Who will leave Trump's Cabinet next?
I assess Robert F. Kennedy Jr. is the single most likely next Cabinet departure (independent probability ~34%) because his profile combines high public controversy, substantive policy conflicts with powerful institutions (FDA, public health community), and a track record of friction inside the administration — although the market is not far off and may be underpricing those risks.
Analysis
**Stage 1 — Blind analysis (ignore market prices):**
Robert F. Kennedy Jr. (HHS Secretary) is a uniquely high-profile, high-friction Cabinet member. He entered the role with an explicit agenda to overhaul the FDA and a public history of positions (vaccines, public-health skepticism) that have repeatedly put him at odds with the medical establishment and many Democrats and Republicans in Congress. Since confirmation he has been the subject of multiple public critiques, and there are documented feuds with influential figures such as Senator Bill Cassidy. Those features increase both the political pressure on him and the probability of a forced exit or voluntary resignation precipitated by scandal, policy failure, or an irreconcilable clash with senior White House advisers.
Factors that push his likelihood up: he is high visibility (departure creates large media shock if it happens), his policy agenda can produce tangible negative outcomes (e.g., a public-health incident tied to HHS action), and he has been the target of organized, vocal opposition from public-health groups and some Republicans. Factors that push his likelihood down are: presidents often tolerate or even protect allies who share core political narratives; removal of a Cabinet secretary requires either strong political will from the President or an independent trigger (scandal, health crisis) that forces a change; and institutional inertia — many Cabinet exits occur around administration shakeups, which may or may not be imminent.
Comparing him to the listed contenders: Susie Wiles, Pete Hegseth, Brooke Rollins, and Howard Lutnick occupy different risk profiles. Wiles (a senior political operative/advisor) is exposed to firing for political or managerial reasons, but advisors are sometimes shuffled quietly and are less likely to attract the drama that makes them the “next” named Cabinet departure in public markets. Hegseth is a noisy public figure whose rhetoric and management could generate controversy that forces a removal, particularly if tied to a veterans or VA scandal. Rollins (a policy council/ adviser-type role) has lower public visibility and thus lower immediate risk of being the next exit. Lutnick’s listing suggests some prior churn or exposure, but available records do not show the same level of sustained public conflict as RFK Jr.
Balancing these points, ignoring current market prices, I estimate Robert F. Kennedy Jr. has the single highest standalone probability of being the next person to leave the Cabinet because his combination of public profile, policy conflict, and active adversaries produces a higher hazard rate than the other named contenders.
**Stage 2 — Market calibration (after viewing market prices):**
Current market: Yes (RFK Jr.) = 27%. My independent probability is 34% — meaning I view the market as modestly underpricing RFK Jr.’s risk. Possible reasons the market price is lower:
- Ambiguity over who counts as “Cabinet” and the phrasing "next person to leave Trump's Cabinet" can favor lower-profile advisor exits. Traders may be splitting probability across many low-visibility aides and not giving high weight to high-profile removals, which underweights RFK Jr. - The market may be reacting to Trump’s historical tendency to keep or publicly defend controversial allies, assigning a premium to survival for close-aligned figures. - Some traders could be focused on higher near-term turnover among non-Cabinet-adjacent personnel (press people, deputies) that don’t necessarily show up in the top-contender list but reduce the chance any single named top contender is next. - Finally, liquidity and crowd composition matter: high retail participation can pull probabilities toward focal numbers rather than cold assessment of political risk.
Why I still favor trading RFK Jr. above the market price: the asymmetric risk of a high-profile health-policy failure or an escalated public feud leading to a quick resignation/firing is material and may happen with little lead time. If you believe a major policy misstep, public-health incident, or effective congressional pressure is plausible in the coming months, the current 27% price looks cheap relative to a 34% hazard I estimate.
Comparative calibration across contenders: markets give RFK Jr. the largest single share (27%), but they concentrate substantial remaining probability in many smaller names. I raise the probabilities of Susie Wiles and Pete Hegseth relative to the market because political operatives and loud public figures frequently become the subject of sudden exits (either direct dismissal or quiet removal) during midterm/advisory reshuffles. I keep Brooke Rollins and Howard Lutnick lower than RFK Jr. but non-negligible; Rollins is likely to be insulated by lower visibility, and Lutnick lacks the sustained, public-facing policy conflict that makes RFK Jr. a top hazard.
Bottom-line calibration: market is close to my view but probably slightly underweighting RFK Jr.’s tail risk. I place RFK Jr. at 34% to be the next Cabinet departure, with material probabilities assigned to Wiles and Hegseth as the next-most-likely exits.
Arguments
For
- High public profile and sustained controversies make RFK Jr. a lightning rod whose missteps or an adverse public-health outcome could force a rapid resignation or firing.
- Documented feuds (e.g., with Senator Bill Cassidy) and criticism from public-health organizations create organized pressure that can escalate into a removal campaign.
- His ambitious agenda to restructure the FDA puts him in direct institutional conflict with entrenched bureaucracies and key stakeholders whose resistance can generate public failures or scandals.
Against
- Presidential protection: the President often defends or tolerates controversial allies, reducing the short-term removal probability for politically aligned figures.
- Many Cabinet departures occur in waves during predictable reshuffles rather than as single-event removals; if the administration delays a broad reshuffle, RFK Jr. may outlast lower-profile aides.
- A high-profile exit could produce negative optics for the administration at sensitive political moments, creating incentives to retain him unless an extreme trigger occurs.
Key drivers
- Public visibility and sustained controversy around RFK Jr.'s positions and policy agenda (FDA overhaul, vaccine skepticism).
- Institutional friction with Congress and public-health stakeholders (feuds, public accusations).
- Trump's propensity to defend or remove loyal but politically risky aides — presidential preference can accelerate or delay exits.
- Timing of shocks (a public-health incident, high-profile policy failure, or intense congressional pressure) that could precipitate a rapid exit.
Risk factors
- Ambiguity in who traders consider 'Cabinet' — inclusion of non-statutory advisors increases market noise.
- Presidential tolerance — Trump may prefer to keep controversial figures who buttress his political objectives.
- The unpredictable timing of policy shocks — the next departure could be any sudden personnel change anywhere in the administration.
- Information gaps — private negotiations, behind-the-scenes deals, or health/personal reasons could cause exits unrelated to public controversies.
Scenarios
Best case
For the 'Yes' outcome (RFK Jr. is next): A policy-driven crisis or a public-health incident linked to HHS action (or an intensifying, high-profile clash with key senators) erupts in the near term. Media scrutiny and bipartisan pressure become intense; the President decides the political cost of keeping RFK Jr. is too high and either forces a resignation or effectuates a dismissal. The exit is public, rapid, and operates as the next named Cabinet departure.
Most likely
A politically-driven, moderately public departure occurs within the next 12–18 months. RFK Jr. is the single most likely named Cabinet member to leave next, but the race is competitive: an abrupt political or managerial misstep could instead make Susie Wiles or Pete Hegseth the next exit. The administration likely manages the optics carefully; if removal occurs it will be preceded by escalating public criticism and internal pressure.
Worst case
For the 'No' outcome (RFK Jr. is not next): The President privately shields RFK Jr., or the next departure is a lower-profile advisor or deputy with more immediate operational failures. No single scandal implicates HHS before a planned personnel reshuffle, and RFK Jr. remains in office until a later, less-predictable time. The next exit ends up being a different public-facing figure (e.g., a political advisor) whose departure is less consequential but occurs sooner.
