NEW YORK (AP) — A U.S. special forces soldier is due in federal court in New York on Tuesday on charges that he used classified information about the mission to capture former Venezuelan leader Nicolás Maduro to win more than $400,000 on the prediction market Polymarket.
Gannon Ken Van Dyke, 38, has been charged 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.
The case comes during heavy scrutiny on prediction markets, which allow people to trade or wager on almost anything, as policymakers call for stricter regulation of the platforms amid concerns about insider trading.
Prosecutors said Van Dyke was involved in the planning and execution of Maduro's capture and had signed nondisclosure agreements centered on the operations, but he eventually placed a series of bets related to Maduro being out of power by Jan. 31.
Polymarket, one of the largest prediction markets, flagged the suspicious activity and turned it over to the government, according to CEO Shayne Coplan.
Van Dyke, who is stationed at Fort Bragg near Fayetteville, North Carolina, was granted bond after a court hearing in North Carolina last week and will continue his case in New York. Court records did not list an attorney for him in New York.
The Trump administration has been supportive of the prediction market industry's expansion. The president’s eldest son is an adviser for both Polymarket and its main competitor, Kalshi, and he is a Polymarket investor. Trump’s social media platform, Truth Social, is launching its own prediction market called Truth Predict.

WIENER NEUSTADT, Austria (AP) — The trial against a man accused of pledging allegiance to the Islamic State group and plotting to attack one of superstar singer Taylor Swift’s concerts in Vienna nearly two years ago has begun in Austria.
The plot was thwarted, but Austrian authorities still canceled Swift's three performances in August 2024. The singer's fans, known as Swifties, who had flown to Austria from across the globe to attend a performance of her record-setting Eras Tour were devastated, but rallied to turn Vienna into a citywide trading post for friendship bracelets and singalongs.
The defendant, a 21-year-old Austrian citizen known only as Beran A. in line with Austrian privacy rules, faces charges including terrorist offenses and membership in a terrorist organization. He could be sentenced to up to 20 years in prison.
He is facing trial alongside Arda K., whose full name also has not been made public. They along, with a third man, planned to carry out simultaneous attacks in Saudi Arabia, Turkey and the United Arab Emirates during Ramadan in 2024 in the name of the Islamic State group. Beran A. and Arda K. never carried out their attacks.
Beran A.'s defense attorney, Anna Mair, on Monday told The Associated Press that her client plans to plead guilty to most of the charges but she did not specify which ones. Only Beran A. is charged in connection with the Taylor Swift plot.
He allegedly planned to target onlookers gathered outside Ernst Happel Stadium — up to 30,000 each night, with another 65,000 inside the venue — with knives or homemade explosives. The suspect hoped to “kill as many people as possible,” authorities said in 2024. The U.S. provided intelligence that fed into the decision to cancel the concerts.
Beran A. also allegedly networked with other members of the Islamic State group ahead of the planned attack. Prosecutors say they discussed purchasing weapons and making bombs, and that the defendant also sought to illegally buy weapons in the days ahead of the performance. In addition, he swore allegiance to the militant group.
Authorities searched his apartment on Aug. 7, 2024 and found bomb-making materials. The concerts were scheduled to begin the next day.
“Having our Vienna shows cancelled was devastating,” Swift wrote in a statement posted to Instagram two weeks later. “The reason for the cancellations filled me with a new sense of fear, and a tremendous amount of guilt because so many people had planned on coming to those shows.”
The trial is being held in Wiener Neustadt, about an hour south of Vienna. The proceedings are set to continue May 12.
Prosecutors have also filed terrorism-related charges against Arda K. in the trial in connection with the plan for simultaneous attacks in Saudi Arabia, Turkey and the United Arab Emirates.
The third man in that plot, Hasan E., allegedly stabbed a security guard with a knife at the Grand Mosque in Mecca, Saudi Arabia, on March 11, 2024. He was arrested and remains in pretrial detention in Saudi Arabia, Austrian prosecutors said.
Beran A. and Arda K. did not carry out their plans in Turkey and the UAE. Beran A. returned to Vienna and then allegedly began plotting to attack a Swift concert there.
The Vienna plot drew comparisons to a 2017 attack by a suicide bomber at an Ariana Grande concert in Manchester, England, that killed 22 people. The bomb detonated at the end of Grande’s concert as thousands of young fans were leaving, becoming the deadliest extremist attack in the United Kingdom in recent years.
