‘Big Short’ investor Michael Burry warns of similarities between AI boom and dot-com bubble

Investor Michael Burry compared the current AI boom to the dot-com bubble, citing excessive venture capital funding and high-yield debt in unprofitable AI companies. He warned that Big Tech giants like Amazon, Google, Microsoft, and Meta plan to spend $700 billion on AI development this year, while private equity firms heavily invest in firms like OpenAI despite their lack of profitability.
Michael Burry, the investor famous for predicting the 2008 housing market collapse, has drawn parallels between today’s AI investment frenzy and the dot-com bubble of the late 1990s. In a subscriber-only post on his *Cassandra Unchained* Substack, Burry noted that technical and fundamental indicators suggest a speculative bubble, with AI companies receiving unprecedented funding despite lacking profitability. Burry highlighted that high-yield debt issuance in AI currently stands at 38%, comparable to the 40%-50% range seen during the dot-com era. He argued that the idea of today’s AI debt being ‘cleaner’ is misleading, as many funded companies are not yet profitable. Venture capital firms are pouring record sums into unprofitable ventures, he said, far exceeding the levels of 1999. Big Tech firms—Amazon, Google, Microsoft, and Meta—have collectively pledged $700 billion for AI development in 2024 alone. Private equity investments in AI startups, including OpenAI, have surged, further fueling concerns about speculative overvaluation. Burry’s warnings come amid his broader skepticism of the U.S. economy, including past critiques of Tesla’s valuation. Critics, such as Palantir CEO Alex Karp, have dismissed Burry’s warnings as overly pessimistic, particularly after he disclosed a bet against AI chip leader Nvidia. Despite skepticism, Burry’s track record—including his role in *The Big Short*—has lent weight to his latest cautions about AI market risks.
