CFTC swap proposal puts Selig alone against 51 state attorneys general

Mike Selig issued two rules on October 9 and signed his name to both of them. One took immediate effect. The other opened a thirty-day comment window. Between those two actions, the sole commissioner of the Commodity Futures Trading Commission — the agency has four empty seats and no nominated replacements — formally declared that event contracts are swaps, that swaps belong to him, and that the states can object in writing if they like.

The audacity of the position is worth sitting with before assessing its legal durability.

Selig's interim final rule carves casino-style wagering out of the swap definition, which is designed to preempt the argument that the CFTC is claiming jurisdiction over everything gambling-adjacent. His proposed rule then draws the circle back inward: sports, politics, climate, cultural events — anything trading on platforms like Kalshi or Polymarket — falls within the Commodity Exchange Act's swap definition and therefore within exclusive federal oversight. The comment period is thirty days, which is brief for a rule this consequential and almost certainly intentional.

The legal architecture Selig is building on is real but contested. Section 7a-3 of the Commodity Exchange Act does grant the CFTC broad authority over swap transactions, and Dodd-Frank's preemption provisions are explicit: where federal swap regulation applies, state law yields. If event contracts are swaps, the states lose. That is the clean version of the argument, and it is not frivolous.

The problem is that several federal appellate courts have already declined to accept the clean version. The split is now deep enough that state attorneys general have petitioned the Supreme Court to resolve it. The NFL has filed a brief supporting state oversight. The American Gaming Association has backed New Jersey's position against Kalshi. Selig is not winning the argument in court at the rate he is winning it on the Federal Register.

His response to that gap is the rules themselves. When the Commission eventually has to defend its position before a reviewing court — or before the Supreme Court, if it gets there — Selig will be able to show a formal regulatory record: an interim final rule already in operation, a proposed rule with a comment period, and an agency that has treated event contracts as swaps consistently and on the record. Administrative law gives some deference to an agency's interpretation of its own statute. Selig is building the factual predicate for that deference, even as the courts have been skeptical.

I think this is weaker than it looks. Chevron deference was already constrained before the current Court, and the justices who are likely to hear this case have shown no appetite for expanding agency authority in genuinely contested domains. An agency with one commissioner, no confirmed colleagues, and a rulemaking history built in the middle of active litigation reads differently to a reviewing court than a fully constituted commission acting through deliberate process. The procedural posture matters. It always has.

The standard a reviewing court will apply is whether the CFTC's swap definition is consistent with the text of the Commodity Exchange Act as amended by Dodd-Frank, and whether the agency's preemption claim survives the presumption against displacing state police power. Those are not the same question, and Selig has to win both.
