Floyd Mayweather vs Mike Zambidis | Betting Odds & Fight Preview

On 13 June 2026, Athens will host a 2nd clash of boxing and kickboxing in recent months. After Oleksandr Usyk barely gnawed his way through Rico Verhoeven’s defence and KO’d him in Giza, it’s time for a new showdown. Floyd “Money” Mayweather — the 50-0 former five-division world champion — steps into the ring against Mike “Iron” Zambidis, the Greek-Albanian kickboxing icon. The venue is the Telekom Center in the OAKA Olympic Complex – a fitting venue, the very same that hosted the 2004 Summer Olympics. 

While it’s not a professional contest and no records will be moved, Mayweather and local hero Zambidis should attract millions of viewers worldwide. In this preview, we cover the Mayweather vs Zambidis betting odds, both fighters’ backgrounds, the tale of the tape, and where to watch the event in the UK. All available markets are listed at 7bet.

Floyd Mayweather Jr. vs Mike Zambidis: Lore

Mike Zambidis – the Kickboxing Icon

Mike Zambidis is not a household name in the UK, but he’s a legend in Greece and kickboxing. Listen to this, Zambidis has amassed a 157-24 record in kickboxing with eighty-seven (87!) knockouts and 18 world titles across various divisions. That alone makes him one of the most decorated full-contact fighters in combat sports history. While his last pro fight was in 2015, and he has only one pro boxing bout under his belt, the Greek hero’s resume leaves no room for interpretation.

Floyd Mayweather Jr. – Undefeated G.O.A.T.

On the other side of the ring will be Floyd ‘Money’ Mayweather – a symbol that needs no introduction. The best defensive fighter of his generation or, possibly, ever. He beat everyone and everything that ever stepped into the ring with him. 

Even though it wasn’t always pretty, a 50-0 record with over 1.2 billion dollars in career earnings does all the talking necessary. As the American prepares for a historic showdown against Manny Pacquiao in September, this exhibition could be just what he needs to polish the guns before the really big bout.  

The question is straightforward – kickboxing or boxing – which discipline is going to come out on top?

Mayweather Jr. vs Zambidis: Betting Odds

This paragraph will cover and break down the main betting markets available for the Floyd Mayweather Jr. vs Mike Zambidis fight. It’s going to be a general overview. 

Please note that exhibition bout markets may differ slightly from those of standard professional contests. Furthermore, odds can change in either direction before the fight, so refresh the catalogue to see the latest prices.  

Most Popular Betting Markets:

• Winner – one of the most straightforward picks. Bettors choose either Mayweather Jr. or Zambidis to back. The bet wins if the selected boxer comes out on top after the final bell, whether it comes inside the distance or after the judges get involved. On paper, Mayweather Jr. is expected to come in as a heavy favourite, as you’d expect from the GOAT defensive boxer. 
• Round Total (Over/Under) – with 8 rounds on the clock rather than the standard 10 or 12, the Round Total market will have lower thresholds. In this market, bettors pick whether the bout is going to take longer (Over) or will end prematurely (Under) than a designated threshold. Historically, Mayweather Jr. doesn’t go for KOs too often, establishing a slow and steady rhythm to collect points when it matters. On the other hand, Zambidis’ best path to victory might be landing a devastating combo on an ageing American, so do your research.
• Winning Method – pick how the exhibition ends. Punters need to correctly guess both the winning fighter and the method of victory (KO/TKO or Points). The odds for these markets tend to be longer because of the multiple factors involved. Floyd hasn’t KO’d an opponent since the 4th round stoppage of Victor Ortiz in 2011, so early predictions imply that a decision victory might have the shortest odds. 
• Will the Fight Go the Distance – a simple binary pick with “Yes” or “No” bets. Select “Yes” if you think the scorecards will decide the outcome or “No” if you expect Floyd or Zambidis to take care of things inside the distance. Without the urgency of a title fight, this market is arguably the most intriguing on the card. Mayweather’s last three exhibitions produced two wins that went the distance and one no-contest.

