Description

Another set of tennis doubles faces off in the same tournament round, with the market outcome depending entirely on which team secures the win. The structure mirrors standard competitive play with defined contingency handling for disruptions.

Kalshi

The market resolves to Yes if the specified duo wins the professional tennis match in the 2026 ATP Chengdu Round Of 16 after a ball has been played. Should the match fail to occur due to injury, walkover, forfeiture, or other pre-play cancellations, the market resolves to a fair price. Postponements or delays keep the market open until the rescheduled match finishes within two weeks. Kalshi holds no official connection to the Governing League, and all trademarks remain property of their respective owners.
