U.S. Army soldier Gannon Ken Van Dyke, who earned $400,000 using insider information on the crypto event-betting platform Polymarket, is contesting attempts by the Commodity Futures Trading Commission (CFTC) to intervene in his criminal case. The regulator wants to present its position on the case, which it itself initiated in civil court but never brought to trial.
On August 24, Van Dyke's attorneys filed a motion in the U.S. District Court for the Southern District of New York, objecting to the CFTC's attempt to submit an opinion on a number of key defense arguments. The Commission, in particular, intends to challenge one of the defense's main theses: contracts for events traded on platforms like Polymarket are not swaps and therefore do not fall under the CFTC's jurisdiction.
Van Dyke's lawyers did not mince words in characterizing the regulator's actions. In their view, the CFTC is trying to advance its own interests without engaging in open confrontation over its own lawsuit. The Commission initiated a separate civil case against Van Dyke, which it itself refuses to bring to adjudication. Instead, the regulator is attempting to influence the outcome of the criminal process through the status of an amicus curiae. The defense considers this approach a procedural maneuver that the court should not support.
The attorneys directly stated that the CFTC is a "true predator," pursuing Van Dyke through a backdoor route instead of an open legal dispute.
Essence of the Charges
U.S. authorities charged Van Dyke with fraud in April. According to the prosecution, the serviceman used non-public information to which he had access in the course of his duties to trade event contracts related to the potential removal from power of Venezuelan President Nicolás Maduro in January. This is precisely the episode that lawmakers and critics of prediction markets regularly cite as an example of potential manipulation on platforms like Kalshi and Polymarket.
A federal judge previously stayed the CFTC's civil case against the soldier—until the criminal proceedings are completed. Van Dyke himself has pleaded not guilty to all charges. The criminal trial is expected to begin in late 2026 or early 2027.
The court has not yet ruled on whether the CFTC will be allowed to participate in the criminal case as an amicus curiae. The outcome of this procedural dispute could affect not only Van Dyke's case but also how regulators will interpret the status of event contracts under U.S. law going forward.
AI Perspective
An analysis of CFTC case law reveals an interesting inconsistency in the regulator's approach to insider trading cases on prediction markets. In the case of a Google employee accused of a similar scheme on Polymarket, the commission acted differently: a parallel civil lawsuit was filed on the same day as the criminal charges from the Department of Justice. The situation with Van Dyke is unfolding along a different path—the civil case is frozen, and the commission is seeking a workaround through amicus curiae status.
This discrepancy raises the question of the regulator's legal strategy concerning different defendants. The legal precedent that may arise from the dispute over the status of event contracts could affect not only Polymarket but the entire industry, including Kalshi—a platform whose activities the CFTC has supported in other proceedings. Whether to expect a unified standard of regulatory response to such incidents, or for each case to be decided on its own logic, is a question whose answer will shape the rules of the game for the entire prediction market.
