Market context
Tereza Valentova and Magda Linette are scheduled to contest a first-round match at Roland Garros on 24 May 2026. The 0% implied probability reflects either minimal trading volume or a technical issue with market initialisation, as both players have established WTA tour records and the match carries standard clay-court variables. Settlement occurs within seven days of the scheduled date; any cancellation, tie, or unresolved outcome beyond that window triggers a 50-50 resolution.
Linette, a Polish player ranked in the WTA top 100 for most of 2024–2025, brings consistent Grand Slam qualification and prior Roland Garros main-draw experience. Valentova, a Czech player, has competed in WTA qualifying rounds but lacks comparable main-draw history at majors. Historical precedent suggests markets pricing a lower-ranked or less-experienced player at zero probability often reflect data gaps rather than genuine certainty; programmatic traders typically flag such extremes as either liquidity voids or settlement-rule edge cases rather than genuine prediction signals.
Monitoring points for conditional order logic include official Roland Garros draw confirmation (typically released 2–3 weeks pre-tournament), injury bulletins from both camps, and court assignment announcements. Clay-court form in the weeks preceding Roland Garros—particularly results from WTA 1000 events in Madrid and Rome—will inform late-stage position adjustments. The 5:00 AM ET slot suggests an outer-court assignment; weather delays on clay are common, making the seven-day resolution window operationally relevant for automated settlement checks.
Methodology
This page reviews Roland Garros WTA: Tereza Valentova vs Magda Linette across five venues. We show live odds for Polymarket-based markets (sourced from the Polygon order book); for other venues we list platform attributes, since the comparable contracts are not exposed via a public API on every venue. Every CTA points at PolyGram — the application we operate, where you trade directly against the Polymarket order book at 0% fees.
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.
- Do I need to KYC for this market?
- Not under $1,500 of lifetime trading volume. Above that threshold, PolyGram triggers a quick verification flow that finishes in minutes.
- 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.
