Market context

Polina Kudermetova and Xiyu Wang are due to meet in Roland Garros qualifying, with the market currently showing 0% YES for Kudermetova. That makes Wang the clear favourite by the tape, although the market is still pricing in the usual uncertainty around qualifying draws, where form lines can move quickly from round to round. For context, the pair have already met once in professional competition, with Kudermetova leading that head-to-head 1-0, but Wang has the cleaner recent Roland Garros qualifying run and has not dropped a set so far, while Kudermetova has conceded one. On that basis, the consensus sits with Wang advancing, while the contrarian angle is a Kudermetova upset if the match becomes a longer, serve-dominated contest.

The most important trader watchpoints are simple: whether the match is played on schedule, whether any court-time changes affect preparation, and whether either player carries over fatigue from the previous qualifying rounds. Both players started in qualifying and have already completed two matches, so scheduling and recovery matter as much as raw ranking. Recent market listings and live-score pages show the fixture as active on 22 May, which suggests it is still in the normal pre-match phase rather than a cancellation risk, but any delay beyond seven days would push the market to the tie rule. In handicap terms, the favourite is Wang, the value is more likely on a lower-priced Wang win than on the current 0% Kudermetova line, and any Kudermetova case rests on H2H precedent rather than current consensus.

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

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.
