Kalshi
This market focuses on the outcome of a specific tennis match between Alexander Zverev and Botic Van de Zandschulp at the 2026 US Open Men Singles Quarterfinal. It tracks who will win the match after play has begun, reflecting the competitive performance of both athletes in a high-stakes tournament setting.
The market resolves based on the winner of the Zverev vs Van de Zandschulp professional tennis match in the 2026 US Open Men Singles Quarterfinal, provided that at least one ball has been played. If the match does not occur before any ball is played—due to injury, walkover, forfeiture, or other cancellation—the market resolves to a fair price. Postponements or delays do not close the market; it remains open and settles after the rescheduled match concludes, with a two-week window for final resolution. Kalshi explicitly states it is not affiliated with the governing league, and all trademarks remain property of their respective owners.
