What Are the Biggest UFC Upsets So Far in 2025?

The 2025 UFC season has already delivered a string of jaw-dropping upsets that have shaken divisions and altered championship trajectories. From underdogs toppling favorites to veterans reclaiming glory, these shocking outcomes underscore the sport’s unpredictability and the mantra that “anything can happen” inside the Octagon.

Raoni Barcelos’ Stunning Victory Over Payton Talbott

One of the biggest upsets of early 2025 came in January when Brazilian veteran Raoni Barcelos handed unbeaten prospect Payton Talbott his first professional loss. Entering the fight as a +440 underdog, Barcelos defied expectations with a dominant performance that included crisp striking and tactical grappling. Talbott, who had been riding a nine-fight win streak and was considered a top contender in the bantamweight division, was overwhelmed by Barcelos’ experience and skill.

Barcelos reflected on the significance of the win: “Beating a champion is going to be on my record, and that means a lot.” This victory not only revitalized Barcelos’ career but also sent shockwaves through the division, positioning him as a serious threat to the top contenders.

Carlos Vera’s Quick Submission Over Josias Musasa

At UFC Atlanta in June, Carlos Vera pulled off another major upset by submitting Josias Musasa with a rear-naked choke just 3:16 into the first round. Vera’s aggressive start and flawless execution caught Musasa off guard, ending the fight well before many expected. This victory showcased Vera’s evolving skill set and ability to capitalize on openings swiftly.

The win earned Vera Performance of the Night honors and instantly raised his profile among fans and analysts, marking him as a rising star capable of shaking up the rankings.

Narrative Shifts: Kamaru Usman and Jon Jones

While not traditional “upsets,” 2025 has seen significant narrative shifts for established stars like Kamaru Usman and Jon Jones, who have faced unexpected challenges altering public perception. Usman’s gas tank and endurance were questioned after a hard-fought win, while Jones’ recent performances sparked debate about his prime and consistency.

These shifts highlight how even dominant champions can face moments that upend expectations, contributing to the dynamic nature of MMA.

Other Notable Surprises

The year has also featured upset wins by fighters like Alice Ardelean over Rayanne Dos Santos and Hyder Amil defeating William Gomis, both of whom entered their bouts as underdogs. These victories emphasize the depth of talent in the UFC and the constant threat posed by rising fighters hungry to make their mark.

Historical Context: UFC’s Legacy of Upsets

UFC history is rich with unforgettable upsets, from Matt Serra’s shocking knockout of Georges St-Pierre to Julianna Peña’s submission of Amanda Nunes. The 2025 upsets, while perhaps not as monumental as those legendary moments, continue the tradition of unpredictability that defines the sport.

As MMA analyst Lucas Tracy noted, “The biggest narrative shifts and upsets in 2025 remind us that fighters evolve, and no one’s spot at the top is guaranteed.”

What These Upsets Mean for the Future

These surprising outcomes have significant implications for rankings, title contention, and matchmaking. Veterans like Barcelos are revitalizing their careers, while newcomers are forcing divisions to reconsider established hierarchies. For fans, these upsets add excitement and unpredictability, reinforcing the UFC’s reputation as a sport where underdogs can triumph and legends can be made.


The biggest UFC upsets of 2025 so far from Raoni Barcelos’ upset of Payton Talbott to Carlos Vera’s lightning-fast submission highlight the thrilling uncertainty inherent in mixed martial arts. As the year progresses, fans can expect more shocking results that will continue to redefine divisions and captivate audiences worldwide.
