Will Section IV of the 25th Amendment be used during Trump's Presidency?
I assess a low chance that Section IV will be used against President Trump during his term — roughly a 12% probability — because the constitutional, political, and practical hurdles are very high and the current activity is mostly rhetoric and procedural bills, not an operational invocation.
Analysis
**Stage 1 — Blind analysis (ignore market price):**
- *Constitutional mechanics create a very high bar.* Section IV requires (1) the Vice President and a majority of Cabinet to submit a written declaration that the President is unable to discharge the powers and duties of the office, and (2) if the President contests, a Congressional decision within 21 days that requires a two-thirds vote in *both* the House and the Senate to sustain removal. That 2/3 requirement in each chamber is extremely difficult in a polarized era.
- *Historical precedent and institutional incentives cut strongly against use.* Section IV has never been used to remove a sitting president. Cabinet officers and a Vice President who initiate removal would be taking an extraordinary professional and political risk — likely ending their careers in the current partisan environment — unless there is overwhelming, nearly irrefutable evidence of incapacity or an immediate national-security crisis caused by the President’s actions.
- *Political reality of the current administration.* The available reporting shows no written declaration under Section III or IV as of July 2026, only proposals, calls, and a bill to create a commission. Those steps increase scrutiny but are not the constitutional trigger. Given the view that the Vice President (per context) and many Cabinet members are political allies or were appointed by the President, the default expectation is reluctance to initiate Section IV.
- *Paths that could plausibly produce a Section IV invocation are narrow but not zero.* A sudden and severe medical/neurological event that renders the President clearly incapacitated, or a rapid national-security emergency in which the President demonstrably refuses to act or is acting in ways assessed as dangerously incompetent, could compel a VP and sufficient Cabinet members to act despite the costs. Another path is a broad bipartisan collapse of confidence in the President among his own party's congressional leadership and Cabinet that produces both initiation and a supermajority in Congress.
- *Probability judgment (blind):* Given the immense constitutional and political hurdles, the absence of any written declaration as of this date, the unlikelihood of securing two-thirds in both chambers, and the small but real chance of an acute crisis that forces action, I estimate the independent probability that Section IV will be used during Trump's presidency at **~12%**.
**Stage 2 — Market calibration (considering current market price Yes: 27% / No: 73%):**
- The market price of 27% for "Yes" is materially higher than my independent assessment. Several plausible explanations for this divergence exist: - *Traders are overweighting political rhetoric and legislative proposals.* Calls by governors, individual Representatives, and bills to create commissions are salient and newsworthy; some traders may conflate these signals with imminent constitutional action, pushing up the price. - *Confusion between Section III and Section IV.* Markets may be pricing any 25th‑Amendment action (including voluntary, temporary transfers under Section III) rather than the specific congressional ratification mechanism of Section IV. Section III is a lower-friction mechanism (presidential voluntary transfer) and could be used for temporary incapacity; conflating the two inflates perceived Section IV probability. - *Event traders value tail-risk interventions.* Traders sometimes overprice low‑probability, high‑impact outcomes (political tail risks) especially around volatile presidencies. The 27% price reads like a precautionary premium for instability rather than a sober reading of the supermajority constraint. - *Information asymmetries and attention bias.* High media attention to proposals and to any perceived presidential incapacity increases market participation and can bias price away from fundamentals.
- I therefore conclude the market is likely mispricing the event to the upside. If one wanted to trade against the market, the structural obstacles (VP/Cabinet initiation + 2/3 in both chambers) and historical precedent support a lower fair value in the low teens (my 12%). That said, the market is not implausible if a sudden, acute crisis occurs — markets can rapidly reprice in that scenario, so the spread reflects both fundamental skepticism and fear of a black‑swan political event.
- Practical implication: current market price appears to overstate the probability of Section IV being used absent an extraordinary catalyst. If you believe no such catalyst is likely, the market offers value on the "No" side; if you believe an acute crisis is plausible, the market may be rationally pricing that tail risk.
