Trump “not happy” with prediction markets – says world is a “casino” as Special Forces soldier arrested for insider trading on Polymarket

Federal prosecutors have charged U.S. Army Special Forces master sergeant Gannon Ken Van Dyke with using classified information regarding a military operation to profit over $400,000 on Polymarket. The case has sparked significant debate regarding the integrity of crypto prediction markets, as it highlights the challenge of maintaining fair pricing when traders possess nonpublic, sensitive government data. In response to the news, Donald Trump expressed his disapproval of prediction markets, characterizing the world as a "casino." While Polymarket stated it cooperated with investigators to report the suspicious activity, the incident forces the industry to confront the urgent need for better real-time surveillance and market design to prevent insiders from exploiting private information.
