UFC BJJ 10 is set for Thursday, August 20, 2026, in Las Vegas, Nevada, with Andrew Tackett headlining a card built around two title bouts and the start of a tournament for the inaugural flyweight champion. The event streams live on YouTube at 8 p.m. ET, giving viewers a championship night that combines established names with a new title race.
Tackett enters looking for his seventh win and a fourth straight defense of his welterweight title against Jonnatas Gracie, who is 4-0 under the UFC BJJ / FPI banner. That matchup gives the main event a clean edge: one fighter trying to extend a run that already defines the division, the other arriving unbeaten in the same promotional framework and trying to break it.
The rest of the card keeps the same pressure. Rebeca Lima defends the UFC BJJ championship against Brianna Ste-Marie, a two-time no gi world champion, while the flyweight bracket begins with Adele Fornarino on one side and Cassia Moura on the other. Moura enters as the UFC BJJ bantamweight champion, and Fornarino’s choice is already carrying weight because she withdrew from the prestigious ADCC 2026 event for this title opportunity.
There is also a structural change that may matter as much as the matchups. UFC BJJ 10 will debut a smaller bowl with steeper walls, a shift that should make the action feel tighter and limit the room fighters usually use to reset at the edge. In practical terms, a smaller bowl means less flat space before the curve rises, so the wall comes into play sooner and more often; for grapplers, that can change how quickly a position stalls, turns, or gets restarted.
That is the quiet friction inside the night: the card is being sold as a showcase for elite title fights, but it is also pulling top athletes into a format that is changing under them. The roster includes William Tackett, Jalen Fonacier, Danielle Kelly, Vagner Rocha and Andy Varela, but the bigger story is that the event is asking them to compete in a setting designed to force more action and fewer pauses. For a title opportunity that drew Fornarino away from ADCC 2026, that tradeoff is part of the bet.
By the time the live stream starts, UFC BJJ 10 will already have clarified its purpose. It is not just another no gi Brazilian jiu-jitsu card in Las Vegas. It is a championship night meant to crown, test and reshape the divisions at once, and the first answer should come quickly from the main event: whether Tackett extends the run that has carried him to the top, or whether Gracie turns his unbeaten stretch into the night’s biggest upset.
