Independiente Medellín vs. CR Vasco da Gama

Platform comparison

Market context

Independiente Medellín hosted Vasco da Gama in the first leg of their Copa Sudamericana last-16 play-off at the Atanasio Girardot, with kick-off set for 22 July at 17:00 local time in Colombia. The market’s 0% YES price sits well below the sort of pre-match probabilities commonly assigned by football models and bookmakers, so it reads more like a stale or lagging contract than a normal pre-game number.[1][2][3]

Comparable pricing for the fixture was not especially one-sided: Sports Mole’s model made Medellín the likeliest winner at 46.31%, with a draw at 27.89% and Vasco at 25.81%, which is much closer to a home-favourite lean than to a near-impossible YES outcome.[3] That divergence matters because the two clubs had no prior official meeting, so the most useful reference point was recent form and home advantage rather than head-to-head history.[1] In a market like this, a zero per cent crowd price usually indicates either very thin participation or a contract that has not yet caught up with match-specific information.

Traders should watch team news, venue and travel timing, and any late competition updates, because South American knockout ties can move quickly on line-ups and availability. ESPN Deportes and TyC Sports both confirmed the scheduled start and the Atanasio Girardot venue, while TyC noted the usual regional broadcast pattern for CONMEBOL matches, which often tracks the availability of live market information around kickoff.[1][2] If lineups, rotation, or a suspension update were to favour one side, that would be the most plausible catalyst for a meaningful repricing before the settlement window closes on 22 July 2026 at 22:00 UTC.

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
