Market context
Polymarket is pricing this Coco Gauff v Elina Svitolina contract at 0% YES, which implies the market is currently treating a Gauff advance as effectively impossible despite the final being scheduled for later today. On Polymarket, the outcome is settled in USDC on Polygon through conditional tokens, so the relevant question is not the match winner in the abstract but whether the contract resolves to Gauff, Svitolina, or falls back to the 50-50 clause if the match is not played, is tied, or is delayed beyond the settlement window. Svitolina has the stronger recent head-to-head context, with reports of a 3-2 edge and a straight-up win in their Dubai semi-final this year, while Gauff also has Rome pedigree as the defending finalist.
The main historical read-through is that Rome clay has not produced a simple ranking-based outcome here: Svitolina has won the tournament twice before, in 2017 and 2018, and she reached this final by beating Iga Swiatek in three sets, a result that supports the case that she is fully live on this surface. Gauff, by contrast, is back in the Rome final after losing last year to Jasmine Paolini, which shows she has the clay game to reach this stage again but not necessarily the cleanest path to outright control. That combination helps explain why a 0% quote is unusual: if the market is functioning normally, even a small chance of Gauff advancing should generally leave some non-zero price.
Traders should watch for the confirmed court time and any late schedule changes, because the market description allows a 50-50 resolution if the match is not completed and no winner emerges within seven days. Sky Sport and other Italian outlets reported the final for 17:00 local time on Campo Centrale, with live coverage also expected on SuperTennis, but finals can slip if earlier matches run long or weather intervenes. Any official ATP/WTA or tournament announcement on start time, suspension, or completion matters more than form narratives, because the on-chain outcome depends on whether the match is actually played to a decisive advance before the settlement deadline.
Methodology
This page is a comparison snapshot: one live quote (Polymarket), 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.
