Santos FC vs. CSyD Macará

Platform comparison

Market context

Santos FC’s Copa Sudamericana tie with CSyD Macará was scheduled for Estádio Urbano Caldeira, with kick-off listed at 22:00 UTC on Thursday 13 August 2026. The market’s 100% YES price is far more extreme than the surrounding pre-match pricing: sportsbook and model pages clustered around Santos as a clear favourite, but still left a meaningful chance of an upset or draw, with home-win odds around 1.33-1.42 and modelled win probabilities nearer the mid-40s to mid-60s rather than certainty.[1][7][10][11]

That gap matters because the historical and comparable-case frame does not support a literal lock. Independent preview sites treated this as a first meeting and a standard last-16, first-leg home-favourite spot, where the home side’s stronger market position was offset by the usual caution of continental knockout football and Macará’s ability to keep matches tight enough to preserve variance.[7][9][11] In other words, the sportsbook consensus pointed to Santos, but not to a probability that cleanly justifies a 100% settlement expectation.[4][10][11]

The main catalysts traders would have watched were lineup and team-news confirmations, venue and broadcast arrangements, and any change to scheduling in the hours before kick-off. GOAL listed beIN SPORTS, beIN SPORTS Connect and Fubo as viewing options, which is useful mainly as a sign the fixture was fully operational on the broadcaster side rather than subject to a known cancellation risk.[2] With the match already listed on multiple live-score and odds pages, the remaining practical swing factors were late injury or rotation news and any pre-match odds move away from the broad Santos favourite consensus.[1][6][8]

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
