Who Is This Person?

Michael James Burry is an American investor, hedge fund manager, and former physician specializing in neurology. He gained fame for predicting the 2008 subprime mortgage crisis and profiting from it through credit default swaps, as depicted in the film 'The Big Short.' Burry founded Scion Capital in 2000, which he later closed, and now manages Scion Asset Management. His Twitter account @michaeljburry, currently displaying the name 'Cassandra Unchained,' has a history of deletions and reactivations, including in 2021 and 2023, often following controversial posts or market predictions. As of December 2025, the account is active, with recent tweets focusing on market analyses, stock critiques (e.g., NVDA, TSLA, GME), historical investor letters, and warnings about bubbles and stock-based compensation. He shares cryptic charts, personal reflections, and rebuttals to media reports, maintaining a low-profile online presence outside Twitter.

Michael Burry is a highly credible figure in investment circles due to his prescient 2008 crisis prediction and disciplined value investing approach, backed by a track record of substantial returns at Scion. His expertise in financial analysis is well-established through professional affiliations and media portrayals. On Twitter, however, his influence is double-edged: posts drive engagement and discourse but are often vague, leading to misinterpretations and follower losses when acted upon impulsively. Verification and consistent bio/tweet themes affirm authenticity, with no evidence of impersonation. While controversies highlight risks of his bearish bias, his transparency in sharing historical documents and corrections bolsters overall credibility, though users should verify claims independently rather than treat tweets as direct advice.

What's Their Track Record?

Burry has a strong historical accuracy in major predictions, notably foreseeing and profiting from the 2008 financial crisis via bets against subprime mortgages, earning billions for investors. However, his record is mixed on shorter-term calls, including unsuccessful shorts on Tesla, Bitcoin, and broader markets, leading to account deletions after misses (e.g., 2021 Bitcoin inquiry, 2023 'sell' tweet). Fact-checks reveal occasional media misinterpretations of his 13F filings, which he corrects via tweets. Controversies include a 2021 spat with Elon Musk over Tesla criticism, where Musk called him a 'broken clock,' and reports of followers losing significant sums (e.g., $70 million cited in analyses) by mimicking his trades without context. No major fact-check retractions, but his cryptic style invites speculation and errors in reporting.
