Market outcomes
| ITF Bastad: Isabel Skoog vs Vladlena Bokova | 90% YES | 11% NO |
| Completed Match | 50% YES | 51% NO |
Isabel Skoog and Vladlena Bokova are scheduled to compete in the ITF Women's tournament at Bastad on 14 May 2026. The match represents a lower-tier professional tennis fixture where both players are competing for ranking points and prize money on the International Tennis Federation circuit. The current order book on Polymarket reflects a 50-50 split, indicating traders see this as a genuine toss-up with no clear consensus on the likely winner.
Both players operate at the ITF level, where form, recent match history, and head-to-head records carry substantial weight in determining outcomes. Skoog, competing on home soil in Sweden, typically benefits from familiarity with local court conditions and reduced travel fatigue, factors that have historically shifted probabilities in favour of home players at smaller tournaments. Bokova's record against similarly-ranked opponents and her recent tournament results will determine whether the current even odds reflect genuine parity or represent mispricing relative to their underlying capabilities.
Traders should monitor official ITF tournament updates and player withdrawal announcements through early May, as injuries or scheduling conflicts frequently alter match-ups at this level. Weather conditions at Bastad—particularly wind and court surface moisture—can significantly favour one playing style over another. The settlement window extends to 21 May, allowing seven days beyond the scheduled date for completion, though delays beyond that trigger a 50-50 resolution. Any official confirmation of player fitness or late withdrawals in the week before competition will likely shift the current even odds.

$0 in lifetime turnover and $223 of resting liquidity puts this market in the below the median by volume for games 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.
