Market outcomes
| ITF Monastir: Jonas Eriksson Ziverts vs Izan Almazan Valiente | 56% YES | 44% NO |
| Completed Match | 50% YES | 51% NO |
Jonas Eriksson Ziverts, a Swedish ITF competitor, faces Izan Almazan Valiente in a Men's ITF tournament match scheduled for 14 May 2026 at the Monastir venue in Tunisia. The current order book on Polymarket reflects a 50-50 split, indicating traders view both players as evenly matched prospects for advancing through this fixture.
Both players operate within the ITF Men's circuit, where ranking volatility and match outcomes depend heavily on recent form, surface adaptation, and head-to-head records. Eriksson Ziverts competes primarily on the European ITF circuit, whilst Almazan Valiente has competed across multiple regions. Historical ITF matchups at Monastir show variable outcomes; clay-court performance and acclimatisation to North African conditions have proven decisive factors in prior tournaments. The 50-50 probability suggests the market has limited distinguishing data between the two competitors at this specific venue, or that recent form indicators are balanced.
Traders should monitor ITF rankings updates and any withdrawal announcements through the official ITF website in the days preceding 14 May. Weather conditions in Monastir during that period could favour one player's style over another, particularly if wind patterns affect clay-court play. The settlement window extends to 21 May, allowing a seven-day buffer for match delays; however, any cancellation or rescheduling beyond that window would trigger a 50-50 resolution. Recent ITF tournament reports from North African venues indicate fixture reliability remains high, reducing the probability of no-play scenarios.
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 Monastir: Jonas Eriksson Ziverts vs Izan Almazan Valiente" 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.
$0 in lifetime turnover and $274 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.
