Amanda Ribas Record: 12-7-0

Breakout run

The defining stretch of Ribas's career came across 2019 and 2020. In October 2019 she handed unbeaten grappling ace Mackenzie Dern her first professional loss via unanimous decision, then beat Randa Markos by decision in March 2020. Her most famous moment followed at UFC 251 in July 2020, where she submitted Paige VanZant with a first-round armbar in what proved to be VanZant's final UFC bout. The win cemented Ribas as a legitimate contender and one of the promotion's rising stars.

Contender years and setbacks

The climb met resistance. Ribas was stopped by Marina Rodriguez in early 2021, bounced back to outpoint Virna Jandiroba, then traded results with the division's best – a split-decision loss to Katlyn Cerminara, a decision win over Viviane Araujo at UFC 285, and a TKO defeat to Maycee Barber in 2023. She produced one of her flashiest finishes that November, stopping Luana Pinheiro with a spinning wheel kick and follow-up punches. Recent results have been tougher: a five-round decision loss to former champion Rose Namajunas in 2024, an armbar defeat in a 2025 rematch with Dern, and a TKO loss to Tabatha Ricci, leaving her at 12-7.

Fighting style

Ribas is a grappling-first fighter who has worked hard to round out her striking, and her finish breakdown reflects that balance – of her 12 wins, four come by submission, three by knockout and five by decision, a 58% finish rate. Her judo and jiu-jitsu black belts give her elite control, slick takedowns and a dangerous submission game, while her standup has grown bold enough to land spinning kicks. The honest flaw is durability under fire: four of her seven losses have come by knockout or TKO, showing that aggressive, heavy-handed strikers can punish her when exchanges break out of her preferred grappling range.

Career highlights

• Spoiling an unbeaten run — outpointed previously perfect Mackenzie Dern in 2019 to hand the grappling star her first pro loss.
• UFC 251 armbar — submitted Paige VanZant in the first round on a pay-per-view stage, her signature highlight win.
• Spinning-kick finish — stopped Luana Pinheiro with a spinning wheel kick and punches, proof of how far her striking has come.
