Will Section IV of the 25th Amendment be used during Trump's Presidency?
I think there is a meaningful but still minority chance that Section 4 of the 25th Amendment gets invoked during Trump’s presidency. The most likely outcome remains that it is not used, but the probability is higher than a trivial long shot because the mechanism can be triggered by acute incapacity, not just permanent removal.
Analysis
Section 4 of the 25th Amendment is an extraordinarily high bar in practice because it requires the vice president and a majority of the cabinet, or another body Congress designates, to conclude that the president is unable to discharge the powers and duties of the office. That means the event is not just about poor performance, scandal, or even major political conflict; it is about an elite-level consensus that the president cannot function. Historically, the amendment has never been used to remove a sitting president under Section 4, which keeps the base rate very low. Even so, the chance is not negligible over a full presidential term because the trigger can arise from sudden medical incapacitation, severe cognitive decline, or a discrete crisis that causes the cabinet and vice president to act quickly.
Trump-specific considerations cut both ways. On one hand, his presidency is highly polarized and frequently turbulent, which increases the chance of extraordinary institutional stress, staff turnover, or episodes that revive 25th Amendment discussion. On the other hand, invoking Section 4 against a sitting president is a dramatic, career-defining act for cabinet members and the vice president, and it would likely require an obvious and sustained incapacity rather than mere unpopularity or erratic behavior. If Trump remains politically active and able to communicate, the political incentive for his team to avoid such a move is strong. The biggest path to Yes is therefore not normal governance friction but a sudden medical or cognitive event that leaves little ambiguity.
Compared with the market price of 25%, my estimate is somewhat lower. I think the market is assigning a bit too much weight to general volatility and historical controversy without enough discount for the procedural and political hurdles involved in an actual Section 4 invocation. This is still one of those events where the tail risk is real, but the institutional threshold is so high that the default outcome remains No unless there is a clear, public incapacity episode.
Arguments
For
- Trump’s presidency is highly contentious, which increases the odds of an exceptional constitutional crisis.
- Section 4 can be used for temporary incapacity, so a brief but serious medical or cognitive episode could qualify.
Against
- The political and personal cost of invoking the 25th Amendment against a sitting president is enormous, so elites will hesitate until the case is overwhelming.
- There is no strong evidence here of an imminent incapacity event, and historical precedent for Section 4 being used is essentially nonexistent.
Key drivers
- Section 4 requires coordinated action by the vice president and a cabinet majority, making it very hard to trigger absent clear incapacity.
- The main plausible route to Yes is an acute medical or cognitive crisis that creates unmistakable inability to serve.
Risk factors
- A sudden health event or severe behavioral breakdown could force elite actors to act much faster than expected.
- Prolonged internal conflict or personnel changes could lower the threshold for a cabinet-led intervention if the situation deteriorates.
Scenarios
Best case
A clear medical or cognitive emergency leaves the vice president and cabinet with little choice but to invoke Section 4, making the answer Yes.
Most likely
The presidency remains volatile but functional enough that no formal Section 4 invocation occurs, despite periodic discussion and speculation.
Worst case
Trump remains able to perform the office throughout the term, and any controversy falls short of the constitutional threshold for incapacity.

How many Fed rate cuts in 2026?
AI11%MKT93%Edge-82HypedI think there is still a meaningful chance of at least one Fed cut in 2026, but the market is pricing in a very strong hold case for a reason. My estimate is that there is about an 11% chance of no rate cuts at all in 2026.

How many more Millennium Prize Problems will AI solve in 2026?
AI88%MKT19%Edge+69Hidden GemI think there is a strong chance that no qualifying Millennium Prize Problems will be counted for 2026 under this market’s rules, even though OpenAI’s Navier-Stokes claim makes the broader “AI solved a Millennium Problem” narrative look more plausible. The exclusion of Navier-Stokes from resolution is the key reason the zero-solved outcome still looks likelier than not.

Will OpenAI or Anthropic IPO first?
AI34%MKT95%Edge-61HypedMy independent view is that OpenAI is less likely than the market implies to be the first of the two to IPO. The current reporting tilt favors Anthropic moving earlier, and OpenAI’s process appears more valuation- and timing-constrained.
