Market context

The Nottingham Open grass-court fixture between Sara Bejlek and Karolina Pliskova is scheduled for 16 June 2026 at 9:00 AM ET. The 100% crowd probability reflects the match's confirmed status on the WTA calendar, though this reflects scheduling certainty rather than a prediction of outcome. No material changes to player availability or tournament logistics have emerged in the past 48 hours.

Pliskova, a former world number one and two-time Grand Slam finalist, carries significant pedigree on grass surfaces, having reached Wimbledon semi-finals and competed consistently at elite level across multiple seasons. Bejlek, by contrast, operates at a lower ranking tier and has limited documented grass-court performance data at professional level. Historical precedent suggests that when established top-50 players face lower-ranked opponents on specialist surfaces like grass, the higher-ranked player advances in roughly 75–80% of cases, though upsets occur regularly enough to merit consideration.

Traders should monitor the official Nottingham Open draw confirmation and any late withdrawals or injury announcements from either player in the week leading to 16 June. Grass-court conditions at Nottingham typically favour serve-dominant players and those with quick court movement. Weather forecasts for mid-June in the Midlands may also influence playing conditions. The settlement window closes 23 June, allowing a seven-day buffer for rescheduling if weather delays occur. Any announcement of a player's withdrawal would trigger the 50-50 resolution clause.

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.
