It was his eighth ATP 1000 title and 22nd ATP Tour title overall. Alcaraz was the youngest man to win in Cincinnati since Andy Murray in 2008. This was the first time since 2011 that the final ended in a retirement.
Térence Atmane was the first qualifier to reach the tournament's semifinals since Alexandr Dolgopolov in 2015.

Seeded players The following are the seeded players. Seedings are based on ATP rankings as of 28 July 2025. Rankings and points before are as of 4 August 2025.
Due to a change in schedule this year, ATP ranking points from the 2024 National Bank Open held in Montreal and the 2024 Cincinnati Open will both be dropped at the end of the 2025 Cincinnati Open.. Accordingly, the points defending column in the table below reflects the relevant player's results from both Cincinnati and Montreal 2024, with the Cincinnati result listed first. Unless otherwise specified, any points deducted from Montreal will be replaced with the player's next best result (listed second under points earned). Note that this method of calculating ranking points for this year's tournament is different from the WTA's method.
