This market will resolve to Yes if the US Congress overrides a presidential veto by December 31, 2026 at 11:59PM ET. Otherwise this market will resolve to "No". Passage of a veto override by only one Chamber of Congress shall be insufficient to cause this market to resolve to "Yes". The resolution source will be official U.S. federal government publications (e.g., Congress.gov) however a consensus of credible reporting may also be used.
