ONE Championship Unveils Eight-Man Field for 2026 Flyweight Muay Thai World Grand Prix

The single most dangerous bracket in combat sports just got its cast, setting the stage for a dramatic year-end showdown. On September 22, 2026, ONE Championship CEO Chatri Sityodtong unveiled the official eight-man field for the 2026 Flyweight Muay Thai World Grand Prix. Set to kick off in November, the tournament completely strips away the usual politics of combat sports matchmaking. Instead of carefully negotiated title defenses, the promotion is throwing the division's absolute elite into a single-elimination gauntlet. The format guarantees that the eventual winner will have survived the hardest possible path to the championship, facing a mix of established legends and hungry newcomers.[1][2]

"I am thrilled to announce the greatest world grand prix in history for Muay Thai," Sityodtong wrote on social media to break the news to the global fanbase. "Get ready for fireworks in November!" The promotion has locked in the names of the eight competitors, though the specific quarterfinal draws, the exact venue, and the total prize structure remain tightly under wraps. Fans and analysts are already speculating on the potential first-round matchups, knowing that any combination of these eight fighters will produce a main-event caliber contest. The November start date gives the athletes roughly eight weeks to prepare for the opening round of the grueling tournament.[1][5]

At the absolute top of the marquee sits 23-year-old Russian phenom Asadula Imangazaliev. The reigning ONE Flyweight Muay Thai World Champion enters the tournament as the man with the massive target on his back, putting his newly minted status on the line against the rest of the division. Imangazaliev has been an absolute wrecking ball since arriving in the Singapore-based promotion, racking up a flawless 8-0 record inside the ONE Championship ring. Even more terrifying for his prospective opponents is his finishing rate: seven of those eight victories have come by devastating knockout, proving his power translates perfectly to the four-ounce gloves used in ONE's Muay Thai bouts.[2][3]

Imangazaliev captured the vacant 26-pound gold strap just a few months ago, fighting in June at The Inner Circle 20 event. In that championship clash, he edged out Aslamjon Ortikov via a razor-thin split decision after five grueling rounds. That bout handed the highly touted Uzbekistani challenger the very first defeat of his professional career, snapping an incredible 24-fight win streak that had made him one of the sport's most feared rising stars. Now, Ortikov is officially back in the mix, placed directly into the same eight-man bracket and hunting for an immediate rematch to avenge the lone blemish on his 24-1 record.[1][2]

But the Grand Prix is far from just a two-horse race between the champion and his recent challenger. The tournament serves as the ultimate proving ground for two of Thailand's most revered living legends, both looking to cement their legacies. Former flyweight king Rodtang Jitmuangnon, now 29 years old, steps into the tournament field chasing the astonishing 275th victory of his storied professional career. Rodtang is looking to reclaim the division's top prize and reassert his dominance after a grueling two-fight saga with Japanese kickboxing superstar Takeru Segawa that tested his limits and forced him to evolve his aggressive style.[1][4]

Joining Rodtang in the veteran bracket is former bantamweight ruler Nong-O Hama, who drops into the flyweight tournament carrying an unbelievable 268 career wins and a long-standing reputation for technical perfection. Nong-O's inclusion pairs veteran title-level experience with the younger entrants who have been built across the promotion's regional circuits. The inevitable collision between that veteran mastery—honed over hundreds of stadium fights in Bangkok—and the surging youth movement of the international roster is exactly what makes this bracket so compelling for martial arts purists.[1][3]

Shimon Yoshinari represents the elite Japanese contingent, entering the Grand Prix with a flawless 7-0 promotional record that has quietly made him a dark horse to win the whole thing. The 23-year-old secured his tournament spot earlier this month at the ONE SAMURAI 3 event in Yokohama, Japan, where he delivered a spectacular performance. Yoshinari stopped the dangerous Suablack Tor Pran49 in the second round, moving directly from a regional showcase victory into the global tournament field and proving he possesses the finishing instincts required to survive the Grand Prix format.[3][4]

Thailand's Black Panther, 26, rides a massive six-fight winning streak into the November tournament window, adding yet another layer of hometown danger to the already stacked field. His recent performances have showcased a matured, measured approach to striking that makes him a nightmare matchup for the aggressive brawlers in the bracket. But the real wildcards of the tournament are the teenagers who fought their way onto the main roster through the grueling Friday Fights circuit at the iconic Lumpinee Stadium, proving they can handle the pressure of the global stage.[4][6]

Nineteen-year-old Lebanese prodigy Ramadan Ondash earned his coveted tournament slot after a gritty, star-making victory over Johan Ghazali back in July. He is joined in the youth movement by 20-year-old English standout Ubaid Hussain, who boasts a pristine 17-0 professional record. Hussain punched his ticket to the Grand Prix—and secured a life-changing $100,000 main roster contract in the process—by rattling off his eighth consecutive ONE Championship victory at The Inner Circle 28. These young fighters bring an unpredictable energy to a bracket filled with established veterans.[1][4]

The undeniable beauty of the Grand Prix format is its absolute finality and the sheer difficulty of the path to the trophy. There are no easy tune-up fights, no protective matchmaking from the promoters, and absolutely nowhere to hide once the cage door locks. Whoever survives the November quarterfinals will have to run through a relentless gauntlet of undisputed champions, undefeated international prospects, and legendary Thai icons just to touch the silver strap. It is a true test of attrition, skill, and willpower that will crown the undisputed king of the flyweight division.[2][5]
