ONE Record Book
ONE’s all-time leaders: career totals, one-night records and the numbers behind every ONE card we track.
Unofficial statistics compiled by UFCalendar from every completed fight in our database. Career boards need at least 5 bouts with tracked statistics and rate boards at least 50 attempts; BKFC is ranked only on its own boards.
