Market outcomes
| ITF Tauste-Zaragoza: Tessa Johanna Brockmann vs Elizabeth Mandlik | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Tessa Johanna Brockmann faces Elizabeth Mandlik in an ITF Women's event at Tauste-Zaragoza scheduled for 27 May 2026. The match is set for 4:00 AM ET, a notably early start time that may affect player availability and scheduling reliability. The current order book on Polymarket shows zero implied probability for a Brockmann victory, suggesting either strong market conviction favouring Mandlik or insufficient liquidity to establish a meaningful two-sided market at present.
ITF circuit matches at this tier typically feature significant variance in player form and preparation, particularly given the early morning scheduling. Mandlik, a former NCAA player with professional experience, has competed across multiple ITF and WTA qualifying events. Brockmann's recent activity and ranking trajectory would be relevant benchmarks for assessing relative form, though ITF results can be volatile depending on draw strength and player commitment to lower-tier events. Historical precedent suggests markets on ITF matches often reflect limited information until closer to event dates, when player withdrawals or late confirmations become apparent.
Traders should monitor official ITF and tournament communications for any scheduling changes, player withdrawals, or injury announcements in the weeks preceding 27 May. The seven-day resolution window creates a meaningful risk parameter—delays beyond that trigger a 50-50 settlement regardless of eventual outcome. Early morning scheduling increases the likelihood of last-minute changes. Any liquidity injection into the order book would likely reflect updated information on player participation or recent form indicators from competing events.
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: Tessa Johanna Brockmann vs Elizabeth Mandlik" 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.
$1K 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.
