Islam Makhachev’s position as the leading implied probability at 56.5% stems from his extended welterweight championship reign and undefeated streak since moving up from lightweight, which has kept him atop most current pound-for-pound lists. Tom Aspinall at 46.9% benefits from his heavyweight title defenses and size advantages that historically elevate champions in the division, while Ilia Topuria at 41.5% draws support from his recent lightweight title win and upcoming bouts that could elevate his ranking further. Recent developments include Sean Strickland’s middleweight title upset over Khamzat Chimaev at UFC 328, which dropped the latter in rankings, alongside Joshua Van’s flyweight title retention and Topuria’s expressed interest in a potential 2026 superfight against Makhachev. These factors, combined with long-term title trajectories, shape the current trader consensus through mid-2026.
