CFTC Interim Final Rule Splits Casino Bets From Event Swaps

The CFTC interim final rule published on Friday, October 9, 2026, codifies the agency's position that casino-style gambling products, including sportsbook wagers and casino games, are not swaps. In a companion step, the Commodity Futures Trading Commission proposed expressly defining event contracts, including those based on sports, politics, culture and weather, as swaps, according to its press releases. Together, the two actions are designed to cement federal authority over prediction markets as states press their own claims in court.

What happened

The interim final rule takes effect immediately upon publication in the Federal Register, with written comments due within 30 days of publication. "Casino-style gambling products are not derivatives," said Chairman Michael S. Selig. "Just as the CFTC has done with respect to other products historically regulated by the states, the Commission today provides clarity regarding the limits of its regulatory remit by codifying the exclusion of casino-style gambling products from the 'swap' definition."

The second action is a notice of proposed rulemaking. It would further define "swap" to include event contracts, which the agency said are "commonly known to the trade as swaps," and proposes to resolve any ambiguity about them, according to the CFTC's release. "These products are commodity derivatives squarely within the CFTC's regulatory remit under the Commodity Exchange Act and are within the agency's exclusive jurisdiction," Selig said. Comments on the proposal are also due within 30 days of Federal Register publication.

CoinDesk reported that the actions had been submitted for White House review less than two weeks earlier, an unusually quick process. We covered that submission in our report on the CFTC event contracts swap definition; Friday's publication turns it into policy and a formal proposal.

Why it matters

The CFTC interim final rule answers a specific argument from the states. Several states are suing over sports contracts on platforms such as Kalshi and Polymarket, and many have accused operators of running illegal gambling. Federal appellate decisions have gone both ways, with one ruling against the states and two supporting them, CoinDesk said. States and former federal officials involved in drafting the relevant laws have filed views with the U.S. Supreme Court, which has been asked to resolve the dispute.

"We view this interim final rule as designed to improve the agency's position in court as the states are arguing that the CFTC's definition of a swap would make federally illegal any wager made at a state or tribal casino or sportsbook," TD Cowen policy analyst Jaret Seiberg wrote in a note, according to CoinDesk. "Whether this actually works is a different question."

According to CoinDesk, the agency is trying to define which kinds of sports wagering are not swaps while maintaining that event contracts still meet the statutory definition. The "interim final" label matters: the rule becomes immediate policy but stays open to public input as it is implemented, whereas the event-contract definition must go through notice and comment before it can be finalized.

The logic is to concede ground the agency never wanted, traditional casino and sportsbook betting, in order to defend the ground it does want, exchange-traded event contracts. If casino wagers are explicitly outside the swap definition, states lose one of their strongest arguments that the CFTC's reading would sweep in their entire gambling industry. Companies such as Kalshi are on the same side as the agency, seeking to establish the CFTC as their sole regulator. The NFL has taken the opposite view in its Supreme Court filing, as we reported in NFL prediction markets brief.

Governance is part of the story. Selig is the lone commissioner on what is meant to be a five-member commission and can set policy on his own, CoinDesk noted, and President Donald Trump has so far declined to name additional commissioners.

What's next

The CFTC interim final rule is in force once published, while the event-contract definition remains a proposal with a relatively short 30-day comment window. Expect heavy comment traffic from states, tribal gaming interests, sports leagues and exchanges. If the Supreme Court takes up the dispute, the agency will be able to point to formal rules rather than interpretations, though, as Seiberg noted, whether that persuades the courts is uncertain. A final event-contract rule after the comment period would be the next milestone. This article is for information only and is not legal or investment advice.
