Market context
Polymarket is pricing this contract at **0% YES** today, which means the market is treating the “more markets” outcome on the 4 August Colombia Primera A meeting between CD Tolima and Independiente Medellín as effectively unavailable on the current information set. On Polymarket, the trade is settled in **USDC** on **Polygon** through conditional tokens, so the key question for users is not the abstract football fixture alone, but whether the specific named market condition was met before the settlement window closed at 23:15 UTC on 4 August.
The historical framing is straightforward: Tolima and Medellín have usually been a tight, low-scoring pairing rather than a one-sided fixture. Across long-run head-to-head samples, the teams are close on wins and draws are common, while recent aggregate data also points to modest goal totals and a tendency for both sides to stay in games rather than blow them open.[3][7][18] That matters for reading a yes-or-no ancillary market, because these contracts often move on narrow procedural details, not just the final scoreline.
For traders, the main catalysts are confirmation of the match sheet, any official club or league updates, and whether the market description maps cleanly onto a final, in-play, or post-match submarket before the settlement cut-off. ESPN and live-score services list the fixture for 4 August, which helps anchor timing, but the decisive inputs are still the event record and any dependency on added markets being published in time.[8][1][2] If the underlying match was delayed, altered, or if the relevant market type never appeared on-chain in the expected form, that would be the practical driver of settlement rather than team form alone.
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.
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.
