Pentagon Bans Military Personnel from Betting on Prediction Markets
By Drooid · · How we work
Core Directive
Defense Secretary Pete Hegseth issued a one-page memorandum on October 20, 2026 prohibiting all Department of Defense (DoD) personnel—from active-duty service members to civilian employees—from using classified or non-public information to place wagers on military outcomes in online prediction-market platforms such as Polymarket and Kalshi. The memo states that violations may result in administrative punishment and criminal prosecution under the Uniform Code of Military Justice (UCMJ) and applicable federal law.
Background & Context
The directive follows a series of high-profile incidents in which service members allegedly leveraged insider knowledge for financial gain. In April 2026, Master Sgt. Gannon Ken Van Dyke was indicted for using classified details of a Special Forces operation aimed at Venezuelan President Nicolás Maduro to place bets on Polymarket. Federal prosecutors allege that Van Dyke’s wagers, made in the days surrounding the operation, generated profits exceeding $400,000. Earlier, the same platform was linked to accounts that placed precise bets on a prospective U.S.–Iran ceasefire shortly before the announcement, yielding “hundreds of thousands of dollars” in profits for those users.
Data & Statistics
- $400,000+ – alleged profit earned by Van Dyke from bets tied to the Maduro operation (source: multiple outlets).
- $32,500 – amount cited in some reports as the total Van Dyke wagered on the Maduro timeline.
- Hundreds of thousands of dollars – profits reported for new Polymarket accounts that bet on a U.S.–Iran ceasefire before it was publicly announced.
- Three congressional candidates – suspended by Kalshi for betting on their own election outcomes (mentioned as a related enforcement action).
Official Statements & Responses
The memorandum emphasizes that “our enemies watch movements in these markets,” warning that financial signals can provide hostile intelligence services with actionable foresight. The DoD indicated that the policy is effective immediately and that no additional details on oversight mechanisms will be disclosed. A Pentagon spokesperson declined to comment beyond confirming the memo’s issuance.
On-the-Ground Reports
Investigations revealed that Van Dyke placed his bets moments before the first missiles were launched toward Caracas, exploiting his direct access to operational plans. The case illustrates how insider trading on prediction markets could create conflicts of interest, potentially influencing logistical or analytical decisions within the military chain of command.
Conflicting Reports & Gaps
Sources differ on the scale of Van Dyke’s financial activity:
- Some reports cite more than $400,000 in winnings.
- Others specify that the total amount wagered was $32,500.
The discrepancy has not been resolved in publicly available filings, and the Department has not released a definitive figure.

What’s Next
The directive is binding across the entire DoD and applies to any future use of non-public information for market speculation. Personnel are now required to cease all such activity, and the Pentagon has signaled that violations will be pursued aggressively under existing military and federal statutes.
