Market outcomes
| ITF Tauste-Zaragoza: Jennifer Ruggeri vs Guiomar Maristany Zuleta De Reales | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Jennifer Ruggeri and Guiomar Maristany Zuleta De Reales are scheduled to compete in the ITF Women's tournament at Tauste-Zaragoza on 30 May 2026. The match is set for 6:00 AM ET, with settlement occurring by 6 June 2026. Polymarket's order book currently reflects a 100% implied probability for resolution, suggesting either overwhelming confidence in match completion or minimal trading activity at present price levels.
ITF Women's circuit matches at this tier typically proceed as scheduled unless weather or injury intervenes. Ruggeri, an Italian player, and Maristany Zuleta De Reales, a Venezuelan competitor, both compete regularly on the ITF circuit where completion rates remain high. Historical precedent from comparable ITF tournaments shows cancellations occur in fewer than 5% of scheduled matches, with delays beyond seven days rarer still. The current probability reflects baseline expectations for a standard ITF event rather than event-specific intelligence.
Traders should monitor tournament draw confirmations and player injury reports in the week preceding the match. Spanish weather patterns in late May typically favour play, though occasional rain disruptions occur in the region. Any withdrawal announcements from either player would immediately alter market dynamics. The settlement window's seven-day grace period provides buffer against minor scheduling delays, though traders should track official ITF communications and venue updates as the event date approaches.
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: Jennifer Ruggeri vs Guiomar Maristany Zuleta De Reales" 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.
$223 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.

Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
