Even as the Ultimate Fighting Championship surges in virtually every measurable popularity metric, including Pay Per View buyrates, television ratings, and merchandise sales, enormous room for growth remains in its capacity for large venue ticket sales. Even in 2010, the average fan attendance for recent UFC events remained decidedly middle-tier, with overall attendance rates for major UFC Pay Per View events hovering between 10,000 and 20,000 fans. The venues supporting UFC live events are almost exclusively "arena" (sub-40,000 person) class venues as opposed to "stadium" (40,000 person and over) class venues.

Those who doubt the ability of mixed martial arts to expand into large-scale baseball, football, and European soccer stadium venues need only look to the history of live attendance of combat sporting events to prove otherwise. As early as July 4, 1921, barely two decades into the nascent rise of professional boxing as a major American spectator sport, more than 90,000 fans attended the light heavyweight boxing "Fight of the Century" pitting Jack Dempsey against Frenchman Georges Carpentier just across the river from New York City. Dempsey-Carpentier was a landmark sporting event, the first of any sport to gross over $1,000,000 from a live gate, and the first to be broadcast on live radio. From that time on, major boxing events were routinely held in front of audiences in excess of 60,000 fans in venues such as the old Yankee Stadium. More than thirty championship boxing bouts in all were held in Yankee Stadium before its demolition in 2008. Attendance totals of roughly 50,000 were not unusual, such as the 47,000 who witnessed an aging "Sugar" Ray Robinson fall to Joey Maxim in June of 1952.

Recent UFC fans might also be surprised to learn that history's largest mixed martial arts sporting events as measured by fan attendance have taken place exclusively outside of the United States. The current record for live attendance of an MMA event is now (and surely will be for some years to come) the August 2002 inaugural Pride Shockwave event held in Tokyo National Stadium in Tokyo, Japan. Reportedly 71,000 fans attended the event, a truly massive crowd for any event regardless of the sport. Pride Shockwave featured Mirko Filipovic defeating national hero Kazushi Sakuraba in the main event, and the event was such a success that the promotion's annual Shockwave series continued to draw some of the largest crowds in MMA history for years to come. Indeed, as is amply demonstrated by the listing below, 19 of the 20 largest events in MMA history as measured by fan attendance were Pride FC events.

The three largest UFC events to date as measured by fan attendance, UFC 124, UFC 97 and UFC 83, were also each held outside of the United States, as well as in the same venue, Montreal, Quebec, Canada's Bell Center. Over 21,000 fans were in attendance for each of the three events.
