Will Section IV of the 25th Amendment be used during Trump's Presidency?
I think Section 4 of the 25th Amendment is possible but still unlikely during Trump’s term. My independent estimate is lower than the market because the legal and political hurdles are enormous, and even a serious health or incapacity episode would more likely lead to a voluntary Section 3 transfer or some other resolution than a successful Section 4 invocation.
Analysis
The core issue is not whether Trump might face controversy, medical concerns, or political conflict; it is whether the vice president and a majority of the Cabinet would actually move to declare him unable to serve, and then withstand the inevitable political backlash. That is an extraordinarily high bar, and Section 4 has never been successfully used in U.S. history. The historical record suggests that even in periods of intense constitutional stress, officials have been reluctant to trigger a mechanism that amounts to an intra-executive removal of a sitting president.
Trump’s age and the possibility of future health deterioration create a real, nontrivial tail risk, and the remaining horizon is long enough for unexpected events. Still, the more likely response to a short-term incapacity would be Section 3, which is voluntary and far less politically explosive. For Section 4 to happen, there would likely need to be a severe, obvious, and sustained incapacity combined with a cabinet willing to break with the president, which is especially hard under a loyalty-heavy administration.
The current market price of 30% looks high relative to those institutional constraints. Public discussion of the 25th Amendment, recurring concerns about Trump’s fitness, and the sheer amount of time left until the end of the term can make invocation feel plausible, but most of that noise does not translate into actual cabinet action. I think the market is overweighting headline risk and underweighting the near-impossibility of assembling the required coalition against a sitting president, so my estimate is meaningfully below the current price.
Arguments
For
- There is a meaningful chance of a serious health or incapacity episode over a multi-year horizon.
- If Trump became clearly unable to function and resisted stepping aside, Section 4 is the constitutional tool designed for that situation.
Against
- Section 4 has never been successfully used, showing how difficult it is to operationalize in practice.
- A loyal Cabinet and the political costs of removing a sitting president make the required coalition hard to assemble.
Key drivers
- Section 4 requires the vice president plus a majority of the Cabinet, making it much harder than ordinary political pressure or criticism.
- Trump’s advancing age and the long remaining time in office create a real chance of some qualifying incapacity event before 2029.
Risk factors
- A sudden, severe medical or cognitive crisis could make a Section 4 move politically unavoidable.
- If a major internal rupture emerges in Trump’s Cabinet or with the vice president, the probability could rise quickly from a low base.
Scenarios
Best case
Trump suffers a clear incapacity or prolonged medical crisis, the vice president and Cabinet conclude he cannot continue, and Section 4 is invoked and sustained.
Most likely
There are recurring debates, rumors, or health concerns, but no successful Section 4 invocation because the required political coalition never forms.
Worst case
Trump remains in office without any qualifying incapacity that triggers a serious removal effort, or any temporary transfer is handled under Section 3 instead.

How many Emmys will “DTF St. Louis” win?
AI41%MKT98%Edge-57HypedDTF St. Louis has enough nomination strength and category-level upside that a 2-plus win outcome is very live, so I do not think the 0-or-1 bracket is close to certain. My read is that 0 or 1 wins is a modest underdog relative to the market price, not a near-lock.
