How Did Michael Burry Start His Investment Career?

He developed a website that attracted attention from individual investors and financial professionals. His work focused on identifying companies whose market prices differed from his estimates of their underlying value.
His analysis eventually attracted established investment managers.
In 2000, Burry launched Scion Capital with financial support from early investors, including Joel Greenblatt of Gotham Capital and interests associated with White Mountains Insurance Group.

What Is Scion Capital, and When Did Michael Burry Establish It?

The firm evaluated investment opportunities through company financial statements, market valuations, and assessments of business performance.
Burry concentrated on investments where his research suggested a substantial difference between price and value.

Scion Capital generated a cumulative return of approximately 489.34% after fees and expenses between November 1, 2000, and June 30, 2008.

| Scion Capital, net of fees | 489.34% |

Scion Capital’s return is net of fees. The S&P 500 comparison is approximately 2%, not an exact 2.1% measurement. Source: Michael Lewis, published in Vanity Fair.
These figures represent cumulative performance over nearly eight years, not annual returns or the return earned during 2008 alone.
Burry closed Scion Capital in 2008 and subsequently managed his personal investments.
How Did Michael Burry Predict the 2008 Financial Crisis?
Michael Burry anticipated the subprime mortgage crisis by examining the underlying loans in mortgage-backed securities and identifying growing risks of borrower defaults.
By 2005, he had concluded that rising mortgage payments, weak lending standards, and risky loan structures could cause substantial losses in the American housing market.
His research concentrated on three issues:
- Subprime mortgages: Loans issued to borrowers with weaker credit profiles.
- Adjustable-rate mortgages: Home loans whose interest rates could rise after initial introductory periods.
- Mortgage-backed securities: Financial products whose values depended on payments from collections of underlying mortgages.
Burry believed that many securities were priced without adequately reflecting the probability of widespread defaults.
He subsequently arranged investments designed to gain value if selected mortgage securities deteriorated.
What Investment Strategy Did Michael Burry Use During the Housing Crisis?
Burry used credit default swaps, or CDS contracts, to establish positions against mortgage-backed securities.
A credit default swap is a derivative contract that transfers specified credit risk between counterparties. Depending on its terms, the contract can provide a payment when an underlying borrower or security experiences a defined credit event.
Burry purchased protection against mortgage securities that he considered vulnerable.
He paid ongoing premiums to maintain these contracts. If the underlying securities deteriorated sufficiently, the contracts could increase in value.
The strategy involved substantial costs and uncertainty because the mortgage market remained strong for a period after Burry identified the risks.
How Much Did Michael Burry Make From the 2008 Financial Crisis?
Michael Burry made approximately $100 million personally, while his investors earned about $725 million, according to Michael Lewis’s account of the mortgage-market trade.
| Category | Reported profit |
|---|---|
| Burry’s personal profit | $100 million |
| Investor profit | $725 million |
These amounts are historical profits associated with his mortgage-market investments. They do not represent his current net worth or the current value of his portfolio.
What Is Michael Burry’s Net Worth in 2026?
Michael Burry’s exact net worth in 2026 is not publicly verified. Some financial biography websites publish estimates, but no comprehensive, independently audited disclosure establishes his current personal wealth.
His financial resources are associated with several activities:
- Profits from Scion Capital.
- Personal investments in publicly traded securities.
- Investment gains and losses from later market positions.
- Potential income from his financial publication.
His reported $100 million personal profit from the mortgage-market trade provides historical context but cannot establish his wealth in 2026.
Net worth includes assets minus liabilities. Without complete information about his private investments, debts, taxes, and other holdings, a precise current figure would be speculative.
What Happened to Scion Asset Management?
Scion Asset Management was Michael Burry’s later investment management firm, established after the closure of Scion Capital.
The firm began operating in 2013 and became known for investments in publicly traded companies and options.
Its disclosed positions attracted financial media attention because Burry had previously identified risks in the mortgage market.
However, in November 2025, Burry moved to close the firm and return outside investors’ capital.
According to Reuters, a letter dated October 27, 2025, communicated the intention to liquidate the funds, subject to a limited reserve for tax and audit requirements.
The US Securities and Exchange Commission subsequently listed Scion Asset Management’s registration as terminated, effective November 10, 2025.
Did Michael Burry Retire After Closing His Hedge Fund?
No. Michael Burry continued participating in financial markets after deregistering Scion Asset Management.
In November 2025, he told Bloomberg that he remained active in markets. He explained that the firm’s more recent operations had primarily involved friends and family rather than a broad base of outside investors.
He also launched a financial newsletter, Cassandra Unchained, to publish investment research and market commentary.
What Is Michael Burry Doing in 2026?
As of October 2026, Michael Burry publishes financial research and investment commentary through his Substack newsletter, Cassandra Unchained.
His publication covers company valuations, market conditions, potential financial bubbles, and individual investment opportunities.
Recent subjects include:
- Artificial intelligence infrastructure spending.
- Technology company valuations.
- Corporate accounting and equipment depreciation.
- Value investing opportunities.
- Fannie Mae and Freddie Mac.
- International equities and market conditions.
His published articles on October 1, 8, and 11, 2026, discussed subjects including GPU depreciation, AI cloud infrastructure, and investment opportunities in Hong Kong stocks.
Why Has Michael Burry Criticized AI Stock Valuations?
Burry has questioned whether some technology companies’ valuations and accounting assumptions adequately reflect the costs and risks of artificial intelligence infrastructure investment.
One concern involves depreciation. Companies spread the accounting cost of equipment over its estimated useful life. Longer estimated useful lives generally reduce annual depreciation expenses, increasing reported profit relative to shorter estimates.
Burry has argued that certain assumptions about AI computing equipment deserve closer examination.
These statements represent his investment analysis, not established proof that the AI industry is experiencing a market bubble.
His commentary has prompted disagreement among market participants, including executives of companies whose valuations he has questioned.
What Is Michael Burry’s Investment Philosophy?
Michael Burry’s investment philosophy centers on value investing, independent research, and identifying securities whose market prices differ from their estimated intrinsic values.
His approach reflects concepts associated with investors and financial researchers such as Benjamin Graham and David Dodd.
What Are the Main Principles of Michael Burry’s Investing Strategy?
Five principles frequently appear in Burry’s documented investment approach:
- Fundamental analysis: Examining financial statements, assets, liabilities, and business performance.
- Valuation discipline: Comparing security prices with estimates of underlying economic value.
- Independent research: Investigating financial information rather than relying only on market consensus.
- Risk assessment: Studying possible losses, leverage, and business vulnerabilities.
- Contrarian positioning: Purchasing or selling securities when detailed analysis supports a view that differs from prevailing expectations.
These principles do not eliminate investment risk. Market prices can remain disconnected from estimated value, and even well-researched positions can produce losses.
In his 2011 Vanderbilt lecture, Burry explained how his observations of government policies, economic incentives, and financial markets shaped his analysis.
Who Played Michael Burry in The Big Short?
