UFC superstars Dustin "The Diamond" Poirier and Justin Gaethje have made their names not just with brutal knockouts and jaw-dropping battles but with personalities outside the octagon. As both fighters continue to reel in victories and cash, fans are left wondering: how do their bank accounts stack up?

Dustin “The Diamond” Poirier is a veteran in the UFC’s lightweight division. He’s become one of the most recognized faces in the UFC world with over a decade of fights in the octagon. His iconic fights against UFC stars Conor McGregor and Khabib Nurmagomedov have solidified him as a massive star, both inside and outside the arena.
Poirier's net worth is estimated to be $10 million in 2025. Poirier has smartly distributed his wealth, raking in major endorsement deals from brands like Venum and various philanthropic efforts through his “The Good Fight Foundation,” which aims to uplift underprivileged communities. Add in that memorable knockout of McGregor at UFC 264, and you have a fighter who knows how to generate not just buzz, but big bucks.


Justin Gaethje is a fighter whose style and "fight-or-die" attitude have earned him a massive fan following. Known for his never-back-down approach, Gaethje has become a UFC fan-favorite, earning countless “Fight of the Night” bonuses. By 2025, Gaethje’s net worth sits at about $6 million, giving him a slight edge over Poirier.
While his road to the top hasn’t been as long or as decorated with titles, Gaethje’s reputation for delivering on-the-edge-of-your-seat action has made him an endorsement magnet. Partnerships with brands like Celebrity Sweat and PrizePicks, plus lucrative deals with lifestyle companies, have significantly padded his wallet.
Poirier may be having a slight lead over Gaethje, the difference isn’t much considering both their evaluations. Both fighters are on their way to rise with their performances and expanding business empires. The truth is, Poirier and Gaethje are still in their prime, and their financial fortunes are only going to grow as they chase more titles, more endorsements, and, of course, more fights.
