Michael Burry warned that the artificial intelligence boom could direct enormous amounts of capital toward OpenAI and Anthropic, potentially destroying trillions of dollars after the companies go public. In posts on X dated September 29, 2026, Burry said markets should fall sharply to prevent their IPOs. OpenAI confidentially submitted a draft registration statement in June but has not set a listing date; CEO Sam Altman has said the company does not plan to go public in 2026. Reports say OpenAI is seeking a $30 billion funding round at an approximately $1.4 trillion valuation. Anthropic also confidentially filed in June, with reports pointing to a possible November listing and a valuation of about $2 trillion, although its timing and terms remain unsettled. Burry has repeatedly compared AI-stock enthusiasm with the late-1990s dot-com bubble. Anthropic reported $4.6 billion in 2025 revenue, operating losses exceeding $8 billion and hundreds of billions of dollars in future computing commitments.
