Market context
Polymarket is pricing this Shuai Zhang v Diane Parry contract at 0% YES, so the current on-chain price on Polygon implies no market support for a Zhang advancement outcome in USDC-settled conditional tokens. For users, that means the contract is effectively trading as if the listed match result is already off the board, even though the settlement still depends on who advances in Strasbourg before the 7-day deadline.
That sort of zero bid is usually read against match context rather than pure win probability. Zhang had already upset Parry in Strasbourg according to WTA’s match report, with the Chinese player moving into her first clay quarter-final since 2021, which explains why traders could be anchoring to a completed-result narrative rather than the original pre-match setup. In comparable tennis markets, sharp repricing to 0% often follows a result being posted, a void condition becoming likely, or the event no longer being live in the market’s settlement sense.
The main things to watch are the official draw and match-status feeds, plus whether the contract has been reconciled from the underlying WTA result. Sofascore listed the match for 20 May at 08:30 UTC, while WTA’s Strasbourg coverage has already reported Zhang as the winner, so a trader would want confirmation of how Polymarket’s oracle and conditional token logic are handling that outcome. If the match is recorded as completed, the market should settle to Zhang; if it is treated as unplayed, abandoned, or otherwise outside the event window, the 50-50 fallback becomes relevant.
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
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
FAQ
- 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.
- What does it cost to trade on PolyGram?
- Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.
- 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.
