President Trump announced Monday he will attend this year's White House Correspondents' Dinner, marking the first time he will do so as president. The market response was immediate and dramatic — odds of Trump attending any White House Correspondents Dinner rocketed to 90¢ from just 27¢, a massive 63¢ swing.

The timing is telling. The event is scheduled for April 25, and Trump's reversal comes amid broader efforts to reset his relationship with the press corps. This year, WHCA President Weijia Jiang selected mentalist Oz Pearlman to perform, bypassing a comedian who may have triggered controversy — a strategic choice that may have influenced Trump's decision. The market had long priced in Trump's consistent boycott pattern, making yesterday's announcement a genuine shock to traders who are now repricing presidential attendance as nearly certain.
