Market outcomes
| ITF Luan: Tianhui Zhang vs Weiyi Kong | 100% YES | 0% NO |
| Completed Match | 0% YES | 100% NO |
Tianhui Zhang and Weiyi Kong are scheduled to compete in the ITF Men's Luan tournament on 27 May 2026 at 11:00PM ET. The current order book on Polymarket reflects a 100% implied probability for Zhang's advancement, suggesting the market has priced in either strong conviction regarding his form or a significant information asymmetry about one player's status. This extreme probability is unusual for a match between two active ITF competitors and warrants scrutiny of the underlying assumptions driving the pricing.
ITF Men's circuit matches at the Luan event typically feature players ranked outside the ATP top 200, where form volatility and injury status can shift rapidly. Historical precedent shows that 100% probabilities on Polymarket for tennis matches rarely hold through to settlement unless one player withdraws or is confirmed injured beforehand. The settlement window extends to 4 June 2026, providing a week beyond the scheduled date for match completion, which reduces the likelihood of a 50-50 resolution due to postponement alone.
Traders should monitor official ITF and tournament communications for any withdrawal announcements, injury disclosures, or schedule changes in the days preceding 27 May. Recent tournament schedules for ITF events have been subject to weather delays and venue adjustments, particularly in May. The extreme probability currently reflected in the order book suggests either Zhang is heavily favoured based on recent ranking movements or Kong's participation status is in question—verification of both players' confirmed entry into the draw would be a critical catalyst for any position adjustment.
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.

$2K 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.
