The event is part of the ATP Masters Series on the men's tour and is a Premier Mandatory event on the women's tour. The event, held in March, is one of two tour events (beside Miami Masters) in which main draw play extends beyond 8 days. The women's main draw usually starts on Wednesday and the men's main draw starts on Monday. Both finals are held on Sunday of the following week. Both singles main draws include 96 players. The 32 seeded players get a bye to the second round.
The tournament is played on hard courts and is the best attended tennis tournament outside the four Grand Slam tournaments, with over 300,000 visitors during the event. It has the second largest stadium in the world.
The tournament is usually held in early March. However in 2020, it was cancelled due to the COVID-19 pandemic, and in 2021, it was on in October. Cameron Norrie from Great Britain and Paula Badosa from Spain are the most recent champions.
