Market outcomes
| Completed Match | 0% YES | 100% NO |
| ITF Kayseri: Stefan Cooper vs Cagan Efe Tufekci | 100% YES | 0% NO |
Stefan Cooper and Cagan Efe Tufekci are scheduled to compete in the ITF Men's Kayseri tournament on 2 June 2026. The match represents a lower-tier professional tennis fixture on the ITF circuit, where both players compete for ranking points and prize money. The current 0% implied probability on Polymarket's order book reflects either an absence of liquidity at meaningful price levels or a consensus view that one player holds overwhelming advantage. Given the settlement window closes 7 June 2026, traders have limited time to adjust positions once the match concludes or is officially postponed.
ITF Men's events at this tier typically feature significant volatility in match outcomes compared to ATP-level fixtures. Historical data on comparable ITF Kayseri tournaments shows that seeding and recent form matter considerably, though upsets remain common when players face unfamiliar opponents or encounter surface-specific challenges. The 0% probability suggests either Cooper or Tufekci is heavily favoured based on current rankings, recent results, or withdrawal risk—though without explicit odds data visible, the true market sentiment remains opaque.
Traders should monitor official ITF and tournament communications for withdrawal announcements, which would trigger the 50-50 resolution clause. Weather conditions in Kayseri during early June could affect scheduling. Recent player injury reports or late withdrawals from preceding tournaments would signal match viability. The tight settlement window means any delay beyond 7 days without completion automatically resolves to 50-50, creating a specific risk vector independent of on-court performance.
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 market has been open for under a month — fresh enough that information asymmetry remains a real factor.
