The Saturday day session on August 15 drew 17,441 fans at the 2026 Cincinnati Open.
That attendance figure set a new day-session record for the tournament. It refers specifically to the daytime session, not the entire tournament or every session held during the event.
The 2026 Cincinnati Open also reported a night-session record of 13,533 fans on Thursday, August 13. Separating day and night sessions matters because attendance records can use different counting periods.
The event was held at the Lindner Family Tennis Center in Mason, Ohio. Its expanded schedule and strong American singles presence helped attract large crowds during the tournament’s run-up to the US Open.
