Final result: Robelis Despaigne wins by split decision (3 rounds). Correctly predicted Robelis Despaigne to win, but missed the method – predicted a KO/TKO finish while the fight went the full distance and ended by split decision.
🧾 Prediction Summary
This is a classic heavyweight crossroads fight between two massive punchers who need a win badly. Tai Tuivasa brings his trademark pressure and boxing power but arrives on a long losing skid with durability questions after five straight defeats, while Olympic taekwondo medalist Robelis Despaigne brings freakish size, length and nuclear first-round power with all of his wins coming by early KO. The key factors are distance control and chin — if Tuivasa can get inside the 87-inch reach and turn it into a brawl he can land, but Despaigne's speed, straight punches and front kicks at range, plus his enormous favourite status with the bookmakers, make him very dangerous early while Tuivasa fades late. Prediction: Robelis Despaigne to win by KO/TKO in round 1-2.

🥊 In-Depth Fighter Analysis
🔴 Tai Tuivasa
Tai 'Bam Bam' Tuivasa is still one of the most fan-friendly heavyweights in the UFC – a forward-moving brawler with heavy hands, a solid left hook and a willingness to trade in the pocket. At his best he overwhelms opponents with pressure, dirty boxing against the fence and big overhands, and 13 of his 14 wins have come by knockout. The flip side has been exposed during his current slump – his defence is porous, head movement is limited, and he has absorbed a lot of damage in recent wars.
Coming into UFC 331 he is on a five-fight losing streak against high-level heavyweights, and confidence and chin durability are the main concerns. His takedown defence has historically held up at around 54-55%, enough to keep the fight standing where he wants it, but his path to victory here is narrow: close distance quickly, crowd the much longer Despaigne, work the body and force a phone-booth exchange where his experience in deep waters could matter. If he cannot get inside early, he risks being picked apart at range.
- Record: 14-10-0 (13 KOs, 0 submissions) — 1 No Contest in 25 pro fights
- Signature weapon: close-range boxing and pressure — 93% of wins by KO/TKO, famous for shoey celebration and walk-off power
- Defence: takedown defence ~54%, but absorbs 4.2 significant strikes per minute; chin has been cracked in recent KO losses
- Recent form: L-L-L-L-L in last 5 UFC appearances (losses to Volkov, Pavlovich, Tybura, Spivak and Lewis), desperate for a win to stay on roster
- Key to victory: cut distance behind high guard, clinch and dirty box, don't kick at range — force Despaigne to fight backwards under pressure
🔵 Robelis Despaigne
Robelis 'The Big Boy' Despaigne is a unique heavyweight prospect — a 2012 Olympic taekwondo bronze medalist from Cuba who transitioned to MMA late and brings truly elite physical tools at 6'7" with an 87-inch reach. He is a pure explosive striker: lightning-fast straight punches, front kicks and jumping attacks for a man his size, with devastating first-round power. All six of his professional wins have come by KO/TKO, five of them inside the first round, often in under two minutes.
His limitations have also shown at UFC level: cardio beyond round one is untested and suspect, wrestling and ground game are still raw, and he has been outworked when opponents survived the initial storm and pushed grappling and clinch pressure. In this matchup, though, the stylistic matchup favours him — Tuivasa rarely wrestles and will happily stand and trade at a range where Despaigne's length and speed advantage is massive. If he keeps the fight long and manages his gas tank, he is likely to find the finish early.
- Record: 6-2-0 (6 KOs, 0 submissions) — 100% finishing rate, all wins in round 1
- Signature weapon: taekwondo-based distance striking — long jab, straight right and front kick, enormous one-punch KO power
- Defence: 78% takedown defence in small UFC sample, but cardio drops sharply after 7-8 minutes; absorbs little but defence relies on distance, not head movement
- Recent form: W-W-W-L-L in last 5 (started 5-0 with brutal KOs, then back-to-back decision losses to Waldo Cortes-Acosta and Austen Lane before rebound)
- Key to victory: use reach to stay long, pump jab and teep, avoid brawl on the fence — pick Tuivasa apart and finish before cardio becomes a factor

