Engine vs. Power, on the Strawweight mat for three rounds
Souza is the highest-volume, best-motor strawweight in this fight, coming off a clean UD over Bruna Brasil. Carnelossi hits hard and finishes early, but she has a documented history of production fade and was choked out in R3 by Talita Alencar. Brazilian vs. Brazilian — winner stays in the conversation, loser takes a step back. Market opens Souza a solid favorite.
ENGINE VS. IGNITION
Whoever Owns Minutes 8 to 15 Wins. That's Souza's Territory.
The axis of this fight is chronological. Ketlen Souza is the higher-volume, more accurate striker in this matchup — 4.01 significant strikes per minute, 56% accuracy — and she's shown a three-round engine in sequence: UD over Bruna Brasil, close splits against Angela Hill and Piera Rodriguez, UD 30-27 over Molly Mann. At 31, she's the strawweight who shows up on the cards and competes through every round. On the other side, Ariane Carnelossi is the power threat — nine knockouts in 15 wins, Muay Thai black belt, the kind of hands that can change a fight in one shot. The problem with Carnelossi is documented: she starts hot and fades. That's exactly what happened against Talita Alencar — came out sharp, went quiet in round three, got choked out. Add a history of long layoffs and back surgery, and the picture is clear. The question in this early prelim isn't who is more dangerous in the first five minutes — it's who is still producing at the twelve-minute mark. That answer has a name.
Truth A
Ketlen Souza has the engine and the volume. At 4.01 significant strikes per minute with 56% accuracy, a recent string of competitive octagon decision fights, and zero UFC stoppages by fade — she wins by imposing tempo, not by luck. The last two losses were close splits against legitimate strawweights. When the fight reaches deep water, it's Souza territory.
Truth B
Ariane Carnelossi hits harder. Nine knockouts in 15 wins, Muay Thai black belt, power that can end any round in the opening minutes. If the fight becomes an open stand-up exchange early, she has the shot that changes everything. She's also the one actively hunting takedowns in this fight — 1.08 per 15 minutes at 50% accuracy. But her UFC output numbers are weak (2.63 sig strikes per minute, 39% accuracy, 44% defense) and the danger is early, only early.
Tale of the Tape
Souza born Aug 18, 1994; Carnelossi Nov 1992. 31 vs. 33 — two years younger with less mileage from long layoffs.
Souza has a 3 cm height advantage — small edge but it favors the woman from Manaus.
Souza with a slight reach advantage — 161 cm vs. 156 cm. Helps with the jab and distance management.
Orthodox vs. orthodox — a clean stance mirror matchup. Outside hand and outside foot positioning will matter.
Carioca Academy (with time training Muay Thai with the Ribas family) vs. Inside Muay Thai. Pressure boxing against power Muay Thai.
Current Form
Ketlen Souza
UD across three rounds. Souza imposed volume, kept her hands active, controlled the cards, and got back on track.
Unanimous DecisionClose split decision. A tight three-round fight Souza lost on the cards — no damage, no stoppage.
Split DecisionSplit decision against a durable veteran. Another three-round fight decided on fine margins.
Split DecisionSubmission finish in R1. Souza found the back and sealed the rear-naked choke early — the hunter side of her game on full display.
Sub R1 (rear-naked choke)UD 30-27 across three rounds. Volume and distance management from bell to bell — total command.
Unanimous DecisionA fighter who has established herself in the octagon on engine alone. Souza is coming off a UD over Bruna Brasil in February 2026, returning to the win column. Before that, she dropped back-to-back split decisions — to Piera Rodriguez (Aug 2025) and Angela Hill (Feb 2025) — both legitimate strawweights, neither fight a stoppage or a blowout. In her stronger stretch, she submitted Yazmin Jauregui via rear-naked choke in R1 (Sep 2024) and beat Molly Mann by UD 30-27 (Apr 2024), showing both faces: she can finish early and she can dictate three full rounds. Sharp boxing out of Carioca Academy, with time spent training Muay Thai alongside the Ribas family. At 31, she's in the phase of imposing tempo — the kind of fighter who makes you pay for not keeping up.
Ariane Carnelossi
Started well and faded hard. Alencar found her back in R3 and finished with a rear-naked choke — the fade pattern fully exposed.
Sub R3 (rear-naked choke)Win by DQ in R2 after an illegal headbutt from Rodriguez. Not a performance win — a rulebook win.
Disqualification R2UD across three rounds. Godinez controlled pace and volume; Carnelossi couldn't sustain the pressure to the final bell.
Unanimous DecisionSubmission finish in R3. Carnelossi locked it up and closed — a clean grappling win.
Sub R3 (submission)KO in R2. The power showed up and ended it — the clearest evidence Carnelossi's hands are the real deal.
