Fresh off UFC 326, Charles Oliveira is openly pushing for a showdown with Nate Diaz, a matchup that would pair the promotion’s new BMF titleholder with one of the most recognizable stars of the past decade. The Brazilian raised the idea this week while discussing future options as Diaz prepares for his May 16 return to MMA under the Most Valuable Promotions banner against Mike Perry.
From a UFC business standpoint, the appeal is obvious. Diaz remains one of the rare fighters whose name still cuts through to casual American fans, and Oliveira has built his own reputation as an action-first finisher who rarely appears in a boring fight. Put those two together, and the UFC would have a pay-per-view attraction that sells on personality as much as violence.
Oliveira said he and coach-manager Diego Lima have already talked through the possibility, framing it as both a sporting opportunity and a smart commercial play. He also made clear that he is not locked into one option, pointing to continued talk around a potential fight with Conor McGregor and emphasizing that any next move has to make sense for both him and the promotion.
The stakes go beyond spectacle. If Oliveira gets Diaz and wins, he strengthens his case as a crossover star who can headline major events without a traditional championship belt attached. If Diaz were to return and beat Oliveira, he would immediately re-enter the UFC conversation with leverage that few returning fighters ever have. That is why this matchup would matter well beyond the BMF label.
There is also a style angle American fans would instantly buy into. Oliveira is one of the UFC’s most aggressive submission threats, while Diaz has long built his brand on pressure, durability, and elite jiu-jitsu of his own. On paper, it is the kind of fight that feels chaotic in the best possible way.
Earlier this month at UFC 326, Oliveira captured the BMF title with a clear unanimous decision win over Max Holloway. Diaz, meanwhile, is set to face Perry on May 16, and whatever happens there will likely determine how realistic this potential blockbuster becomes.
