A U.S. Army Green Beret who helped plan the military operation to capture Venezuelan dictator Nicolás Maduro now faces up to 60 years in federal prison, not for anything that went wrong on the mission, but for allegedly using what he learned in classified briefings to place bets on a prediction market and pocket roughly $410,000.
The Justice Department announced Thursday that Master Sgt. Gannon Ken Van Dyke, 38, stationed at Fort Bragg, North Carolina, was arrested and charged with three counts of violating the Commodity Exchange Act, one count of wire fraud, and one count of unlawful monetary transaction. The Commodity Futures Trading Commission filed a parallel insider-trading complaint, what Newsmax reported appears to be the first time the Justice Department has brought insider-trading charges tied to a prediction market platform.
The charges paint a picture of a soldier who allegedly betrayed his security clearance for a fast payday on Polymarket, the online prediction exchange that lets users wager real money on real-world events. Van Dyke wagered more than $33,000 across 13 bets placed between December 27, 2025, and the evening of January 2, just hours before the operation to seize Maduro commenced. The bets tracked Venezuela-related markets, including whether U.S. forces would enter the country and whether Maduro would be removed from power.
The move won him more than $400,000, authorities said. Nearly $410,000, to be precise.
Van Dyke was involved in the planning and execution of "Operation Absolute Resolve" from around December 8, 2025, through January 6, Fox News Digital reported. Federal prosecutors allege Maduro leads a drug cartel, and the operation targeted him accordingly.
Around December 14, while the mission was still in its planning phase, Van Dyke allegedly created an email address not in his name. That address would later appear on his cryptocurrency exchange account. By December 26, he had allegedly created a Polymarket account, funded it, and begun trading on Venezuela-related markets.
Over the next week, he placed 13 bets. The last came on the evening of January 2. The operation launched just hours later.
On the day of the operation itself, Van Dyke allegedly withdrew the majority of his winnings. Federal prosecutors said he sent most of the proceeds to a foreign cryptocurrency vault before depositing them into a newly created online brokerage account. He then allegedly asked Polymarket to delete his account and changed the email on his cryptocurrency exchange, steps prosecutors describe as an effort to conceal his identity and his trades. The Washington Times reported that he also used a VPN to mask his activity.
By January 5, Maduro and his wife, Cilia Flores, were in handcuffs after landing on a New York City helipad. Federal agents escorted them to a federal courthouse in Manhattan.
The government's response was swift and pointed. Acting Attorney General Todd Blanche framed the case as a warning to anyone with a security clearance and a brokerage account:
"Our men and women in uniform are trusted with classified information in order to accomplish their mission as safely and effectively as possible and are prohibited from using this highly sensitive information for personal financial gain."
Blanche added a line aimed squarely at the growing prediction-market industry. "Widespread access to prediction markets is a relatively new phenomenon, but federal laws protecting national security information fully apply," he said.
FBI Director Kash Patel was equally direct. "Today's announcement makes clear no one is above the law, and this FBI will do whatever it takes to defend the homeland and safeguard our nation's secrets," Patel said. He added: "Any clearance holders thinking of cashing in their access and knowledge for personal gain will be held accountable."
The case raises broader questions about standards of character and accountability within the Army, particularly when soldiers entrusted with the nation's most sensitive operations allegedly exploit that trust for personal enrichment.
CFTC Chairman Michael Selig did not mince words either:
"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."
Selig also said he had been "crystal clear that anyone who engages in fraud, manipulation or insider trading in any of our markets will face the full force of the law."
Polymarket moved quickly to frame itself as part of the solution. The company posted on X on Thursday that it had identified a user trading on classified government information and referred the matter to the DOJ. "Insider trading has no place on Polymarket. Today's arrest is proof the system works," the company wrote.
Polymarket CEO Shayne Coplan posted separately, as the Washington Examiner reported: "We flagged this, referred it, and cooperated throughout the process."
The platform also said it published enhanced rules in March to combat insider trading. But the timeline raises an uncomfortable question: Van Dyke allegedly placed his bets in late December and early January. The enhanced rules came months later.
Meanwhile, rival prediction platform Kalshi told a different story. A source said Van Dyke was blocked from opening an account on Kalshi because of that platform's safeguards, including ID verification requirements. In other words, Van Dyke allegedly tried Kalshi first, got stopped, and found an easier path through Polymarket's offshore structure.
Ben Schiffrin, head of securities policy at Better Markets, highlighted the gap. "The allegations further show how individuals can circumvent the restrictions prediction market platforms supposedly have in place to prevent misconduct," Schiffrin said.
Polymarket's chief legal officer, Neal Kumar, pushed back on X: "It's not anonymous, you will be found just like this guy."
The case sits at the intersection of national security, emerging financial technology, and basic integrity, a combination that demands serious scrutiny of both the individual and the platforms involved. It is not unlike other recent cases involving alleged offenses tied to U.S. military operations and installations, where trust and access become the very tools of betrayal.
U.S. Attorney Jay Clayton, of the Southern District of New York, laid out the government's theory in plain terms. The New York Post reported Clayton's statement:
"The defendant allegedly violated the trust placed in him by the United States Government by using classified information about a sensitive military operation to place bets on the timing and outcome of that very operation, all to turn a profit. That is clear insider trading and is illegal under federal law."
Van Dyke had signed nondisclosure agreements pledging to "never divulge, publish, or reveal by writing, words, conduct, or otherwise... any classified or sensitive information." Prosecutors say he did exactly what he swore he would not.
The War Department referred all questions to federal prosecutors. Breitbart reported the same core set of charges and noted Van Dyke faces up to 50 years if convicted on all counts, though the Fox News Digital account and other outlets put the maximum at 60 years.
The discrepancy in potential sentencing figures remains unresolved, but either number represents a staggering price for what prosecutors describe as a calculated scheme to cash in on a classified military operation.
Prediction markets have exploded in popularity. Polymarket gained mainstream attention during the 2024 election cycle, and platforms like Kalshi have pushed for regulatory approval to offer contracts on everything from economic data to geopolitical events. The Van Dyke case is a stress test for the entire industry.
The question is not whether insider trading laws apply to prediction markets. Blanche answered that plainly: they do. The question is whether platforms can police themselves well enough to catch the next person with a security clearance and a crypto wallet before the damage is done.
Kalshi's safeguards apparently caught Van Dyke. Polymarket's did not, at least not before he placed 13 bets and walked away with six figures. The platform says it eventually flagged the activity and cooperated. But "eventually" is doing a lot of work in that sentence.
The military has faced its share of accountability questions involving service members in recent months. This case is different in kind. A Green Beret with access to one of the most sensitive operations in recent memory allegedly used that access not to protect his country, but to enrich himself on a betting platform.
Several open questions remain. What specific classified information did Van Dyke allegedly use to inform his bets? Did anyone else with access to Operation Absolute Resolve place similar wagers? And how many other clearance holders across the government are watching prediction markets right now, weighing the odds?
The Justice Department, the FBI, and the CFTC have now drawn a bright line. Whether that line holds depends on whether platforms tighten their controls, and whether the next soldier tempted to trade on secrets remembers that a uniform comes with obligations that don't expire when you log into a crypto exchange.
A man trusted with his nation's most closely held plans allegedly sold that trust for a Polymarket payout. If the charges hold, the system worked, but only after the bet was placed, the money was moved, and the damage was done.
