Which fighter won the main event of UFC 300?

Alex Pereira won the main event of UFC 300.

Pereira defended the UFC Light Heavyweight Championship against former champion Jamahal Hill in the headline bout at T-Mobile Arena in Las Vegas on April 13, 2024. He stopped Hill by first-round knockout after landing a powerful left hook and follow-up strikes.

The victory was a major moment on one of the UFC’s most heavily promoted anniversary cards. Pereira had won the light heavyweight title from Jiří Procházka at UFC 295 after previously holding the UFC Middleweight Championship.

UFC 300 is sometimes remembered for its full championship-heavy lineup rather than its headliner, so the main-event result can be overlooked. The card also included Zhang Weili’s strawweight title defense and Max Holloway’s dramatic knockout of Justin Gaethje.
