What this market actually measures

This market will resolve to “Yes” if Donald Trump resigns or is removed as President or otherwise ceases to be the President of the United States for any period of time between market creation and September 30, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”.

This summary shows the opening of the venue's official rules. ProbCast has not yet generated an independent plain-English interpretation for this contract — review the full rules before relying on it.

View full official resolution rules

This market will resolve to “Yes” if Donald Trump resigns or is removed as President or otherwise ceases to be the President of the United States for any period of time between market creation and September 30, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. An announcement of Donald Trump's resignation/removal before this market's end date will immediately resolve this market to "Yes", regardless of when the announced resignation/removal goes into effect. Only permanent removal from office will qualify. Temporary removal (e.g. temporary invocation of the 25th Amendment under Section 3 or a Section 4 invocation not sustained by both Houses of Congress) or impeachment without removal will not count. A sustained invocation of the Twenty-Fifth Amendment, Section 4 (i.e., if both Houses of Congress, by two-thirds vote, uphold the Vice President and Cabinet’s determination of presidential inability) will qualify for a "Yes" resolution. The resolution source for this market will be a consensus of credible reporting.
