Market context

The real-world event is a women’s singles tennis match at the Lexus Eastbourne Open, scheduled for 5:00 AM ET on 23 June 2026 at Devonshire Park in Eastbourne, UK. This tournament, held on outdoor grass courts from 22 to 27 June 2026, is a WTA 250 event on the 2026 WTA Tour [2][4]. In prediction markets, a YES share pays out if the named outcome occurs—here, if Yulia Starodubtseva advances past Anastasia Zakharova—while a NO share pays if it does not. The current crowd-implied probability of YES is 0%, suggesting the market believes Starodubtseva is highly unlikely to win this match.

Historically, 0% probabilities in tennis markets often precede either a player’s withdrawal, a severe injury, or a mismatch in form or surface suitability. For example, in prior WTA grass-court events, players with no recent grass experience or those returning from injury have seen probabilities collapse to near-zero before matches were either not played or lost decisively [2]. Such cases frame how to interpret today’s 0%: it likely reflects a structural disadvantage for Starodubtseva rather than a temporary fluctuation.

Traders should monitor official draw confirmations, player health announcements, and any schedule changes from the tournament organisers. The roster for Eastbourne 2026 has not yet been fully released, and matches typically begin at 11:00 AM local time, though the specific match time may shift [3]. A recent update from the WTA confirms the tournament runs on grass with a 32-player singles draw, meaning surface adaptability is critical [4]. Any news indicating Starodubtseva’s withdrawal or a delay beyond seven days would trigger the market’s 50-50 resolution clause, so timely updates from official sources are essential.

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
