Market outcomes
| ITF Wichita: Maria Berlanga Bandera vs Dana Guzman | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Maria Berlanga Bandera and Dana Guzman are scheduled to compete in the ITF Women's tournament in Wichita on 27 May 2026. The match represents a lower-tier professional tennis fixture within the International Tennis Federation circuit, where both players typically compete for ranking points and prize money. The 0% implied probability currently reflected in Polymarket's order book suggests either minimal trading activity or a strong consensus that one player will not participate, though the settlement window extends to 3 June 2026, allowing seven days beyond the scheduled date for match completion.
ITF Women's matches at this level frequently feature players ranked outside the WTA's top 200, making historical precedent difficult to establish from major tournament data. However, ITF circuit reliability remains relatively high, with cancellations typically occurring only due to injury, visa complications, or severe weather. The current zero probability may reflect incomplete market information rather than fundamental certainty about the outcome.
Traders should monitor tournament draw confirmations and player social media for withdrawal announcements in the weeks preceding 27 May. ITF scheduling occasionally shifts due to facility availability or player scheduling conflicts. Any late withdrawal by either competitor would trigger the 50-50 resolution clause, fundamentally altering the match's predictability. Additionally, travel disruptions or injury reports emerging closer to the match date could affect participation likelihood, though such information typically surfaces within days rather than months of competition.
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.
$2K 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.
