Market context

Martyna Kubka’s quarter-final against Yeon-Woo Ku in Figueira da Foz is priced at **0% YES** in this market, which is far below what a live tennis board or a pre-match sportsbook would usually show for a scheduled match. The public match pages confirm the fixture exists as a WTA 125 quarter-final, but they do not show an obvious history between the pair, and one live-score source notes there is **no previous head-to-head data** between them.[4][2] In practice, that makes the contract unusually sensitive to whether the match is actually completed rather than to any clear pre-match edge, because a 0% prediction-market price implies the crowd is effectively treating the “Kubka advances” outcome as near-impossible.

Comparable cases suggest that extreme prediction-market pricing often reflects event status risk, not pure tennis ability. When a market is near zero on a player outcome, traders are usually pricing in either a withdrawal, a walkover, or late schedule disruption, especially in smaller ITF/WTA 125 events where order-of-play changes are common and detailed market-moving information can arrive after bookmakers have already adjusted. Tennis.com’s event listing still shows the match as a quarter-final, while TennisMajors also has the tie listed, which supports that the relevant uncertainty is about fulfilment and completion rather than whether the pairing was ever drawn.[4][5]

The main catalysts are the tournament order of play, any last-minute injury or retirement notices, and whether the match begins before the settlement window closes. Because this contract resolves to **50-50** if the match is cancelled, tied, or delayed beyond seven days without a winner, a trader should watch for official draw updates and walkover language rather than only scorelines; once a match starts, retirement rules become decisive under the market description. On the current information, analyst-style match pages do not show a consensus price strong enough to explain a 0% YES reading, so the main divergence is between a near-zero prediction-market line and the fact that the fixture remains listed as live and scheduled.[2][4][5]

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
