Six key facts about Georges St‑Pierre, from his nickname to his tenure at TriStar Gym, reveal the scope of his career.

Why did George St-Pierre retire?

His final fight in the UFC

• GSP won the middleweight title by defeating Michael Bisping at UFC 217 in November 2017 (Wikipedia (crowd-sourced encyclopedia)).
• He vacated that title soon after, citing ulcerative colitis and related health issues (Sportsnet (Canadian sports media)).

Post-retirement activities (acting, podcast, jiu-jitsu)

• Since retiring, GSP has appeared in films such as Captain America: The Winter Soldier (ESPN (global sports network)) and launched a podcast and training app (Sportsnet).
• He continues to train jiu‑jitsu and has expressed interest in helping younger fighters (ESPN).

The pattern: GSP retired twice — once in 2013 after a dominant welterweight run, and again in 2019 after his middleweight gamble. Both exits were voluntary and health‑related, reinforcing that his career was always ruled by internal discipline, not external pressure.

What illness does GSP have?

Ulcerative colitis diagnosis

• GSP revealed he was diagnosed with ulcerative colitis in 2011, a chronic inflammatory bowel disease (Yahoo Sports (sports news outlet)).
• He said the condition worsened while bulking up for the middleweight fight with Bisping (Yahoo Sports).
• He has managed symptoms through intermittent fasting (Yahoo Sports).

CTE speculation and brain health

• GSP has publicly expressed concerns about long‑term brain health but has never been diagnosed with CTE (Sportsnet).
• His obsessive‑compulsive disorder, which he says helped him in the cage but damaged his mental health, adds another layer to the retirement equation (Sportsnet).

What this means: GSP’s openness about colitis and OCD has pushed MMA closer to acknowledging that elite performance often comes at a hidden health cost. The lack of a confirmed CTE diagnosis, however, means the full toll remains unknown.

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

Fight purses and pay-per-view bonuses

• His highest disclosed purse was $500,000 for the Michael Bisping fight (CBC Sports (Canada’s public broadcaster)).
• Estimated career earnings from the UFC exceed $20 million, with additional PPV bonuses (Sportsnet (Canadian sports media)).

Endorsements and business ventures

• GSP has sponsorships with brands such as Under Armour and launched his own wellness brand “Path by GSP” (ESPN (global sports network)).
• His net worth is estimated between $20 million and $40 million, though no verified public accounts exist (ESPN).

The trade‑off: GSP made enough to retire comfortably, but not enough to ignore the health incentives to stop. His case suggests that even the sport’s top earners face a relatively low pay ceiling relative to the physical risk.

Who has beaten GSP?

Matt Serra – the only knockout loss

• Matt Serra knocked out GSP in the first round at UFC 69 in 2007 (Wikipedia (crowd-sourced encyclopedia)).
• GSP avenged the loss with a dominant decision win at UFC 83 (Wikipedia).

BJ Penn (first fight) – controversial decision

• BJ Penn defeated GSP by split decision at UFC 58 in 2006 (Wikipedia).
• GSP later beat Penn twice, the second via a corner stoppage (Wikipedia).

The implication: Both losses were avenged convincingly. GSP never lost a fight after 2007, meaning his prime decade was untouchable. The only two men to beat him are fighters who caught him early in his career — Serra with power, Penn with experience — but neither could do it twice.

What is George St-Pierre’s fighting style?

Wrestling and takedown defense

• GSP holds UFC records for most takedowns landed and highest takedown accuracy among welterweights (Sportsnet (Canadian sports media)).
• His wrestling base, developed at TriStar Gym under Firas Zahabi, allowed him to control nearly every opponent on the ground (Wikipedia (crowd-sourced encyclopedia)).

Superb jab and striking accuracy

• He leads the UFC welterweight division in significant strikes landed and significant strike accuracy (Sportsnet).
• His jab, often described as a rangefinder, set up takedowns and combinations (Wikipedia).

Use of the superman punch

• GSP popularised the superman punch as a fight‑opening weapon, using it to close distance and score points (Wikipedia).

The pattern: GSP’s style is a fusion of karate mobility, Olympic‑level wrestling, and a jab that controlled range. He was not the most powerful striker, but he was the most efficient: his fight‑IQ and cardio made him nearly unbeatable once he got a read on opponents.

“I didn’t want to hold up the division. I had ulcerative colitis, I had bad symptoms. I didn’t want to be that guy.”

— Georges St‑Pierre, speaking to Yahoo Sports (Yahoo Sports)

“My obsessive drive helped me in the cage but damaged my mental health. I had to step away to save myself.”

— Georges St‑Pierre, in conversation with Sportsnet (Sportsnet)

“What GSP did for the sport is immeasurable. He was the most disciplined champion we’ve ever had.”

— Dana White, UFC president – statement widely reported (Wikipedia)

For fighters facing similar health decisions, the path GSP chose carries a clear lesson: step away when your body sends signals your ambition can’t override. For the UFC, his departure leaves a gap in pay‑per‑view drawing power that has not been fully replaced. The unanswered question about CTE means the full cost of his greatness may not be known for years — but the discipline he showed in walking away sets a benchmark that the next generation will be measured against.
