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

Platform comparison

Market context

Colombia's 31 May 2026 presidential election will require a runoff unless a single candidate secures over 50% of valid votes in the first round—an outcome the market currently prices at just 1%. The electoral system has consistently produced two-round contests in recent decades, with no candidate achieving an outright majority since the current constitutional framework took effect in 1991.

Historical precedent strongly supports the low probability. Colombia's last five presidential elections (2010, 2014, 2018, 2022) all proceeded to second rounds, with first-round winners garnering between 27% and 41% of the vote. The fragmentation of the Colombian political landscape across left, centre, and right blocs, combined with mandatory voting and a diverse electorate spanning urban and rural regions, has structurally prevented first-round victories. Even candidates with substantial polling leads have fallen short of the 50% threshold.

Traders should monitor candidate registration deadlines and coalition announcements through early 2026, as unexpected consolidation around a single frontrunner could theoretically shift dynamics. Current polling data from firms like Invamer and CNC will provide the most reliable signals as the election approaches. The settlement window closes 31 May 2026 at 14:00 UTC, aligned with official results from Colombia's National Electoral Council (CNE). Any ambiguity regarding vote tallies would trigger resolution to "No" by the December 2026 backstop date.

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
