Market outcomes
| ITF Tauste-Zaragoza: Luisina Giovannini vs Delia Gaillard | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Luisina Giovannini, an Argentine tennis player, faces Delia Gaillard in a Women's ITF tournament match scheduled for 27 May 2026 in Tauste-Zaragoza, Spain. The current order book on Polymarket reflects a 100% implied probability for Giovannini's advancement, suggesting the market has priced in either substantial confidence in her form or limited liquidity depth at current levels. With settlement closing 3 June 2026, traders have approximately one week post-match for resolution confirmation.
ITF Women's circuit matches at this level typically feature significant variance in outcomes, particularly when comparing players ranked outside the top 200. Historical precedent from comparable ITF tournaments shows that overwhelming probabilities (above 95%) often reflect either a substantial ranking differential, recent head-to-head results favouring one player, or shallow order book conditions rather than certainty. Giovannini's career ranking and recent tournament results would determine whether this pricing reflects genuine competitive advantage or market inefficiency.
Key catalysts include official tournament draws confirmation, any last-minute withdrawals or scheduling changes, and weather conditions in Zaragoza during late May. Traders should monitor ITF's official website and the WTA rankings database for any updates on player form or injury status in the fortnight preceding the match. The 50-50 resolution clause for matches delayed beyond seven days or abandoned mid-play introduces additional settlement risk that the current probability may not fully account for.
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: Luisina Giovannini vs Delia Gaillard" are the same as any other PolyGram sporting 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.
$66 in lifetime turnover and $0 of resting liquidity puts this market in the below the median by volume for sports 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.
