CFTC moves to implement casino products rule before court decision

CFTC interim rule on casino products could take effect before courts rule

The interim final rule arrived at the White House on September 28, and almost nobody noticed the mechanism.

Everyone has been watching the swap definition — RIN 3038-AF82, the proposed rule that would explicitly classify event contracts as swaps and hand the CFTC exclusive jurisdiction over platforms like Kalshi and Polymarket. That rule goes to public comment. It will take months. The Supreme Court may well rule before it becomes final. That is the fight people are pricing.

The rule they are not pricing is RIN 3038-AF81.

That second measure is an interim final rule, and the distinction matters more than the coverage suggests. Interim final rules are an unusual instrument: an agency publishes them, they take effect, and public comment runs concurrently rather than before. The CFTC has used this mechanism to carve casino-style gambling products out of the swap definition — meaning the exclusion could become operative the moment the White House finishes its review, regardless of what any court decides in the meantime.

The reporting frames this as a single regulatory move. I read it as two moves at very different speeds.

The proposed swap rule is the political document. It is where the CFTC plants its flag, establishes its theory of jurisdiction, and invites the argument it knows is coming from Ohio, Tennessee, and New Jersey's attorney general. Chairman Michael Selig wants that fight on his terms, in his forum, under his statute. That is a reasonable institutional play, but it is a slow one.

The interim final rule is operational. If it clears OIRA and takes effect, it draws a line between prediction market contracts and casino products at the federal level before any court has formally settled the question. States that have sued prediction market operators on gambling grounds would find their strongest analogy — that event contracts are functionally casino products — specifically excluded from the federal definition that governs. Their argument does not disappear, but its legal surface area shrinks.

I have watched agencies use the two-speed rulemaking structure before, in different sectors, and the tell is always the same: the proposed rule generates the headlines, and the interim final rule generates the facts on the ground. By the time litigation catches up to the interim rule, the regulated entities have already reorganized around it. Reversal is possible but expensive.

What the CFTC cannot control is the Supreme Court's timeline. New Jersey has asked the Court to take the jurisdictional question directly, and the circuit split — conflicting appeals court decisions on whether event contracts qualify as swaps — gives the Court a clean reason to accept. If the Court moves before the interim final rule beds in, the regulatory fait accompli the CFTC is attempting becomes considerably less accomplished.
