Abelardo de la Espriella and Iván Cepeda Castro advanced to Colombia’s June 21 presidential runoff after finishing first and second in the May 31 first round with 43.7 percent and 40.9 percent of the vote, respectively. Official tallies showed neither candidate reached the 50 percent threshold required for an outright victory, concentrating more than 84 percent of valid ballots between the right-wing outsider and the left-wing Historic Pact senator. This outcome aligned with voter turnout exceeding 57 percent and consolidated support along ideological lines on security and economic policy. Trader consensus at 100 percent for their advancement reflects the confirmed preliminary and final results, while the negligible probability assigned to an outright first-round winner tracks the narrow margin between the top two. Late recounts, formal challenges, or procedural disputes remain the only narrow pathways that could alter the field before runoff ballots are cast.
