Independiente Medellín vs. CR Vasco da Gama

Platform comparison

Market context

Independiente Medellín vs CR Vasco da Gama in the Copa Sudamericana is priced at **0% YES** on Polymarket right now, so the contract is effectively saying the event has no remaining chance in the market’s view. For a Polymarket user, that means the conditional tokens tied to a YES outcome are trading as if the settlement has already been locked out, with USDC on Polygon reflecting that the crowd sees no viable path to a positive resolution before the window closes.

That reading is easier to place against the pre-match consensus, which was not heavily one-sided. Polymarket’s own event page described Medellín as having a slight edge on home advantage, while a separate model from Sports Mole put Independiente Medellín at 46.31% to win, ahead of Vasco at 25.81% and the draw at 27.89%.[7][4] Comparable knockout first legs in South American competition often stay close because home strength, travel, and game state matter more than raw team reputation, and a single late goal can shift settlement outcomes sharply.[2][4]

The main catalysts a trader would have watched were the official team sheets, any postponement or venue change, and confirmation from CONMEBOL that the fixture went ahead at Estadio Atanasio Girardot with the listed referee, Piero Maza Gomez.[2] Broadcast listings from beIN SPORTS and TyC Sports confirmed the match was scheduled for Wednesday, 22 July at 19:00 local time, which is the sort of timing detail that can matter for final settlement when a market is still live.[1][6] With the market already at 0% YES, any remaining relevance would come from whether the contract’s settlement rules hinge on the official result record rather than live scorelines alone.[2]

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.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Kalshi UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

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.
