The Department of Justice charged Army Sergeant Van Dyke with using classified information to place bets on the prediction market platform Polymarket, marking what prosecutors say is a first-of-its-kind case. The indictment, filed in federal court, accuses Van Dyke of misappropriating sensitive government data to gain an edge in wagers on political and financial outcomes. Legal observers say the case establishes a precedent: misusing non-public data from the government or a corporation now carries the same legal consequences as Wall Street securities fraud.
The charges against Van Dyke
Van Dyke, a non-commissioned officer stationed at Fort Bragg, faces counts of wire fraud and unauthorized disclosure of classified information. According to the DOJ, he accessed intelligence reports and operational details that were not available to the public, then used that data to place winning bets on Polymarket — a platform where users trade on the outcome of real-world events. Prosecutors allege the scheme ran for more than a year, with Van Dyke depositing winnings into personal accounts.
The government says the case is not just about one soldier's side hustle. It's about data integrity. The DOJ's criminal division called the conduct a breach of trust that undermines national security and market fairness. Investigators identified the pattern after an internal military audit flagged unusual trading activity linked to Van Dyke's personal devices.
How the scheme worked
Van Dyke held a security clearance that gave him access to daily intelligence briefings, troop movements, and policy deliberations. Prosecutors say he used that knowledge to predict outcomes on Polymarket markets tied to military deployments, diplomatic negotiations, and even election results. He didn't share the classified material with anyone else — he used it directly to decide which bets to place.
The indictment lists dozens of specific wagers, including bets on whether a foreign leader would resign within a set timeframe and whether a certain weapons system would pass a test. In each case, the classified data gave him information the public didn't have. The DOJ says his win rate on those bets was more than double the platform average.
Polymarket is not a regulated exchange, but the DOJ argues that federal law covers any scheme to defraud using inside information, regardless of the platform. The theory extends the logic of insider-trading law beyond traditional securities to any market where information has value.
Legal experts not involved in the case say the indictment could reshape how prosecutors treat data theft in the gig economy and on alternative trading platforms. Past cases focused on corporate trade secrets or government leaks to the press. This one targets a person who used classified data for personal profit on a platform that has no formal insider-trading rules.
The DOJ explicitly drew the parallel to securities fraud in its press release. The message: if you steal information — whether from the Pentagon or a private company — and trade on it, you are committing wire fraud. The case sidesteps the question of whether Polymarket itself did anything wrong. The agency is focused on the source of the data, not the venue where it was used.
For companies that rely on non-disclosure agreements and data access logs, the ruling provides a clear signal. An employee who passes a confidential sales figure to a friend betting on a prediction market could face the same charges as a Wall Street analyst leaking earnings reports.
What happens next
Van Dyke is currently in military custody pending a detention hearing scheduled for next week. His civilian attorney has not yet filed a response to the charges. The case will be tried in federal district court in North Carolina, where a judge will have to decide whether the securities-fraud analogy holds in a market that deals in political predictions rather than stocks or bonds.
One unresolved question: will the DOJ pursue similar charges against other users who accessed classified or corporate data to bet on prediction platforms? The agency has not said whether it is investigating additional cases, but the precedent now exists.
