**Strong presidential backing and the absence of viable removal pathways underpin the 76.5% trader consensus that Pete Hegseth will remain Secretary of Defense through December 31.** Despite Pentagon leadership turnover—including Army Secretary Dan Driscoll’s late-August resignation amid disputes over senior officer firings—and criticism from some Republicans over the ongoing Iran conflict and internal purges, President Trump has repeatedly expressed full confidence in Hegseth. Recent congressional efforts, such as Rep. Thomas Massie’s September impeachment resolution tied to war-powers concerns, lacked broad support and stalled ahead of recess. Hegseth continues to lead public initiatives, including homeland-defense advisory roles and defense-innovation events, with no scheduled confirmation fights or executive signals of change before year-end. The implied probability reflects trader assessment that only an unforeseen development, such as a major policy reversal or health event, would alter the current trajectory in the remaining months.
