Source: James Comer The “suspiciously timed trades” to which Comer was referring included those from a May 13 New York Times report, detailing incidents of prediction market users betting on Israel’s military actions against Iran, US President Donald Trump announcing a ceasefire in the country’s war with Iran and event contracts related to congressional elections. Polymarket said in March that it had updated its approach to potential insider trading on the platform, while Kalshi announced in April that it had banned three US politicians for betting on their own races.

In April, the US Justice Department announced a criminal indictment against Master Sergeant Gannon Ken Van Dyke, a soldier who was involved in the military operation that led to the capture of Venezuelan President Nicolás Maduro. Prosecutors alleged that Van Dyke used event contracts on Polymarket related to Maduro’s capture to profit by more than $400,000 using classified information. Van Dyke pleaded not guilty to the charges, which included commodities fraud and the unlawful use of confidential government information for personal gain. He was released on $250,000 bail and limited to traveling between areas of North Carolina, California and New York.
