Market outcomes
| ITF Wichita: Sahaja Yamalapalli vs Ekaterina Khayrutdinova | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Sahaja Yamalapalli faces Ekaterina Khayrutdinova in the ITF Women's tournament at Wichita, scheduled for 30 May 2026. The match is currently priced at 100% implied probability on Polymarket's order book, indicating either extremely thin liquidity or a technical settlement condition rather than genuine market consensus on the outcome. With the settlement window closing on 6 June, traders have a narrow window to assess the matchup before resolution criteria become binding.
ITF Women's events at this tier typically feature players ranked outside the WTA top 200, making historical precedent difficult to establish without access to recent head-to-head records or tour-level performance data. Yamalapalli and Khayrutdinova's relative rankings, recent match results, and surface-specific form would normally anchor probability estimates. The 100% price suggests the market may be reflecting settlement mechanics rather than genuine confidence in either player's advancement—particularly given the tie-resolution clause and the seven-day grace period for delayed matches.
Key variables for traders include confirmation of the match proceeding as scheduled, any last-minute withdrawals or injury announcements, and weather conditions in Wichita during late May. ITF scheduling changes and player availability shifts are common at this level. The settlement window's early closure relative to typical tournament timelines means traders should monitor official ITF communications and venue updates closely. Any delay beyond 7 June without a completed match would trigger the 50-50 resolution, fundamentally altering the 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: Sahaja Yamalapalli vs Ekaterina Khayrutdinova" 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.
$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.
