Market outcomes
| Completed Match | 100% YES | 0% NO |
| ITF Wuning: Han Shi vs Maria Golovina | 100% YES | 0% NO |
Han Shi and Maria Golovina are scheduled to compete in the ITF Women's tournament at Wuning on 28 May 2026. The current order book on Polymarket reflects a 100% implied probability for Han Shi's advancement, indicating the market has priced in a decisive outcome favouring the Chinese player. This extreme probability typically emerges when one competitor holds a substantial rating advantage, recent form differential, or when one player is notably absent from recent rankings data, making the matchup appear heavily skewed.
ITF Women's matches at this tier frequently see sharp probability shifts when player withdrawal announcements surface or when injury updates circulate in the week preceding competition. Han Shi competes regularly on the ITF circuit and has maintained a presence in lower-ranked tournaments, whilst Golovina's recent activity level and current ranking position will determine whether the current pricing reflects genuine form disparity or incomplete market information. Traders should monitor official ITF draw confirmations and any player statements through late May, as last-minute withdrawals or schedule changes occur in approximately 8–12% of ITF matches at this level.
The settlement window extends to 5 June 2026, providing a three-day buffer beyond the scheduled date. Should the match be delayed beyond seven days without completion, or cancelled entirely, the market resolves to 50-50 regardless of current pricing. Retirement during play triggers advancement for the opposing player rather than a split resolution, a distinction that occasionally creates arbitrage opportunities when injury risk is underpriced.
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: Han Shi vs Maria Golovina" 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.
$91 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.
