Pantoja has constructed an eight-fight winning streak marked by impressive title accomplishments. He claimed the flyweight championship by defeating Brandon Moreno at UFC 290 in December 2023 and has since successfully defended the belt four times against Brandon Royval, Steve Erceg, Kai Asakura, and Kai Kara-France. His most recent victory came at UFC 317 in June 2025, when he submitted Kara-France in the third round to extend his streak. At 35 years old, Pantoja has established himself among the division’s elite through consistent performance against top contenders.
Van, at just 24 years old, earned his title shot through a recent surge in competitive standing. The Myanmar-born fighter compiled five consecutive UFC victories over an 11-month stretch following a TKO defeat to Charles Johnson. His most significant win came at UFC 317 when he defeated Brandon Royval by unanimous decision, an upset performance that ranked among the most impressive fights of 2025. Van is 3-0 in fights during 2025 and stands at 15-2 in his overall mixed martial arts record, with an 8-1 mark inside the UFC.
Experts remain divided on the outcome. Some predict Van‘s superior striking volume and power could keep the fight standing throughout five rounds, while others emphasize Pantoja’s proven ability to implement wrestling to score in championship bouts.
