Has GSP ever lost?

Yes — twice. The first was a disqualification loss to Matt Hughes in 2002 when an illegal strike ended the fight prematurely. The second was the famous 2007 TKO loss to Matt Serra at UFC 69, a moment that shook the MMA world. Both losses were later avenged: St-Pierre defeated Hughes again and beat Serra by decision in 2008 to reclaim the welterweight title (BBN Times).

Who defeated Georges St-Pierre?

  • Matt Hughes – DQ loss, 2002 (illegal strike)
  • Matt Serra – TKO, 2007 (UFC 69)

What is GSP’s loss record?

Two defeats against 26 wins. All other fights ended with St-Pierre raising his hand. The pattern: he never lost a fight after avenging a prior defeat.

The paradox

St-Pierre’s two losses are the only blemishes on a record that includes nine consecutive title defenses — the second-longest combined title streak in UFC history at 2,204 days (Wikipedia record data).

Bottom line: GSP’s two losses defined him as a champion who learned and adapted. For fighters studying his career, the lesson is that even the best can stumble — and recovery is what separates legends from contenders.

What illness does GSP have?

St-Pierre has spoken publicly about two health conditions that shaped his career: obsessive-compulsive disorder (OCD) and ulcerative colitis, an inflammatory bowel disease (Sportsnet, Canadian sports news outlet).

Does GSP have OCD?

Yes. In 2014, he revealed his diagnosis, describing how his obsessive tendencies fueled the meticulous training that made him dominant — but also corroded his mental health. “It was an asset in my career but harmful to my mental health,” he told Sportsnet. The condition played a role in his decision to step away after the Johny Hendricks fight in 2013.

What is ulcerative colitis?

Ulcerative colitis is a chronic inflammatory bowel disease that causes inflammation and ulcers in the digestive tract. St-Pierre’s battle with it contributed to his physical exhaustion and his choice to vacate the middleweight title in 2017. He has not disclosed the severity of his symptoms publicly (Wikipedia biographical summary).

Why this matters

St-Pierre’s openness about OCD and colitis destigmatizes mental health issues in combat sports. Athletes at the top level face pressures that can trigger or worsen such conditions — and his career shows that seeking help is not weakness but strategy.

The implication: GSP’s transparency about his health issues has helped normalize discussions of mental health in combat sports.

Why did GSP retire so early?

St-Pierre retired twice, both times while still holding a championship belt. The first retirement came in December 2013, days after a controversial split-decision win over Johny Hendricks at UFC 167. He cited exhaustion, the toll of ulcerative colitis, and ongoing contract disputes with the UFC (Sportsnet). He later admitted he was “in some kind of depression” at the time (Wikipedia biographical entry).

Why did he vacate the middleweight belt?

After returning in 2017 to defeat Michael Bisping for the middleweight title, St-Pierre vacated the belt within 34 days, citing a recurrence of ulcerative colitis symptoms. He said the weight cut and training regimen were unsustainable given his health.

What caused his first retirement?

A combination of physical depletion, mental health struggles (OCD and depression), and a fractured relationship with the UFC. He walked away from a welterweight title he had defended nine times.

The catch

St-Pierre’s early retirements were not about lack of skill — they were about preserving a body and mind that he had pushed to the limit. For any athlete with chronic health conditions, his story is a cautionary tale about the cost of perfectionism.

The pattern: his exits were strategic decisions to protect long-term health, not a reflection of competitive decline.

How much money did George St. Pierre make in the UFC?

Estimates vary widely, but St-Pierre’s net worth is reported between $20 million and $30 million. Celebrity Net Worth and the Times of India peg it at $20 million as of 2025, while Players Bio and Tuko estimate $30 million. The largest single payday was reportedly $2.4 million for the Michael Bisping fight in 2017 (Times of India).

What is GSP’s net worth?

