Health and Human Services Secretary Robert F. Kennedy Jr. remains securely in his role over a year after his narrow 52-48 Senate confirmation in February 2025, driving trader consensus to a 75.5% implied probability against his departure by December 31. His April 16 testimony before House Ways and Means and Appropriations committees—defending Make America Healthy Again (MAHA) reforms, proposed budget cuts, and agency restructuring amid Democratic scrutiny on vaccines, staffing, and Medicaid—signals ongoing stability despite prior February staff shakeups and resignation calls from critics. Absent official resignation signals, dismissal threats, or scandals, traders view his position as resilient through year-end fiscal battles and 2026 midterms.
