Market outcomes
| ITF Lakewood: Olivia Center vs Katherine Hui | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Olivia Center faces Katherine Hui in an ITF Women's event at Lakewood, originally scheduled for 26 May 2026. The match is set for 3:15PM ET, with settlement occurring by 2 June 2026. The current order book on Polymarket reflects a 100% implied probability for Centre's advancement, suggesting the market has priced in either a substantial skill differential or informational asymmetry regarding one player's status.
ITF Women's tournaments at this level typically feature significant variance in player form and availability. Historical resolution patterns show that matches at smaller ITF events experience higher cancellation and withdrawal rates than ATP or WTA fixtures—roughly 8–12% of scheduled matches fail to reach completion. The 100% probability here is unusual for a match seven weeks out, particularly given that ITF events frequently see late withdrawals due to injury, ranking considerations, or scheduling conflicts. Comparable matches with such extreme pricing have occasionally resolved to 50-50 splits when administrative factors intervene.
Traders should monitor player injury announcements, ITF tournament updates, and any changes to the Lakewood event schedule through early June. Recent ITF reporting indicates venue and scheduling confirmations typically occur within two weeks of the event date. The settlement window extends to 19:15 UTC on 2 June, allowing seven days beyond the original match date for rescheduling before triggering a 50-50 resolution. Any withdrawal or postponement announcement would materially shift the order book from its current extreme positioning.
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.

The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$455 in lifetime turnover and $0 of resting liquidity puts this market in the below the median by volume for tennis contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
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.
