Market context
Xiyu Wang and Mayar Sherif are due to meet in the Brescia final on clay, with the market already priced at 0% YES despite live listings still showing the contest as pending or completed depending on feed latency.[1][2][3] That gap matters because the market only resolves to a player if that player advances; if the match was not played, or was abandoned without a winner, the fallback is 50-50 under the rules.
The current price is easier to read through recent comparable cases than through the crowd number alone. The pre-match market and independent tennis feeds both leaned Wang, with Tennis.com projecting her at 64% and flashscore listing her as the 1.49 favourite against Sherif’s 2.55, yet Sherif’s head-to-head edge has been noted by TennisStats, which says she has won more of their meetings.[1][2][4] That combination usually produces a relatively tight final rather than a one-sided spot, especially on clay where Sherif’s heavy topspin game is often more effective than on faster surfaces.
The main catalysts are straightforward: official match confirmation, whether the final starts on schedule, and whether either player withdraws or retires before completion. FanDuel listed the match for 11:30am ET, while other live feeds showed a 15:30 UTC slot, so traders should watch for last-minute schedule shifts or scoring-feed discrepancies that could affect settlement timing.[3][7][8] Recent result feeds also indicate the match has been tracked to completion by some providers, making any late cancellation, walkover, or retirement the key dependency for the 50-50 fallback rather than the outright winner.
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.
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.
FAQ

- Is this market available outside the US?
- Sport Prediction is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.
- What's the difference between YES and NO shares?
- A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

- The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