Arguments
For
- There are active calls and legislative pushes (commissions and proposals) that raise public and institutional attention to presidential fitness.
- If the President were to take extreme, demonstrably dangerous actions (e.g., ordering unlawful military steps), the national-security imperative could compel VP and Cabinet action.
- A credible medical or neurological event making the President clearly unable to perform duties would produce a straightforward pathway for Section IV initiation.
- Persistent scandals or new revelations that erode intra-party support could flip enough lawmakers to reach supermajorities in Congress in exceptional circumstances.
- High visibility and pressure from state leaders and former officials could create political momentum to overcome individual career-risk calculations.
- The administration’s day-to-day instability increases the baseline probability of a crisis that would trigger constitutional remedies relative to a historically stable presidency.
Against
- Section IV has never been used and requires a two-thirds vote in both the House and Senate — an extremely high constitutional hurdle in a polarized era.
- Initiation requires the Vice President and a majority of Cabinet; those actors face severe personal and political costs, making initiation unlikely absent incontrovertible evidence.
- Current actions are largely rhetorical or procedural (commissions, bills), not written declarations under Section III/IV — the actual constitutional mechanism has not been engaged.
- If the Vice President is politically aligned with the President (as context implies), the chance the VP will lead an initiation is low.
- Successful use requires rapid bipartisan consensus within a narrow time window; the logistics and political negotiations make successful execution improbable.
- Legal and procedural ambiguity could slow or block removal even if initiation occurred, reducing the expected value of attempting Section IV.
Key drivers
- Willingness of the Vice President to join a Section IV declaration
- Number and identity of Cabinet members ready to sign (majority required)
- Objective, credible evidence of presidential incapacity or conduct threatening national security
- Congressional composition and willingness to assemble 2/3 votes in both chambers
- Public opinion and elite pressure (media, former officials) that could shift risk calculus
- Timing and nature of any acute crisis (health emergency, national-security catastrophe, or rapid political collapse)
Risk factors
- Misunderstanding or conflation of Section III (voluntary transfer) with Section IV (involuntary removal) among market participants
- Extreme partisan polarization that blocks any bipartisan supermajority even in severe cases
- Personal and career risks for Cabinet members and a VP that deter initiation of Section IV
- Legal ambiguity and potential court challenges that could complicate or delay the constitutional process
- The possibility of a sudden, low-probability crisis (medical, security) that materially increases probability on short notice
- Media-driven overreaction causing markets to overprice unlikely constitutional actions
Scenarios
Best case
A narrowly defined, acute crisis (e.g., a severe medical event rendering the President incapacitated or a sudden, demonstrable national-security catastrophe caused by the President) prompts the Vice President and a clear majority of Cabinet to submit the Section IV declaration; bipartisan outrage and clear, documented incapacity lead Congress to sustain the declaration with supermajorities. Section IV is used and the Vice President temporarily or permanently assumes the powers of the presidency.
Most likely
No invocation of Section IV. The term sees heightened scrutiny, commissions or investigations, and political pressure, but actual constitutional action does not occur. There may be temporary, voluntary transfers under Section III in limited medical situations (if any), but Section IV is not used because of the high initiation costs and the near-impossibility of securing two-thirds in both chambers.
Worst case
Political and institutional failure: despite multiple calls and a commission or high-profile allegations of incapacity, the Vice President and most Cabinet members refuse to initiate Section IV, or the President contests and Congress fails to achieve two-thirds in either chamber. The attempt either never reaches the constitutional trigger or fails in Congress, leaving the President in office and further polarizing the polity.

AI72%MKT28%Edge+44Hidden GemI assess a 72% independent probability that the average annual number of US measles cases across 2025–2028 will meet or exceed ~3,000 per year (i.e., the 'Yes' outcome). This reflects the strong acceleration in 2026, weak policy response, and high-risk pockets that make a sustained multi-year elevated average more likely than not.
