Prajanchai PK Saenchai

Before bringing his talent to the world’s largest martial arts organization, two-sport ONE World Champion Prajanchai PK Saenchai had already left an indelible mark on Muay Thai.

The Bangkok native competed in over 400 professional bouts, squared off against the best fighters on the planet, and gained a massive following that admires his remarkable agility, devastating strikes, and impeccable defensive skills.

Prajanchai’s electrifying performances have earned him numerous victories and accolades across multiple divisions. Notably, he has etched his name in Muay Thai history by capturing both the prestigious Lumpinee Stadium and Rajadamnern Stadium World Titles in two different weight classes.

Regarded as one of the greatest pound-for-pound fighters, Prajanchai directed his career path to ONE Championship in 2021, receiving an opportunity to add more glimmer to his legacy.

In his highly anticipated debut, he dethroned his legendary compatriot Sam-A Gaiyanghadao by majority decision to capture the ONE Strawweight Muay Thai World Championship.

His reign was cut short in May 2022, but Prajanchai reclaimed the ONE Strawweight Muay Thai World Title in December 2023 and has held it ever since. Prajanchai also defeated Jonathan Di Bella in June 2024 to become the ONE Strawweight Kickboxing World Champion.

In October 2025, though, he lost the kickboxing gold to Di Bella in a rematch.
