Market outcomes
| ITF Wuning: Sijia Wei vs Jiaqi Wang | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Sijia Wei and Jiaqi Wang are scheduled to compete in the ITF Women's Wuning tournament on 28 May 2026 at 1:15 AM ET. The market currently shows 0% implied probability for Wei's advancement, reflecting the order book's assessment on Polymarket. This extreme positioning suggests either a heavily favoured Wang in the eyes of current traders, or minimal liquidity establishing a floor price rather than genuine conviction. The settlement window extends to 4 June 2026, allowing seven days from the scheduled date for the match to conclude.
ITF Women's circuit matches at this tier frequently feature players with limited historical head-to-head records and sparse public ranking data. Wei and Wang are both Chinese nationals competing on the lower-tier professional circuit, where match outcomes can be volatile and prior form less predictive than on the WTA main tour. Comparable ITF events show that crowd-implied probabilities of 0% or near-zero typically reflect either a clear ranking or seeding advantage to one player, or simply the absence of early trading activity establishing a baseline.
Traders should monitor ITF Wuning's official draw confirmation and any injury announcements in the days preceding 28 May. Weather disruptions at the venue could trigger the seven-day delay clause, potentially forcing a 50-50 resolution. Recent ITF tournament schedules have generally proceeded as scheduled, though withdrawals remain common at this level. The current zero probability may shift materially once the draw is published and player form closer to the event date becomes available.
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.

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.
