Market outcomes
| ITF Gimcheon: Sanhui Shin vs Kazuma Kawachi | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Sanhui Shin, a South Korean ITF competitor, faces Japan's Kazuma Kawachi in the men's draw at the ITF Gimcheon tournament, scheduled for 26 May 2026. The match is set for 10:00 PM ET, with the settlement window closing on 3 June 2026. The current order book on Polymarket reflects a 100% implied probability for resolution, suggesting traders are pricing near-certainty that the match will occur and produce a definitive winner within the settlement parameters.
ITF Men's circuit matches at this level typically proceed as scheduled unless weather or player injury intervenes. Both Shin and Kawachi compete regularly on the ITF circuit, where completion rates remain high. Historical precedent from similar ITF tournaments shows that matches rarely extend beyond the seven-day grace period outlined in the resolution criteria, and walkovers or retirements—which would trigger the 50-50 tie-break clause—occur in roughly 3–5% of fixtures at this tier. The current 100% probability reflects confidence that neither cancellation nor extended delay will occur.
Traders should monitor the ITF official schedule for any weather alerts or venue changes in the days preceding 26 May. Player injury announcements or withdrawal notices from either competitor would be the primary catalyst to shift the market. The Gimcheon venue has a reliable indoor facility, reducing weather-related cancellation risk. Settlement hinges on a completed match with a clear winner; any disruption lasting beyond 2 June would force the 50-50 resolution clause into play.
