Market outcomes
| ITF Kursumlijska Banja: Klara Vaja vs Sara Cozma | 22% YES | 79% NO |
| Completed Match | 50% YES | 50% NO |
Klara Vaja and Sara Cozma are scheduled to compete in the ITF Women's circuit event at Kursumlijska Banja on 2 June 2026. The current order book on Polymarket prices Vaja's advancement at 22%, reflecting substantial backing for Cozma despite both players operating at the lower rungs of professional tennis. ITF tournaments at this tier typically feature significant volatility in match outcomes, with seeding and ranking differentials often proving less predictive than surface conditions and recent form.
Vaja, a Hungarian player, and Cozma, Romanian, have limited head-to-head history at this level. The 22% probability suggests the market perceives a meaningful gap in capability or current trajectory, though ITF Women's draws frequently contain upsets driven by injury, mental resilience, or tactical adjustment rather than raw ranking points. Recent ITF results show that lower-ranked players frequently exploit unfamiliar opponents and court conditions; the Kursumlijska Banja clay surface favours certain playing styles that may not align with pre-match expectations.
Traders should monitor entry lists and any withdrawal announcements through the ITF website in the week preceding 2 June, as late scratches are common at this level. Weather conditions on the day—clay courts are particularly sensitive to moisture and temperature—could materially affect match dynamics. The settlement window extends to 9 June, allowing seven days for completion; delays beyond this trigger a 50-50 resolution, introducing tail risk for positions held through the scheduled date.
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.

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.
$0 in lifetime turnover and $849 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.
