The numbers are strong. ONE and Bellator are the fastest growers other than FI. Compare their follower growth percentage to the UFC-
ONE Championship averaged 29 million global viewers per event in 2019, according to Chatri Sityodtong, the Singapore-based martial arts promotion’s founder and chief executive.
Speaking during the first day of the SportsPro Asia virtual summit, Sityodtong cited Nielsen data as he outlined how ONE has prioritised free content to create mass reach since its inception in 2011.
“It’s a deliberate strategy,” Sityodtong said. “We purposefully go on all the free-to-air channels, the biggest broadcasters across Asia, we went on the biggest digital platforms. In the initial years we gave all of our content for free so our metrics literally skyrocketed.”
To illustrate that growth, ONE’s 100th live event in November of last year, which featured two cards and was broadcast in 145 countries, drew a record-breaking 85 million viewers worldwide."

Their recent TNT debut was not good though -- their western presence is struggling:
ONE Championship has been known for routinely making bold claims about strong ratings and viewership amounting to billions, but their actual numbers from their 2021 debut on TNT weren’t good at all.
MMA business and law expert Jason Cruz discussed the ratings:
“ONE will hold four events each week in April but one has to be concerned that it could only draw 196,000 viewers with one of the top cable shows on Wednesday night as its lead-in. Further, this was the big event with two top US names for people to watch. Yet, it couldn’t even garner 200,000 viewers.”
