Before White House press secretary Karoline Leavitt takes the podium for press briefings, users on Polymarket and Kalshi place their bets, hoping to cash in on their predictions about when the briefing will start, how long it will last and what Leavitt will say.

Words and phrases like “ICE,” “narco-terrorist,” “Biden,” and “radical left” are popular picks, with thousands of dollars being put up every time she takes the podium. Users have placed about $33,000 on whether the UFC will host a fight at the White House by the country’s 250th anniversary, $85,000 on what President Donald Trump will say in his State of the Union address, and $372,000 on which Cabinet secretaries will be out by the end of the year.

Earlier this month, Leavitt made headlines for ending the briefing seconds before users could cash in bets that it would last longer than 65 minutes.
