Market context
Polymarket is effectively pricing this USDC contract on Polygon as a near-certainty, with the market sitting at **100% YES** for Facundo Acosta advancing over Vilius Gaubas. In practical terms, that means the conditional token stack is already valued as if the Acosta side will resolve positively, so the main risk is not a simple upset but a settlement wrinkle: if the match is not played, is abandoned without a winner, or slips beyond the seven-day window, the market can still resolve to 50-50 under the contract terms.
That pricing fits the tennis context. Acosta is the higher-ranked player at ATP No. 107 versus Gaubas at No. 128, and San Marino reports have framed Acosta as the top seed who arrived after a strong clay run this season, while Gaubas reached the semi-final by edging Thiago Monteiro in two tie-break sets.[3][6][10] The pair have also already met once this year, with Acosta winning their Braunschweig match 2-0, which helps explain why the market has not left meaningful odds for the Lithuanian side.[4][14]
For traders, the key catalysts are confirmation that the semi-final starts as scheduled on Centre Court and that it is actually completed within the settlement window. Live schedule feeds currently place the match at 17:10 UTC, but the market description fixes the original slot at 2:30 PM ET, so any delay, suspension, or rescheduling matters less than whether a winner is eventually recorded.[2][9] San Marino Open organisers and broadcasters have also stressed full coverage of the event, which should make any late-court changes or retirements visible quickly rather than ambiguous.[16]
Methodology
This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.
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.
