Jurassic World may have absolutely dwarfed Fallen Kingdom on a domestic-level, grossing 652 million in-comparison to Fallen Kingdom's current total of 333 million (however, it does appear Jurassic World 2's on-pace to reach 400 million domestically with a little luck), but Fallen Kingdom has picked up a lot of slack elsewhere. Propped up by a run in China that has amassed nearly 250 million total, Fallen Kingdom has made over 700 million outside the United States and Canada (in-comparison to the billion made from Jurassic World).
Although Jurassic World 2 has dwindled in most its territories, where it stands, it has the potential to finish it's run with a total of more than 1.2 billion. Universal has more than enough cause for celebration.
