The 550th UFC event is known variously at UFC Vegas 18, UFC Fight Night: Overeem vs. Volkov, UFC Fight Night 184, and UFC on ESPN+ 42. It will take place on Saturday, February 6, 2021, at the UFC APEX in Las Vegas, Nevada.

In addition to being paid a fixed amount to show and another, usually equal amount to win, each UFC event also awards four $50,000 Performance Bonuses. Usually, there is a Fight of the Night in which both fighters are given a performance bonus, and a performance bonus to the winner in two fights. 

For the record, “Performance Bonus” is for the moment that made you go “HOLY F@$%ING $#!@.”

The winners are shown below, in bold.

$50,000 Fight of the Night
Beneil Dariush defeated Diego Ferreira by Split Decision (28-29, 29-28, 29-28) 

$50,000 Performance Bonus 
Cory Sandhagen defeated Frankie Edgar by KO (Flying Knee, Round 1, 0:28)

$50,000 Performance Bonus
Alexander Volkov defeated Alistair Overeem by TKO (Strikes, Round 2, 2:06)

One of the primary differences between the UFC model and the boxing model is the depth of the card. Sometimes in MMA the greatest fight isn’t the main event, or close to it. However, at UFC 257, all bonuses went to the main card.

In addition, to the bonuses and purses, fighters earn:
•Reebok pay, based on tenure, for wearing the distinctive apparel during fight week and in the Octagon;
•Less commonly than in the past fighters get discretionary locker room bonuses of varying amounts, which, despite their name, actually come in the mail now;
•In some cases there is an LOA (Letter of Agreement) on the contract for additional income; and,
•The most elite fighters get points on the pay per view for PPV events, which this one was not.

The next league event is UFC 258: Usman vs. Burns on Saturday, February 13, 2021 at the UFC APEX in Las Vegas, Nevada.
