Elo UFC Rankings by MMA Compass

Fighters are ranked by their Elo rating, which is a measure of a fighter's strength. The rating is updated after each fight based on the result and the expected outcome. The expected outcome is calculated based on the fighters' ratings.

The rankings are divided by weight classes. Weight class is defined as the most common weight class of the fighter's last 3 fights.

Only the active fighters are ranked. A fighter is considered active if they have fought in the last 18 months (25/06/2023).
