Once Caldas vs. América de Cali

Platform comparison

Market context

Once Caldas face América de Cali in Colombia Primera A, and the market’s **0% YES** price is an outlier against the game’s long-run balance. The head-to-head is draw-heavy: multiple databases show 17 draws in 37 meetings, with each side winning 10 times overall, while more recent records are still tight, including 1-1 draws in January 2026 and a 3-0 Once Caldas win in April 2025[1][3][5][12]. That history matters because it points to a low-scoring, high-variance fixture rather than a one-sided matchup, so a zero-implied probability generally looks much harsher than the underlying football would suggest[1][5][16].

For traders, the main catalysts are line-up information, late injury or suspension news, and any schedule or rotation angle created by the wider Primera A calendar; there is no fresh team-specific injury bulletin in the sources here, so the most useful cross-check is whether sportsbook prices move before kick-off while the market stays pinned at zero. In comparable meetings, prices have often tracked the derby-like draw profile rather than a dominant favourite, so a meaningful divergence would be a sportsbook market showing a modest chance for either side or the draw while the prediction market still implies none at all[2][8][15][19]. If pre-match team news confirms unchanged first XIs, the historical evidence supports a relatively conservative read on any explosive move away from a low-event outcome.

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.

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 fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

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.
