Market context

Colombia is choosing its next president in a runoff between Abelardo de la Espriella and Iván Cepeda, with the second round scheduled for 21 June 2026 and preliminary results expected soon after polls close. Reuters reported that de la Espriella entered the vote with a lead in current polling, while the first round finished with him on 43.7% and Cepeda on 40.9%, so the market is really about how wide the final valid-vote gap turns out to be rather than who merely finishes first.[1][2]

For a 1% “yes” price, historical context matters because Colombian runoffs can tighten or widen materially once eliminated candidates’ supporters reallocate, turnout shifts, and regional counts come in. The first round also matters as a baseline: a mid-single-digit spread there implies that a close runoff is plausible, but a decisive margin is not impossible if one camp consolidates better. In a programmatic workflow, that means treating polling, first-round vote shares, and late turnout signals as live inputs, then updating any conditional order logic once official count data starts moving.[2][4]

The main catalysts are the vote itself, turnout, and the official results timetable. Reuters said more than 41 million Colombians are eligible and voting runs from 8 a.m. local time for eight hours, with preliminary results due shortly after polls close, so market moves should cluster around exit-count cadence and the first official tallies.[1] Security and conflict headlines have also featured heavily in coverage, which can affect participation and the perceived strength of each candidate’s coalition in the final margin calculation.[5][7]

Methodology

We track Colombia Presidential Election Runoff: Margin of Victory on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.
