Longest UFC title reign
Silva held the middleweight title for over six and a half years, from October 2006 until July 2013, the longest continuous championship reign in UFC history.
MMA records span the sport's short, dense history, from the ancient-seeming early tournaments to the analytics-driven present. Because the UFC dominates the elite level, most all-time marks are set inside its Octagon, though the sport's records also live in PRIDE, ONE Championship and beyond.
The numbers below capture the extremes of the sport — the longest reigns and streaks, the fastest finishes, the most prolific finishers, and the commercial peaks that turned MMA into a global business. Where figures continue to move, they are anchored to a recent season.
