Guardians of the Galaxy Vol. 2 added an estimated $9.733 million USD domestically and has now collected #355.47 million in North America across its four weeks of release. Overseas, it added another $4.4 million, bringing its international total to $461.1 million USD.
Though it likely won't cross the $1 billion mark that some bullish analysts estimated before the film was released, the film's current total is still good enough to make Vol. 2 the 5th highest grossing MCU film to date. However, it won't catch the 4th place film, Captain America: Civil War, which grossed $1.15 billion worldwide.
