Market context
Once Caldas meet América de Cali in Colombia Primera A, and Polymarket is pricing the **“More Markets”** contract at **0% YES** today, which means the market is treating a positive settlement as effectively unavailable on current information. On Polymarket, this is an on-chain position settled in **USDC** on **Polygon** through conditional tokens, so the price reflects how traders value the contract’s exact resolution, not the match in the abstract.
Historical head-to-head data suggests this pairing can be tight rather than one-sided. Across reported league and cup samples, the clubs have split wins broadly evenly over the long run, while recent meetings have leaned towards low margins and draws, including a **1-1** in January 2026 and a run of recent results that included **Once Caldas 3-0 América de Cali** in April 2025 and **América de Cali 2-1 Once Caldas** in September 2025.[3][8][10] Longer-run records also show a substantial draw rate in the fixture, which is relevant for any “more markets” contract whose settlement depends on a specific match outcome or side market rather than the headline result alone.[1][6]
The main catalysts for traders are the confirmed match schedule, line-ups, and any late administrative changes that could affect the settlement condition before the window closes at **2026-08-06T01:30:00Z**. Because the contract is tied to a fixed fixture time, users should watch for official competition updates, kick-off changes, postponed play, or market-definition issues on Polymarket’s event page; recent previews and fixture listings still place the game for early August 2026.[8][13][16] In practice, once the match goes ahead, the most important dependency is whether the exact “more markets” condition is satisfied under Polymarket’s rules, since the token settles only if the encoded outcome matches the event definition.

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.

FAQ
- 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.
- 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.
- 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.
