Market context

Colombia will hold its presidential election on 31 May 2026, with voters selecting their next leader for a four-year term. The first-round winner is determined by plurality—whoever receives the most valid votes advances, regardless of whether they exceed 50%. A second round runoff occurs on 21 June only if no candidate clears that threshold in the initial ballot.

The 0% implied probability reflects the market's confidence that a runoff will occur. Historically, Colombian presidential elections have frequently required second rounds. In 2022, Gustavo Petro won the first round with 40.3% of votes but needed the runoff to secure victory. The 2018 election similarly went to a second round, as did 2014 and 2010. This pattern suggests structural fragmentation in the Colombian electorate—multiple viable candidates typically split the vote sufficiently to prevent a first-round majority. Current polling indicates the 2026 field remains competitive across several candidates, with no single frontrunner commanding 50%-plus support in early surveys.

The settlement window closes 31 May 2026 at 16:00 ET, giving Colombian authorities time to report official results from the Registraduría Nacional del Estado Civil. Key catalysts include candidate registration deadlines (typically January–February 2026), campaign event schedules, and any shifts in coalition-building that might consolidate support behind particular candidates. Economic conditions—inflation, unemployment, and security concerns—will shape voter preferences throughout the campaign period. Traders should monitor whether any candidate emerges with sufficient polling strength to threaten a first-round victory, as this remains the contrarian angle against the current consensus.
