Jai Opetaia banked another statement win on Sunday in Las Vegas, dominating Brandon Glanton over 12 rounds to become the first Zuffa Boxing cruiserweight champion and further cement his spot at the top of the division.
The fight headlined Zuffa Boxing 4 at the Meta Apex in Las Vegas on March 8, 2026, with Opetaia entering as The Ring magazine champion and widely regarded number one at cruiserweight. The bout had originally been advertised with the IBF belt on the line, but the sanctioning body pulled its recognition in fight week after objecting to the Zuffa strap being treated as more than a “trophy or token of recognition,” leaving Opetaia stripped of the title on the eve of the event.
Thatdecisioncreated an odd backdrop: Opetaia risked his standing in the division without the chance to leave with his full set of belts, while Glanton was handed a shot at the sport’s premier cruiserweight on a stage backed by the UFC machine.

Once the bell rang, the contest was far more straightforward than the politics around it.Opetaiaran away with a unanimous decision, all three judges returning identical tallies of 119–106 after 12 rounds that saw Glanton deducted two points and Opetaia one.
The Australiansouthpawused his footwork early, circling off the fence at the Meta Apex and beating Glanton to the punch with counters from the left side whenever the American tried to march in behind a high guard. As the rounds went by, Opetaia held his feet more, stepping into uppercuts and body shots against the shorter Glanton while still refusing to trade recklessly and give the puncher the openings he needed.

Glanton, a top‑10 contender with an 80‑plus percent knockout rate coming in, never stopped pressing and had pockets of success when he backed Opetaia to the ropes, but he struggled to land clean combinations. Frustration showed as the bout wore on: referee Allen Huggins took a point from Glanton in round six for holding and another in the eighth for low blows, while Opetaia lost a point of his own in the eleventh for holding in close. Even with the deductions, the cards reflected what viewers saw: a one‑sided fight in which Glanton’s resilience kept him in it but never threatened to flip the script.
On paper, the stakes revolved around hardware and future leverage. Opetaia walked away as the inaugural Zuffa Boxing cruiserweight champion and retained The Ring title, adding a new belt in a market Zuffa hopes to grow. The IBF situation leaves him without an alphabet strap for now, but his performance in a high‑visibility main event should help when negotiations start for unification or a route back to that belt.
For Glanton, the loss drops him to four defeats and stalls his push toward a traditional world title shot, yet going 12 rounds with Opetaia on a UFC‑backed broadcast keeps his name in the mix as a durable contender who can test anyone at 200 pounds.
