The Californian tournament will be re-scheduled for 2021.
March's Indian Wells Masters tennis has been postponed due to Covid-19 concerns.
Organisers say the decision was made after consultation with state and local health authorities and tournament owner Larry Ellison.
The ATP and WTA Tours are looking to confirm rescheduled dates for the tournament to go ahead in California later in the year.
