The Barbie film has hit the billion-dollar mark just 17 days after it was released, according to distributor Warner Bros.
The movie will finish the weekend with $1.03bn (£808m) in ticket sales at the global box office, it said in a statement on Sunday.
It means Greta Gerwig has become the first woman to reach the milestone as a solo director.
Warner Bros described it as a "watershed moment".
Jeff Goldstein, president of domestic distribution in the US, said: "No-one but Greta Gerwig could have brought this cross-generational icon and her world to life in such a funny, emotional and entertaining story... literally turning the entire world pink."
