Market outcomes
| ITF Gimcheon: Naoki Tajima vs Dongjae Kim | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Naoki Tajima and Dongjae Kim are scheduled to compete in the ITF Men's Gimcheon tournament on 26 May 2026. The match represents a lower-tier professional tennis fixture on the ITF circuit, where both players typically compete for ranking points and prize money. The current orderbook on Polymarket reflects a 100% implied probability for resolution, suggesting traders are pricing near-certainty that the match will occur and produce a decisive winner by the settlement deadline of 3 June 2026.
ITF Men's events at this tier historically feature high completion rates, with matches rarely cancelled outright or extending beyond scheduled dates without resolution. The probability formation reflects standard assumptions about fixture stability at this level—weather disruptions are uncommon in late May in South Korea, and both players have demonstrated reliability in completing scheduled matches. Comparable ITF tournaments show cancellation rates below 2%, making the current pricing consistent with baseline tournament execution risk.
Key catalysts for traders include any official ITF or tournament announcements regarding scheduling changes, player withdrawals, or venue issues. Injury updates on either player in the weeks preceding the match would shift market pricing materially. The settlement window extends seven days beyond the scheduled date, providing buffer for minor delays, though matches at this level typically conclude on their assigned day. Traders should monitor the ITF's official website and tournament draw updates for any administrative changes that might affect fixture certainty.
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.

$1K 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.

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.
