Market outcomes
| ITF Gimcheon: Uisung Park vs Yeongseok Jeong | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Uisung Park and Yeongseok Jeong are scheduled to meet in the ITF Men's Gimcheon tournament on 27 May 2026 at 11:00 PM ET. The current order book on Polymarket reflects a 100% implied probability for the match occurring and producing a decisive result, with no material uncertainty priced in at present. This extreme confidence suggests either strong conviction that the match will proceed as scheduled, or insufficient liquidity to move the probability away from the extremes.
ITF Men's circuit matches at this level carry a modest cancellation and withdrawal rate, typically between 2–5% depending on weather, injury, or scheduling conflicts. Recent ITF tournaments in South Korea have maintained relatively stable schedules, though spring weather in Gimcheon can introduce rain delays. Neither player has a documented history of late withdrawals, though injury status closer to the event date remains unknowable at this distance.
Key catalysts for traders include official ITF tournament updates, any player injury announcements in the weeks before 27 May, and weather forecasts as the date approaches. The settlement window closes 4 June 2026, allowing a seven-day buffer for rescheduling before the market resolves to 50-50. Current pricing leaves no room for perceived execution risk, suggesting traders should monitor ITF Gimcheon draw confirmations and player ranking updates as potential triggers for repricing.
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 current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$38 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.
