CFTC swap proposal faces Supreme Court review with four seats empty

Mike Selig is running a five-seat federal agency from a single chair. The CFTC's October 9 rulemaking — an interim final rule carving casino wagers out of the swap definition, paired with a proposed rule pulling sports, political, and weather event contracts firmly inside it — is the most consequential jurisdictional claim the agency has made in the prediction markets era. It is also being made by one person. The White House has not nominated anyone to fill the four remaining commissioner seats.

That is not a procedural footnote. It is the structural fact around which everything else in this regulatory fight turns.

The Commodity Exchange Act vests rulemaking authority in the Commission. A Commission with five members has internal friction — dissents, competing readings of statutory text, votes that force the chair to justify a position on the record. A Commission with one member has a chair who is also the majority, the minority, and the whole of the deliberative body at once. When the Supreme Court, now holding a petition from several state attorneys general, evaluates the CFTC's formal position on event contracts, it will be evaluating a rule produced without that internal discipline.

That matters because the legal question the Court would resolve is genuinely hard. Whether event contracts qualify as swaps under Dodd-Frank, and whether that classification preempts state gambling authority under the Supremacy Clause, turns on statutory construction that reasonable lawyers have read differently — federal appellate courts have already gone both ways. The CFTC's rulemaking gives Selig something to point to: the agency has not merely argued its position in litigation, it has begun implementing it. That is a meaningful posture before a reviewing court. Chevron deference is gone after Loper Bright, but an agency's contemporaneous interpretation of its own enabling statute still carries weight in the analysis, particularly when the statute is ambiguous at the edges.

The edges here are the whole case. The interim final rule's carve-out for casino wagers reads as a deliberate attempt to draw the distinction the states have been refusing to accept — that a sports event contract traded on a CFTC-registered exchange is categorically different from a sportsbook wager, even when both resolve on the same game. The Seminole Tribe's lawsuit against DraftKings, now in Florida state court, is premised on exactly the opposite reading: that the functional identity of the two products should govern, not the regulatory wrapper around them.

The consensus read in this space treats the CFTC's rulemaking as strengthening Selig's litigation position substantially. I think that underweights a specific vulnerability. A rule issued by a sole commissioner, on a 30-day comment period, covering a $1.5 billion monthly market, will face administrative law challenge independent of the substantive statutory question. The brevity of that comment period and the absence of collegial deliberation are exactly the procedural facts a reviewing court would examine under the APA's arbitrary-and-capricious standard. The agency's legal theory may be correct and its rulemaking still be set aside on process grounds. Those are two different proceedings with two different outcomes, and conflating them overstates how much the October 9 rules actually resolve.

Kalshi and Polymarket have active markets on the Supreme Court petition. The question those markets are pricing is whether the Court grants cert. The more instructive question — one no market has yet cleanly structured — is whether the CFTC's rulemaking survives APA review long enough to matter to the Court's analysis at all.
