The 38-year-old reportedly turned approximately $33,000 in wagers into more than $400,000 in profit.

Why This Matters
This case represents a landmark prosecution involving insider trading on a decentralized prediction market using national security secrets. It signals that US law enforcement treats prediction platforms as legitimate financial venues subject to existing fraud and insider trading laws. For the broader prediction market industry, this is a clear warning that regulatory scrutiny is intensifying.
From Classified Operations to Crypto Wallets
According to prosecutors, Van Dyke participated in the planning and execution of "Operation Absolute Resolve," a mission targeting former Venezuelan President Nicolás Maduro. His role gave him access to classified details about the timing and specifics of the operation.
Armed with this non-public intelligence, Van Dyke allegedly placed around $33,000 worth of bets on related events on Polymarket and reaped over $400,000 in returns. After cashing out, prosecutors claim he attempted to cover his tracks using an offshore cryptocurrency wallet and a brokerage account.
Van Dyke faces five charges:
- Unauthorized use of confidential government information
- Theft of non-public data
- Commodities market fraud
- Wire fraud
- Illegal financial transactions
Four of the five charges carry a maximum sentence of 10 years in prison. The wire fraud count alone could result in up to 20 years behind bars.
Officials and Polymarket Respond
Acting US Attorney General Todd Blanche stated that access to classified information cannot be leveraged for personal enrichment. Jay Clayton, the US Attorney for the Southern District of New York, described the alleged conduct as "obvious insider trading" and pledged that his office will continue prosecuting those who exploit confidential or classified information in ways that undermine national security.
Polymarket itself disclosed that it identified the suspicious trading activity internally and proactively referred the case to the DOJ, cooperating fully with the subsequent investigation.
«Last month, we published our enhanced market integrity rules to combat insider trading. When we identified a user trading on classified government information, we referred the matter to the DOJ & cooperated with their investigation. Insider trading has no place on Polymarket.» — Polymarket (@Polymarket), original post
The platform noted it had recently strengthened its internal rules specifically targeting insider activity.
A Pattern of Prediction Market Manipulation Concerns
The Van Dyke case is not the first manipulation scare on Polymarket. Earlier in April, two accounts drew suspicion after earning $37,000 by correctly predicting anomalous temperature readings at a weather station at Paris's Charles de Gaulle airport. However, the scale and national security implications of the Van Dyke prosecution far exceed previous incidents and could set a new precedent for enforcement across the prediction market sector.
