Market outcomes
| ITF Wuning: Uisung Park vs Noritaka Koizumi | 51% YES | 49% NO |
| Completed Match | 50% YES | 50% NO |
Uisung Park and Noritaka Koizumi are scheduled to meet in the ITF Men's Wuning tournament on 14 May 2026. The match currently trades at 50–50 on Polymarket's order book, reflecting genuine uncertainty between two players with limited recent comparative data at this tier. The settlement window extends to 21 May, allowing a seven-day buffer for rescheduling without triggering a 50–50 resolution, though cancellation or abandonment mid-match would also resolve to even odds.
ITF Men's circuit matches at this level typically feature players ranked outside the ATP top 200, where form fluctuates considerably and head-to-head records carry limited predictive weight. Park, a South Korean player, and Koizumi, competing from Japan, have sparse recent tournament history available through standard databases. The 50–50 pricing suggests the market has insufficient edge data to favour either competitor, with order flow likely driven by small position-building rather than informed directional conviction.
Traders should monitor ITF tournament draws and player withdrawal announcements through the official ITF website in the week preceding 14 May, as scheduling changes and late scratches are common at satellite level. Recent injury reports or qualifying-round performance from either player would shift the probability, though such information rarely surfaces until days before play. Surface conditions at the Wuning venue and weather forecasts closer to the date may also influence match completion risk, particularly given the seven-day delay clause that could activate if weather disrupts the schedule.
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: Uisung Park vs Noritaka Koizumi" 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.
$0 in lifetime turnover and $59 of resting liquidity puts this market in the below the median by volume for games 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.
