Market context

Colombia will hold its presidential election on 31 May 2026, with a potential runoff scheduled for 21 June if no candidate achieves an outright majority in the first round. This market resolves on whoever receives the most valid votes in the initial ballot, regardless of whether they cross the 50% threshold required to avoid a second round. The 0% implied probability on YES suggests the crowd expects a fragmented field where no single candidate dominates the first-round vote share—a reasonable baseline given Colombia's recent electoral history and the typical distribution of support across multiple viable candidates.

Colombian presidential contests have consistently produced first-round winners with pluralities rather than majorities. In 2022, Gustavo Petro won the runoff but finished second in the first round with roughly 40% of votes; in 2018, Iván Duque took the first round with 39%. The pattern reflects a competitive multiparty system where leftist, centrist, and conservative blocs fragment the electorate. Historical precedent suggests markets should calibrate expectations around whether any single candidate can consolidate enough support to lead outright—a threshold that has proven difficult to achieve in recent cycles.

Key variables for traders include candidate registration deadlines, campaign momentum shifts, and polling releases through early 2026. Economic conditions—inflation, unemployment, and security concerns—will shape voter preferences heading into the election. The Colombian electoral authority (CNE) typically releases preliminary results within hours of polls closing, minimising settlement delays. Any significant polling divergence or late-stage candidate withdrawals could alter the distribution of first-round support, particularly if consolidation occurs around a frontrunner in the weeks before voting.

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

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.

FAQ

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 Best Prediction Markets?

Zero. Best Prediction Markets routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, Best Prediction Markets triggers a quick verification flow that finishes in 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.
