There will be fights for two championship belts among the many current and previous champions on the 300th pay-per-view show of the UFC, which is being celebrated.

Champion after champion appears at UFC 300.
The 300th pay-per-view card of the Ultimate Fighting Championship features combatants that serve as a reminder to fans of the brutal and frequently bizarre reality of mixed martial arts.

Twelve fighters in the 13 bouts on the UFC 300 card have held a UFC title at some point in their careers. This is a great way to promote the pay-per-view, which can be purchased in the US for $79.99 with an ESPN+ subscription, and it also serves as a timely reminder of how difficult it is to win a title and capitalize on the fame that comes with it.

The current light heavyweight champion, Alex Pereira, rose to prominence in a bigger class by positioning himself as a counterbalance to Israel Adesanya, one of the greatest names in the sport. After suffering two defeats in 2021, Zhang Weili had to bounce back to become the most well-known fighter in the sport from China. Now, Yan Xiaonan is vying for Zhang Weili's title and domestic bragging rights.

By developing a reputation for action-packed striking (and very little defense), Justin Gaethje and Max Holloway became fits for the BMF belt, the adorably (and profanely) named informal strap that appears to be just an excuse to offer fan favorites five rounds to entertain instead of three.

Even the first bout on the event (not the pay-per-view, the earliest preliminary card) has Deiveson Figueiredo, the former flyweight champion, moving up to bantamweight to challenge Cody Garbrandt, the former bantamweight champion who has been attempting for years to restart his career.
