When Did ONE Championship Begin Sanctioning Muay Thai?
ONE Championship officially began promoting Muay Thai bouts in 2018 following the launch of ONE Super Series, its dedicated striking division for Muay Thai and Kickboxing.
The first ever Muay Thai bout in ONE Championship took place on January 26, 2018, when Sam-A Gaiyanghadao defeated Joseph Lasiri at ONE: Global Superheroes.
Later that year, Sam-A became the inaugural ONE Flyweight Muay Thai World Champion after defeating Sergio Wielzen in May 2018.
How Often Are ONE Championship Muay Thai World Titles Defended?
ONE Championship World Champions are generally expected to defend their titles regularly in order to maintain championship status and remain active within their division.
However, there is no publicly stated mandatory defence frequency outlined in ONE Championship’s official rules or on their website.
How This List Is Compiled
This list is generated using fight records stored in the Muay Thai Records database. It includes every bout in which a ONE Championship Muay Thai World Title was won or successfully defended, based on officially sanctioned results.
The data is reviewed and updated daily. New title wins and defences are added as soon as verified results are published, ensuring the list remains current and accurate.
Only ONE Championship Muay Thai World Title bouts are included. Kickboxing, MMA, submission grappling, and interim title bouts are excluded, as are exhibitions and unsanctioned contests.
