect of a petition for certiorari, as industry groups and the parties may seek a uniform rule from the Supreme Court.

Impact on institutional capital allocation

The decision forces institutional investors to reassess exposure to state-level enforcement risk. Nevada’s gaming authority could impose licensing costs, compliance burdens, and wagering limits that affect liquidity provision and market-making profitability. Conversely, platforms operating in Third Circuit jurisdictions may continue to enjoy a federal shield, creating an uneven competitive field. Investors tracking aggregate protocol value have already noted a modest decline in total value locked for prediction-market protocols following the ruling.

For market participants tracking protocol value, the ruling may shift capital toward platforms that either avoid event-based contracts or secure explicit CFTC approval. The protocol value tracker on the protocol value tracker shows a modest decline in total value locked for prediction-market protocols after the announcement, reflecting heightened risk perception among investors.

How operators can adapt to the new landscape

Kalshi will likely need to restructure its product offering in Nevada. Options include:

1. Re-classifying contracts as non-gaming events (e.g., weather or macro-economic outcomes).
2. Obtaining a Nevada gaming license, which can take several months and require extensive compliance infrastructure.
3. Withdrawing the sports contracts from Nevada entirely and focusing on jurisdictions where the contracts remain classified as swaps. Each path entails significant operational overhead. Competitors such as Polymarket, which already operate under a hybrid regulatory model, may see an influx of users seeking a more certain legal environment.

Broader regulatory landscape for prediction markets

The split decision highlights a tension between innovative fintech products and legacy regulatory frameworks. As decentralized finance blurs the lines between traditional derivatives and novel event contracts, courts are forced to interpret statutes that predate digital assets. The Ninth Circuit’s textualist approach suggests courts may favor narrow, literal readings that preserve state authority, while appellate courts in other circuits may continue to lean on the CFTC’s expertise.

If the Supreme Court eventually steps in, its ruling could either cement a unified federal pre-emption doctrine—favoring a national market for event contracts—or affirm the ability of states to regulate gaming-related derivatives, potentially fragmenting the market and prompting a wave of jurisdiction-specific compliance solutions.

What to watch next

• Supreme Court petition – Both Kalshi and industry groups have indicated intent to seek certiorari, making a high-court decision a realistic near-term outcome.
• CFTC guidance – The agency may issue clarifying guidance on the scope of §40.11(a) and the permissibility of self-certified gaming contracts.
• State legislative activity – Nevada could amend its gaming code to explicitly address prediction markets, while other states may follow suit.
• Capital migration – Track shifts in TVL across prediction-market protocols on the protocol value tracker as investors reallocate to platforms with clearer regulatory status.
• Operational adjustments – Monitor how Kalshi and peers restructure product offerings, obtain licenses, or exit certain jurisdictions.

Kalshi Ruling Redraws Market Jurisdiction

The Ninth Circuit’s Kalshi sports contracts swap ruling reshapes the regulatory map for prediction markets, granting Nevada the ability to enforce its gaming laws where previously the CFTC held exclusive sway. The split with the Third Circuit sets the stage for a potential Supreme Court showdown, while operators scramble to adapt product strategies and compliance frameworks. Stakeholders should monitor regulatory filings, CFTC statements, and state legislative proposals to gauge how the market will evolve in the coming months.
