Market outcomes
| Completed Match | 100% YES | 0% NO |
| ITF Kayseri: Stefan Cooper vs Rafael De Alba | 100% YES | 0% NO |
Stefan Cooper and Rafael De Alba are scheduled to compete in an ITF Men's tournament match in Kayseri on 27 May 2026. The current orderbook on Polymarket reflects 100% implied probability for resolution, indicating traders are pricing near-certainty that the match will be completed with a definitive winner rather than cancelled, delayed beyond the settlement window, or abandoned mid-play.
ITF Futures matches at this level typically proceed as scheduled unless significant logistical disruptions occur. Historical data on comparable ITF tournaments shows cancellation rates below 5% when matches are formally drawn into tournament brackets. The 100% probability reading suggests the market is treating the Kayseri event as operationally stable, with no current signals of venue issues, player withdrawals, or scheduling conflicts that would trigger the 50-50 tie-break resolution clause. Cooper and De Alba's respective rankings and recent form would normally drive directional pricing once the match begins, but the current orderbook is instead concentrated on binary completion risk.
Traders should monitor ITF Kayseri's official tournament schedule and any player injury announcements in the weeks preceding 27 May. Turkish weather conditions during late May are generally stable, reducing weather-related cancellation risk. The settlement window closes 3 June 2026, allowing a six-day buffer beyond the scheduled date for delayed matches to be completed. Any withdrawal by either player or venue complications would shift the orderbook sharply toward the 50-50 outcome.
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 Kayseri: Stefan Cooper vs Rafael De Alba" are the same as any other PolyGram sporting 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.
$703 in lifetime turnover and $0 of resting liquidity puts this market in the below the median by volume for sports 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.
