A tennis match between Lanlana Tararudee and Xinxin Yao is scheduled for 7 May 2026 in Jiujiang as part of the professional circuit. The market resolves to the winner of the completed match, with a 50-50 split if the fixture is cancelled, delayed beyond seven days without resolution, or ends in a tie.
The 0% implied probability reflects limited trading activity or data availability on these competitors at this stage. Both players operate primarily on the ITF and secondary professional circuits, where match records and head-to-head history remain sparse in mainstream databases. Without established ranking positions or recent tournament results in major databases, traders lack conventional reference points for assessing relative strength. Historical precedent suggests that matches between lower-ranked or less-publicised players often see minimal market participation until closer to event dates, when travel confirmations and late withdrawals become clearer.
Key variables affecting settlement include fixture confirmation as the May date approaches, player injury or withdrawal announcements, and weather conditions in Jiujiang during early May. The seven-day delay clause creates material risk; Chinese domestic tournaments occasionally face rescheduling due to logistical constraints. Traders should monitor official tournament draws and player social media for withdrawal notices, which typically emerge 48–72 hours before matches. The settlement window closes 7 May at 02:00 UTC, allowing minimal time for delayed matches to resolve within the contract terms.
This market settles from the official outcome published at https://www.wtatennis.com/scores. 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 "Jiujiang: Lanlana Tararudee vs Xinxin Yao" 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.
$297K in lifetime turnover and $0 of resting liquidity puts this market in the top 10% 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.
Resolution is sourced from https://www.wtatennis.com/scores. Settlement is executed by the UMA optimistic oracle on Polygon, with a 2-hour dispute window before payouts clear.
This prediction market is scheduled to close on 15 May 2026. After the resolving event occurs, settlement typically clears within 24 hours once the UMA optimistic oracle confirms the outcome. All payouts are in USDC on the Polygon network.
