GoKawiilAn anonymous reader quotes a report from Wired: The Department of Justice announced Thursday that it arrested Gannon Ken Van Dyke, an enlisted member of the US Army's special forces, for allegedly using "classified, nonpublic" information about the capture of Venezuelan president Nicolas Maduro to notch more than $400,000 in profits on Polymarket trades. A grand jury indicted him on five counts, including multiple violations of the Commodity Exchange Act. Van Dyke is the first person to be charged with insider trading on a prediction market in the United States. Lawmakers have been voicing concerns for months about the high likelihood that politicians and public servants could use nonpublic information to profit from trades on leading industry platforms like Polymarket and Kalshi, which have exploded in popularity over the past year. The arrest comes just weeks after Department of Justice prosecutors met with Polymarket about potential insider tradition violations. [...] After Van Dyke's arrest was made public, Polymarket posted a statement to social media noting that it had "identified a user trading on classified government information" and "referred the matter to the DOJ & cooperated with their investigation." The company declined to comment further. According to court documents, Van Dyke has been an active duty US soldier since September 2008 and rose to the level of master sergeant in 2023. At the time of the alleged trading activity, he was stationed at Fort Bragg in Fayetteville, North Carolina and assigned to the Army's Special Operations Command Western Hemisphere Operations. [...] The complaint alleges that Van Dyke was involved in the planning and execution of Maduro's arrest and that he was aware that he wasn't authorized to share nonpublic information about US military operations. The complaint says that Van Dyke signed a nondisclosure agreement that forbade him from revealing sensitive or classified government information "by writing, word, conduct, or otherwise." The complaint also alleges Van Dyke saved a screenshot to his Google account "displaying the results of an artificial intelligence query" outlining how the US Special Forces maintains many classified files including "operational details that are not available to the public." [...] Van Dyke faces a maximum sentence of 60 years if convicted on all counts.
