Market outcomes
| ITF Wichita: Anita Sahdiieva vs Reese Brantmeier | 0% YES | 100% NO |
| Completed Match | 100% YES | 0% NO |
Anita Sahdiieva and Reese Brantmeier are scheduled to compete in the ITF Women's tournament in Wichita on 27 May 2026. The current order book on Polymarket shows zero probability assigned to Sahdiieva advancing, suggesting either minimal trading activity or strong conviction backing Brantmeier. With settlement occurring on 3 June, traders have roughly a week post-match for results to be confirmed and reported through official ITF channels.
ITF Women's matches at this level typically feature players ranked outside the WTA top 200, where form variance and surface-specific strengths create meaningful uncertainty. Comparable lower-tier ITF tournaments show that seeding and recent results matter substantially, yet upsets occur frequently enough that zero-probability markets often reflect illiquidity rather than certainty. The absence of trading volume here suggests the market may not have attracted sufficient participation to establish a genuine consensus line.
Key variables for traders include official ITF seeding announcements, recent head-to-head records if available, and surface conditions at the Wichita venue. Any withdrawal or injury announcements in the days before 27 May would trigger the 50-50 tie-break clause if the match does not proceed. Court scheduling changes or weather delays extending beyond 7 days would similarly force resolution to a split. Confirmation of both players' participation and fitness status closer to the event date will be essential for pricing adjustment.
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: Anita Sahdiieva vs Reese Brantmeier" 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.
$586 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.