KO R2A fighter who scares you early and disappears late. Carnelossi is coming off a submission loss in R3 to Talita Alencar (Nov 2025) — she started hot, production fell off a cliff, and Alencar found her back and put her out with a rear-naked choke. That's the fade pattern that defines her risk profile. Before that, she beat Piera Rodriguez via disqualification in R2 (May 2024) after an illegal headbutt — a win on paper, not a statement. In her better years she submitted Istela Nunes (Oct 2021) and knocked out Liang Na in R2 (Apr 2021), which is where the real power credentials live. In between, she dropped a UD to Loopy Godinez (May 2022). Black belt in both Muay Thai and BJJ out of Inside Muay Thai. At 33, with a history of long layoffs and a back surgery in her record, Carnelossi carries genuine one-punch danger — but a gas tank that cashes the bill in the third.
Level of Competition
There is one direct common opponent: Piera Rodriguez. Souza lost to Rodriguez by split decision in Aug 2025 — a close, competitive fight decided on fine margins. Carnelossi beat Rodriguez in May 2024, but by disqualification in R2 after an illegal headbutt, not by imposing her will. Technically a win, not a statement. Looking at recent calibre: Souza has faced Angela Hill, Piera Rodriguez, and Bruna Brasil — legitimate UFC-level strawweights — and was competitive in all three. Carnelossi is coming off a finish loss to Talita Alencar and the DQ win over Rodriguez, with her best performances sitting years back in regional competition. Souza brings the higher and more consistent recent strength of schedule.

Win & Loss Distribution
Wins
KO/TKO
Submission
Decision
The surface looks similar — the context is not. Carnelossi has the more aggressive distribution on paper: 9 KO/TKO (60%), 2 submissions (13%), and 4 decisions (27%), with the power credentials built in regional competition and early UFC. Souza shows 8 KO/TKO (50%), 2 submissions (12.5%), and 6 decisions (37.5%), but the key detail is where those stoppages happened: most of Souza's finishes predate the UFC, and inside the octagon she has zero knockouts across six fights — winning purely on volume and decisions. Carnelossi's KO record is also predominantly regional or early-career. For method betting, Souza by decision is the most structurally probable path: her octagon game is built on tempo and output, not imposed finishes.
Losses
KO/TKO
Submission
Decision
Structurally important. Souza has six losses: 2 by KO/TKO (33%), 2 by submission (33%), and 2 by decision (33%) — an even distribution, and both recent losses were close splits, not stoppages. Carnelossi has four losses: 1 by KO/TKO (25%), 2 by submission (50%), and 1 by decision (25%). The number that matters: Carnelossi's most recent loss was a submission in R3 to Talita Alencar — exactly after fading — and two of her four career losses are by submission. Souza has never been stopped by accumulated damage in a recent octagon sequence. For method betting: Carnelossi gassing and getting caught late is a real pattern, and the most probable loss path for her here runs through Souza's volume in the final rounds.
Skills Profile

Striking Volume
+2 Souza
Souza at 4.01 per minute vs. Carnelossi at 2.63. Volume is the currency of this fight and Souza holds the bankroll.
Knockout Power
+2 Carnelossi
Carnelossi has nine KOs in 15 wins and Muay Thai black belt hands. Souza has zero UFC KOs. The knockout power lives with Carnelossi.
Boxing and Accuracy
+2 Souza
Souza at 56% accuracy with cleaner boxing technique vs. Carnelossi's 39%. When the fight gets technical, the edge is Souza's.
Takedown Defense
+2 Souza
Carnelossi actually hunts for takedowns more (1.08 vs 0.46 per 15 min), but she runs into Souza's 54% TDD vs her own 23%. The one absorbing the other's takedown attempts is Souza.
Grappling and Submission Defense
+1 Souza
Souza has never been finished by fatigue and has a recent rear-naked choke finish. Carnelossi is a BJJ black belt but was submitted by Alencar. Slight edge to Souza.
Cardio — Three Rounds
+3 Souza
Souza shows a three-round engine in a recent sequence of decision fights. Carnelossi fades and was caught in R3 running on empty. The decisive factor.
Carnelossi has the edge in the opening minutes — power, early impact, and Muay Thai hands that can close any round early — and she's the one actively hunting takedowns. But those takedown attempts walk into Souza's TDD wall (54% vs 23%), and in everything else — volume, accuracy, and above all the three-round engine — the advantage is Souza's. This fight is a race between Carnelossi landing her power shot (or connecting on a takedown) before she fades, and Souza imposing her tempo until the scorecards close. Three rounds with Carnelossi's documented fade: the clock runs for Souza.
Final Prediction
The Thesis
The thesis: Ketlen Souza wins because she has the higher floor in this fight — superior volume (4.01 vs 2.63 sig strikes per minute), superior accuracy (56% vs 39%), and a massive takedown defense advantage (54% vs 23%) in the exact area Carnelossi hunts most, and above all, a three-round engine going up against a fighter with a documented fade who started strong and got choked out in R3 by Talita Alencar.
