The Lionsgate movie is currently sitting at $399.5m after last night's takings in total at the US and Canadian box office.
Its global box office takings are almost $650 million (£420m).
The sci-fi movie will follow The Avengers as the second film to pass the milestone at the US box office this year.
If another upcoming movie - such as the highly-anticipated The Dark Knight Rises - also passes the barrier, it will be the first time that three films have taken in over $400m within a year in North America.
The Avengers passed global takings of $1 billion (£623 million) in May.
The Hunger Games dominated the MTV Movie Awards last weekend, including prizes for its stars Jennifer Lawrence and Josh Hutcherson.
