The White House last month warned staff in an email not to make prediction markets bets related to the Iran war, a Trump administration official confirmed Friday.
The warning came amid increasing concern about insider trading on prediction markets such as Polymarket after a series of suspiciously timed trades around the Iran war, and on the U.S. ouster of Venezuelan President Nicolás Maduro earlier this year.
The Wall Street Journal first reported on the March 24 email to White House staff.
That email was sent a day after President Donald Trump announced a pause in hostilities in a post on the social media site Truth Social.
