Market outcomes
| ITF Oliva: Sara Dols vs Carolin Raschdorf | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Sara Dols and Carolin Raschdorf are scheduled to compete in the ITF Women's circuit event in Oliva on 28 May 2026. The match is set for 4:30 AM ET, part of the lower-tier professional tennis calendar where both players typically compete to accumulate ranking points and match experience. The current order book on Polymarket reflects a 100% implied probability for resolution, suggesting either exceptionally high confidence in match completion or minimal trading volume establishing price discovery at the extremes.
ITF Women's matches at this tier carry a historical completion rate above 95%, with withdrawals typically announced 24–48 hours before scheduled play rather than on match day. Comparable events on the Oliva circuit show consistent scheduling adherence, though weather delays and player injury withdrawals do occur. The seven-day grace period built into the settlement terms accounts for rescheduling common in lower-tier professional tennis, where tournament logistics are less rigid than ATP or WTA events.
Traders should monitor official ITF and tournament communications for any withdrawal announcements, which typically emerge in the week preceding the match. Dols and Raschdorf's recent match records and injury status—available through WTA and ITF databases—will signal confidence levels in participation. The 4:30 AM ET start time is unusual for European events and warrants verification against the official tournament schedule, as scheduling errors occasionally appear in preliminary draws. Settlement occurs on 4 June 2026, allowing a one-week window for delayed completion or administrative resolution.
