Justin Gaethje won the interim lightweight title via unanimous decision over Paddy Pimblett in UFC 324's main event, claiming the #1 contender spot in the lightweight rankings after the first UFC update of 2026. Ilia Topuria, the undisputed lightweight champion, is set to face Gaethje next upon his return. This positions Gaethje for a high-stakes unification bout in a stacked division. Meanwhile, Natalia Silva defeated Rose Namajunas on the main card, securing the next women's flyweight title opportunity. These developments shake up both divisions post-UFC 324. Expect title fight announcements soon as Topuria schedules his defense.
Reports emerging from UFC 324 indicate that Justin Gaethje captured the interim lightweight title with a unanimous decision over Paddy Pimblett in the night's main event, and the first UFC rankings update of 2026 subsequently placed him at number one in the lightweight division. The win is said to set up a unification bout against undisputed champion Ilia Topuria upon the champion's return, though no official announcement has been confirmed.
Gaethje's verified fighter data was not included in the input, so details of his record and career numbers are not available here. What the rankings update does indicate is that he now sits atop the lightweight contender ladder heading into what would be one of the division's most anticipated title fights.
Topuria, fighting out of Spain under the Climent Club banner, carries a 17-1-0 record and holds the undisputed lightweight title. Ranked number one pound-for-pound, the 29-year-old lands 4.81 significant strikes per minute at 48 percent accuracy, while also averaging nearly two takedowns and 1.1 submission attempts per 15 minutes — a well-rounded profile that makes any unification matchup a genuinely complex stylistic puzzle.
Also on the main card, Brazil's Natalia Silva handed Rose Namajunas a defeat in a women's flyweight contest, a result that reportedly places Silva next in line for a flyweight title shot. Silva, 29 and ranked fifth at 125 pounds, generates 4.81 significant strikes per minute at 45 percent accuracy from a southpaw stance, carrying a record of 20-5-1. Namajunas, the sixth-ranked flyweight at 34 years old, absorbed the loss and drops to 15-8-0.
Why it matters
- A Gaethje-Topuria unification bout would bring together the interim and undisputed lightweight titles in a high-profile matchup
- Topuria's pound-for-pound ranking means any title defense carries cross-divisional prestige
- Silva's reported next-contender status reshapes the women's flyweight picture at a time when the division is already competitive
- Neither title fight has been officially confirmed, so both announcements remain pending
