Market outcomes
| ITF Monastir: Emma Mazzoni vs Natalia Sousa Salazar | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Emma Mazzoni, an Italian ITF competitor, faces Natalia Sousa Salazar in the ITF Women's tournament at Monastir, Tunisia, scheduled for 28 May 2026. The match represents a lower-tier professional fixture on the ITF circuit, where both players are building ranking points outside the WTA main tour. The 0% implied probability on Polymarket's order book reflects minimal trading activity rather than certainty of outcome; with negligible liquidity in the book, even small positions can skew the displayed probability toward extremes.
ITF women's matches at this level typically involve players ranked outside the WTA top 200, where form and recent match play carry substantial weight. Historical precedent suggests that when prediction markets show extreme probabilities (0% or 100%) on lower-tier tennis fixtures, the underlying cause is usually illiquidity rather than genuine consensus. Comparable ITF tournaments show that upsets occur regularly, particularly when one player has recent match experience and the other does not. Without substantial backing on either side of this market, the current probability should be read as a liquidity signal rather than an informed assessment.
Traders should monitor entry lists and withdrawal announcements through the ITF website through late May, as player withdrawals remain common at this level. Court conditions at Monastir, typically clay, may favour particular playing styles. Any news regarding injuries or late scratches in the days preceding 28 May could shift market activity materially, though the settlement window extends to 4 June to account for scheduling delays.
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: Emma Mazzoni vs Natalia Sousa Salazar" 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.
$322 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.
