RALEIGH, N.C. — A U.S. special forces soldier who took part in the capture of Venezuelan President Nicolás Maduro will be released on bond on charges accusing him of using classified information about the operation to win more than $400,000 in an online prediction market, a federal magistrate said Friday.

The magistrate in North Carolina said he would allow Gannon Ken Van Dyke to be released and told him to report to a New York federal courthouse by Tuesday to continue his case there.

Bearded with arm tattoos, Van Dyke said little during the nearly hourlong hearing, during which he was appointed a federal public defender who declined to comment afterward. The $250,000 unsecured bond did not require Van Dyke to put up any money.

Federal prosecutors say Van Dyke used his access to classified information about the operation to capture Maduro in January to win money on the prediction market site Polymarket.

The sites allow people to trade on almost anything — from the Super Bowl to U.S. elections and even the winners of the TV reality shows.

Van Dyke, who is stationed at Fort Bragg near Fayetteville, N.C., was charged Thursday with the unlawful use of confidential government information for personal gain, theft of nonpublic government information, commodities fraud, wire fraud and making an unlawful monetary transaction.

He could face up to 10 years on four of the criminal counts, and up to 20 years on a fifth, the government said Friday. A publicly listed phone number listed for Van Dyke isn’t in service.

Van Dyke, 38, was involved for about a month in the planning and execution of capturing Maduro, according to the New York federal prosecutor’s office. He signed nondisclosure agreements promising to not divulge “any classified or sensitive information” related to the operations, but prosecutors say he used what he knew to make a series of bets related to Maduro being out of power by Jan. 31.

“This involved a U.S. soldier who allegedly took advantage of his position to profit off of a righteous military operation,” FBI Director Kash Patel said in a social media post.

Polymarket, one of the largest prediction markets, said it found someone trading on classified government information, alerted the Justice Department and “cooperated with their investigation.”

Massive profits from well-timed bets aroused public attention days after the raid in Venezuela and brought bipartisan calls for stricter regulation of the markets.

The sudden rise of these markets has led to growing scrutiny by Congress and state governments. Some lawmakers alarmed by highly specific, well-timed trades on the U.S. and Israel’s war against Iran and wagers on President Trump’s next moves have pushed for guardrails against insider trading.

The Trump administration has been supportive of the industry’s expansion. The president’s eldest son is an advisor for both Polymarket and its main competitor, Kalshi,, and is a Polymarket investor. Trump’s social media platform, Truth Social, is launching its own prediction market called Truth Predict.

The Commodity Futures Trading Commission, the federal agency that regulates prediction markets, announced Thursday that it had filed a parallel complaint against Van Dyke.

That complaint alleges that Van Dyke moved $35,000 from his personal bank account into a cryptocurrency exchange account on Dec. 26 — a little over a week before U.S. forces flew into Caracas and seized Maduro.

Van Dyke made a series of bets on when Maduro might be removed from power, according to the complaint. He placed those bets between Dec. 30 and Jan. 2, with the vast majority occurring the night of Jan. 2 — just hours before the first missiles struck Caracas.

The bets resulted in “more than $404,000 of profits,” the complaint says.

“The defendant was entrusted with confidential information about U.S. operations and yet took action that endangered U.S. national security and put the lives of American service members in harm’s way,” said Michael Selig, the commission’s chairman.

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.

Météo-France has initiated an inquiry to determine whether the meteorological infrastructure managed by them was targeted by individuals seeking to influence prediction markets.

This development follows reports of highly unusual temperature spikes that triggered significant financial payouts on the blockchain-based site Polymarket, where users place wagers on real-world events.

Investigators are examining if the integrity of the national weather network was breached through physical or digital interference, as the precision of the winning bets suggests the actors involved may have had direct control over the reported data.

Online rumors, which remain unverified for the time being, claim the temperature reading was manipulated by someone using a hair dryer to generate a higher temperature.

Polymarket reportedly settles Paris temperature bets on a single Météo-France sensor sitting near the Charles de Gaulle airport perimeter.

On 6 April, the reading from the sensor abruptly rose 4°C in twelve minutes, crossing the 22°C threshold despite data from other sources showing different figures.

A user on Polymarket aggressively bet on readings above 21°C on that specific day, even though the consensus was lower at 18°C, and profited almost €30,000.

A second similar anomaly occurred on 19 April leading to suspicions that the sensor was tampered with.

Météo-France announced that it has filed a complaint with the Roissy air transport gendarmerie brigade “for [the] alteration of the operation of an automated data processing system,” after an analysis of sensor data.

Polymarket suspended its reliance on the compromised weather data source for Paris, shifting its resolution metric from the sensor in Charles de Gaulle airport to the one in Paris-Le Bourget airport.

However, it did not cancel the contracts or refund the bets, leaving the resolved contracts final, even though on previous occasions it has suspended the resolution of certain bets until further clarification on the rules and circumstances.

Decentralised ‘oracles’ and prediction markets

This incident has reignited the debate over the reliability of the “oracles” that feed data to prediction markets in order to settle bets.

In decentralised finance, an oracle is the mechanism that feeds external, real-world information into a smart contract to determine a financial outcome.

Polymarket relies on these feeds to settle its contracts, often pulling data directly from official government websites. If the primary source of that data is corrupted, the betting market lacks any internal mechanism to verify the truth.

Additionally, the decentralised nature of these platforms makes it difficult to freeze assets even if an investigation identifies the individuals behind suspicious trades.

This is the latest case that highlights a new frontier of white-collar crime, where the manipulation of the physical world is used to exploit the vulnerabilities of automated prediction markets in order to win bets on real-world events.
