DOJ and CFTC charge Van Dyke in first prediction-market insider trading case
Federal prosecutors in the Southern District of New York and the Commodity Futures Trading Commission have brought parallel charges against a defendant named Van Dyke in the first insider trading case tied to prediction markets, according to a Sidley.com summary dated May 13. The indictment and CFTC complaint signal that authorities intend to rely on the traditional misappropriation theory of fraud to test how existing securities and commodities fraud frameworks apply to event contract markets. The case comes as the DOJ and CFTC accelerate enforcement against insider trading on prediction markets they oversee, with the US House Oversight Committee also launching an investigation into insider trading on these platforms following a February CFTC advisory asserting regulatory authority over the practice.
Van Dyke's prosecution tests whether misappropriation theory transfers cleanly to event contracts; any conviction gives CFTC enforcement a template to deploy against Kalshi and Polymarket surveillance gaps. Platforms must now build insider-trading compliance programs or risk co-defendant exposure in future DOJ-CFTC parallel actions.
Van Dyke now joins Spagnuolo as the second federal insider-trading prosecution tied to prediction markets in this enforcement streak, with the DOJ-CFTC pairing testing misappropriation theory across multiple platforms while Kalshi and Polymarket simultaneously face congressional document demands and state enforcement in Nevada and Washington.
