Colombia Presidential Election

Market context

Colombia votes in the first round of its presidential election on 31 May, with a run-off due on 21 June if no candidate clears 50 per cent of valid votes. The latest cited Invamer polling has Iván Cepeda, the left’s candidate from Gustavo Petro’s Historic Pact, in front on 31.9 per cent, ahead of Abelardo de la Espriella on 18.2 per cent and Sergio Fajardo on 8.5 per cent, which helps explain why outright first-round win markets remain cautious even when the frontrunner leads. In a second-round projection, Cepeda is still favoured in some match-ups, but only narrowly against Fajardo, while his margin widens against de la Espriella, reinforcing that the market is really pricing a two-stage contest rather than a simple single-ballot outcome.

For comparison across venues, Polymarket quotes a live yes/no probability, while Kalshi resolves against the certified winner and typically trades in implied-probability terms rather than decimal odds; Betfair and Smarkets, where available, usually show back/lay prices in decimal format, with commission and market depth affecting the effective price. The practical difference on this market is that exchange-style books can diverge from headline polling because traders must also price turnout, coalition transfers and the run-off sequence. Recent reporting from AS/COA and Justice for Colombia points to Cepeda, de la Espriella and Paloma Valencia as the key names to watch, with the main uncertainty being whether the first round produces a near-run-off finish or a decisive winner.

Methodology

This page compares Colombia Presidential Election specifically across Polymarket, Kalshi, Betfair Exchange and Smarkets. Live odds come from the Polymarket order book; the other venues' contract details are maintained manually because their APIs aren't directly comparable. Every CTA routes to PolyGram, which mirrors the Polymarket order book at 0% fees.

Resolution & payout

Settlement is the biggest difference between the four platforms: Polymarket on-chain in USDC (instant), Kalshi USD via CFTC (T+1), Betfair and Smarkets in local currency via bank withdrawal (T+1 to T+3). PolyGram routes every trade directly into Polymarket's on-chain settlement, which is why payouts land fastest.

FAQ

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.
