There is no market line for this fight, so the two priors are Elo (Luana 56%) and the matchup, and they agree. Yana is the bigger, longer-tenured bantamweight. She has fought at 145 and has a 1-inch reach edge (68 vs 67). She is an accurate, durable volume striker: 58% accuracy, 4.42 SLpM, +1.30 striking differential. Her three-fight streak over Chelsea Chandler, Miesha Tate and Macy Chiasson is a real veteran resume, all won by clean decision. Her weakness is defensive. She stops only 42% of takedowns and avoids only 50% of strikes, and Luana is built to exploit both. Luana averages 1.62 takedowns and 1.2 submission attempts per 15 minutes, with two submission wins in her last five (a keylock on Lisboa and a rear-naked choke on Agapova). At the same time she defends 80% of takedowns and 61% of strikes, so Yana is unlikely to turn this into a grappling fight of her own. The feed reports no common opponents, but there is one: Karol Rosa beat Yana by split decision in 2023, and Luana beat Rosa by unanimous decision in June 2026. That is a modest but relevant signal. Age and activity also favor Luana. She is 26 and fought 127 days ago. Yana turns 37 next month, has been out 386 days, and withdrew from an April 2026 bout with Norma Dumont for undisclosed reasons. That gap is below the ~450-day red-flag threshold, but the unexplained withdrawal adds some risk. The case for Yana is real: size, toughness and a pace that can win rounds on the feet if Luana's takedowns don't land. Luana also moved up from flyweight and has never been finished, so she won't have a power edge. I expect Luana to take rounds with clinch entries and top control and to threaten submissions without necessarily finishing a 135er who has gone the distance in each of her last five. 60% reflects Elo plus a matchup edge, with no market to confirm it.

Luana's 56% Elo baseline gets a modest boost from her grappling matchup: 1.62 takedowns per 15 minutes against Yana's 42% takedown defense, plus greater submission activity. Yana's superior striking differential and deeper UFC experience keep this competitive. Both have three consecutive wins in the enriched logs, but Luana has competed more recently. Yana's roughly year-long absence adds uncertainty; her withdrawal does not establish an injury. Recent decision wins support a distance outcome. Conflicting, duplicated structured histories limit confidence, so the enriched fight logs receive priority. Method probabilities describe the overall fight outcome.
