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

Based on the information provided, the strongest case for a Yes outcome is that the amendment has already been openly discussed in prior Trump crises and has resurfaced again in 2026 after renewed controversy, which suggests the possibility is not purely theoretical. Section 4 is designed for a formal incapacity declaration by the vice president and a Cabinet majority, and the reporting makes clear that political actors have at least periodically considered that route when Trump’s behavior or decisions have triggered alarm.

The main case against Yes is structural: the amendment requires the vice president plus a majority of principal executive officers to certify incapacity, and every source provided emphasizes how unlikely that coalition is to form against Trump. Even if public pressure rises, the process is reversible, contested, and politically explosive, which raises the bar further because would-be participants must accept immediate confrontation with the president and the risk of a failed constitutional showdown. That makes invocation much less likely than casual headlines or congressional calls might suggest.

Relative to the current market price of 30% Yes, I think the market is somewhat low but not dramatically wrong. A 38% independent probability reflects that the event is still unusual and difficult, but not remote given the remaining time in Trump’s presidency and the possibility of a sharp crisis that changes elite incentives. The market may be underestimating how quickly a serious military, health, or constitutional emergency could create the conditions for a Section 4 attempt, while still correctly recognizing that the default outcome is No.
