Van Dyke defense reframes Polymarket contracts as outside CFTC reach

Gannon Ken Van Dyke's lawyers did not simply oppose the CFTC's amicus request on Monday. They redefined the terrain the entire case will be decided on.

The filing in the Southern District of New York argued that event contracts on platforms like Polymarket are not "swaps" within the CFTC's statutory jurisdiction. That is the defense's core position — and it is the one the CFTC most needs to answer before any court, because if Van Dyke's lawyers are right, the Commission has no civil case, no standing as a friend of the court in the criminal matter, and no regulatory hook into the platform where the $400,000 trade occurred.

The CFTC's civil case against Van Dyke was already stayed pending the criminal outcome. So the Commission filed a notice seeking to submit an amicus brief in the criminal proceeding — to get its jurisdictional arguments in front of a judge through a door it could not open directly. Van Dyke's lawyers called it precisely what it is: regulatory self-interest dressed as neutral guidance. "A regulatory wolf," their filing says, not a sheep.

That framing is aggressive, but it is also legally coherent. An amicus brief is supposed to assist the court. When the entity filing it has pending claims against the defendant — claims it chose not to pursue — the assistance and the interest are the same thing. The court can read that. The filing makes sure it does.

The jurisdictional question is the one that matters here, not the facts of the underlying trade. Van Dyke allegedly used nonpublic information about a Venezuelan government operation to position on Polymarket's Maduro removal contract. The fraud charges do not depend on whether Polymarket contracts are swaps. But the CFTC's civil exposure — and the industry's regulatory architecture — depends on almost nothing else.

I have watched regulators use the amicus mechanism to rehearse arguments they cannot yet make in their own proceedings. The move is not unusual. What is unusual is a defense team naming it openly and asking the court to reject it on that basis. That gambit works only if the judge already has doubts about the Commission's posture — and a stayed civil case gives the court reason to look at the CFTC's litigation strategy with some skepticism.

The swap classification question has not been resolved by any court with direct jurisdiction over retail event contracts on platforms operating under CFTC self-certification. If Van Dyke's lawyers succeed in keeping the CFTC's amicus brief out, the criminal court issues its own jurisdictional rulings without the Commission's framing in the record. That outcome would leave the definitional question open in exactly the way the industry's opponents least want — decided piecemeal, in criminal rather than civil proceedings, where the CFTC has the least control over the result.
