Market context
Polymarket has this contract at 0% YES, so the board is implying no listed exact score is currently trading above the floor while the event is still unresolved. For a domestic league match at Estádio Beira-Rio, that usually means the market is pricing either a low-liquidity misread or a late-reported fixture state rather than a genuine expectation of a specific scoreline; on Polymarket’s USDC/Polygon setup, the conditional token only settles once the match result is confirmed from regulation plus stoppage time.
The closest comparable framing is a tight Brazilian Série A meeting rather than a goal-fest: recent pre-match models and listings have pointed to Internazionale as the likelier side, with low-margin outcomes and exact scores such as 1-0, 1-1 or 2-0 carrying most of the action. Head-to-head data are thin, which matters in exact-score markets because one prior meeting is not enough to build much signal, and the “Any Other Score” bucket remains live whenever the final line falls outside the listed set.
A trader still watching this contract should focus on whether the fixture is locked in, delayed, or void-risked, because the settlement window ends at 2026-08-17T23:00:00Z and a postponement would keep it open until completion. Team news, referee assignment and any schedule change from league or club channels are the practical catalysts; the match listings show a 23:00 UTC kick-off on 17 August, but several feeds disagree on venue naming and timing, so confirming the final match state is the key dependency before settlement.
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.
