Will the 25th Amendment be used during Trump's Presidency?

**Stage 1 — Blind Analysis (ignore market prices):**

*Basis and approach.* The 25th Amendment has two practically relevant uses: (a) Section 3, a voluntary, temporary transfer of power when a president is unable to discharge duties (commonly used for procedures requiring anesthesia), and (b) Section 4, an involuntary process initiated by the vice president plus a majority of Cabinet to declare the president unable, which is politically fraught and has never been used to permanently remove a president. My independent assessment treats both pathways separately and then combines them.

*Probability drivers.* For a president who is 79–80 years old (Donald Trump was born in 1946), the baseline probability of undergoing at least one medical procedure or episode over ~2.5–3 years that would justify a temporary transfer of power is materially higher than for a younger chief executive. In modern practice, Section 3 has been used multiple times in recent presidencies for routine procedures (temporary transfers occurred under Reagan-era administrations and were used by George W. Bush and by President Biden for brief procedures). Those precedents show that voluntary transfers are an established continuity mechanism; they are routine when anesthesia or incapacitating procedures are required.

*Assessment.* Given the age of the president, routine medical risks across the remainder of the term, and the well-established precedent and low institutional friction for Section 3 transfers for brief procedures, I view the chance of at least one invocation (most likely temporary) as substantially more likely than unlikely. By contrast, Section 4 removals require a rare confluence of severe incapacity, a VP/Cabinet willing to proceed, and likely political and legal battles; that pathway is far less likely (low single digits to low double digits percent).

*Combined independent probability.* Aggregating the plausible frequency of routine transfers plus a small tail for severe incapacitation yields my independent probability of ~60% that the 25th Amendment will be used at least once during Trump's presidency (predominantly Section 3 events).

**Stage 2 — Market Calibration (look at current market prices):**

The market price (Yes: 0.26, No: 0.74) is materially lower than my independent estimate. Possible reasons the market is pricing the probability this low:

- *Different interpretation of “used.”* Some traders may be interpreting the question narrowly as meaning a Section 4 involuntary removal attempt rather than any invocation (including routine Section 3 letters for medical procedures). If the market is focused on politically motivated removals, 26% is more plausible. - *Political-confidence heuristic.* Traders may overweight partisan realities — assuming the vice president and Cabinet will remain loyal, making any 25th use unlikely — and underweight medical/procedural use cases that historically trigger Section 3 transfers. - *Ambiguity and headline framing.* Public commentary emphasizing that the amendment is for “true incapacity, not partisan weaponization” (as in the supplied recent-news text) may have anchored traders toward a low probability by treating any invocation as illegitimate and hence unlikely. - *Risk aversion / house edge and liquidity effects.* With a substantial open interest (145,829 contracts), the market price may reflect risk-averse traders, stale positions, or conservative books rather than purely updated expected probability.

Given those market dynamics, I view the current price as mispricing the relatively high baseline likelihood of a voluntary Section 3 transfer. If you believe the market question includes Section 3 usage (which is how most plain-language readings of “used” are intended), the market underestimates the chance by a wide margin and presents a potential value opportunity to buy Yes. If, however, the market explicitly treats the question as only applying to Section 4 involuntary removal, the market price is closer to appropriate.

(Recommendation implicit in calibration: confirm the contract definition/FAQ to see whether Section 3 invocations count; if they do, the market looks underpriced relative to my 60% estimate.)
