Market outcomes
| ITF Wichita: Eryn Cayetano vs Dana Guzman | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Eryn Cayetano and Dana Guzman are scheduled to meet in the ITF Women's circuit event at Wichita on 28 May 2026. The match forms part of the lower-tier professional tennis calendar, where both players compete for ranking points and prize money. The current Polymarket order book reflects a 0% implied probability for Cayetano, suggesting the market has priced in either strong conviction for Guzman or substantial uncertainty about match completion. Settlement occurs on 4 June 2026 at 15:00 UTC, allowing a seven-day window for the match to conclude.
ITF Women's matches at this level carry higher cancellation and withdrawal rates than WTA events, driven by player injury, travel logistics, and financial constraints. Historical precedent shows that when one player carries significantly longer odds in lower-tier ITF markets, it often reflects either seeding disparity, recent form data, or pre-match withdrawal signals rather than pure match-play probability. The 0% pricing here warrants scrutiny: it may indicate Guzman is seeded substantially higher, Cayetano has withdrawn, or the market has received information about player availability.
Traders should monitor ITF Wichita draw confirmations and entry lists through late May, as these typically confirm or contradict early market assumptions. Recent player social media activity, injury reports, and tour scheduling announcements will signal whether both competitors remain committed to the fixture. Any withdrawal or late scratches would trigger the 50-50 tie-break resolution, fundamentally altering the market's risk profile.
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 Wichita: Eryn Cayetano vs Dana Guzman" 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.
$6K 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.
