Another professional tennis match in the 2026 ATP Cincinnati Round Of 64 will determine the winner between two competitors, with the result based exclusively on the victorious player after play commences.
Markets resolve to Yes only if the specified player wins the match after at least one ball has been played. Should the match fail to occur before play begins—due to injury, walkover, forfeiture, or cancellation—the market resolves to a fair price. Any postponement or delay keeps the market open and closes after the rescheduled match finishes within two weeks. Kalshi emphasizes no official connection with the governing league, and all trademarks belong to their respective owners.
