ONE Fight Night 27, the first U.S. primetime event of 2025, delivered non-stop action from top to bottom. Nine Muay Thai, submission grappling, and MMA fights featured everything from epic TKOs to submissions to nail-biting contests.
A new interim World Champion was crowned, a reigning titleholder's dominant run came to a halt, and John Lineker tasted his first defeat in Muay Thai. The winners of this event have bright futures ahead, so let's look at what's next for the biggest performers of ONE Fight Night 27.

Ever since Akbar Abdullaev stepped onto the global stage, he has shown the potential to become the next MMA superstar. He proved exactly that in the biggest fight of his career against reigning ONE Featherweight MMA World Champion Tang Kai in a catchweight non-title match.
Abdullaev displayed an impressive game both standing and on the ground, securing a TKO victory in round five. But he couldn't win the belt due to a mishap at the weigh-ins. Both Abdullaev and Tang should now rematch for the ONE World Title and settle their score, respectively.
Denice Zamboanga made history by becoming the Philippines' first-ever female MMA World Champion. She battered Alyona Rassohyna for nearly 10 minutes to secure the TKO victory in the dying seconds of round two. By winning the ONE Interim Atomweight MMA World Title, she confirmed her next opponent.
After the match, atomweight queen Stamp Fairtex came into the ring, embracing her friend and former training partner. Stamp is undergoing rehab for a knee injury. Combat sports fans are eagerly waiting for her return, and both fighters will look to unify belts and become the undisputed World Champion.
When two-time Brazilian Jiu-Jitsu World Champion Dante Leon joined ONE last year, fans expected strong performances from him, and he didn't disappoint. The Canadian powerhouse in Leon secured his second consecutive victory against former ONE Lightweight Submission Grappling World Title challenger Tommy Langaker.
Leon couldn't finish his foe, but he showed resilience in the 10-minute bout, settling the score from his 2018 loss to him. The 29-year-old now has his sights set on the ONE Lightweight Submission Grappling World Title currently held by grappling superstar Kade Ruotolo.
