DAZN is a bigger company than the owners of UFC but less experienced and more focused on sports on a whole as their endgame rather than just boxing. Neither company actually uses much of their own money anyway it's mostly borrowed and DAZN are the one's who have to make the moves whereas Endeavor are relatively in a safe spot. It's in DAZN's interest to get more rights to different sports than to just remain with boxing. Endeavor are in debt (more debt than DAZN) but are relatively in a safe zone financially. It wouldn't surprise me if UFC gets sold off again within the next decade. UFC and boxing don't really make much money in comparison to the Premier League or NFL.
