The Last Jedi is coming in second to The Force Awakens.
This isn’t a surprise either. The Force Awakens was the movie no one knew we’d ever see. So there was a broader set of interest for it. Rogue One proved that a spin-off film could be highly successful grossing over $1 Billion in worldwide box office. The Last Jedi is tracking between those two films, but closer to the sales of Rogue One.
I’m still waiting to see if my gross box office prediction of $1.7 Billion holds up. It has already passed $1 Billion before Dec 31, 2017.