Estimates converge in the $20–30 million range. Sources like BBN Times note he earned over $10 million from UFC fights alone, with PPV bonuses and sponsorships adding substantial income.

What were his biggest paydays?

  • Michael Bisping (2017): $2.4 million (reported)
  • Nick Diaz (2013): $2 million (estimated base + PPV)
  • Johny Hendricks (2013): $1.8 million (estimated base + PPV)

Bottom line: St-Pierre’s financial legacy is solid but not stratospheric by modern athlete standards. His net worth reflects a career built on consistent championship paydays rather than crossover marketing deals. For investors or analysts tracking MMA finances, GSP demonstrates that peak earning potential in the UFC requires both title longevity and PPV draw — he had both.

What UFC fighter turned to OnlyFans?

Several UFC fighters have joined OnlyFans, including Paige VanZant, Rachael Ostovich, and Alan Belcher. Confusion sometimes arises because GSP’s name is mentioned in rumors; however, St-Pierre has never participated on that platform. He remains a UFC Hall of Famer focused on acting and martial arts education (Wikipedia biography).

Did GSP join OnlyFans?

No. This appears to be a persistent internet rumor with no evidence. GSP’s official social media accounts show no involvement.

Who among UFC fighters joined OnlyFans?

  • Paige VanZant – former strawweight, joined in 2020
  • Rachael Ostovich – flyweight, joined in 2021
  • Alan Belcher – middleweight, joined in 2021
What to watch

The OnlyFans rumor highlights how quickly misinformation spreads in sports media. For journalists and fans, verifying claims through official channels is essential before repeating them.

The catch: this rumor persists even though GSP has never shown interest in such platforms, illustrating how internet speculation can attach to high-profile figures without basis.

Career timeline

From his amateur beginnings to his final fight, the chronology shows a path of constant escalation — and two deliberate stops.

  • 2002 – Professional MMA debut; loss to Matt Hughes (DQ, illegal strike) (Wikipedia)
  • 2006 – Wins UFC Interim Welterweight Championship; defeats Matt Hughes for unified title (BBN Times)
  • 2007 – Loses welterweight title to Matt Serra (TKO) (Wikipedia)
  • 2008 – Avenges loss to Serra; regains welterweight title (BBN Times)
  • 2008–2013 – Nine successful title defenses, including wins over BJ Penn, Jon Fitch, and Carlos Condit (Wikipedia)
  • 2013 – Defeats Johny Hendricks; vacates title and takes break citing health issues (ulcerative colitis, OCD) (Sportsnet)
  • 2017 – Returns to defeat Michael Bisping for middleweight title; vacates due to health and contractual issues (MMA Fighting)
  • 2019 – Officially announces retirement from MMA (MMA Fighting)

The pattern: each pause in his career came after a championship victory, suggesting he walked away at peaks to preserve his legacy and health.

Clarity section: confirmed vs. unclear

Confirmed facts

  • GSP has two professional losses (Matt Hughes DQ, Matt Serra TKO) (BBN Times)
  • GSP has been open about living with OCD and ulcerative colitis (Sportsnet)
  • He retired twice, in 2013 and 2019 (MMA Fighting)
  • He held the welterweight title for 2,204 consecutive days (Wikipedia)

What’s unclear

  • Exact net worth figures vary by source ($20–30 million)
  • He has not disclosed contractual details behind his 2013 break
  • Severity of his ulcerative colitis during active career not fully documented
  • Whether his OCD medication or therapy was used during his fighting years is unknown

The implication: while many facts are solid, gaps remain in financial disclosure and health specifics that require further verification.

Summary

Georges St-Pierre’s career is a rare case study in how controlled aggression and obsessive preparation can produce perfection — and how exactly those same traits can force a champion to walk away. For the next generation of fighters, the lesson is not about routines or weight cuts. It’s about knowing when the price of greatness becomes too high. For MMA fans and analysts, the choice is clear: appreciate the legacy, but never forget the human cost behind the record.
