Trump out as President by July 31?

Platform comparison

Market context

Donald Trump resigning or being removed from the presidency before 31 July 2026 remains a remote possibility, with the current crowd-implied probability at just 1% for “Yes”. This figure reflects the structural hurdles of US constitutional removal: no president has ever been successfully removed via the 25th Amendment, and impeachment requires a two-thirds Senate majority—67 votes—which Democrats currently lack. Historical precedents, including Nixon’s resignation and Clinton’s impeachment, show that removal typically follows overwhelming political consensus or personal scandal, neither of which is currently evident at the scale required to shift odds from 1% to a tradable level.

Traders should monitor upcoming House votes on impeachment resolutions, Cabinet statements on presidential fitness, and any public health disclosures that might trigger 25th Amendment discussions. Recent reports suggest House Democrats are “two votes away” from advancing removal efforts, though this claim lacks official confirmation and remains speculative [2]. Meanwhile, Kalshi’s related market on Trump’s impeachment by end of 2026 shows a 28.7% probability, significantly higher than the 4% on Polymarket for the same event [1][3], highlighting divergent risk assessments between platforms. Polymarket’s “Trump out before 2027” market sits at 8%, further underscoring how fee structures, KYC thresholds, and liquidity depth shape implied probabilities across exchanges.
