Van Dyke defense wins first round as CFTC blocked from criminal case

A federal judge in the Southern District of New York has already told the CFTC it cannot pursue its civil case against Gannon Ken Van Dyke while the criminal proceeding runs. Now Van Dyke's lawyers are making a second, sharper argument: the regulator cannot slip its positions into the criminal case through an amicus brief either.

The CFTC had filed a notice requesting permission to offer its views on Van Dyke's defense claims, particularly the claim that event contracts on platforms like Polymarket do not constitute "swaps" under the Commodity Exchange Act and therefore fall outside CFTC jurisdiction entirely. The defense filing on Monday called that move what it appears to be — a regulatory agency trying to shape a criminal prosecution it is formally barred from joining. The "regulatory wolf" language from defense counsel was theatrical, but the structural argument underneath it is not.

Here is what makes this sequence worth watching carefully. The CFTC's civil case is stayed. The agency chose not to push to lift that stay. Instead it sought amicus status in the criminal proceeding, which would let it argue the jurisdictional question — what prediction market contracts actually are — without having to face Van Dyke's lawyers in direct litigation. The defense is correct that this is not a neutral friend-of-the-court posture. It is a jurisdiction argument the CFTC needs to win, filed through a door it normally would not use.

The underlying charge is fraud, not a CFTC violation. US authorities say Van Dyke used nonpublic information about a Venezuela operation to trade event contracts on Polymarket's Maduro removal market, generating more than $400,000. He has pleaded not guilty. A criminal trial is unlikely before late 2026 at the earliest.

But the jurisdictional question the defense is pressing — whether these contracts are swaps — is not merely a defense tactic. It is the same question Nevada, Illinois, and several other states are pressing from the other direction: what exactly is the regulatory category that prediction market contracts occupy, and who has the authority to say so. The CFTC's interest in answering that question through any available proceeding is genuine, and the Van Dyke case is currently the highest-profile venue where the answer might be forced.

In a previous position working on exactly this kind of regulatory ambiguity, the pattern was consistent: agencies file amicus briefs when they want a legal record without the exposure of primary litigation. The CFTC's move here is not unusual in form. What is unusual is how transparent the strategic interest is, and how directly the defense named it.
