White House Press Secretary Karoline Leavitt's inconsistent arrival patterns at recent briefings drive the even trader consensus, with probabilities clustered at 34-37% across time bins amid no dominant recent delay. Her March 30 briefing on Iran negotiations and March 25 session started near schedule, but February instances featured 10-20 minute tardiness excused by technical issues or monitoring other press events, balancing sentiment without skewing toward punctuality or extended waits. Unpredictable White House scheduling, executive priorities, or competing announcements maintain the tight race. An early X post confirming the next briefing time or absence of foreign policy escalations could boost <15 or 15-20 minute odds, while last-minute crises might elevate 25+ minute shares.