📊 Head-to-Head History
These two have never met before as professionals, so there is no direct head-to-head history. Stylistically it is a pure striker vs striker matchup with no common opponents in the UFC to date, though both have faced the broader heavyweight gatekeeper pool. Both prefer to keep the fight standing and hunt for the knockout, which historically suggests a short fight rather than a grappling or decision-based affair.
🤖 Extended AI Analysis
GPT-5.5 • Styles match-up
Despaigne wants a long, kickboxing fight at range behind his jab and front kicks, while Tuivasa wants to close to boxing range and brawl. Despaigne rarely shoots takedowns and Tuivasa almost never does either, so this is almost certain to stay standing where the longer, faster starter has the edge.
DeepSeek-R2 • Form and statistics
Tuivasa is on a five-fight losing skid with three KO losses and has absorbed heavy damage, while Despaigne is 6-2 with a 100% KO finishing rate and all wins in round one. Market prices near 1.11 for Despaigne imply an ~86-88% win probability, driven by that finishing upside versus Tuivasa's durability concerns.
Gemini 3 Pro • Size and physicality
Despaigne holds massive physical advantages at 201cm with 221cm reach versus 188cm / 191cm for Tuivasa, a +30cm reach differential. That length plus taekwondo speed makes it very hard for Tuivasa to enter without taking clean straight shots.
Claude Opus 4.8 • Key exchanges
The decisive exchange is the first 3-4 minutes: if Tuivasa can walk through one or two shots and pin Despaigne to the fence, his dirty boxing could turn it, but if Despaigne keeps it at kicking distance and lands early, Tuivasa's tendency to fade and get stopped late in exchanges points to an early finish.

🎯 Tactical Breakdown & Scenarios
Favourite finishes early (62%)
Probable score: Despaigne by KO/TKO in round 1-2
Despaigne keeps it long behind jab and teep, hurts Tuivasa coming in and finishes with straight punches as Tuivasa shells up on the fence. Fits his 6 first-round KOs and Tuivasa's recent KO losses.
Win on the judges' cards (23%)
Probable score: Despaigne by decision or late TKO
Tuivasa survives the opening storm by clinching and wrestling against the fence, but Despaigne wins rounds at range and either takes a clear decision as Tuivasa gasses or finds a late stoppage.
Underdog upset (15%)
Probable score: Tuivasa by KO in round 1-2
Tuivasa closes distance, drags Despaigne into a brawl and lands his left hook/overhand inside the long reach. Despaigne's cardio and chin in extended exchanges remain his biggest liabilities.
🏆 Final AI Consortium Verdict
🎯 Final Prediction
Robelis Despaigne to win by KO/TKO
Reach, hand speed and first-round power heavily favour Despaigne against a pressure brawler on a five-fight skid who must enter the exact range where Despaigne is most dangerous. Tuivasa's only path is an inside brawl, but the market and stylistic matchup point to Despaigne finding the finish before his cardio is tested.

The heavyweight bout is scheduled for UFC 331 on September 19, 2026 at 23:40 UTC (19:40 ET / 16:40 PT) at the Crypto.com Arena in Los Angeles, USA. It is a 3-round heavyweight contest (5 minutes per round).
The prediction is for Robelis Despaigne to win by KO/TKO, most likely in rounds 1-2. His reach, speed at distance and 100% KO finishing rate match up well against Tuivasa, who is on a five-fight losing skid and must walk through long straight shots to get inside.
Market average odds make Robelis Despaigne a heavy favourite at around 1.12 (about 86-88% implied probability) and Tai Tuivasa the underdog at around 5.65. The market also strongly favours an early finish: Under 1.5 rounds is around 1.53 and Fight ends inside the distance is around 1.30.
The fighters have never met before as professionals, so there is no direct head-to-head record. Both are pure strikers who prefer to keep the fight standing and have never won by submission, with 13 KOs for Tuivasa (14-10) and 6 KOs for Despaigne (6-2).
Robelis Despaigne is the key man — his 201cm height, 221cm reach, taekwondo jab/front kick and first-round power will dictate the fight if he keeps it long. For Tai Tuivasa to win he must be the other key factor: close distance quickly, pin Despaigne to the fence and turn it into a dirty boxing brawl where his pressure and left hook can land.
In the USA the card is expected to stream live on ESPN+ Pay-Per-View with prelims on ESPN+ and Disney+, and internationally via UFC Fight Pass and local UFC broadcast partners.
