Trump out as President by July 31?

Platform comparison

Market context

Donald Trump’s resignation or removal from the presidency before 31 July 2026 is currently priced at a 1% implied probability on Polymarket, reflecting the crowd’s view that such an event is highly unlikely. This market resolves to “Yes” only if he permanently ceases to be president, with temporary invocations of the 25th Amendment not qualifying. The settlement window ends at 23:59 ET on 31 July 2026, and any public announcement of resignation or removal before that date immediately triggers a “Yes” outcome.

Historically, no US president has resigned or been removed before the end of their term since Richard Nixon’s 1974 resignation, and even then, it was voluntary amid impeachment proceedings. The closest comparable case is Andrew Johnson’s 1868 impeachment trial, which ended in acquittal. Current approval ratings for Trump’s second term sit at 38%, with satisfaction on the economy at 30% and inflation at 22%, per Marquette Law School data from May 2026[6]. While James Carville has predicted an exit by Easter 2027, that timeline falls outside this market’s window[2].

Traders should monitor the November 2026 midterm elections, which often negatively impact incumbent presidents[7], as well as any official statements from White House counsel or congressional leadership regarding fitness for office. Recent commentary from Salon questioned Trump’s health after the G7 summit, noting possible stroke symptoms[9]. On Polymarket, odds are decimal-based and update in real time, whereas Kalshi and Betfair use implied probabilities and may impose KYC restrictions or different fee structures, creating divergence in how this specific market is priced across platforms[1][4].
