Description

This market tracks the outcome of a professional tennis doubles match featuring two pairs of players competing in an upcoming tournament. The resolution depends solely on which pair emerges victorious after the match begins. If the contest does not start due to cancellations or injuries, the market adjusts fairly rather than settling on a win for either side.

Kalshi

The market resolves based on the result of the Klepac / Ninomiya vs Tjen / Zhang professional tennis doubles match in the 2026 WTA Washington Semifinal, contingent upon play commencing. If Klepac / Ninomiya win after any ball is struck, their market settles to Yes. Conversely, a win by Tjen / Zhang after play begins resolves their market to Yes. Should the match fail to start—due to injury, walkover, forfeiture, or other cancellation—the market determines a fair price instead of defaulting to either outcome. Any postponement keeps the market open until the rescheduled match concludes, with settlement occurring within two weeks of the final result. The market operates independently of official league affiliations, and all branding remains property of their respective owners.
