Market outcomes
| ITF Tauste-Zaragoza: Guiomar Maristany Zuleta De Reales vs Elizabeth Mandlik | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Guiomar Maristany Zuleta De Reales and Elizabeth Mandlik are scheduled to compete in the ITF Women's tournament at Tauste-Zaragoza on 29 May 2026. The market currently reflects a 100% implied probability for Maristany Zuleta De Reales advancing, as shown across Polymarket's order book. This extreme pricing suggests either substantial confidence in the Spanish player's superiority or limited liquidity at the current quote, with no meaningful backing available for an Mandlik victory at any price level.
ITF Women's tournaments at this level typically feature significant variance in outcomes, particularly when comparing players ranked outside the WTA's top 200. Historical precedent from comparable ITF events shows that matches between players of similar developmental stages frequently produce upsets, with lower-seeded or unseeded competitors winning roughly 25–35% of the time depending on surface and draw positioning. The 100% probability assigned here warrants scrutiny against typical match-win distributions at this tier, suggesting either a substantial ranking or seeding advantage for Maristany Zuleta De Reales that isn't immediately apparent from standard databases.
Traders should monitor official ITF and tournament draw confirmations as the May 29 date approaches, including any late withdrawals or schedule changes that could affect match conditions. Surface conditions at clay courts in Spain, player injury reports, and final seeding announcements in early May will provide concrete data points to test whether current pricing reflects genuine form differentials or merely thin order-book depth. The settlement window closes 5 June 2026, allowing a seven-day buffer beyond the scheduled match date for completion.
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.
$9K 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.
