Market context

Tereza Valentova, the Czech qualifier, faces Polish veteran Magda Linette in an early-round Roland Garros women's singles match scheduled for 24 May 2026. The 0% implied probability on this contract reflects either extreme confidence in Linette's superiority or a data gap in the prediction market's assessment relative to conventional sportsbooks. Linette, ranked significantly higher and with multiple Grand Slam main-draw appearances to her name, enters as the clear favourite; however, the complete absence of YES probability warrants scrutiny against actual betting lines and analyst consensus.

Historically, qualifier-versus-seeded-player matchups at Roland Garros show modest upset rates—roughly 15–20% across comparable skill gaps—though Linette's recent form and court-surface preference matter considerably. Valentova's path through qualifying would signal her current fitness and confidence levels; conversely, Linette's preparation schedule and any recent injury concerns could shift the baseline expectation. The settlement window extends to 31 May, allowing seven days beyond the scheduled date for completion, which accommodates typical tournament delays but creates resolution risk if the match is postponed indefinitely.

Traders should monitor official Roland Garros draw confirmations, any late withdrawals, and court assignments once the schedule is published. Linette's recent performance at clay-court events and Valentova's qualifying results will provide concrete data points for recalibrating the current zero probability. Sportsbook opening lines, typically available 48–72 hours before play, will offer a direct comparison to this market's current consensus.

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.
