The United States Department of Justice has filed criminal charges against an active-duty soldier for placing a bet on the abduction of Venezuelan President Nicolas Maduro, using classified military information for personal profit.

On Thursday, prosecutors accused Gannon Ken Van Dyke, 38, of cashing in on the operation against Maduro, to the tune of more than $400,000.

They say he used the prediction market platform Polymarket 13 times to bet on topics including whether US forces would “invade” Venezuela and when Maduro would be removed from office. Officials framed his actions as a dire breach of public trust.

“Gannon Ken Van Dyke allegedly betrayed his fellow soldiers by utilizing classified information for his own financial gain,” said James C Barnacle Jr, an assistant director at the Federal Bureau of Investigation (FBI).

Van Dyke has been charged with three counts of violating the Commodity Exchange Act, one count of wire fraud and one count of carrying out an unlawful monetary transaction.

Each commodities fraud and unlawful transaction charge carries a maximum sentence of 10 years in prison. The wire fraud charge could result in up to 20 years.

The availability of prediction markets — online betting platforms where users can gamble on real-world events — has expanded under the second presidency of Republican leader Donald Trump.

Administration officials and close advisers to Trump, including his son Donald Trump Jr, maintain ties to the prediction market industry.

Trump Jr, for example, was named a “strategic adviser” to the prediction market Kalshi in January 2025, shortly before his father was sworn in.

In May 2025, less than five months into Trump’s second term, the Commodity Futures Trading Commission dropped its legal fight against Kalshi, paving the way for bets to be placed on political events like elections.

Since then, prediction markets have proliferated in the US, with some bets raising questions about the prospect of insider trading.

Critics fear government officials and other politicians could use the platforms to bet on actions they themselves control.

The sizeable bets made ahead of the US attack on Venezuela on January 3, 2026, were among the instances that raised red flags, with media outlets reporting on the “mystery trader” who scored big.

Thursday’s unsealed indictment (PDF) makes the Justice Department’s case for why Van Dyke was the trader in question.

According to the criminal complaint, the soldier — who was based at Fort Bragg in Fayetteville, North Carolina — created a Polymarket account around December 26, 2025, using a virtual private network (VPN) to place his location abroad.

Within days, he was making bets related to Venezuela that prosecutors say leveraged the classified intelligence he was privy to.

Around December 27, he bought $96 worth of bets on the prospect that US forces would be in Venezuela by January 31. A few days later, on December 30, he placed roughly $1,323 in bets on Maduro being out of office before the end of January.

His gambling continued as the military operation ticked closer. On January 1, he gambled $6,100 on a range of different scenarios, including Maduro being ousted, the US invading Venezuela, and Trump invoking war powers against Venezuela.

The following day, he placed even more bets, worth $6,150, $6,000, $7,050 and $7,215 a piece.

Then, in the early hours of January 3, the US launched its military operation against Venezuela, culminating in the abduction and imprisonment of Maduro and his wife, Cilia Flores.

Dozens of Venezuelans and Cubans died in the attack, which was confirmed to the public at 4:21am US Eastern Time (08:21 GMT).

The indictment explains that Van Dyke “was involved in the planning and execution of Operation Absolute Resolve”, as the military attack was called.

“He possessed material nonpublic information about that operation at the time of each and every trade he placed in Maduro and Venezuela-related markets,” the indictment alleges.

Shortly after his $400,000 windfall, prosecutors say Van Dyke transferred much of his proceeds to a foreign cryptocurrency vault. By January 6, he contacted Polymarket to delete his account.

Thursday’s indictment comes one day after Kalshi revealed it had fined and suspended three users who were allegedly candidates in the 2026 midterm elections. All three had placed bets on the outcomes of their own races.
