Description

This market focuses on the outcome of a professional tennis match between Manish Sureshkumar and Hiromasa Koyama scheduled for the 2026 M25 Taipei Round of 16. It tracks who wins the match, provided the match actually begins. The market accounts for various scenarios where the match might not proceed as planned, such as injuries or cancellations before play starts.

Kalshi

The market resolves based on the winner of the Sureshkumar vs Koyama professional tennis match in the 2026 M25 Taipei Round of 16, contingent upon the match actually commencing — indicated by a ball being played. If the match does not occur before any play due to injury, walkover, forfeiture, or other cancellation, all positions resolve at $0.50. If a player withdraws or forfeits after the match has started, that player’s market resolves to No. Postponements or delays do not close the market; it remains open until the rescheduled match concludes, with a resolution window of two weeks after the match finishes. The market is independent of any official league affiliations, and all trademarks remain property of their respective owners.
