About Sangarthit Looksaikongdin
Sangarthit Looksaikongdin was never destined for an ordinary life.
Raised in a family that eats, sleeps, and breathes combat sports, Sangarthit grew up inside the walls of his family’s Looksaikongdin gym in Thailand. His parents wasted no time putting him on the path of a warrior, and Sangarthit – the 14th of 16 children – had his very first bout at the remarkable age of one year and eight months old.
The prodigy would continue to develop his skills in the years to follow and rack up more competition experience. However, by the time he was 15, he set his sights on professional boxing.
What followed was nothing short of extraordinary. Sangarthit bulldozed through the competition, capturing the WBA Asia Super Lightweight World Title at age 16 and defending it nine times without ever tasting defeat. His unblemished 19-0 boxing record, punctuated by nine knockouts, announced him as one of the continent’s most exciting young talents.
Yet even with World Title gold around his waist and an unbeaten slate to his name, Sangarthit – the brother-in-law of Rodtang Jitmuangnon – knew his story was far from complete.
In early 2025, the Thai phenom had a chance meeting with ONE Championship Chairman and CEO Chatri Sityodtong, who handed him the opportunity of a lifetime and offered him a contract to join the world’s largest martial arts organization. Sangarthit put pen to paper and signed without hesitation.
“When I met Boss Chatri, we discussed my goals,” he said. “After hearing the offer, I knew that if I didn’t take it, I might not get another opportunity like this in the next 10 years. I thought to myself that I should at least give it a shot. If I fail, I can always adjust and fix it. It’s about giving myself a chance to learn something new.”
Sangarthit proved immediately that he belonged with the world’s best strikers, as he blended his elite boxing with his Muay Thai prowess to overwhelm the competition. The Thai made an instant impact in his promotional debut in March 2025, defeating Super Yay Chan via unanimous decision and showing fans across the globe that he is a legitimate threat to the bantamweight kickboxing division’s top contenders.
For a fighter who has been seizing chances since before he could walk, it’s clear that Sangarthit is just getting started.
