Market outcomes
| ITF Tauste-Zaragoza: Andrea Lazaro Garcia vs Tyra Caterina Grant | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Andrea Lazaro Garcia, a Spanish ITF competitor, faces fellow player Tyra Caterina Grant in a Women's ITF tournament match scheduled for 28 May 2026 at Tauste-Zaragoza. The current order book on Polymarket reflects a 100% implied probability for Garcia's advancement, suggesting the market has priced in either strong historical precedent or material information about Grant's participation status. This extreme probability warrants scrutiny, as ITF-level matches frequently produce unexpected outcomes and withdrawal announcements can shift pricing substantially in the final days before play.
Garcia competes regularly on the ITF Women's circuit, where her performance record against comparable opponents provides the baseline for assessing match likelihood. Grant's recent tournament activity and ranking trajectory would typically anchor expectations, though ITF draws often feature players with limited head-to-head history. The 100% reading suggests either a significant disparity in current form or preliminary indications that Grant may not compete, though such certainty at this distance from the settlement window (7 June 2026) is unusual absent confirmed withdrawal.
Traders should monitor ITF tournament draw confirmations and any player withdrawal announcements through late May, as these represent the primary catalysts affecting resolution. Weather disruptions at Spanish venues occasionally delay matches beyond the seven-day threshold, which would trigger a 50-50 resolution. The settlement window closes 4 June, creating a narrow window for late developments to affect pricing before the match date itself.
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.

$4K 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.
