Market outcomes
| ITF Tauste-Zaragoza: Guiomar Maristany Zuleta De Reales vs Anastasia Tikhonova | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Guiomar Maristany Zuleta De Reales, a Spanish ITF competitor, faces Russian player Anastasia Tikhonova in the ITF Women's tournament at Tauste-Zaragoza on 27 May 2026. The match is scheduled for 4:00 AM ET, with settlement occurring by 3 June 2026. Currently, Polymarket's order book reflects a 100% implied probability for Maristany's advancement, suggesting the market has priced in either substantial confidence in her victory or minimal liquidity at alternative price levels.
ITF Women's circuit matches at this level typically feature significant variance in outcomes, particularly when involving players ranked outside the WTA top 200. Historical precedent from comparable ITF tournaments shows that matches between players of similar developmental stage frequently resolve contrary to extreme probability assessments, especially when one competitor holds home-court advantage. Maristany's Spanish nationality and the tournament's location in Zaragoza may factor into the current pricing, though this alone rarely justifies 100% certainty in professional tennis.
Traders should monitor official ITF and tournament announcements regarding player withdrawals, injuries, or scheduling changes through late May. The early morning ET start time warrants attention to any weather disruptions or venue complications that could delay proceedings beyond the seven-day grace period specified in settlement terms. Recent tournament cancellations and rescheduling across European ITF events in spring 2026 suggest heightened operational risk, making the absence of liquidity at alternative probabilities potentially significant 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 Tauste-Zaragoza: Guiomar Maristany Zuleta De Reales vs Anastasia Tikhonova" 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.
$312 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.
