Will Section IV of the 25th Amendment be used during Trump's Presidency?
I put the chance of the 25th Amendment being used during Trump's presidency at 13%. A temporary or procedural transfer is possible, but a true Section 4 invocation remains very unlikely given the political and institutional hurdles.
Analysis
The core issue is not whether there could be moments of illness, travel, or routine incapacity; it is whether the amendment would actually be formally used in a way that meets the market's resolution standard. Section 4 is extraordinarily hard to execute because it requires the vice president and a majority of the cabinet to break with the president, and if contested it then faces an even steeper congressional barrier. With Trump's current political ecosystem and cabinet incentives, the threshold for a successful Section 4 episode is far higher than general public commentary suggests.
There is still some nontrivial chance of a 25th Amendment event because Trump will be older throughout the remainder of the term, and any administration with an aging president carries some probability of a medical emergency, procedure, or temporary incapacity. If the market were resolving on any invocation of the amendment, including a short Section 3 transfer during a medical procedure, the probability would be meaningfully higher. But the provided context points to Section 4 specifically, and on that narrower reading the historical base rate, the lack of any active process, and the political cost of initiating removal all push the odds down sharply.
Compared with the current 31% market price, I think the market is too optimistic about the likelihood of a qualifying invocation. That price makes sense if traders are loosely pricing in any 25th Amendment usage or simply the general possibility of health-related disruption, but it appears rich for an actual Section 4 event that survives the full constitutional and political gauntlet. The most likely outcome remains no formal invocation at all, with any temporary incapacity handled informally or through a brief, uncontested transfer if it happens at all.
Arguments
For
- Trump's age and the length of the remaining term create a real chance of a medical event or short-term incapacity.
- If a serious health or cognitive deterioration became undeniable, institutional pressure could make a formal 25th Amendment step more plausible.
Against
- Section 4 is nearly impossible without cooperation from the vice president and a majority of the cabinet.
- There is no evidence of an active removal process, and public calls for invocation are not the same as an actual invocation.
Key drivers
- Section 4 requires coordinated defection by the vice president and a cabinet majority, which is politically rare.
- Trump's age and the possibility of an unexpected medical or cognitive event keep the probability above zero.
Risk factors
- The market could resolve more broadly than expected if a temporary Section 3 transfer is counted as use of the amendment.
- A sudden severe health crisis or an acute incapacity episode could force officials to act despite political reluctance.
Scenarios
Best case
A major medical or cognitive event emerges, the vice president and cabinet act, and the amendment is formally triggered in a way that meets the market's definition.
Most likely
No Section 4 invocation occurs, and any health-related issues are managed through ordinary presidential staffing or, at most, a short uncontested transfer that may not count for this market.
Worst case
Trump remains in office without any formal 25th Amendment action, and any brief absences are handled without invoking the amendment.

"Spider-Man: Brand New Day" total domestic gross by August 31? (Higher Strikes)
AI25%MKT84%Edge-59HypedMy read is that Spider-Man: Brand New Day is more likely to finish above 900M domestically by August 31 than below it. I put the chance of less than 900M at about 25%, because the film is already so far along that only an unusually sharp slowdown would keep it under the line.
