The White House press office typically issues a full lid once the president’s confirmed public schedule concludes with no further events, travel, or statements expected. For the August 31–September 5 window, trader probabilities (ranging 54–89% Yes across days) reflect an in-town or limited-travel schedule centered on executive time, Oval Office meetings, and policy signings, with lids historically called in the late afternoon when activities wrap by mid-evening. Proximity to the Labor Day recess and absence of major summits, overseas trips, or legislative deadlines support earlier closures, though any late announcements, tele-rallies, or unfolding developments could extend coverage past the 6:30 PM ET threshold. Resolution relies on Roll Call or Forth pool reports confirming the first explicit full lid timing.
