Market outcomes
| ITF Kursumlijska Banja: Gala Ivanovic vs Laura Samson | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Gala Ivanovic and Laura Samson are scheduled to compete in the ITF Women's circuit event at Kursumlijska Banja on 26 May 2026. The match represents a lower-tier professional tennis fixture where both players will be competing for ranking points and prize money. The current order book on Polymarket reflects a 0% implied probability for Ivanovic's advancement, suggesting traders have positioned entirely on Samson or are awaiting additional information before committing capital to either side.
ITF Women's matches at this tier typically feature players ranked outside the WTA's top 200, with outcomes heavily influenced by recent form, surface preference, and head-to-head records. Historical data from comparable ITF events shows that matches involving unseeded or lower-ranked competitors often trade at extreme probabilities early, then shift materially as tournament draws are confirmed and player fitness status becomes clearer. The absence of meaningful liquidity at 0% suggests the market may be illiquid rather than reflecting genuine consensus.
Key catalysts include official tournament draw confirmation, which typically occurs 5–7 days before competition begins, and any withdrawal announcements from either player due to injury or scheduling conflicts. Traders should monitor ITF rankings updates and recent match results from both players' spring schedules. The settlement window closes 2 June 2026, providing a narrow window for resolution; any match delay beyond 7 days from the scheduled date triggers a 50-50 resolution regardless of eventual outcome.
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: Gala Ivanovic 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.
$279 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.
