A US military member is expected to face criminal charges after winning more than $1 million betting on Polymarket ahead of looming American actions against Iran and Venezuela.
The staggering windfall was first reported by the Wall Street Journal and confirmed by a source familiar with the investigation. The identity of the newly minted millionaire remains unclear, as do the particular operations on which the service member gambled. The case represents one of the most brazen alleged uses of inside military information for personal financial gain in recent memory.
The Justice Department has already moved aggressively against similar schemes this year. In April, prosecutors charged an Army special forces member with earning $400,000 betting on the US capture of Venezuelan President Nicolás Maduro. In that case, authorities are alleging unlawful use of confidential government information for personal gain, wire fraud and money laundering.
The Polymarket platform allows users to wager cryptocurrency on the outcomes of real-world events, from elections to geopolitical conflicts. The Iran and Venezuela markets drew massive attention as tensions escalated, with hundreds of millions of dollars in total volume flowing through related contracts.
The suspected military member’s bets were placed with remarkable timing ahead of American military actions, according to the source familiar with the probe. The precise window of the wagers and the exact contracts purchased have not been publicly disclosed.
In the viral moment that helped spark broader scrutiny of prediction market insider trading, President Trump’s longtime teleprompter operator was placed on leave in July after being caught winning $100,000 with bets on Kalshi about the content of speeches ahead of their delivery. That operator, who had worked for Trump since 2017, had access to presidential remarks before they were delivered publicly.
The convergence of military operations and prediction markets has created a new frontier for federal prosecutors already stretched by cryptocurrency-related enforcement. The Commodity Futures Trading Commission has also taken increasing interest in platforms like Polymarket and Kalshi as they have grown in popularity and market size.
Democratic lawmakers have begun eyeing new prediction market laws after the massive Iran war bets paid off, with some senators alleging insider trading over a $1.5 billion trade placed before Trump announced a halt to Iran strikes. Six Polymarket traders netted roughly $1 million on US-Iran strike contracts, sparking fears across the industry that privileged information was fueling outsized returns.
The Army special forces member charged in April allegedly used classified information about US operations against Maduro to place his winning wagers. That case remains pending and has become a template for how prosecutors may approach the newest military betting investigation.
The current investigation into the $1 million Polymarket winner is expected to produce charges in the coming weeks, according to the source familiar with the matter. Federal agents have reportedly traced wallet addresses and transaction patterns to identify the service member behind the bets.
