Will any presidential candidate win outright in the first round of the Colombia's election?

Platform comparison

Market context

Colombia will hold its presidential election on 31 May 2026, with a constitutionally mandated second round scheduled for 21 June if no candidate secures an outright majority (over 50%) of valid votes cast in the first ballot. The 1% crowd probability reflects the structural difficulty of achieving such a threshold in a fragmented electoral field. Colombian presidential contests have historically required runoffs: in 2022, Gustavo Petro won the second round with 50.4% after finishing first in round one with 40.3%, whilst in 2018 Iván Duque advanced to a runoff despite leading the first round. The electoral landscape typically features multiple viable candidates spanning left, centre and right positions, making consensus-building across a single ballot exceptionally rare under the current constitutional framework established in 1991.

Key developments to monitor include candidate registration deadlines, polling aggregates tracking whether any frontrunner approaches 50% support, and any constitutional amendments that might alter the electoral rules before May 2026. The Colombian electoral authority (Registraduría Nacional) will publish official first-round results within days of voting. Recent reporting from Colombian media outlets indicates the field remains competitive across multiple ideological blocs, with no single candidate demonstrating commanding lead sufficient to suggest first-round victory. Traders should note that the settlement window closes 31 May 2026 at 14:00 UTC, requiring results confirmation by 31 December 2026 to avoid automatic "No" resolution.
