Market outcomes
| ITF Gimcheon: Dong Ju Kim vs Matthew Dellavedova | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Dong Ju Kim and Matthew Dellavedova are scheduled to meet in the ITF Men's Gimcheon tournament on 30 May 2026. The market currently reflects zero probability for Kim's advancement, with the order book showing no meaningful backing for his victory. This pricing appears extreme given both players' professional status on the ITF circuit, where upsets and competitive matches are routine occurrences.
Kim, a South Korean player competing primarily on ITF futures tours, faces Dellavedova, an Australian with prior ATP experience and established ranking history. The 0% probability for Kim's win suggests the market has incorporated strong conviction about Dellavedova's superiority, though ITF matches frequently produce results that defy such polarised assessments. Historical ITF tournament data shows that lower-ranked players advance in roughly 15–25% of matches against higher-ranked opponents, depending on the specific ranking gap and surface conditions. Without confirmed seeding or recent head-to-head records between these players, the current pricing warrants scrutiny.
Traders should monitor tournament draw confirmations and any player withdrawal announcements as the May 30 date approaches. Surface conditions at the Gimcheon venue—typically hard court—and recent form indicators from both players' preceding ITF matches will provide concrete data for reassessing the probability. The settlement window extends to 7 June, allowing for potential delays, though cancellations or incomplete matches would trigger a 50-50 resolution under the market's terms.
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 Matthew Dellavedova" 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.
$7K 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.
