Key facts

medical education

Burry studied at UCLA, entered Vanderbilt’s medical school in 1993 and earned his MD in 1997 before pursuing residency training at Stanford.⁠[1][2][3]

leaving medicine and founding Scion Capital

During residency he ran an investment website and wrote for MSN Money. He left medicine and founded Scion Capital in 2000; Gotham Capital and White Mountain Insurance subsequently invested in its management company.⁠[3][2]

building the subprime short

In his 2011 account, mortgage disclosures led Burry to conclude that loose lending was unsustainable. He agreed initial trades with Deutsche Bank in May 2005 and executed them in early June, buying credit default swaps on subordinated subprime mortgage securities.⁠[1]

investor pressure and the payoff

Burry recalled that valuation and redemption pressure forced sales of some corporate-credit shorts in 2006; retained mortgage positions began paying off in 2007. Vanderbilt later reported a 489.34% ultimate fund return and $750 million returned to investors; that distribution is not a net-profit figure.⁠[1][2]

closing Scion Capital

Burry closed Scion Capital in 2008 and focused mainly on personal investments for several years.⁠[2]

returning to fund management

market-breadth comparison

In a public X post, Burry recalled indices rising in early 2000 while many individual stocks were already in bear markets, characterizing the divergence as denial. The comparison continued his criticism of AI-related market structure.⁠[11]
