- Elo (52% Daria) is provisional on both sides and misses Pereira's April 2026 KO win over Cowan
- Common opponent Montse Rendon: Daria won a unanimous decision, Pereira lost a split decision; a small edge to Daria, but dated
- Pereira is a 20-year-old on the rise, while Daria has alternated wins and losses and lost her last fight
- Daria's volume (4.13 landed per minute, 64% strike defense) points to a close, three-round striking fight
Write-up
There is no market line, so the priors are Elo and form. Elo has Zhelezniakova at 52%, but both ratings are provisional and Pereira's is stale. It lists her UFC record as 0-1 and misses her April 2026 knee KO of Hailey Cowan, so her true rating is likely around 1500, which makes this roughly a coin flip. The pipeline reports no common opponents, but there is one: Montse Rendon. Zhelezniakova beat Rendon by unanimous decision in March 2024; Pereira lost to her by split decision in September 2025. That slightly favors Daria, but the results are 18 months apart and Pereira was a 19-year-old in her first UFC fight. Zhelezniakova (4 UFC fights) outlands opponents by +0.75 strikes per minute and avoids 64% of strikes, but she has alternated wins and losses (L-W-L-W), lost her last fight to Melissa Croden, and was submitted by Ailin Perez with an arm triangle. Her 50% takedown defense is a leak if Pereira wrestles. Pereira is 20, 7-1, and coming off her first UFC win, a finish, which fits a fast-improving prospect. Daria is 30 and has shown no growth. I lean Pereira on trajectory, offset by the Rendon comparison and Daria's steady volume, so 52% honestly reflects a coin flip. A decision is the likely result: Daria has gone the distance in all three of her UFC decisions, and Pereira's UFC fights went one full distance and one finish.
- Zhelezniakova averages 4.13 significant strikes landed versus 3.38 absorbed per minute
- Both listed Zhelezniakova wins came by unanimous decision
- Pereira's recent knockout offsets some of Zhelezniakova's experience advantage
- Provisional Elo and inconsistent, sparse records warrant coin-flip confidence
- Neither listed layoff exceeds the approximately 450-day risk threshold
Write-up
Zhelezniakova narrowly gets the pick through her documented positive striking differential and decision-winning experience. She beat Montse Rendon, who beat Pereira, although that indirect comparison carries limited weight. Provisional Elo favors Zhelezniakova at 52%, but Pereira's listed April knockout win is missing from her statistical and Elo records. That finish strengthens Pereira's case and keeps this close. Pereira's missing statistics are not evidence of weak skills; conflicting records and duplicated entries further limit confidence. Listed layoffs of 185 and 171 days offer little separation. Method percentages are conditional on a Zhelezniakova win.
