A federal judge has paused the Commodity Futures Trading Commission's civil case against Gannon Ken Van Dyke, a US Army Special Forces master sergeant accused of using nonpublic information to profit more than $400,000 on Polymarket contracts tied to the ouster of Venezuelan President Nicolás Maduro. District Judge Andrew Carter, sitting in the Southern District of New York, granted a motion filed by federal prosecutors in July to stay the CFTC's civil action pending the outcome of the parallel criminal proceeding.
Van Dyke has pleaded not guilty to all charges and has moved to dismiss the criminal indictment outright, arguing the CFTC's treatment of Polymarket's event contracts as regulated "swaps" is legally ambiguous. Prosecutors allege Van Dyke was involved in the operation to remove Maduro and used that access to place large, well-timed bets shortly before US forces captured the Venezuelan leader on January 3.
Part of a wider enforcement push
The case is one prong of a much broader regulatory reckoning for prediction markets. In the same window as the Maduro contracts, Polymarket's offshore exchange also saw a sharp spike in large purchases of contracts predicting US military strikes on Iran, shortly before those strikes actually occurred in February — a pattern regulators have flagged as evidence that platforms need tighter controls around who can trade on outcomes they may have advance knowledge of. Lawmakers have moved in parallel: Rep. Ritchie Torres introduced the Public Integrity in Financial Prediction Markets Act of 2026 in January, a bill with more than 40 Democratic co-sponsors that would bar anyone holding material nonpublic information about a government-related event from trading on prediction markets tied to it.
Platforms are already tightening the rules
Polymarket and rival Kalshi didn't wait for legislation to catch up. In March, both platforms rolled out new insider-trading safeguards explicitly barring traders from acting on stolen confidential information, profiting from illegal tips, or wagering on any contract where they hold enough authority to influence the outcome themselves. Kalshi went further, deploying screening tools — including a partnership with an integrity-monitoring vendor — to block officials, athletes, and other insiders from betting on events they're directly involved in.

What the stay means going forward
For Van Dyke, the stay effectively pauses financial penalties and discovery obligations in the civil case until the criminal trial — which could begin in late 2026 or early 2027 — plays out first, a standard sequencing move that prevents statements made in a civil deposition from complicating his criminal defense. For the industry, the case is likely to become a key test of how far the CFTC's "swaps" framework can stretch to cover event contracts, a question regulators are also probing more broadly as scrutiny of politically sensitive information flows into crypto-adjacent markets continues to intensify heading into next year.
