Colombia Presidential Election

Market context

Colombia will hold a presidential election on 31 May 2026, with a potential runoff on 21 June if no candidate achieves an outright majority. The current administration under Gustavo Petro, who won in 2022 with a centre-left platform, will not be eligible to stand for re-election due to constitutional term limits. This creates an open field where multiple candidates from across the political spectrum are expected to compete, making outcome prediction substantially more uncertain than races involving an incumbent.

Historical precedent suggests Colombian runoffs occur frequently: the 2022 election required a second round, as did 2018 and 2014. When no candidate clears 50% in the first ballot, the top two finishers advance, fundamentally reshaping coalition dynamics and voter behaviour. The 2022 runoff saw Petro gain 8 percentage points between rounds, demonstrating that first-round polling provides incomplete information for final outcomes. Traders should treat the May ballot as a data point rather than a settlement event; programmatic strategies relying solely on first-round results will misfire.

Key catalysts include candidate registration deadlines (typically 60 days before the election), major campaign announcements, and economic data releases that may shift voter sentiment. The Colombian peso's performance and inflation figures—currently elevated—will likely influence messaging around fiscal policy. Monitoring Colombian news sources including Caracol Radio and El Tiempo for polling releases and campaign developments is essential. The 21 June settlement window provides a hard deadline; any ambiguity in official results after that date triggers resolution to "Other," creating tail risk for positions held through the runoff period.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
