DraftKings data cited by ESPN characterized the result as the largest known betting upset in UFC history. [ESPN]
The odds reflected the dramatically different expectations surrounding the two fighters.

Steveson was 4-0 as a professional mixed martial artist before facing Sharaf.
He had made his UFC debut at UFC 329 in July 2026 and knocked out Elisha Ellison in the first round.
That performance increased expectations that Steveson’s elite wrestling background could translate rapidly into success in the UFC heavyweight division. [UFC]
Why Was Gable Steveson Considered Such A Major UFC Prospect?
Steveson arrived in mixed martial arts with one of the strongest amateur wrestling résumés of any recent UFC signing.
He won a freestyle wrestling gold medal at the Tokyo Olympics and was a two-time NCAA Division I national champion at the University of Minnesota.
Those accomplishments led to considerable expectations surrounding his transition into MMA. [ESPN]
Steveson had also been training with former UFC heavyweight and light heavyweight champion Jon Jones.
Before UFC 331, Steveson said Jones and his coaches were helping him develop the striking, movement and decision-making skills necessary to supplement his elite wrestling. [UFC]
What Did Gable Steveson Say Before Fighting Sean Sharaf?
Steveson entered UFC 331 confident that he was improving rapidly.
He told the UFC before the fight that his UFC debut had taught him to remain active, understand when to engage and disengage, and become more comfortable dealing with strikes.
Steveson also said he wanted to continue fighting frequently because he was still relatively inexperienced in MMA despite his extensive wrestling background. [UFC]
The Sharaf fight demonstrated how costly even a brief defensive mistake can be at heavyweight, where a single clean punch can end a fight immediately.
Did Gable Steveson Leave The Octagon After Losing?
Yes.
After recovering from the knockout, Steveson left the Octagon before the official result was announced and before Sharaf’s hand was raised.
That decision attracted criticism from several UFC fighters and commentators, who argued that Steveson should have remained in the cage for the official announcement despite the disappointing loss. [MMA Fighting]
Why Was Gable Steveson Criticized After UFC 331?
Some of the criticism focused on Steveson’s decision to leave the Octagon before Sharaf was officially announced as the winner.
Former UFC champion and commentator Daniel Cormier said Steveson should have remained in the cage and accepted the result rather than leaving before the victory announcement.
Cormier also argued that Steveson, still early in his MMA career, should have relied more heavily on his elite wrestling rather than allowing the fight to remain a striking exchange. [MMA Fighting]

What Did Gable Steveson’s Manager Say After The Loss?
Steveson’s manager, Abe Kawa, publicly backed him following the knockout.
Kawa pointed to prominent fighters who suffered defeats early in their careers before becoming champions and said Steveson’s team continued to believe in his long-term potential.
He indicated that Steveson intends to return rather than allow the loss to end his MMA career. [Yahoo Sports]
Does The Loss End Gable Steveson’s UFC Career?
There is no indication that the UFC 331 defeat ends Steveson’s UFC career.
He remains only 26 years old and is still extremely inexperienced compared with most UFC fighters.
Before fighting Sharaf, Steveson openly acknowledged that he was still learning MMA and wanted to accumulate more cage experience before facing the heavyweight division’s best fighters. [UFC]
His manager has also said Steveson will return following the defeat. [Yahoo Sports]
The loss does, however, interrupt the rapid rise that appeared possible after Steveson’s successful UFC debut.
What Does The Loss Mean For Gable Steveson’s UFC Future?
The Sharaf knockout exposed one of the central questions surrounding Steveson’s transition from wrestling to mixed martial arts: how quickly he can develop the striking defense and cage instincts required to compete against experienced professional fighters.
Steveson’s wrestling remains an elite skill, but his MMA experience is limited.
Before UFC 331, he acknowledged that he still needed to learn when to pressure opponents, when to disengage and how to react naturally to incoming strikes. [UFC]
The 12-second knockout is therefore a significant setback, but it also occurred very early in Steveson’s MMA development.
