Market outcomes
| ITF Szentendre: Valentina Steiner vs Allegra Korpanec Davies | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Valentina Steiner faces Allegra Korpanec Davies in the ITF Women's tournament at Szentendre, Hungary, scheduled for 28 May 2026. The current order book on Polymarket reflects zero probability for a Steiner victory, suggesting either strong market conviction favouring Davies or minimal trading activity establishing price discovery. With the settlement window closing 4 June 2026, traders have roughly a week post-match for resolution.
ITF Women's events at this tier typically feature players ranked between 400–800 on the WTA scale, with outcomes heavily dependent on recent form and surface-specific performance. Steiner, an Austrian player, and Korpanec Davies, who competes under a dual nationality flag, have limited head-to-head history at professional levels. The 0% implied probability warrants scrutiny—such extreme readings often reflect sparse liquidity rather than certainty, particularly for lower-profile ITF matches where trading volume remains thin.
Key catalysts include official tournament draw confirmation and any player withdrawal announcements, which commonly occur in ITF events 48–72 hours before scheduled play. Surface conditions at the clay courts in Szentendre and weather forecasts closer to late May will influence match dynamics. Traders should monitor the Polymarket order book for any shift in liquidity; if either player withdraws or the match is postponed beyond seven days without completion, the market resolves to 50-50 regardless of current pricing.
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 Szentendre: Valentina Steiner vs Allegra Korpanec Davies" 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.
$315 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.
