Vitor Belfort leads UFC with 11 first-round knockouts

Vitor Belfort stands alone atop one of the UFC's most feared statistical categories, holding the all-time record with 11 first-round knockouts across his career in the promotion. Anthony Johnson sits second on that list with nine, while Poland's Michal Oleksiejczuk has claimed eight. A group of seven fighters — Sergey Pavlovich, Francis Ngannou, Andrei Arlovski, Cain Velasquez, Anderson Silva, and Derrick Lewis — are all tied with seven apiece.

Belfort, nicknamed "The Phenom," is a 49-year-old Brazilian southpaw who compiled a 26-14-0 professional record over a career that spanned multiple UFC title runs. Standing six feet tall with a 74-inch reach, he built his legend on explosive early-round finishing ability, a trait these numbers quantify better than almost any other metric in the sport.

Oleksiejczuk, 31, represents the active generation pushing into this elite company. The Polish southpaw carries a 22-10-0 record and lands 5.85 significant strikes per minute at 53 percent accuracy, making his eight first-round stoppages a product of genuine punch volume rather than fortunate timing.

Cain Velasquez, the former heavyweight champion from the United States, rounds out the group tied at seven. The American Kickboxing Academy product finished his career at 14-3-0 and was as dangerous with his hands as he was on the ground, averaging 5.13 takedowns per 15 minutes alongside 6.37 significant strikes landed per minute at 57 percent accuracy.

Why it matters

• Belfort's record of 11 first-round knockouts may be the most durable finishing benchmark in UFC history
• Oleksiejczuk, at 31 and still active, is the fighter on this list most likely to climb closer to the top over time
• The spread across multiple weight classes shows that first-round finishing power is not exclusive to heavyweight, complicating any simple narrative about divisional striking
