ONE Fight Night 23 | Fight Highlights

One Championship (stylized ONE Championship or simply ONE; formerly One Fighting Championship (ONE FC) until January 2015) is a multinational combat sports promotion founded on 14 July 2011 by Chatri Sityodtong and Victor Cui.[2] Originally focused on mixed martial arts (MMA), ONE has since expanded to regularly hold events featuring muaythai, kickboxing, and submission grappling bouts, while also previously promoting boxing and lethwei matches. One held its first event on 3 September 2011 at the Singapore Indoor Stadium, and has since held over 200 events across Asia.[3]

ONE is considered to be Asia's largest combat sports promotion, with investors including GIC and Temasek Holdings, in addition to ICONIQ Capital, Mission Holdings, Sequoia Capital and Greenoaks Capital.[4][5] The promotion would reach a value of over $1 billion by October 2018.[6][7][8] In 2022, ONE's parent company, One Group Holdings, changed its legal operations from Singapore to the Cayman Islands.[9][10][11]

Sityodtong stated his goal was to create the first Pan-Asian martial arts company, and to promote "values of integrity, humility, honor, respect, courage, discipline, and compassion", which he believes Western MMA promotions have lost.
