Market context

Coco Gauff and Elina Svitolina are due to meet in the Rome final after both won through on clay. Svitolina beat Iga Swiatek 6-4, 2-6, 6-2 in the semi-finals, while Gauff defeated Sorana Cîrstea in straight sets. The 0% YES price is consistent with a market that has not yet reflected the confirmed final, but settlement is straightforward: if Gauff advances she resolves as YES, if Svitolina advances she resolves as NO, and if the match is not completed within the contract’s window the market falls back to 50-50.

The historical frame leans slightly towards Svitolina. She leads the head-to-head 3-2 and won the two most recent meetings, both on hard courts in Dubai and at the Australian Open. However, this will be their first clay-court meeting, which matters in Rome because longer rallies and lower bounce tend to reward patience and court position more than first-strike power. Svitolina is also playing in a familiar setting: she has twice won in Rome and is back in a title match eight years after her last appearance. Gauff is the higher-ranked player and has reached the final for the second straight year, but she has not had the same historical edge in this matchup.

Traders should watch for final scheduling, any late fitness news, and whether the match starts on time, because the contract only resolves on an actual winner within seven days of the original date. The relevant on-chain mechanic is simple: USDC settlement depends entirely on the official result, with no price discovery from in-play score effects once the market is closed. More broadly, when a market is priced at zero despite a confirmed fixture, it often reflects stale order books rather than a true null probability, so the key catalyst is the final’s confirmation and completion rather than any broader crypto move.

Methodology

Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — are listed with their platform attributes, because they operate off-chain and a 1:1 comparison of contract mechanics isn't possible.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

FAQ

Where can I trade this market with the lowest fees?

On PolyGram, which mirrors the Polymarket order book at 0% fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

Is this market available outside the US?

PolyGram 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.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

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.

How reliable are the quoted odds?

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.
