Deep Tide Introduction: The U.S. Department of Justice arrested Army Special Forces Sergeant Gannon Ken Van Dyke on Thursday, accusing him of using confidential information obtained during the operation to raid Venezuelan President Maduro to place a $33,000 bet on Polymarket predicting Maduro's departure, netting over $409,000. This is the first case of the U.S. Department of Justice prosecuting insider trading in prediction markets and also the first that the Commodity Futures Trading Commission (CFTC) has applied the "Eddie Murphy Rule" to charge abuses of government non-public information.

A U.S. Special Forces soldier involved in capturing Maduro used confidential intelligence to bet in the prediction market, earning $400,000, and now finds himself as a defendant.

According to a notice from the U.S. Department of Justice on April 23, Army Special Forces Sergeant Gannon Ken Van Dyke (38 years old, stationed at Fort Bragg, North Carolina) was arrested and charged by federal authorities for allegedly profiting from trading on the prediction market Polymarket using confidential information. The indictment shows that Van Dyke participated in the planning and execution of "Operation Absolute Resolve," which aimed to capture Venezuelan President Maduro and his wife in Caracas on January 3, 2026.

The indictment states that Van Dyke opened a Polymarket account on December 26, 2025, and placed a total of 13 bets from December 27 to January 2, investing approximately $33,034, all betting on the "yes" direction, covering four contracts: "Maduro will resign before January 31," "U.S. invasion of Venezuela," "U.S. military entering Venezuela," and "Trump invoking war powers against Venezuela."

The final net profit was approximately $409,881. The largest single bet was $32,537 on "Maduro will resign before January 31," with a return rate of 1,242%, resulting in a profit of $404,222.

First Case Established: DOJ and CFTC Strike Simultaneously

This is the first time the U.S. Department of Justice has filed a criminal lawsuit for insider trading in prediction markets, and it is also the first time the Commodity Futures Trading Commission (CFTC) has charged insider trading in event contracts.

The CFTC simultaneously filed a civil lawsuit in the Southern District of New York, seeking the return of profits from Van Dyke, imposing civil penalties, and permanently banning him from participating in futures trading. CFTC Chairman Michael S. Selig stated in a press release that the defendant's actions jeopardized U.S. national security and put soldiers' lives at risk.

Van Dyke faces five federal charges: three counts of violating the Commodity Exchange Act (each carrying a maximum of 10 years in prison), one count of wire fraud (maximum 20 years in prison), and one count of illegal currency trading (maximum 10 years in prison).

The legal basis for this case is particularly noteworthy. According to Axios, the CFTC is invoking the so-called "Eddie Murphy Rule," which originated from Section 746 of the Dodd-Frank Act of 2010, named after the movie "Trading Places," which explicitly prohibits trading commodities using stolen or misused government non-public information.

Destruction of Evidence Unsuccessful, Polymarket Actively Cooperates with Investigation

The indictment also reveals Van Dyke's cover-up actions after profiting from the bets.

On the day of the operation (January 3), Van Dyke promptly withdrew most of his profits from his Polymarket account and transferred them into an overseas cryptocurrency vault, then deposited them into a newly opened online brokerage account. On January 6, when media and social platforms began reporting unusual trading activities related to Maduro on Polymarket, Van Dyke requested Polymarket to delete his account, falsely claiming he had lost access to his registered email. On the same day, he also changed the registered email for his cryptocurrency exchange account to an address not in his name, which had been registered as early as December 14, 2025.

According to the indictment, hours after the operation ended, a photo of Van Dyke was uploaded to his Google account. The photo showed him in military combat gear, holding a rifle, standing with three other soldiers on the deck of a warship, with a sunrise over the ocean in the background.

Polymarket issued a statement on the X platform, stating that after discovering a user had traded using confidential government information, the company proactively referred the matter to the Department of Justice and fully cooperated with the investigation. Polymarket Chief Legal Officer Neal Kumar stated that the platform is not anonymous, and users can be located like this individual.

Risks of Insider Trading in Prediction Markets Extend Beyond the Maduro Case

The Van Dyke case is not an isolated incident. Systematic pressure has formed around allegations of insider trading involving Polymarket.

In February this year, Israeli authorities arrested and charged a reservist and a civilian, accusing them of profiting on Polymarket using confidential information regarding Israeli military actions against Iran.

In March, an account named "Magamyman" began betting about 71 minutes before the U.S.-Israel joint airstrike on Iran, ultimately profiting approximately $553,000.

Just yesterday, someone used a hairdryer to heat a temperature sensor near Charles de Gaulle Airport in France, thereby affecting the weather data reported by meteorological stations and profiting in the prediction market's weather predictions.

On Thursday, when President Trump was asked by reporters about this case at the White House, he stated that it was like Pete Rose betting on his own team to win. He then added that the world has regrettably turned into some sort of casino and expressed dissatisfaction with such bets in the prediction markets.

The compliance dilemma of prediction markets lies in the fact that Polymarket's international site operates on the Polygon blockchain and is set up outside the regulatory reach of the U.S., allowing users to access it via a VPN. Although the CFTC approved Polymarket to operate within the United States last year, its U.S. site has not yet fully launched.

The Trump family also has commercial ties to Polymarket. President's son Donald Trump Jr. serves as an advisor to Polymarket, and his venture capital firm 1789 Capital has invested millions of dollars in the platform.
