Market outcomes
| ITF Tauste-Zaragoza: Jana Otzipka vs Eva Vedder | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Jana Otzipka faces Eva Vedder in an ITF Women's tournament match scheduled for 27 May 2026 at the Tauste-Zaragoza venue. The current order book on Polymarket shows zero probability assigned to Otzipka's victory, reflecting either minimal trading activity, strong backing for Vedder, or insufficient liquidity to establish a meaningful spread. Settlement occurs on 3 June 2026, allowing a week-long window for the match to conclude and be reported through official ITF channels.
ITF Women's circuit matches at this tier typically feature players ranked outside the WTA top 200, where historical head-to-head records are sparse and recent form becomes the primary differentiator. The 0% implied probability suggests either Vedder has substantially superior recent results or ranking, or the market has simply not attracted sufficient trader participation to price Otzipka's chances. Without established comparative data between these opponents, traders should examine recent ITF tournament results, current rankings, and surface-specific records—particularly on clay, given Tauste-Zaragoza's typical court composition.
Key catalysts include official confirmation of both players' participation closer to the event date, any withdrawals or injury announcements, and weather disruptions that could delay proceedings beyond the settlement window. ITF tournament schedules occasionally shift due to draw adjustments or player retirements. Traders should monitor the WTA and ITF official sites for roster updates and any news regarding either player's fitness or competing commitments during late May 2026.
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 Tauste-Zaragoza: Jana Otzipka vs Eva Vedder" 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.
$660 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.
