Deadline reports that it needs to make $425 million globally to just break even, but that's assuming the $180 million budget is accurate... which it almost certainly is not.
I'm an quite confident we'll get a report in a couple of months, as we often do with big productions, about how the movie's real budget was in the $250+ million range. That $180 number has felt like spin to me, because no studio ever volunteers an accurate number up front.
