What moves the probability
Congressional control
Republicans hold both chambers through the current Congress, meaning any impeachment vote in the House lacks a clear path to the two-thirds Senate threshold needed for removal. This is the single largest factor keeping the price near zero, since it forecloses the most institutionally normal path to an early exit.
No active impeachment process
No impeachment inquiry has advanced to articles that could reach a Senate vote before 31 August 2026. Without that process already in motion, the short remaining window makes a removal within the deadline implausible on procedural grounds alone.
Resignation is discretionary
Only Trump himself can resign, and nothing in current public reporting suggests he intends to. The lone historical precedent, Nixon in 1974, followed conditions โ near-certain impeachment and conviction โ that are not present now.
25th Amendment threshold is narrow
A temporary Section 4 invocation, even for a documented medical or other incapacity, would not resolve this market Yes under its rules; only a sustained invocation upheld by two-thirds of both Houses qualifies. That is a higher bar than ordinary impeachment and has never occurred in US history.
Low but nonzero tail risk
The residual 1% likely reflects generic tail risk โ an unreported health event or unforeseen political shock โ rather than any specific process currently unfolding. Markets rarely price genuinely settled questions at exactly zero, leaving a small premium for the unexpected.
The case for
- A sudden, serious health event would need to incapacitate Trump in a way that triggers a sustained Section 4 invocation ratified by two-thirds of both the House and Senate before 31 August 2026.
- Alternatively, Trump would need to announce his own resignation, which under the rules would resolve the market Yes immediately even if the effective date came later.
- A third path would require the House to impeach and the Senate to convict by a two-thirds vote within the same three-week window, a sequence that has never happened in US history and shows no sign of being underway.
- Any of these would have to occur, or be announced, on or before 31 August 2026, 11:59 PM ET, for the contract to settle Yes.
The case against
- Republicans control both chambers of the current Congress, removing the realistic path to a two-thirds Senate conviction vote.
- No impeachment inquiry has produced articles of impeachment that could reach the Senate floor before the 31 August 2026 deadline.
- There is no public reporting indicating Trump intends to resign or that a 25th Amendment process is underway.
- The deadline is close enough, and current political conditions stable enough, that the market prices the outcome as close to settled rather than genuinely contested.
