CFTC Prediction Market Rules: A Definition Cannot Settle Preemption

The CFTC Moves to Define Event Contracts as Swaps

The CFTC proposed on Friday, October 9, 2026 to define "swap" to include event contracts based on sports, politics, cultural and weather-related events. The Notice of Proposed Rulemaking, titled "Further Definition of 'Swap' – Inclusions" (RIN 3038-AF82), is the agency's most direct attempt to place prediction markets under its "exclusive jurisdiction" and beyond state reach, as Law360 reported.

But here is the part the headlines are missing. The Sixth Circuit has already held, in the alternative, that the Commodity Exchange Act does not preempt Ohio and Tennessee gambling laws even if these contracts are swaps. A definitional rule answers the question the Sixth Circuit said did not matter.

Here is what happened, why it matters, and what operators should do about it.

Two Actions, One Day, Two Very Different Legal Statuses

The CFTC released two documents on October 9. The first is the swap-definition proposal. It is a proposal, not law. Comments are due 30 days after Federal Register publication, and as of this writing no publication date has been set, according to the proposal text.

The second is a companion interim final rule (RIN 3038-AF81) that codifies the exclusion of casino-style gambling products, including sportsbook wagers and casino games, from the "swap" definition. It is effective upon Federal Register publication, with comments due 30 days after that.

The distinction that matters. The interim rule draws the line between what the CFTC wants and what it concedes to states. Sports event contracts go in. Sportsbook wagers stay out. Every product team now has to know which side of that line its contract sits on.

This is also separate from the CFTC's June 10, 2026 proposal on public interest determinations (RIN 3038-AF65), which amends Part 40 and whose comments closed July 27, 2026. Conflating the two is an easy mistake and a costly one in a comment letter.

Why a Rule Cannot Resolve a Circuit Split

The proposal responds to a widening split. The Third Circuit ruled 2-1 for Kalshi on April 6, 2026 in KalshiEX v. Flaherty. The Ninth Circuit ruled unanimously against Kalshi in a Nevada case on August 28, 2026. The Sixth Circuit ruled unanimously against Kalshi on September 25, 2026, as CNBC reported.

Chairman Michael S. Selig said event contracts "are commodity derivatives squarely within the CFTC's regulatory remit" and "within the agency's exclusive jurisdiction." That is a statement of position. Preemption is a question of congressional intent that courts decide.

The rulemaking-process reality.

• Timing is slow. Both actions reached White House review on September 28, 2026, per CDC Gaming. A final swap rule still requires comment, review and adoption.
• The Supreme Court may move first. New Jersey's cert petition, No. 26-299, is pending, with Kalshi's response due November 9, 2026, per this docket summary. Review has not been granted.
• Litigation over the rule itself is likely. A final rule faces its own challenges.

The message is clear. Operators should not assume federal exclusivity in 2027 business plans.

What Your Leadership Team Should Decide This Quarter

The board-level question is not whether the CFTC wins. It is whether your company can operate profitably if it loses in some circuits.

• Map product exposure by circuit. State-by-state availability in Sixth and Ninth Circuit states carries real consequences for revenue forecasts.
• Classify every contract against the interim rule. Anything resembling a sportsbook wager or casino game is now expressly outside the swap definition.
• Decide whether to comment. The 30-day window opens on publication; assign an owner today so the letter is not drafted in a week.
• Revisit investor disclosures. Fund managers and venture investors holding prediction market exposure should describe the split accurately, not cite federal exclusivity as settled.

Ask your general counsel for a jurisdictional matrix that updates as the circuit litigation and the New Jersey cert petition move.
