Ketlen Vieira is a Brazilian mixed martial artist best known for her long run in the UFC women’s bantamweight division. Her exact net worth has not been publicly disclosed, but based on typical UFC fighter pay at her level and her reported career purses, it is estimated to be under $500,000.
Early Life & Family
Vieira was born on August 26, 1991, in Manaus, Amazonas, Brazil. She began training in Brazilian Jiu-Jitsu as a child and took up Judo at age twelve, eventually earning black belts in both disciplines under coach Andre Pederneiras. She also competed as a wrestler, winning national-level titles in Brazil. Vieira enrolled at Nilton Lins University to study law but left her studies to pursue a full-time career in mixed martial arts.
Rise to Fame
Vieira turned professional in October 2014 and built an undefeated 6-0 record within roughly 17 months, which earned her a contract with the UFC. She made her promotional debut on October 2, 2016, and quickly established herself as a dangerous grappler in the bantamweight division thanks to her wrestling and Judo background.
Career History
Across a decade in the UFC, Vieira compiled a 10-5 record in the promotion, finishing with notable wins over Sara McMann and Miesha Tate, along with a split-decision victory against former champion Holly Holm. She also suffered high-profile losses to Irene Aldana and Kayla Harrison. Vieira holds several UFC women’s bantamweight records, including the division’s highest career takedown-defense percentage. She left the UFC in 2026 and signed with the Professional Fighters League (PFL), where she was booked to challenge Cris Cyborg for the PFL women’s featherweight world championship in August 2026.
How They Built Their Wealth
Vieira’s income has come primarily from UFC fight purses, win bonuses, and performance incentives accumulated over roughly ten years and fifteen bouts in the promotion, followed by a new contract with the PFL. As is common for fighters outside the sport’s biggest stars, the bulk of her earnings come from base pay and bonuses rather than major outside endorsements.
Personal Life
Vieira has kept her personal life largely private and has not publicly disclosed details of her family or relationships beyond her mother, Socorro Freitas.
Ketlen Vieira’s net worth remains undisclosed but is estimated at under $500,000, built over a decade-long professional MMA career spent almost entirely in the UFC’s bantamweight division.
