Market outcomes
| ITF Monastir: Anastasia Sysoeva vs Karla Bartel | 0% YES | 100% NO |
| Completed Match | 0% YES | 100% NO |
Anastasia Sysoeva and Karla Bartel are scheduled to meet in the ITF Women's tournament at Monastir on 27 May 2026. The match is set for 4:30 AM ET, with settlement occurring by 3 June 2026. Currently, Polymarket's order book reflects zero probability for a Sysoeva victory, suggesting either strong conviction in a Bartel win or minimal trading activity establishing a floor price. ITF events at this tier typically draw limited liquidity, and opening probabilities often reflect incomplete information rather than efficient pricing.
Sysoeva, a Ukrainian player, and Bartel, a Canadian competitor, operate within the ITF circuit where form fluctuates considerably between tournaments. Historical ITF matchups at Monastir show variable seeding patterns and surface adaptation challenges. The 0% implied probability warrants scrutiny—such extreme readings often indicate thin order books rather than certainty. Comparable ITF women's matches rarely settle at absolute extremes unless one player withdraws or faces documented fitness concerns.
Key catalysts include official tournament draws, which typically confirm 48–72 hours before play, and any player withdrawal announcements. Weather disruptions at Monastir in late May are possible but not common. The seven-day delay clause creates settlement risk if either player contests a match abandonment. Traders should monitor ITF rankings updates and recent tournament results from both players in the weeks preceding the event, as these directly influence perceived match probability.
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: Anastasia Sysoeva vs Karla Bartel" 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.
$65 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.
