Will the 25th Amendment be used during Trump's Presidency?
I assess an 18% independent probability that the 25th Amendment will be invoked at least once during Trump’s presidency (2025–2029) in any section (temporary transfer, involuntary declaration, or replacement). This reflects routine medical-transfer risk plus a small chance of an extraordinary political/medical crisis, weighed against very high institutional hurdles and historical precedent.
Analysis
**Stage 1 — Blind analysis (ignore market prices)**
The 25th Amendment has three operational flavors: (1) Section 3 voluntary transfers (president temporarily cedes power), (2) Section 4 involuntary transfers initiated by the vice president plus a majority of Cabinet, and (3) succession on death or resignation. Historically, Section 3 has been used a handful of times for routine medical procedures; Section 4 has never been used to remove a president.
Key facts: the mechanism requires either the president's assent (Section 3) or coordinated action by the vice president and a majority of principal Cabinet officers (Section 4). The Amendment is not designed as a political censure tool but for incapacity. Trump is older than many recent presidents, increasing baseline medical risk over a four-year term; however, acute, incontrovertible incapacity that would trigger a Cabinet/VP Section 4 declaration is rare. Trump’s governing style favors loyalty in personnel choices (including VP and Cabinet), lowering the chance of a revolt among those who would have to invoke Section 4.
Weighing probabilities: routine, voluntary, temporary uses (Section 3) — e.g., a surgical procedure requiring anesthesia — are credible and not uncommon in modern presidencies (Reagan, George W. Bush, Obama, Biden have all briefly transferred power). Trump did not do this in his first term, but that may reflect circumstances, not inability. I estimate the chance of at least one voluntary, temporary transfer over a four-year term at roughly 12–15% given age and baseline medical-care patterns.
Involuntary removal (Section 4) — the historically unprecedented scenario — is far less likely because it requires the VP plus majority of Cabinet to agree that the president is unable to discharge duties. Given the political costs, the high evidentiary threshold in practice (visible, compelling incapacity), and Trump's expected control over appointments and the vice presidency, I place the chance of a Section 4 invocation at roughly 1–3% over the term. Combined, this leads to an overall independent probability in the high-teens range.
**Stage 2 — Market calibration (use current market prices)**
The market currently prices "Yes" at ~25% (No 75%). That is meaningfully above my independent estimate of 18%. Possible reasons the market is higher:
- Many traders likely interpret "used" to include *any* invocation (including brief, routine Section 3 transfers during planned medical procedures). Some bettors may view such routine transfers as likely and thus push price up. - The market may overweight salient political narratives (frequent 25th Amendment commentary about Trump in the media) and rare but high-consequence tail events (e.g., sudden incapacitating stroke, assassination attempt with survival but incapacitation, or a dramatic public-health crisis) that would force action. - Liquidity and concentrated positions: this market shows substantial volume; partisan or attention-driven participants sometimes overbet low-probability/high-salience outcomes.
Why my estimate is lower than the market:
- I separate routine medical transfers from involuntary political removals, and I assign low probability to Section 4 because of high institutional resistance and the need for coordinated action by sufficiently loyal officials. If the market assumes Section 4 is more likely, it may be overpricing political risk. - The market may not sufficiently discount the historical precedent (never used involuntarily) and Trump’s likely control of senior appointments, which materially lower the chance of Cabinet-led action.
In summary: I think the market is modestly pessimistic (i.e., overprices the chance the 25th Amendment will be used), but not wildly off if participants are counting routine short-term transfers. If you interpret "used" narrowly as an involuntary removal (Section 4) the market is substantially overpricing that path. If the market’s intended interpretation includes ordinary Section 3 transfers, the market price is closer to a reasonable range but still slightly high relative to my calibrated estimate.
Arguments
For
- Age and medical risk: Trump will be an older president and age increases the baseline probability of medical procedures or acute events that lead to use of Section 3 or prompt questions about fitness.
- Routine medical procedures: presidents commonly use Section 3 for brief transfers during anesthesia — this is a plausible and relatively low-friction path for the Amendment to be 'used.'
- Unpredictable acute events: accidents, strokes, or other health crises could produce an observable incapacitation that forces action by the VP and Cabinet.
- High public and media attention: intense scrutiny could create pressure on the VP/Cabinet to act if credible evidence of incapacity appears.
- Congressional pressure: while Congress cannot directly trigger Section 4, intense legislative and public pressure could influence executive-branch principals to initiate the process.
- Legal avenues for additional bodies: Congress could, by law, create a body to act under Section 4, potentially lowering the threshold if such a law were passed (unlikely but possible).
Against
- High institutional hurdle: Section 4 requires the vice president plus a majority of principal officers of executive departments — coordination and willingness to act are major barriers.
- Historical precedent: Section 4 has never been invoked to remove a president; norms and legal hesitation weigh heavily against its use.
- Political loyalty: Trump’s likely selection of a loyal VP and loyal Cabinet members reduces the probability they would initiate or join an involuntary transfer.
- Alternative mechanisms: impeachment, resignation, or ordinary succession on death are available political/legal mechanisms that may be preferred over the 25th for non-medical issues.
- Evidence standard and political cost: proving the president is unable to discharge duties in a way that persuades a majority of Cabinet (and withstands public/political backlash) is difficult.
- Death or clear incapacitation leading to succession bypasses the need for a 25th invocation; in many severe outcomes the Amendment is unnecessary and thus not 'used.'
Key drivers
- Vice President loyalty and likelihood to initiate or join a Section 4 action
- Cabinet composition: number of loyalists vs. independent officials willing to declare incapacity
- President’s health trajectory and likelihood of procedures requiring anesthesia (driving voluntary Section 3 transfers)
- Public visibility and evidentiary clarity of any incapacitating event (stroke, severe neurological illness, accident)
- Political costs and career risk to Cabinet/VP members of invoking Section 4
- Media and public pressure dynamics that could force or deter action
Risk factors
- Ambiguity in what counts as “used” (temporary Section 3 vs. involuntary Section 4) — market and bettors may conflate them
- Low historical precedent for involuntary invocation (Section 4 never used), which structurally lowers baseline probability
- Potential for misreporting or slow disclosure of medical facts, delaying any action until ambiguity persists
- High coordination requirement among Cabinet principals makes timely action improbable
- Alternative political pathways (impeachment, resignation) that could be used instead of the 25th Amendment
- Changes in personnel (new VP or Cabinet members midterm) that could either raise or lower the chance unexpectedly
Scenarios
Best case
Brief, voluntary use: The president undergoes a routine medical procedure requiring anesthesia during the term, voluntarily transfers power under Section 3 for a short period, and later resumes duties. This satisfies the question’s broad interpretation and is the most plausible path to a 'Yes.'
Most likely
No involuntary removal, but a non-negligible chance (~12–15%) of a voluntary, temporary Section 3 transfer for medical reasons. Combined with a small (1–3%) tail risk of a Cabinet/VP Section 4 action under a dramatic medical or political crisis, the overall probability is in the high-teens (my estimate 18%).
Worst case
No invocation at all: No surgeries or other temporary incapacitating medical events occur, and no Cabinet/VP action is taken even if concerns arise. Any serious problem results in resignation or death (succession) rather than a formal 25th Amendment invocation — outcome: 'No.'

Who will Trump pardon?
AI8%MKT42%Edge-34HypedI assess a low probability that Barron Trump will receive a presidential pardon before Jan 21, 2029 — roughly 8% — because there is no public legal exposure for him and pardoning an immediate family member is politically costly and rare, though nonzero because presidential clemency is broad and Trump has signaled willingness to use pardons expansively.