Two more markets worth mentioning are Exact Round Betting and Round Group Betting. With the former, bettors must correctly identify the winner of the bout and the precise round in which the fight is going to finish. Odds are long because you need to guess two things correctly.

And with the latter, Round Group Betting markets deliver a bracket-based alternative to the exact round pick, giving bettors more room within their predictions while still requiring correct identification of the winner.

Floyd Mayweather Jr. – ‘Money’ (50-0, 27 KOs)

In his prime, Mayweather Jr. was a fighter unlike anyone else. And most likely, we’ll never see anyone do defensive boxing as well as ‘Money’ ever. 

Floyd Mayweather Jr. of Grand Rapids, Michigan, retired in August 2017 at 50-0 — the only man in history to retire from professional boxing with a perfect record at that number of fights. He won at super featherweight and then proceeded to dominate the lightweight, super lightweight, welterweight, and super welterweight divisions in a spectacular fashion. 

His defensive system, built around the Philly Shell (or shoulder roll), made him functionally impossible to hurt cleanly, which was evident in his high-profile bouts against even the deadliest offensive juggernauts. Throughout a span of 50 pro fights and 30 title bouts, Mayweather Jr. absorbed virtually no meaningful punishment. That’s hard to believe, but true…

Post-retirement, Mayweather Jr.’s career has been a series of commercially viable exhibitions. The American fought Don Moore in Abu Dhabi, Aaron Chalmers at the O2 in London, Deji Olatunji (TKO, R6), and had two chaotic affairs with John Gotti III in 2023 and 2024, the first of which ended in a no-contest. He’s 49 now, but Floyd’s instincts and reflexes remain exceptional. Against Gotti, he still seemed to have plenty left in the tank. The question is not whether he’ll be able to outbox Zambidis. It’s whether he chooses to entertain and leaves too many gaps in his famous defence.

Mike Zambidis – ‘Iron Mike’ (Kickboxing: 157-24, 87 KOs)

Mike “Iron” Zambidis is one of the most celebrated Greek combat sports athletes and one of the most decorated kickboxers ever to grace planet Earth. He amassed a legendary legacy in K-1 and full-contact kickboxing globally. 

Born to Albanian parents in Athens, Zambidis became one of the key figures who defined the K-1 MAX era (a lightweight-division offshoot of K-1). Greece’s Iron Mike collected 157 wins across multiple disciplines, with 87 of them coming in the form of KO/TKO. He held the K-1 MAX world championship multiple times and was one of the dominant forces in the <70kg kickboxing division for a very long time.

In boxing, however, Zambidis is a novice when compared to Mayweather Jr. Yet, so was Rico Verhoeven, but he stepped up to Oleksandr Usyk and, by official scorecards, was either tied or ahead by points before the stoppage in the 11th round. 

Despite the huge gap in boxing-specific credentials, Zambidis possesses lethal fists. During his prime, Iron Mike delivered overhand right finishes at the highest level of kickboxing repeatedly. The tactical question is whether he can land a clean right hand on a man who built a glorious legacy out of not being touched. The crowd at the OAKA will be doing everything in their power to give him the confidence to try.

Mike Zambidis does not have meaningful boxing bouts under his belt as of now.

FAQ

Is Mayweather Jr. vs Zambidis a Professional Fight?

Nope, this is a full-contact boxing exhibition. This means that while this won’t count towards either vet’s pro record, it’s still going to be a tough contest for 8 whole rounds at super welterweight (154 lbs).

Why is Floyd Mayweather Jr. Fighting Mike Zambidis?

“Money” has said that the Zambidis exhibition will be a great opportunity to sharpen his skills ahead of the much-anticipated rematch against Manny Pacquiao on 19 September 2026. That one is going to be a pro fight. Plus, the money might be good, as Zambidis is one of Greece’s most beloved sports figures, and the OAKA venue gives the event a scale and atmosphere that Mayweather exhibitions in smaller arenas cannot replicate. It should be a smaller version of Usyk vs Verhoeven.
