Market context

Colombia will hold its first-round presidential election on 31 May 2026, with results determining whether a runoff becomes necessary. The 0% probability assigned to a first-round winner reflects the Colombian electoral system's structural bias towards second rounds: since 1991, only one candidate has secured over 50% of valid votes in a first round (Álvaro Uribe in 2002 with 53.1%). The fragmentation of Colombia's political landscape—spanning centre-left, centre-right, and regional movements—typically produces plurality rather than majority outcomes, making outright first-round victories exceptionally rare.

Historical precedent suggests traders should expect a runoff. Colombia's 2018 and 2022 elections both required second rounds, with first-round winners receiving 37.8% and 40.1% respectively. The current political environment shows no consolidation patterns that would reverse this trend. Candidates must navigate competing constituencies across economic policy, peace agreement implementation, and security priorities without commanding sufficient consensus for a majority.

The resolution window extends to 31 December 2026, providing substantial time for official certification. Key dates include campaign registration deadlines and the electoral authority's formal announcement of results, typically within days of voting. Any administrative delays or legal challenges to results could affect resolution timing, though Colombia's electoral commission has maintained reliable certification processes in recent cycles. Traders should monitor polling aggregates through May for any unexpected consolidation around a single candidate, though historical patterns make such movement unlikely to reach the 50% threshold required for first-round settlement.

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.
