Market context

The Nottingham Open grass-court tournament will host a first-round match between Ukrainian player Dayana Yastremska and German veteran Tatjana Maria on 17 June 2026. Yastremska, ranked in the top 30 on the WTA tour, faces Maria, a former top-10 player who has maintained a presence on the professional circuit despite taking time away for motherhood. The match is scheduled for 5:00 AM ET, placing it in an early slot typical of opening rounds at smaller grass tournaments.

Historical precedent suggests that 100% crowd-implied probability on a scheduled match reflects near-certainty of play rather than a prediction of outcome. Across comparable WTA 250-level events, matches scheduled at established venues like Nottingham rarely fail to occur unless weather or injury intervenes within 48 hours of start time. The Nottingham Open has maintained consistent scheduling since its 2015 revival, with cancellations typically limited to weather delays rather than outright withdrawals. Both players have competed regularly through 2025, with no reported chronic injury concerns that would suggest late withdrawal.

Traders monitoring this market should track official tournament updates and player social media for injury announcements, which typically emerge 24–48 hours before play. Grass-court preparation schedules matter here: players often adjust their warm-up intensity in the week before Nottingham. The settlement window extends to 24 June, allowing a seven-day buffer for rescheduling if weather disrupts the original date. For automated systems, the key dependency is confirmation of match completion rather than prediction of winner—the 50-50 resolution clause for incomplete matches or delays beyond seven days creates a distinct risk profile separate from head-to-head performance modelling.

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.
