| Completed Match | 100% YES | 0% NO |
Aurora Zantedeschi and Valentina Ivanov are scheduled to compete in the ITF Women's tournament at Bol, Croatia on 31 May 2026. The match is set for 4:00 AM ET. The current order book on Polymarket reflects a 100% implied probability for Zantedeschi's advancement, indicating the market has priced in either strong conviction around her prospects or limited liquidity at the current price level. Settlement occurs by 7 June 2026, allowing a six-day window for the match to conclude.
ITF Women's events at this tier typically feature players ranked outside the WTA top 200, often competing for ranking points and prize money in the €25,000–€100,000 range. Historical precedent suggests matches at Bol rarely cancel outright; the venue has maintained consistent scheduling. However, weather disruptions on the Croatian coast during late May occur occasionally, and player withdrawals at ITF level run higher than on the main tour. Comparable tournaments show that extreme probability skew—such as the current 100% reading—often reflects either a significant seeding disparity or minimal trading volume rather than certainty of outcome.
Traders should monitor ITF entry lists and any player withdrawal announcements in the week before the scheduled date. Recent form and head-to-head records between these players remain relevant catalysts; ITF databases and WTA Insider typically publish updated rankings and match histories. Court surface conditions at Bol and any late schedule changes would also influence execution, particularly given the early morning start time which may affect player availability or performance.
