1. Conor vs. Nate UFC 196 (2nd Round)
The two most profitable fights in the history of mixed martial arts were both fought between Conor McGregor and Nate Diaz. Based on PPV purchases, UFC 196 was the most successful PPV ever at the time, and that record would only be broken by the rematch at UFC 202.
This fight was sold based on Conor’s hype, Nate’s reputation, and an insane pre-fight press conference. UFC 202, the highest grossing PPV of all time, was sold based mainly on what happened in this fight here.
When he tapped it seemed like it was the end of the Conor show. Only Conor did the one thing he could do to recapture what he lost; he took the exact same fight at the same weight class and won. Now the Conor show is rolling on to make even more money fighting Floyd Mayweather.
