Market context
Viktorija Golubic and Veronika Erjavec are scheduled to compete in the opening round of Nottingham Open qualifying on 13 June 2026. Golubic, a Swiss player ranked in the mid-200s on the WTA, has competed regularly on the ITF and secondary tour circuit over recent seasons, with occasional main-draw appearances at established events. Erjavec, a Slovenian competitor, operates primarily within the qualifying and ITF sphere, where she has accumulated modest wins but limited breakthrough performances at higher levels.
The 100% crowd probability reflects Golubic's superior ranking and experience at this tier of competition. Historically, qualifying matches between players of notably different ranking positions—particularly when one sits substantially higher on the WTA ladder—settle heavily toward the favoured player, though upsets remain possible in single-elimination tennis where form, draw luck, and surface suitability matter considerably. Qualifying rounds at established grass-court events like Nottingham often produce tighter contests than their ranking differentials suggest, given the specialised nature of grass preparation and the compressed schedule.
Traders should monitor official Nottingham Open draws and any withdrawal announcements through the WTA website or tournament communications in the days preceding 13 June. Injury updates or late scratches could alter the match composition entirely. The settlement window extends to 20 June, allowing seven days for rescheduling should weather or other disruptions occur; matches delayed beyond that threshold without completion would trigger the 50-50 resolution clause.
Methodology
This page reviews Nottingham Open, Qualification: Viktorija Golubic vs Veronika Erjavec across five venues. We show live odds for Polymarket-based markets (sourced from the Polygon order book); for other venues we list platform attributes, since the comparable contracts are not exposed via a public API on every venue. Every CTA points at Sport Prediction — the application we operate, where you trade directly against the Polymarket order book at 0% fees.
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.
