Once Caldas vs. América de Cali - More Markets

Platform comparison

Market context

Once Caldas meet América de Cali in Colombia Primera A, a fixture that has been stubbornly tight and often low-scoring. Across recent head-to-head data, the sides have split results evenly overall, with a large share of draws; one summary shows 37 meetings since 2005 producing 17 stalemates, while more recent form includes 1-1 results in January 2026 and several 0-0 or 1-1 meetings in late 2023–2024[1][3][8][17][20]. For a “More Markets” contract, that sort of match history matters because programmatic traders often weight correlated sub-markets — for example, cards, corners, both teams to score, or exact score bands — more than the outright result when the base fixture profile is cagey.

The current 0% YES crowd price suggests the market is either effectively dead or still missing the specific “more markets” trigger being monitored, so it should be read as a tooling problem as much as a football signal. In practice, a bot or conditional-order workflow would watch the match page, market-creation status, and settlement timestamp together, then only fire if the exchange publishes an eligible supplementary market before the window closes at 2026-08-06T01:30:00Z. The main catalysts are simple but time-sensitive: official team news, any fixture delay, and whether the operator exposes additional prop lines for the August 5 9:30 PM ET kick-off; once those inputs are fixed, the probability can jump from operational zero to a tradable state very quickly.

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.
