Market context

Colombia votes on 31 May to choose the first-round presidential winner, and this market pays out on the candidate who finishes with the most valid votes, not necessarily the eventual president. A YES share means the named outcome happens; a NO share means it does not. Because a candidate can lead the first round without clearing 50%, the field is often easier to read than the runoff outcome, but it still depends on turnout, late momentum and whether opposition votes consolidate behind one contender.

The current 0% YES price implies the market sees that specific named candidate as having almost no chance of topping the first round, which is a stronger view than simply expecting a close race. Colombia’s recent elections show how quickly first-round dynamics can shift: in 2022, Gustavo Petro won the presidency after leading a fragmented field and then facing Rodolfo Hernández in the runoff, while first-round polling often overstated one bloc before late tactical voting set in. For 2026, analysts have highlighted a split between left, centre and right, with Iván Cepeda widely discussed as the frontrunner and conservatives Abelardo de la Espriella and Vicky Dávila among the main challengers, but the first-round leader still depends on whether any bloc unifies in the final stretch.

Watch for final polling releases, coalition signals and any late endorsements or withdrawals, because these can affect who consolidates into the top slot before polling day. Reporting from the Americas Society/Council of the Americas and Americas Quarterly in recent days has pointed to a possible left-versus-right runoff dynamic, but the first-round winner market resolves purely on who receives the most valid votes on 31 May. If official results are delayed, the contract stays open until they are known, and if they are still unresolved by 31 December 2026, it settles to Other.

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.

FAQ

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

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.

What does it cost to trade on PolyGram?
