Description

This market focuses on predicting whether a tennis match between Karen Khachanov and Learner Tien at the 2026 US Open will extend beyond a certain number of sets. Bettors assess the competitive nature and potential for long rallies or breaks of serve that could lead to more sets being played. The outcome depends on how the match unfolds in terms of endurance, strategy, and momentum shifts between the two players.

Kalshi

The markets resolve to Yes if the specified number of sets (either over 3.5 or over 4.5) are played in the Karen Khachanov vs Learner Tien match during the 2026 US Open Men Singles Round of 16. If the match does not start due to injury, walkover, forfeiture, or cancellation, it resolves to a fair price. Postponements or delays keep the market open until the rescheduled match concludes, with resolution within two weeks. If a player retires, markets that can be settled based on completed play do so; others resolve to a Fair Market Price at the Exchange’s discretion. Kalshi is not affiliated with the governing league, and all trademarks remain property of their respective owners.
