How much money did Justice League lose?

Probably not that much.

This image got around a lot because it came from Forbes. They estimated that it was going to lose $50 million but that was based on the expectation that it was going to gross $635 million.



Well it did better than expected and finished with $657 million so it may not have lost a significant amount.

And seeing as Wonder Woman made $300 million profit, DC still came out of the year with a significant profit.
