Deontay Wilder vs. Jai Opetaia Official: Dana White Announces Explosive Heavyweight Fight for Fury vs. Joshua Netflix Card

Former WBC heavyweight champion Deontay Wilder faces undefeated cruiserweight king Jai Opetaia on December 11 in Cardiff, Wales, as Dana White and Zuffa Boxing deliver a blockbuster co-main event.

The boxing world received another major announcement Wednesday as UFC CEO and Zuffa Boxing executive Dana White officially confirmed Deontay Wilder vs. Jai Opetaia for December 11, 2026, at Principality Stadium in Cardiff, Wales.

The heavyweight matchup will serve as the co-main event for the highly anticipated Tyson Fury vs. Anthony Joshua showdown, with the entire event streaming worldwide on Netflix.

The announcement adds considerable firepower to an already historic boxing card, matching one of the most feared knockout artists in heavyweight history against an undefeated cruiserweight champion looking to establish himself among boxing’s biggest stars.

Dana White Confirms Wilder vs. Opetaia for December 11

White made the announcement through social media, confirming that the former heavyweight champion and undefeated Australian superstar will meet in a scheduled 12-round contest.

The UFC executive emphasized the incredible finishing ability of both competitors, noting that Wilder and Opetaia have combined for 67 career knockouts.

The fight also represents another major opportunity for Zuffa Boxing, the boxing venture associated with White and TKO Group Holdings, as it continues expanding its presence in professional boxing.

For Opetaia, who signed with Zuffa Boxing earlier in 2026, the matchup offers an opportunity to introduce himself to a significantly larger global audience.

Deontay Wilder Looks to Reclaim Heavyweight Glory

DEONTAY WILDER | 45-4-1, 43 KOs

At 41 years old, Deontay Wilder enters the contest seeking another signature victory after experiencing a difficult stretch against elite heavyweight competition.

The former WBC heavyweight champion successfully defended his world title ten times between 2015 and 2020, building a reputation around his devastating right hand.

Following defeats to Tyson Fury, Joseph Parker, and Zhilei Zhang, Wilder returned to the winning column with consecutive victories over Tyrrell Anthony Herndon and Derek Chisora.

His April 2026 split-decision victory over Chisora demonstrated that the American knockout specialist remains competitive, although questions about his durability and conditioning continue to surround his comeback.

Against Opetaia, Wilder will possess a significant advantage in height, reach, and heavyweight experience.

Jai Opetaia Moves Up to Heavyweight With Undefeated Record

JAI OPETAIA | 31-0, 24 KOs

Australian boxing sensation Jai Opetaia enters the biggest fight of his professional career with a perfect 31-0 record and 24 knockout victories.

The 31-year-old southpaw established himself as one of boxing’s premier cruiserweights after defeating Mairis Briedis to capture the IBF world championship in 2022.

More recently, Opetaia defeated Brandon Glanton to claim the inaugural Zuffa Boxing cruiserweight championship before stopping Noel Mikaelian in September 2026.

Moving into the heavyweight division against Wilder presents an entirely different challenge.

While Opetaia possesses exceptional footwork, technical boxing ability, and combination punching, he will be facing an opponent with substantially greater natural size and proven heavyweight knockout power.

A victory could immediately position Opetaia as a serious contender in boxing’s most lucrative weight division.

Who Wins Deontay Wilder vs. Jai Opetaia?

The matchup presents one of boxing’s most intriguing stylistic battles.

Wilder possesses the type of one-punch knockout power capable of ending a fight instantly, while Opetaia brings superior technical combinations, movement, and the confidence of an undefeated champion.

For Wilder, victory would strengthen his case for another major heavyweight opportunity. For Opetaia, defeating a former world champion in his heavyweight debut would significantly elevate his international profile.

With Tyson Fury vs. Anthony Joshua headlining and Wilder vs. Opetaia serving as the co-main event, December 11 could become one of the most-watched boxing nights of 2026.
