The Nitto ATP Finals has a round-robin format, with eight players/teams divided into two groups of four. The eight seeds are determined by the ATP Rankings and ATP Doubles Team Rankings on the Monday after the last ATP World Tour tournament of the calendar year. All singles matches are the best of three tie-break sets, including the final. All doubles matches are two sets (no ad) and a Match Tie-break.
The top seeded players/team is placed in Group A and the second seeded player/team is placed in Group B. Players/teams seeded 3 and 4, 5 and 6, 7 and 8, are then drawn in pairs with the first drawn placed in Group A. Each player/team plays the three other players/teams in his group. The winner of each group (best overall record) is placed in separate semi-final brackets, with the top player/team in Group A playing the runner-up in Group B, and vice versa. If two or more players/teams are tied after the round robin matches, the ties are broken by the Tie-Break Procedure.
