Multiple UFC divisions feature active title landscapes in 2026 with several defenses and potential vacancies still ahead, including lightweight where interim champion Justin Gaethje and contenders like Arman Tsarukyan sit near the top, and welterweight where Islam Makhachev faces tests against rising options such as Shavkat Rakhmonov or others on the schedule. Recent mid-year shifts saw title changes or interim crowns in lightweight and middleweight, while established holders like Alexander Volkanovski in featherweight and Joshua Van in flyweight continue to navigate strong challenger pools. Upcoming numbered events and Fight Nights through the fall and winter provide concrete paths for new champions via official title bouts, with factors like fighter form, weight-class movements, and injury recoveries directly influencing division hierarchies and the likelihood of additional turnover before year-end.
