Prediction markets put the probability at 30%: Will Robert F. Kennedy Jr. leave the Trump administration before 2027. Currently, markets see this as unlikely (30% YES). Insight: Warned off vaccine actions, Kennedy seeks quick health wins ahead of midterms | Reuters.
The probability that Robert F. Kennedy Jr. will leave the Trump administration before 2027 stands at 30% YES, reflecting mounting political and legal pressure on the Health and Human Services (HHS) secretary. A federal judge in Massachusetts on May 1, 2026 refused to halt a lawsuit challenging Kennedy’s decision to slash the number of recommended vaccines for children, allowing proceedings to continue while the Trump administration appeals the order blocking those moves. Simultaneously, a report released in early May from autism advocacy groups accused Kennedy of creating a “crisis of public trust” through misinformation, with calls for Congress to conduct oversight hearings and potentially pursue impeachment proceedings against the HHS secretary. These twin pressures—judicial and congressional—are the primary drivers behind the 30% probability that Robert F. Kennedy Jr. leave the Trump administration before the end of 2026.

The political calculus for Kennedy has shifted significantly as the November 2026 midterm elections approach. According to a Reuters insight report published May 4, 2026, the White House has warned Kennedy off further aggressive vaccine-related actions, instead directing him to pursue quick health wins—such as reviving the Presidential Physical Fitness Award—to bolster Republican candidates in the midterms. President Trump signed a proclamation on May 5, 2026 reintroducing the competitive fitness test in U.S. schools, with Kennedy standing beside him in the Oval Office. This strategic pivot suggests the administration views Kennedy as a liability on vaccine policy but still values his presence for base mobilization ahead of the election. However, the 70% NO probability indicates that market participants currently believe Kennedy will remain in his post through 2026, as his departure would risk alienating the anti-vaccine constituency that Trump courted during the 2024 campaign.

Looking ahead, the key procedural milestones that could trigger a change in Kennedy’s status include the ongoing vaccine lawsuit in Massachusetts, where a final ruling against the administration could force a policy reversal or a resignation. Additionally, the House Oversight Committee has yet to schedule hearings on the autism misinformation report, but sources indicate that bipartisan pressure is building for a vote on a resolution of inquiry into Kennedy’s conduct. If the committee votes to advance such a resolution before the August recess, it would mark the first formal step toward a potential contempt or impeachment process. The 30% YES probability reflects the possibility that Kennedy might preemptively resign to avoid a damaging public hearing, though the 70% NO baseline assumes he will weather the storm through the midterms, betting that election-year dynamics will shield him from removal.
