**RFK Jr. serves as HHS Secretary with strong ongoing White House support, driving the 92.5% implied probability he remains in office through October 31, 2026.** He continues advancing MAHA priorities, including vaccine schedule revisions, agency reorganizations, staff reductions, and leadership changes at HHS components. President Trump has repeatedly backed these efforts despite Democratic congressional inquiries, calls for resignation from medical groups and former staff, and court challenges to certain policy shifts. No resignation, removal, or qualifying departure has occurred or been signaled in recent months, and Kennedy remains active in announcements and Senate testimony. Traders view sustained executive alignment and absence of triggering events as outweighing opposition pressures.
