UFC Lightweight Champion Justin Gaethje has recognized Arman Tsarukyan as his next potential challenger following Tsarukyan’s dominant first-round knockout of Mauricio Ruffy at UFC 331. Gaethje, who claimed the lightweight title by stopping Ilia Topuria at UFC Freedom 250 in June 2026, is currently recovering from minor injuries and expects to return to competition next year. Although Gaethje's endorsement of Tsarukyan is not the final decision, it signals the rising contender's growing legitimacy as a top title contender in the 155-pound division.

Tsarukyan’s recent performance has earned praise from UFC President Dana White, who said Tsarukyan “completely flipped the script” on his title contention. Tsarukyan has been on a six-fight winning streak and has been pushing aggressively for a title shot, even accusing Gaethje of avoiding his name and preferring to pursue a rematch with Topuria or seek large sums like $15 million. Despite Tsarukyan previously withdrawing from a scheduled bout against Islam Makhachev in 2025 due to a back injury, his dominant KO victory at UFC 331 reaffirmed his right to fight for the championship.

Although Ilia Topuria, the former champion whom Gaethje defeated, has called for an immediate rematch, Tsarukyan’s recent showing changes the dynamics within the lightweight division. The UFC likely still controls the official matchmaking, and Gaethje would have to comply with a rematch if UFC leadership opts for it or risk being stripped of the belt. However, Tsarukyan’s rise and competitive momentum make him a compelling challenger for the belt, and he is reportedly requesting a fight as early as December to secure his long-sought title opportunity.

Looking ahead, the UFC will continue showcasing rising talent with an upcoming card at the Apex in Las Vegas on September 26, 2026, headlined by Raul Rosas Jr. vs. Raoni Barcelos. While the lightweight title picture remains unsettled with potential scenarios involving Tsarukyan, Topuria, and Gaethje, the division is poised for high-stakes clashes next year once Gaethje fully recovers and the UFC finalizes its matchmaking plans. Tsarukyan’s performance and ambition make him a key figure in the narrative around who will challenge Gaethje for lightweight supremacy.
