Market outcomes
| ITF Wuning: Zongyu Li vs Ekaterina Yashina | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Zongyu Li, a Chinese ITF competitor, faces Ekaterina Yashina in a women's singles match at the ITF Women's Wuning tournament scheduled for 26 May 2026. The current order book on Polymarket reflects a 100% implied probability for Li's advancement, suggesting the market has priced in either a strong expectation of her victory or material uncertainty regarding match completion. This extreme probability warrants scrutiny given the seven-day settlement window extending to 2 June 2026, which creates ambiguity around fixture delays or cancellations.
ITF Women's circuit matches at this level typically feature significant variance in player form and availability. Yashina, a Russian player competing on the ITF tour, represents a known opponent with documented match history. The 100% probability is unusual for a competitive tennis match and may reflect incomplete information in the market, liquidity constraints on Polymarket's order book, or early-stage pricing before fuller trader participation. Historical ITF tournaments show that fixture disruptions—weather delays, player withdrawals, or scheduling conflicts—occur with measurable frequency, particularly for lower-ranked events.
Traders should monitor official ITF tournament announcements and draw sheet confirmations as the match date approaches. Any player injury reports, withdrawal notices, or weather forecasts for the Wuning venue in late May would materially shift the probability. The resolution mechanism's 50-50 tie provision for matches delayed beyond seven days creates a discrete risk factor distinct from match outcome itself. Current pricing leaves no margin for these contingencies, suggesting either mispricing or thin liquidity on the order book.
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 mechanics for trading "ITF Wuning: Zongyu Li vs Ekaterina Yashina" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$7K 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.
