In 2020, no female drivers were on the official entry list. It marked the first time since 1999 that there would not be a female driver in the starting lineup. The 2020 race also marked the first time since 1991 that not a single female driver was entered. Pippa Mann, who raced her seventh 500 in 2019, did not enter the 2020 race; because of the COVID-19 pandemic, she was unable to secure corporate sponsorship, so lacked the funds needed to sustain an IndyCar season.
