I dont think Pride salaries have ever been confirmed. It was rumored Fedor made a mil a fight, but he denied it.

UFC, however, is a different story. Nevada's Athletic commission requires the UFC to make a fighter pay public. And let me tell you, they dont make shit. Thats why fighters have so many sponsors. Free Gear, Free supplements, etc. If you google "UFC Fighter pay", you'll find links to most of the recent ufc matches, with fighter pay, and usually their win bonus, too
