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

Platform comparison

Market context

Colombia will hold its presidential election on 31 May 2026, with a constitutionally mandated second round scheduled for 21 June if no candidate achieves an outright majority (>50%) of valid votes cast. The 1% implied probability reflects the structural difficulty of clearing this threshold in a fragmented electoral landscape. First-round victories in Colombian presidential contests are exceptionally rare; the country has required runoff elections in most recent cycles, including 2022 (Gustavo Petro vs Rodolfo Hernández), 2018 (Iván Duque vs Gustavo Petro), and 2014 (Juan Manuel Santos vs Óscar Iván Zuluaga). Historical precedent suggests that unless a single candidate commands overwhelming organisational reach and polling dominance months before the election, vote splitting across multiple viable contenders will fragment the first-round result below the 50% threshold.

Traders monitoring this market should track candidate registration deadlines (typically 90 days before the election) and early polling aggregates from Colombian firms such as Invamer and Datexco. Coalition-building announcements will signal whether major parties are consolidating behind single candidates or fielding parallel slates. The Electoral Observation Mission (MOE) and the National Electoral Council (CNE) publish official results within days of voting; any ambiguity around vote counts or validity challenges would trigger the December 2026 resolution backstop. Programmatically, this market functions as a high-confidence NO position unless polling data shows a single candidate consistently polling above 55% with less than three months remaining—a scenario not currently reflected in pre-campaign positioning.

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.
