The six players headlining this event were Novak Djokovic, Rafael Nadal, Jannik Sinner, Carlos Alcaraz, Daniil Medvedev and Holger Rune.

Since this is not an ATP-sanctioned event, players do not earn any ranking points and the match results do not count towards official head-to-head tallies.

The official format is a single-elimination tournament, with two players getting byes directly to the semifinals: Rafael Nadal and Novak Djokovic.
