But the mutants don't exist in the MCU, and they never will, as long as Fox holds the rights to the word 'mutant' and anything mutant-related from Marvel Comics. And for Fox to lose those rights they must not make any new X-Men movie for nine years. That was one of the terms of their contract with Marvel. When Fox didn't make another Daredevil film after 2003, the rights to that character reverted to Marvel Studios on October 10th, 2012. So, if we assume that the upcoming film Logan really is the last in the X-Men series and that Fox won't try to reboot that franchise, Marvel would still have to wait until 2026 to introduce the mutants to the MCU.
