Market outcomes
| ITF Gimcheon: Sanhui Shin vs Dong Ju Kim | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
The ITF Men's Gimcheon tournament will feature a first-round match between South Korean players Sanhui Shin and Dong Ju Kim on 29 May 2026. The current order book on Polymarket shows zero probability assigned to Shin's advancement, reflecting either minimal trading activity or strong market conviction favouring Kim. With the settlement window closing on 6 June, traders have a narrow window to assess form, recent results, and any late withdrawals or scheduling changes that might affect the fixture.
Both players compete regularly on the ITF circuit, where outcomes can shift substantially based on recent match fitness and surface preference. Gimcheon's hard court conditions and the tournament's May timing provide context for assessing which player's recent performances are most relevant. Historical ITF matchups between Korean domestic competitors often see modest trading volumes, which may explain the current extreme pricing; markets with thin liquidity frequently display probabilities disconnected from underlying match fundamentals.
Key catalysts include any injury announcements or withdrawal notices from either player in the week preceding the match, official confirmation of the tournament schedule, and any head-to-head records or recent tournament results that emerge as the date approaches. Traders should monitor ITF rankings updates and player social media for fitness indicators. The seven-day delay clause means matches postponed beyond 6 June would trigger a 50-50 resolution, creating additional settlement risk distinct from the match outcome itself.
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: Sanhui Shin vs Dong Ju Kim" 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.
$9K 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.
