Market outcomes
| ITF Kursumlijska Banja: Rasheeda McAdoo vs Lisa Zaar | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Rasheeda McAdoo and Lisa Zaar are scheduled to compete in the ITF Women's tournament at Kursumlijska Banja on 27 May 2026. The match is set for 4:00 AM ET, part of the lower-tier ITF circuit where both players compete regularly. The current order book on Polymarket reflects a 0% implied probability for McAdoo's victory, indicating the market is pricing in either strong confidence in Zaar's superiority or substantial uncertainty about match completion.
ITF tournaments at this level frequently experience scheduling disruptions, weather delays, and player withdrawals, particularly when matches are scheduled at unconventional hours. Historical patterns suggest that matches delayed beyond the original date without completion often resolve to 50-50 splits rather than decisive outcomes. The settlement window extends to 3 June 2026, providing a five-day buffer for rescheduling, though matches delayed more than seven days from the original date trigger the tie resolution clause.
Traders should monitor ITF tournament announcements and draw sheet updates as the event approaches, particularly regarding weather forecasts for the Kursumlijska Banja region and any player injury reports. McAdoo's recent form and head-to-head record against Zaar, if available through WTA or ITF databases, would provide context for why the market has priced her at zero probability. The extreme pricing suggests either a significant ranking or form differential between the players, or material doubt about whether the match will be contested at all.
This market settles from the official outcome published at https://www.itftennis.com/en/tournament-calendar/. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.

Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
