Colombia Presidential Election

Market context

Colombia will hold a presidential election on 31 May 2026, with a constitutionally mandated runoff on 21 June if no candidate reaches 50% of valid votes in the first round. The settlement window closes at the second-round date, meaning traders must account for a two-week gap between initial results and final resolution. Current incumbent Gustavo Petro, elected in 2022 as the country's first leftist president, is constitutionally barred from immediate re-election, creating an open field across ideological lines.

Colombian presidential contests have historically produced runoffs: in 2022, Petro secured 40.3% in the first round before winning the second round with 50.4% against Rodolfo Hernández. The 2018 election similarly required a second round. This pattern suggests traders should model scenarios where no candidate dominates the first ballot, requiring conditional logic to track leading candidates and their coalition-building capacity between rounds. Polling volatility in Colombian elections has been substantial—Hernández's 2022 surge from single digits to a runoff finalist illustrates how late momentum and anti-establishment sentiment can reshape outcomes.

Key catalysts include candidate registration deadlines (typically January 2026), campaign financing disclosures, and monthly polling releases from firms including Invamer and CNC. Economic conditions—inflation, unemployment, and coca cultivation trends—influence voter sentiment toward Petro's left-wing policies. Traders implementing automated monitoring should flag announcements from the Registraduría Nacional del Estado Civil (Colombia's electoral authority) regarding candidate eligibility and any procedural changes. The two-week gap between rounds creates arbitrage opportunities for conditional orders tied to first-round results.

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
