Market outcomes
| ITF Monastir: Masha Lazarenko vs Anastasia Bertacchi | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Masha Lazarenko and Anastasia Bertacchi are scheduled to compete in the ITF Women's tournament at Monastir on 30 May 2026, with the match originally set for 05:15 ET. The current order book on Polymarket reflects a 0% implied probability for Lazarenko's advancement, suggesting the market has priced in either a strong expectation of Bertacchi's victory or significant uncertainty around match execution. With settlement occurring just over a week after the scheduled date, the market allows for a seven-day window before defaulting to 50-50 resolution in case of cancellation or delay.
ITF Women's events at this tier typically feature players ranked between 300 and 800 globally, where match outcomes depend heavily on recent form, surface adaptation, and head-to-head records. Lazarenko's current ranking and recent tournament results would normally establish a baseline for probability assessment, but the 0% reading suggests either limited liquidity in the order book or market participants holding strong conviction about Bertacchi's superiority on clay courts, which Monastir features. Historical ITF Monastir tournaments have seen seeding disruptions and upsets, particularly when lower-ranked players face unfamiliar opponents.
Traders should monitor official ITF and WTA tour announcements for any withdrawal confirmations, injury updates, or schedule changes in the week preceding 30 May. Weather conditions in Tunisia during late May could affect court playability, whilst any late-stage ranking shifts for either player might signal form changes worth tracking. The extremely tight settlement window means match delays beyond 7 June would trigger the 50-50 resolution clause, introducing tail risk for positions held through that date.
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.

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.
$82 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.
