Colombia Presidential Election Runoff: Margin of Victory

Market context

Colombia’s presidential runoff is deciding whether Abelardo de la Espriella or Iván Cepeda wins the presidency, and the market is about the *size* of that final gap rather than the winner. Official first-round results had de la Espriella on about 43.7% and Cepeda on about 40.9%, so the starting point for the second round is a relatively narrow, high-salience contest that can still produce an unexpectedly large or small winning margin depending on turnout and vote transfers.[2][3][4]

For a power-user running this programmatically, the key historical lens is that Colombian runoffs often compress around coalition behaviour: the first round reveals core support, but the second round margin depends on whether eliminated candidates’ voters abstain or consolidate. A market priced at 1% YES implies the crowd sees a very specific margin band as unlikely, so it is worth mapping thresholds directly against expected runoff mechanics rather than treating this as a generic winner market; small shifts in turnout, regional participation, or late endorsement flows can matter more than headline polling once the field is reduced to two names.[2][5]

The immediate catalysts are operational rather than speculative: polling took place on Sunday, preliminary results were expected shortly after the polls closed, and over 41 million people were eligible to vote, with voting scheduled from 8 a.m. local time for eight hours.[1] Traders watching for automated triggers should key off the official count stream, any delays in reporting from the electoral authority, and final turnout data, because a margin-of-victory settlement depends on valid-vote percentages for the top two candidates, not raw vote totals.[1]

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket Bot UK, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
