Jai Opetaia (29-0, 23 KOs) faces Brandon Glanton (21-3-0) in the main event of Zuffa Boxing 4 on Sunday at the Meta APEX in Las Vegas, Nevada. This 12-round cruiserweight boxing odds bout is headlining Dana White’s Zuffa Boxing promotion (the UFC parent company’s boxing venture). Correlate that it features the inaugural Zuffa Boxing World Cruiserweight Championship. Opetaia, the current IBF and The Ring magazine cruiserweight champion (and lineal champ in some views), has expressed intent to defend his IBF belt. However, there’s ongoing ambiguity/sanctioning drama.
Meanwhile, Zuffa is pushing its own new title. But it’s unclear if the IBF fully recognizes this as a mandatory defense. Some sources list it as for the IBF/Ring belts. While others highlight the tension between Opetaia and Zuffa. Opetaia, a southpaw with elite skills, power, and a recent stoppage streak (last four opponents KO’d), is widely seen as the best cruiserweight today. Glanton is a tough, power-punching American pro. But he has losses to solid opponents like David Light, Chris Billam-Smith, and Soslan Asbarov, which mark him as a step down in competition.

Opetaia vs. Glanton Zuffa Boxing World Cruiserweight Championship
Jai Opetaia is an undefeated Australian professional boxer widely regarded as the world’s top cruiserweight. Opetaia, 30, was born in Sydney, New South Wales, and he resides in Gold Coast, Queensland. He fights as a southpaw with a height of 6’2″ (188 cm) and a reach of 76″ (193 cm). Consider that his professional career began in 2015, and he boasts a perfect 29-0 boxing betting odds record (23 KOs), giving him an impressive 79% knockout rate.
Opetaia is the current IBF cruiserweight champion, The Ring magazine cruiserweight champion, and is considered the lineal champion by many sources. Opetaia is ranked as the #1 cruiserweight by major outlets (The Ring, ESPN, etc.). Additionally, he is a contender in the pound-for-pound division. Later on, he was recently signed with Zuffa Boxing (Dana White’s UFC-affiliated boxing promotion) in early 2026, marking a major career move.
Accordingly, this matchup looks heavily one-sided on paper. Opetaia brings superior speed, footwork, technical boxing, southpaw advantages, and devastating power (high KO rate ~79%). He’s coming off a stoppage win over Huseyin Cinkara (though noted as somewhat sloppy by some observers, still dominant). Concurrently, his recent form shows he’s stopped four straight, showcasing finishing ability and range control.
Brandon Glanton offers aggressiveness and knockout power, which could pose a threat if Opetaia gets careless or if it turns into a brawl early. However, Glanton’s resume shows he’s been outclassed against top-tier cruiserweights, lacking the elite defense or ring IQ to handle Opetaia’s style. Analysts describe Glanton as “capable” but “found wanting” against better competition.
Opetaia vs. Glanton SBG Best Bets
On the whole, this is a classic mismatch. Opetaia is considered one of the most complete and exciting fighters in the cruiserweight division, blending technical mastery with finishing power. To conclude, the March 8 fight is a big showcase in his Zuffa debut—expect high-level boxing and likely a statement performance.
Main Pick:
Jai Opetaia.
