Market context

Colombia votes in its presidential election on 31 May, with a possible runoff on 21 June if no candidate clears 50% in round one. The market’s 0% YES price implies a near-blank slate, but the public record points to a clear front-runner rather than a true open field: Iván Cepeda has led most recent polling, while Abelardo de la Espriella and Paloma Valencia have been the main conservative alternatives. That makes the consensus read as Cepeda-favoured, with the value question less about whether the left can lead the first round than whether the opposition can consolidate quickly enough for a second-round upset.

The historical and polling frame matters because Colombia has repeatedly produced runoffs when the first-round leader falls short of an outright majority, and current surveys suggest that is the base case again. Americas Quarterly reported that Cepeda leads in every major poll, but is still well below the 50% threshold needed to avoid a second round, while a projected head-to-head can tighten materially depending on which conservative reaches the runoff. Recent Invamer polling cited by Justice for Colombia put Cepeda on 31.9%, ahead of de la Espriella on 18.2% and Sergio Fajardo on 8.5%, underlining that the favourite is ahead, but not yet in clinching distance.

For traders, the main catalysts are the last wave of polling, campaign alliances after the first round, and turnout among anti-Petro voters. The decisive dependency is whether de la Espriella, Valencia or Fajardo can unify the centre-right vote if Cepeda finishes first without a majority. The runoff pair matters as much as the first-round order: reporting this month suggests Cepeda is strongest against de la Espriella, but could face a narrower race against a more broadly acceptable centrist. In other words, the consensus leans toward a Cepeda win, but the most obvious contrarian angle is a second-round coalition against him if the opposition avoids fragmentation.

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.
