Market outcomes
| ITF Gimcheon: Dong Ju Kim vs Harry Roberts | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
The ITF Men's Gimcheon tournament is scheduled to run in late May 2026, with Dong Ju Kim facing Harry Roberts in what appears to be an early-round fixture. The current order book on Polymarket reflects a 100% implied probability for Kim's advancement, suggesting either substantial backing for the South Korean player or minimal liquidity at present price levels. This extreme probability typically indicates either asymmetric information favouring one player or insufficient trading volume to establish a competitive spread.
Historical ITF Men's matches at this tier show considerable variance in outcomes, particularly when one player holds a significant ranking advantage or has recent tournament momentum. Kim's domestic ranking and recent ITF performance record would be primary factors determining whether the current probability reflects genuine edge or merely thin liquidity. Roberts' recent results on the ITF circuit, including any qualifying rounds or recent tournament appearances, would provide context for assessing whether the market has properly priced his chances.
Key catalysts include official tournament draw confirmation closer to the event date, any player withdrawals or injury announcements in the weeks preceding late May, and weather conditions at the Gimcheon venue which could affect scheduling. The seven-day delay clause in the settlement terms creates additional risk; traders should monitor ITF's official website and the ATP's injury/withdrawal announcements. Recent ITF tournament reports indicate scheduling reliability has improved, though weather disruptions remain possible in South Korea during late May.
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 Gimcheon: Dong Ju Kim vs Harry Roberts" 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.
$55 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.
