Market outcomes
| ITF Lakewood: Jo-Yee Chan vs Allison Wang | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Jo-Yee Chan and Allison Wang are scheduled to compete in the ITF Women's tournament at Lakewood on 27 May 2026. The match represents a lower-tier professional event within the International Tennis Federation circuit, where both players typically compete for ranking points and prize money. The current order book on Polymarket reflects zero probability for Chan's advancement, suggesting either substantial uncertainty about match completion or a market assessment heavily favouring Wang based on recent form or head-to-head record.
ITF Women's matches at this level frequently involve players ranked outside the WTA top 200, where historical data on direct matchups can be sparse. The 0% implied probability warrants scrutiny—such extreme valuations often emerge when one player has demonstrable recent form advantages, injury concerns affecting the other, or when limited trading liquidity has allowed a single position to anchor the order book. Comparable ITF events show that upsets occur regularly enough that absolute certainties are rare, particularly when player rankings are proximate.
Traders should monitor official ITF and tournament announcements through late May for any withdrawal declarations, injury updates, or schedule changes. Weather disruptions at outdoor clay or hard courts in the Lakewood area could trigger the seven-day delay clause leading to 50-50 resolution. Recent tournament results for both players in the weeks preceding 27 May will provide concrete form data; any significant injury news or withdrawal from preceding events would materially shift the current market consensus.
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 Lakewood: Jo-Yee Chan vs Allison Wang" 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.
$564 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.
