Kapadia next played arms dealer Priya Singh in Christopher Nolan's spy thriller "Tenet". Her screen test for the role was shot in 2019 by Adajania before filming for "Angrezi Medium" began, followed by an audition for Nolan in Mumbai. Impressed with her charisma and poise, Nolan, believing she embodied his vision of the character, cast Kapadia in the part. The film opened amid the pandemic to a worldwide audience and, having grossed $362million worldwide, became the fourth-highest grossing film of 2020. Critics reacted positively to her performance; Richard Roeper of "Chicago Sun-Times" wrote Kapadia "quietly steals every scene she's in" and Guy Lodge of "Variety" said she had given the film's "wiliest performance". Having admitted to being a reluctant actor for years, Kapadia credited "Tenet" with restoring her passion for film acting.
