**RFK Jr. remains U.S. Secretary of Health and Human Services more than a year after his narrow 2025 Senate confirmation, with traders pricing a 94.5% chance he stays through October 31, 2026.** Sustained presidential support from the White House underpins the consensus, as the administration continues advancing “Make America Healthy Again” priorities including vaccine schedule revisions, HHS reorganization, and leadership changes aligned with Kennedy’s directives. Despite Democratic congressional inquiries, calls for resignation from healthcare groups, court challenges to advisory committee appointments, and public criticism tied to measles outbreaks and agency actions, no removal process has advanced. Official statements and reporting show Kennedy actively directing policy and appearing at events into September 2026, with no announcements or procedural moves indicating departure before the resolution date.
