CF América vs. San Diego FC - More Markets

Platform comparison

Market context

Club América meet San Diego FC in a Leagues Cup match scheduled for 6 August, and Polymarket currently prices the “More Markets” contract at a **100% YES** crowd-implied probability, which means the market is effectively treating the relevant condition as already certain on-chain. On Polymarket, that view is expressed through USDC-denominated trading on Polygon via conditional tokens, so the price is a live read of how traders expect the contract to settle rather than a simple abstract prediction about the fixture itself.

For context, the wider match markets around this tie have consistently leaned towards Club América, with external preview outlets also framing América as the favourite and San Diego as the upset side. Leagues Cup’s own preview noted América had about 66% of the market versus 16% for San Diego FC, while other prediction sites put América in the mid-60s to low-70s for a straight win, which is useful background because “more markets” contracts typically track whether a game generates enough listed sub-markets or related settlement conditions to leave little room for ambiguity.[6][10][12][13]

A trader watching this contract would focus less on the scoreline and more on operational details: the match start time, whether any market is postponed or reopened, and whether the relevant markets are actually posted and kept open through the settlement window ending 2026-08-07T02:00:00Z. Polymarket’s own market page states that if the game is postponed the market stays open until completion, and if cancelled without a make-up it resolves No, so late schedule changes or Leagues Cup broadcast updates are the main dependency to monitor.[2]

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.
