Market outcomes
| Completed Match | 100% YES | 0% NO |
| ITF Gimcheon: Chan-Yeong Oh vs Jaesung Choe | 100% YES | 0% NO |
Chan-Yeong Oh and Jaesung Choe are scheduled to compete in the ITF Men's Gimcheon tournament on 25 May 2026. The match represents a lower-tier professional tennis fixture on the ITF circuit, where both players are competing for ranking points and prize money. The current orderbook on Polymarket reflects a 100% implied probability for resolution, indicating traders are pricing in near-certainty that the match will be completed and produce a decisive winner by the settlement deadline of 2 June 2026.
ITF Men's events at this tier typically proceed as scheduled unless weather or injury intervenes substantially. Historical patterns across comparable ITF tournaments show cancellation rates below 5%, with most matches reaching completion within the scheduled window. The 7-day buffer built into the resolution criteria provides meaningful protection against minor delays, though rain disruptions at Korean venues in late May are not uncommon. Traders should note that the 100% probability reflects confidence in match completion rather than a prediction of either player's victory; the orderbook would typically split this probability between the two competitors once trading activity begins in earnest.
Key catalysts include weather forecasts for Gimcheon in the week preceding 25 May, any injury announcements from either player's camp, and confirmation of the tournament draw. ITF scheduling information is typically published 10–14 days before competition begins. Traders should monitor official ITF and tournament communications for fixture changes, as administrative delays occasionally push matches beyond their original time slots without triggering the tie-resolution clause.

$2K 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.
