Market outcomes
| ITF Tauste-Zaragoza: Guiomar Maristany Zuleta De Reales vs Aran Teixido Garcia | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Guiomar Maristany Zuleta De Reales faces Aran Teixido Garcia in a women's ITF match at Tauste-Zaragoza, scheduled for 28 May 2026. The 100% implied probability on Polymarket's order book reflects either exceptionally strong conviction in Maristany's superiority or sparse liquidity in the market's early stages. ITF tournaments at this tier typically feature significant variance in player form and preparation levels, making such extreme probabilities unusual absent concrete information about player availability or injury status.
Comparable ITF women's matches show that favourites at this level rarely command such decisive odds unless one player has withdrawn or a significant ranking disparity exists. Maristany and Teixido Garcia's recent ITF records and head-to-head history would normally distribute probability more evenly, particularly given the lower seeding standards in ITF 25K events. The current pricing suggests either the market has priced in a withdrawal or injury announcement, or order book depth remains minimal with few counteroffers to test the consensus.
Traders should monitor official ITF and tournament communications through early June for any withdrawal notices, schedule changes, or injury updates. The settlement window closes 4 June 2026, allowing only days after the scheduled match date for resolution. Any delay beyond 7 days from 28 May triggers a no-contest resolution, creating a specific risk window. Confirmation of both players' participation and fitness status closer to the match date would be the primary catalyst for probability adjustment.
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 Aran Teixido Garcia" 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.
$2K 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.
