Ketlen Souza vs Ariane Carnelossi Fight Breakdown

Introduction

The women’s strawweight clash between Ketlen Souza and Ariane Carnelossi is set to ignite the preliminary card of UFC Fight Night: Muhammad vs. Bonfim on Saturday, June 6, 2026. This action-packed evening takes place at the UFC Apex in Las Vegas, Nevada, and the opener for the televised prelims is scheduled to begin at 6:00 PM PT (9:00 PM ET). Fight fans tuning in via UFC Fight Pass and ESPN+ will be treated to an intriguing stylistic matchup that sees the heavy-hitting boxer Ketlen Souza (16-6-0) as the clear betting favorite, while Muay Thai specialist Ariane Carnelossi (15-4-0) enters as the underdog looking to defy the odds.

Souza arrives in Las Vegas on an impressive run of finishes and consistently high output. At –265 on the American odds board with leading sportsbooks like BetOnline.ag and BetUS, she commands respect not just for her power—8 career knockouts and a 56% significant strike accuracy—but also for her durability and defensive acumen (53% sig strike defense). The 31-year-old Brazilian boxer has demonstrated a knack for dictating range, maintaining pristine footwork, and nullifying takedown attempts with a 54% takedown defense rate. Her average fight time of just under eleven minutes and five first-round stoppages underscore her ability to seize opportunities early and often.

Standing opposite in the blue corner is 32-year-old Ariane Carnelossi, a Muay Thai savant who brings a different challenge. Listed at +225 (BetOnline.ag) and +218 (BetUS), Carnelossi is very much the underdog but carries dangerous weapons in her clinch, kicks, and elbows. With nine knockouts already on her résumé, she’s proven she can end fights both standing and on the mat—she boasts two submission victories and a 50% takedown success rate. Despite coming off a submission loss to Talita Alencar in November 2025, Carnelossi has rebounded admirably, showcasing improved grappling defense (albeit at 23%) and a willingness to mix striking ranges.

When these two Brazilians square off, fans should expect a high-pace striking duel punctuated by moments of clinch work and scrambling exchanges. Souza’s boxing fundamentals and jab will be tested by Carnelossi’s leg kicks and Muay Thai entries, while Souza will look to keep the fight standing and at her preferred range. On paper, Souza’s superior takedown defense and striking accuracy tilt the scales, but Carnelossi’s underdog profile, durability, and finishing pedigree mean she can never be counted out.

As the prelim clock ticks down at the UFC Apex, all eyes will be on this pivotal 115-pound showdown. Whether you’re a seasoned bettor or a casual fan, understanding the strengths, weaknesses, and recent form of Souza and Carnelossi will be key to anticipating how this fight unfolds.
