Market context
Atalanta BC vs Athletic Bilbao is a completed club friendly at Bergamo, and Polymarket is marking the “More Markets” contract at 0% YES, which means the market is pricing no remaining settlement path rather than debating the football itself. On Polymarket, these contracts sit on-chain with USDC collateral, Polygon settlement and conditional tokens, so once the official result feed resolves the event, the market snaps to the final outcome rather than drifting on late opinion.
The 0% reading is easiest to understand against comparable friendly markets: once a match is underway or final and the resolution criteria are clear, traders usually remove any residual premium quickly, especially in low-liquidity side markets. In practice, the contract is no longer about forecasting Atalanta or Athletic Bilbao; it is about whether the result, timing and market definition have all been locked in cleanly before the settlement window closes.
A trader would still watch for delayed official reporting, abandoned-match flags, or corrections to the fixture record, because those are the only realistic dependencies left in a settled club-friendly market. The published kick-off was 18:45 UTC on 14 August, and live-score services already show a completed 1-0 result, so the main catalyst is confirmation that the market’s resolution source matches the final scoreline and no administrative change is filed before the window ends.
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
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.
UK Frequently Asked Questions
