Market context
Polymarket is pricing this Copa Sudamericana tie as a **0% YES** contract for the “More Markets” slate, so the market is effectively saying there is no active path to a positive settlement at the current price. On Polymarket, traders fund positions in **USDC** on **Polygon**, and the contract settles through **conditional tokens** tied to the match-specific outcome set rather than the underlying football result in isolation.[2][7]
That near-zero price reads as a strong signal that the market has either already resolved in practice or that traders see no remaining uncertainty inside the settlement window. By comparison, conventional pre-match pricing treated Independiente Medellín v Vasco da Gama as a fairly balanced knockout contest, with one bookmaker listing home win, draw and away win around 2.28, 3.25 and 3.15 respectively, and several previews leaning towards goals or both teams to score.[1][3][5][6] For Polymarket users, that kind of comparative framing matters because “More Markets” contracts can move differently from the headline match winner if the settlement definition depends on a specific stat, card, or timing condition.
The main catalysts to watch are official match reports, league or CONMEBOL updates, and any correction to line-ups, venue, or kick-off records, because those are the usual sources that determine whether a conditional token settles one way or another.[1][10] The fixture was scheduled for 22 July at Estadio Atanasio Girardot in Medellín, and even small administrative changes can matter more than the betting consensus when a contract is linked to a narrow market definition rather than the final scoreline.[1][2]
Methodology
This page reviews Independiente Medellín vs. CR Vasco da Gama - More Markets across five venues. The live probability is the Polymarket mid-price, sourced directly from the on-chain Polygon order book; the comparison columns benchmark each venue on fee structure, KYC, settlement currency and payment rails. Every CTA routes to PolyGram, which mirrors the Polymarket order book at 0% fees.
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
- 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 Polymarket cost to trade?
- Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.
- Do I need to KYC for this market?
- On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram 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.
