Market context

The Libema Open grass-court tournament in 's-Hertogenbosch will host a second-round encounter between Czech world number 4 Barbora Krejcikova and Polish competitor Magda Linette, scheduled for 13 June 2026. Krejcikova arrives as the tournament's highest-ranked player and a three-time Grand Slam doubles champion with proven grass-court credentials, whilst Linette, currently ranked around 40th, qualified through the draw. The 100% implied probability reflects Krejcikova's substantial ranking advantage and historical dominance in head-to-head matchups.

Krejcikova's record against lower-ranked opponents on grass surfaces provides the baseline for evaluating this market. Her 2021 Wimbledon run and consistent performance at Birmingham and 's-Hertogenbosch prior editions demonstrate comfort on fast courts. Linette has won only one WTA title and lacks comparable grass-court specialisation, though she defeated higher-ranked players in 2024. Historical precedent suggests upsets at this level occur in roughly 8–12% of matches where ranking differential exceeds 30 positions, though grass surfaces compress these probabilities further.

Traders should monitor withdrawal announcements through the ATP/WTA injury report system and tournament draw confirmations released typically 48 hours before play. Weather delays at 's-Hertogenbosch—common in June—could trigger the settlement tie-break if matches extend beyond the seven-day window. Conditional order logic should account for the 50-50 resolution clause; automated systems tracking tournament schedules will flag any rescheduling beyond 20 June 2026 08:00 UTC as a critical trigger point.

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 Polymarket Bot UK, 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.
