Market outcomes
| Completed Match | 100% YES | 0% NO |
| ITF Doboj: Dusan Obradovic vs Eric Vanshelboim | 0% YES | 100% NO |
An ITF Men's tournament match scheduled for 24 May 2026 in Doboj, Bosnia and Herzegovina, pits Serbian player Dusan Obradovic against French competitor Eric Vanshelboim. The current order book on Polymarket reflects a 100% implied probability for Obradovic's advancement, suggesting the market has priced in either a strong expectation of his victory or material uncertainty regarding match completion. Settlement occurs by 31 May 2026, allowing a seven-day window beyond the scheduled date for the match to conclude.
ITF Futures events at this level typically feature volatile participant availability and occasional withdrawals, particularly when players receive late-stage opportunities in higher-ranking tournaments. Historical precedent shows that matches at regional ITF venues in Eastern Europe experience cancellation or postponement rates of 3–8% due to logistical constraints or player injury. The 100% probability currently displayed suggests either incomplete market information or that traders have already factored in Obradovic's participation as near-certain, though the extreme reading warrants caution given typical ITF scheduling uncertainties.
Traders should monitor official ITF and ATP communications for any withdrawal announcements from either player, particularly if either receives a call-up to concurrent Challenger or ATP events. Weather conditions in Doboj during late May occasionally affect clay court scheduling. The resolution mechanism's 50-50 tie-break for incomplete matches or delays beyond seven days creates a discrete risk boundary; any disruption extending past 31 May would trigger this clause regardless of match status.
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 Doboj: Dusan Obradovic vs Eric Vanshelboim" are the same as any other PolyGram sporting 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.
$1K in lifetime turnover and $0 of resting liquidity puts this market in the below the median by volume for sports 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.
