I really don't know why I keep seeing it everywhere that the match was fixed (Like seriously?) I've heard more than ten people saying that match looks like a fixed one

How could a match be fixed for Anthony Joshua to lose when he's going to lose 3 vital belts which will reduce his market value.

Anthony Joshua currently remains one of the most marketable boxers in the world and his defeat cost him some of his titles. Saying he intentionally didn't want to win the match because some people have promised to give him triple of what he's going to take home if he won get makes no sense at all.

Looking at the match, Joshua was rather not brutal enough like Ruiz. He was too relaxed, too confident that he would win and he probably underrated Ruiz!

What do you think about this match? Do you think it looks suspicious as a fixed match?
