Market outcomes
| ITF Kursumlijska Banja: Teodora Kostovic vs Julie Struplova | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Teodora Kostovic faces Julie Struplova in the ITF Women's circuit event at Kursumlijska Banja, scheduled for 28 May 2026. The match is a first-round encounter on the lower-tier professional tennis circuit, where both players compete for ranking points and prize money. The current order book on Polymarket reflects a 100% implied probability for Kostovic's advancement, suggesting either substantial backing for the Serbian player or minimal liquidity driving the extreme pricing.
ITF Women's matches at this tier typically feature significant variance in outcomes, with ranking disparities often less predictive than at WTA level. Kostovic, competing in her domestic region, may hold a home advantage factor that traders are pricing in heavily. Comparable ITF events show that overwhelming probabilities (above 95%) frequently stem from thin order books rather than genuine certainty about match outcomes. The settlement window closes on 4 June 2026, providing a seven-day buffer beyond the scheduled date for match completion, though delays or cancellations remain standard operational risks on the ITF circuit.
Traders should monitor official ITF tournament updates for any schedule changes, player withdrawals, or surface conditions that might affect match viability. Recent ITF scheduling data indicates that Eastern European events occasionally face logistical delays. The extreme probability pricing warrants caution—a modest counter-position could offer value if Struplova's recent form or head-to-head record suggests competitive balance. Confirmation of both players' participation and fitness status closer to the event date will be critical for position management.
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 Julie Struplova" 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.
$8K 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.
