The phrase that landed in the Southern District of New York on Monday was not lawyerly. Van Dyke's defense attorneys called the CFTC a "regulatory wolf" — not a friend of the court but a predator trying to advance its own interests through borrowed standing. The image was theatrical. The legal argument underneath it was not.
Gannon Ken Van Dyke, a soldier charged with fraud for allegedly trading event contracts on Polymarket using nonpublic information about the removal of Venezuelan President Nicolás Maduro, has pleaded not guilty. A federal judge has already stayed the CFTC's parallel civil case against him until the criminal proceeding concludes. The Commission is not currently in that courtroom. What it wants is to be in the criminal one, as an amicus — a friend offering views on whether event contracts on platforms like Polymarket constitute "swaps" subject to CFTC authority under the Commodity Exchange Act.
Van Dyke's lawyers are opposing that entry. Their argument is not subtle: the CFTC has its own case, chose not to pursue it while the criminal matter is live, and should not be permitted to shape the legal record in the criminal proceeding as a substitute for facing the defendant directly.
This is where the jurisdictional architecture becomes the real story. Whether event contracts on Polymarket are "swaps" under the CEA is not a fact question — it is a classification question that the criminal court will have to resolve, and the CFTC's view of that classification, if entered into the record, shapes the analytical framework the judge applies. The defense understands that. The Commission understands that. The amicus vehicle, in this reading, is not neutral commentary. It is a filing with consequences.
I have watched regulators use the amicus brief as a positioning tool in enforcement-adjacent proceedings before — not to win the immediate case but to establish language that survives into future actions. A Commission statement that Polymarket contracts are swaps, accepted into the criminal record without the adversarial pressure of a full evidentiary hearing, would carry weight in every state and federal proceeding that follows.
Van Dyke's guilt or innocence is for the jury. The swap classification is a different matter entirely, and it will not be resolved cleanly here regardless of how the criminal trial ends. The resolution condition for any prediction market tracking the CFTC's jurisdictional reach over event contracts is not the Van Dyke verdict — it is whether a court at the circuit level, with full briefing from both sides, eventually writes a holding on what these instruments are.
Under 7 U.S.C. § 1a(47), a "swap" includes any agreement that provides for payment dependent on the occurrence of an event — but the statute carves out contracts that are not entered into for investment purposes and that are excluded by CFTC rule. The self-certification process Kalshi used, and the designated contract market framework, are supposed to be the mechanism for resolving exactly this ambiguity before a criminal defendant ends up in federal court arguing definitional questions under oath. That the question remains live in a criminal proceeding in 2026 is the institutional failure the defense brief, despite its wolf metaphor, is actually pointing at.

Under 7 U.S.C. § 1a(47), a swap includes any agreement providing payment dependent on an event's occurrence, but the statute carves out contracts not entered for investment purposes and those excluded by CFTC rule. Event contracts on platforms like Polymarket may qualify for exemption depending on their purpose and regulatory status. The classification determines whether the CFTC has jurisdiction over these instruments.
Van Dyke's defense attorneys argued the CFTC is using the amicus vehicle as a back-door prosecution, not neutral commentary. The CFTC stayed its own parallel civil case but seeks to enter the criminal proceeding to establish that Polymarket contracts are swaps subject to CFTC authority under the Commodity Exchange Act. The defense contends this allows the Commission to shape legal precedent without facing the defendant directly in an adversarial hearing.
Van Dyke's acquittal would not resolve the jurisdictional question of whether Polymarket contracts constitute swaps under the Commodity Exchange Act. The swap classification is separate from the fraud verdict and will require resolution at the circuit court level through full briefing from both parties. Any statement by the criminal court accepting the CFTC's swap classification could influence how state and federal regulators treat these instruments in future enforcement actions.
The resolution condition for prediction markets tracking CFTC jurisdictional reach over event contracts is not the Van Dyke verdict itself, but whether a federal appellate court eventually issues a binding holding on the swap classification for these instruments. A circuit-level ruling with full adversarial briefing would establish precedent that shapes how Polymarket and similar platforms face regulatory treatment across multiple jurisdictions.
