Market outcomes
| ITF Kursumlijska Banja: Teodora Kostovic vs Laura Samson | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Teodora Kostovic faces Laura Samson in the ITF Women's tournament at Kursumlijska Banja, scheduled for 29 May 2026. The current order book on Polymarket shows zero probability for a Kostovic victory, reflecting either strong backing for Samson or minimal trading activity at present. With settlement occurring on 5 June 2026, traders have approximately one week from the match date to assess the outcome, though the 7-day delay clause introduces resolution ambiguity if the fixture is postponed.
ITF Women's tournaments at smaller venues typically feature lower-ranked players with limited historical data. Kostovic and Samson's head-to-head record, ranking trajectories, and recent form on hard courts remain the primary inputs for assessing match probability. The 0% YES reading suggests either that Samson has demonstrated clear superiority in comparable fixtures or that the market has simply not attracted sufficient liquidity to establish a balanced price. Without recent tournament results or ranking shifts from either player, the current probability may reflect incomplete information rather than definitive competitive advantage.
Traders should monitor ITF official announcements regarding match confirmation, court conditions, and any withdrawal notices prior to 29 May. Weather disruptions in Serbia during late May could trigger the 7-day delay clause, forcing resolution to 50-50 if no winner emerges within the specified window. Fixture cancellations, though uncommon, would similarly resolve the market to even odds. The thin order book suggests this market may lack depth; liquidity conditions could shift sharply if either player's recent results become public.
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 Kursumlijska Banja: Teodora Kostovic vs Laura Samson" 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.
$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.