The thesis: Ketlen Souza wins because she has the higher floor in this fight — superior volume (4.01 vs 2.63 sig strikes per minute), superior accuracy (56% vs 39%), and a massive takedown defense advantage (54% vs 23%) in the exact area Carnelossi hunts most, and above all, a three-round engine going up against a fighter with a documented fade who started strong and got choked out in R3 by Talita Alencar.
The path runs through Souza surviving the first five minutes where Carnelossi's power is a genuine threat, asserting clean boxing and distance management from R1 into R2, and closing the cards on accumulated volume as the fight gets later and Carnelossi slows. This falls apart if Carnelossi lands a clean power shot before the gas gives out.
Conviction
Conviction 7 (not elite) because: (1) Souza's floor — volume, durability, three-round engine — exceeds Carnelossi's ceiling of early KO or early sub; (2) the 31-point takedown defense gap shields Souza exactly where Carnelossi hunts most (1.08 attempts per 15 min vs 0.46 for Souza), removing a control path; (3) Souza competed at a higher recent level — close splits against legitimate strawweights — while Carnelossi's best wins are old, regional, or by DQ. But: Carnelossi's power is real — nine career knockouts; (b) the early-fight danger window is genuine, first ten minutes; (c) Souza has zero UFC KOs, so she doesn't impose finishes, which keeps the fight competitive as long as Carnelossi still has gas. That's why 7 — solid floor advantage, not a dominance read.
What Breaks This Pick
- 01
Carnelossi lands clean Muay Thai power in the first ten minutes before the gas drops
- 02
Carnelossi connects on takedowns (50% accuracy when she shoots) and holds top position, overcoming Souza's 54% TDD
- 03
Carnelossi's cardio holds above expectation and the fight turns into a competitive stand-up exchange all three rounds
Underdog Path
Carnelossi has a clear, time-gated path: land the Muay Thai power in the opening five to ten minutes while the gas tank is full and before her own fade becomes the story. She has nine career knockouts and the one-punch pop to end any round in that window. As a secondary route, she's the one actually hunting takedowns here (1.08 per 15 minutes, 50% accuracy), so mixing in grappling is on the table — but she runs directly into Souza's 54% TDD. If she can force a fire-fight at close range in R1 and land clean, she ends it before the clock flips against her.
Required Conditions
- Land clean power shots in the first ten minutes before the gas falls off
- Force stand-up exchanges at close range without ceding distance control to Souza's jab
- Survive Souza's R1 volume without accumulating damage that accelerates her own fade
— Precedent: Carnelossi's KO of Liang Na in R2 (Apr 2021) and the submission of Istela Nunes show she can finish when she gets on track early. The important caveat: those results came in regional competition or the beginning of her UFC run, not against strawweights operating at Souza's level — and her recent pattern is production fade followed by a late stoppage, as seen against Talita Alencar.
Verdict
Winner
Ketlen Souza
Method
Decision (volume)
Most Likely
- 01
Method
Souza by Decision
The most structurally probable path. Souza has zero UFC KOs across six fights — she wins on volume and decisions — and Carnelossi is durable enough to reach the scorecards but fades and slows. The implied probability is 45%; the estimate lands at 48-52% given the structural draw. A moderate edge and the pick most aligned with the thesis.
- 02
Total Rounds
Over 1.5 rounds
The early-finish danger exists — Carnelossi's power is real — but the tendency is for this fight to get past the first round and become Souza's volume bank. Careful if Carnelossi connects early, but statistically the distance management here favors going the distance.
- 03
Winner
Souza
Implied probability ~72%, estimate ~70%. Close to fair — no big direct value. Taking Souza straight is solid but the best return is in the method (decision) or parlayed with another card favorite.
- 04
Method Underdog
Carnelossi by KO/TKO
High-risk contrarian play. Only live if Carnelossi connects in the first ten minutes. Real probability 18-22%. The implied is 20% — estimate lands right there, no clear edge. This is a hedge, not a main play.
Most Likely Outcome
Souza by Decision
Best direct value in this fight. Combines the main pick (Souza wins) with the most probable method (decision). Souza has zero UFC KOs across six fights and wins on volume; Carnelossi is durable enough to reach the cards but fades and drops production. The implied is 45% and the estimate lands at 48-52% given the structural layout. Solid 4-7 point edge.

The Trap
Trap: Carnelossi by KO/TKO at Big Odds
The market will pay well on Carnelossi by knockout, and the surface case looks real — nine KOs in a career and Muay Thai black belt hands. But there are two holes. First, the bulk of those knockouts came in regional competition or early in her UFC run, not against strawweights operating at Souza's level. Second, Souza has never been knocked out by a clean sequence in the octagon's recent phase, defends 53% on the feet, and brings cleaner boxing technique. Betting a specific Carnelossi finish at long odds is betting on real power inside a narrow window — one that only exists in the first ten minutes, against a durable fighter whose default is to drag the fight into deep water where Carnelossi runs dry.
