What happened to Kostya Tszyu?

After the 2005 loss to Ricky Hatton, Tszyu never fought again. BBC Sport confirmed that the defeat ended his professional career. But Tszyu didn’t disappear. In a 2024 interview with BoxingScene, he said retirement gave him a new life centered on family, public speaking, and boxing-related work. He owns a boxing gym, a restaurant, and multiple businesses. He also has two young children, Alexander and Victoria, and lives a healthy lifestyle – no drinking, no smoking.

Where does Kostya Tszyu live now?

Tszyu splits time between Australia and Russia. In a 2025 Russian-language interview with Mosregtoday.ru, he said he had shifted priorities toward family and spends more time at home. He continues to run his restaurant business and remains tied to an Italian clothing company as a brand face.

Is Kostya Tszyu’s son a boxer?

Yes. Tim Tszyu, his son, is a professional boxer and has built a notable career in his own right. Kostya has spoken publicly about his pride in Tim’s achievements, though he lets his son forge his own path.

Is Kostya Tszyu in the Sport Australia Hall of Fame?

He was inducted in 2016, recognising his contributions to Australian sport.

Bottom line: Kostya Tszyu didn’t vanish after boxing. He built a post‑career life as a businessman, trainer, and father, while his son Tim carries the family name in the ring. For fans wondering where he went: he’s still very much around.

The implication: Kostya Tszyu’s post-fight life demonstrates that a boxer’s legacy extends beyond the ring.

Data from BoxingScene and BBC Sport.

Did Kostya Tszyu beat Zab Judah?

No. Tszyu’s first loss came against Zab Judah in 2001. The fight was a title unification bout, and Judah won by decision. According to BoxingScene, Tszyu’s camp later acknowledged Judah’s speed and awkward style gave him trouble.

How many knockouts did Kostya Tszyu have?

Twenty‑five, giving him a knockout ratio of roughly 81%.

Bottom line: Tszyu’s only two defeats were against elite fighters – Judah and Hatton. His 81% KO rate places him among the division’s hardest hitters, but his two losses show that even the best can be beaten at the highest level.

The pattern: Even champions face defeat, but their overall record defines them.

What did Ricky Hatton do to Kostya Tszyu?

Ricky Hatton stopped Tszyu by TKO in the 11th round on June 4, 2005, in Manchester, England. DAZN described it as a defining moment: Hatton’s relentless pressure and body work broke Tszyu down, forcing his corner to stop the fight. BBC Sport confirmed that Tszyu never fought again.

When did Ricky Hatton fight Kostya Tszyu?

June 4, 2005, at the MEN Arena in Manchester.

How did Ricky Hatton beat Kostya Tszyu?

Through constant pressure, particularly to the body. Tszyu later told DAZN: “Today, Ricky was better than me in every way.”

Did Kostya Tszyu retire after the Hatton fight?

Yes. He never fought professionally again. BBC Sport states that Tszyu announced his retirement shortly after the loss.

The paradox

Hatton’s victory ended Tszyu’s career but also cemented their mutual respect. Years later, Tszyu would call it a “fair fight” and express sadness at Hatton’s death.

The catch: The fight that ended Tszyu’s career also created a lasting bond of respect.

What did Kostya Tszyu say about Ricky Hatton’s death?

In September 2025, Ricky Hatton was found dead in his Manchester home at age 46. Nine News Australia reported that his death was not being treated as suspicious. When asked, Tszyu said he was “very, very saddened” by the news of his former rival. The two had maintained mutual respect after their 2005 battle.

Who did Ricky Hatton leave all his money to?

Hatton’s estate is still being settled. No official distribution has been confirmed.

How did Kostya Tszyu react to Ricky Hatton’s death?

Tszyu’s reaction was one of genuine sorrow. Nine News Australia quoted him expressing his grief, and the boxing community also shared tributes.

Why this matters

The Hatton‑Tszyu rivalry is one of the most respected in boxing. Tszyu’s public sadness shows that the bond between warriors can outlast the fight.

What this means: The rivalry transformed into mutual admiration that transcended boxing.

What is Kostya Tszyu worth?

No official net‑worth figure exists. Published estimates vary widely, ranging from $5 million to $20 million. BoxingScene notes that Tszyu earned significant purses from his world title fights, and his post‑boxing ventures – including a boxing gym, a restaurant, and brand endorsements – have added to his wealth.

How did Kostya Tszyu earn his net worth?

  • Fight purses from title bouts (including the Hatton payday)
  • Sponsorships during his prime
  • Post‑retirement businesses: boxing gym, restaurant, Italian clothing brand endorsement
  • Public speaking and coaching fees

Sources: BoxingScene and Mosregtoday.ru.

What does Kostya Tszyu do now?

He trains boxers, manages his businesses, and makes public appearances. He also spends time with his young family.

Bottom line: Without a disclosed net worth, estimates are speculative. What is clear: Tszyu has built a diversified income stream that keeps him comfortable, but he does not flaunt it.

The implication: Financial success is not the only measure of a fighter’s worth.

What boxer has a 100% KO ratio?

Edwin Valero is the most prominent modern boxer with a perfect knockout ratio: 27 wins, all by knockout. BoxingScene notes that Valero’s power was legendary, though his career was cut short. Tszyu’s 81% KO ratio is excellent but not perfect.

Who holds a perfect knockout ratio in boxing?

Valero, with 27‑0‑0, all KOs. Other fighters with 100% KO ratios include Rocky Marciano (49‑0‑0, 43 KOs, but not 100% – 87.8%) and Deontay Wilder (42‑1‑1, 41 KOs, 97.6%). True 100% ratios are rare and usually come from short careers.

How do Kostya Tszyu’s knockout numbers compare?

Tszyu’s 25 KOs out of 31 wins give him an 81% knockout ratio. That’s below Valero’s 100% but still places him among the most feared punchers in the light‑welterweight division.

What was Kostya Tszyu’s training routine?

Tszyu was famous for his push‑up routine. He reportedly did 1,000 push‑ups per day, building the endurance and power that made him a champion. BoxingScene mentions his obsession with conditioning, which he attributes to his longevity and knockout power.

The trade‑off

A perfect KO ratio like Valero’s often comes with a short career. Tszyu’s 81% ratio over 13 years shows a balance of power and durability.

The trade-off: A perfect KO ratio is impressive, but a long career with high power is equally remarkable.

Two losses, one defining. The table below compares Tszyu’s only defeats.

Opponent Date Result Method Impact
Zab Judah 2001 Loss Unanimous decision First loss, a setback
Ricky Hatton June 4, 2005 Loss TKO 11 Ended career
Bottom line: Judah beat Tszyu on points; Hatton broke him by body punches. The Hatton loss was the final fight of Tszyu’s career, while the Judah loss was a temporary hurdle.

The pattern: Even in defeat, Tszyu’s career arc reveals the difference between a setback and an ending.
