Judge keeps soldier's Polymarket insider trading case alive
A federal judge on Wednesday refused to dismiss an insider trading case against Gannon Ken Van Dyke, a U.S. Army Special Forces master sergeant. Van Dyke is accused of using classified government contract information to place profitable bets on Polymarket before the information became public. Polymarket is not a party to the criminal case. The ruling preserves one of the first prosecutions testing whether traditional insider trading law applies to prediction market wagers.
The ruling advances the first felony test of whether securities insider-trading doctrine reaches prediction-market bets. Van Dyke faces decades in prison if convicted, establishing that classified leaks to Polymarket carry criminal weight beyond ethics discipline. That precedent directly sharpens the Pentagon's recent ban on troops trading nonpublic military information, which named Polymarket and Kalshi as venues of concern.
For platforms, the case creates a new regulatory vector: federal prosecutors building securities-fraud precedent without waiting for the CFTC or state courts. Institutional liquidity providers already jittery about Pentagon attention now face the added risk of DOJ conspiracy theories if their markets attract classified leaks. The next platform to list defense or geopolitical contracts must price in both the Pentagon ban and potential wire-fraud exposure for any participant with security clearance.
