CFTC prediction markets rule: event contracts would count as swaps, casino wagers excluded from definition

The Commodity Futures Trading Commission announced on October 9, 2026 two actions that re-draw the line around what counts as a swap, and they push in opposite directions. A proposed rule would treat event contracts based on sports, politics, cultural and weather-related events as swaps subject to agency oversight, while a companion interim rule codifies that casino-style gambling products, including sportsbook wagers and casino games, fall outside the swap definition.

Neither action is law yet, and the distinction matters for what prediction-market venues may list. The Notice of Proposed Rulemaking, announced in the CFTC's press release 9310-26, would pull event contracts into the swap definition by expressly naming them, bringing more federal oversight and listing implications to Kalshi, Polymarket and other venues. The Interim Final Rule, in the CFTC's press release 9309-26, keeps licensed sportsbook and casino wagers that are not traded on a board of trade or other multilateral market outside the definition, giving sportsbook operators an explicit carve-out.

Chairman Michael S. Selig was direct about the exclusion. "Casino-style gambling products are not derivatives," he said in the release . The interim rule, he added, provides "clarity regarding the limits of its regulatory remit by codifying the exclusion of casino-style gambling products from the 'swap' definition."

The two actions are the agency's answer to courts that reached opposite conclusions about event contracts. The Sixth and Ninth Circuits sided with states and treated a sports event contract like a sportsbook wager, on the logic that if one is a swap, the other must be too. The Third Circuit's April ruling in Kalshi's favor held that Congress gave the CFTC power to "further define" swaps and pointed the agency toward the rulemaking route. The CFTC called the Sixth and Ninth premise "erroneous" and said the interim rule "implements the Third Circuit's suggested approach" by drawing a boundary between event contracts and casino-style gambling.

What would change, and who it touches

Had the two actions already taken effect, the near-term picture for prediction markets would look different. On the bear side, a finalized proposal making event contracts swaps would hand the CFTC more authority over contracts that currently operate in the space between commodity law and state gambling regulation. Venues would face questions about which contracts count, how they are cleared and reported, and whether listing a political or weather contract now triggers swap documentation and record-keeping obligations. For venues that have leaned on the argument that their products are not futures, not swaps and not wagers, a determination that they are swaps removes a key legal pillar.

On the bull side, the pair offers something the industry has said it wants: a defined boundary. The interim rule's explicit exclusion of casino-style wagers, if it becomes effective, protects the sportsbook channel from being swept into derivatives regulation, and the proposed carve of event contracts into the swap definition at least answers the question of where the line sits instead of leaving it to be settled case by case. Clarity, even unwelcome clarity, tends to be read favorably by venues that have spent years litigating their status.

The pending Federal Register status

Neither document had appeared in the Federal Register as of early checks on October 10, so the procedural clock has not started. The interim rule becomes effective "immediately upon publication in the Federal Register," and written comments are due via Regulations.gov within 30 days of that publication. Comments on the proposed rule are also due within 30 days of its Federal Register appearance. Until either document is published, readers should treat the interim rule exclusion as announced but not yet operative, and the event-contract inclusion as a proposal rather than a live rule.

The immediate catalyst to watch is Federal Register publication of either document, which starts both comment clocks and makes the interim rule effective. Until then, the paired actions define the direction of travel: the CFTC appears set to treat event contracts as swaps while leaving casino-style wagers to the states that traditionally regulate them. For prediction-market venues, the practical question is not whether the boundary is favorable, but when it becomes binding and how many contracts sit on which side of it.
