Michael Burry, the investor known from the film The Big Short who previously warned about the 2008 mortgage market crisis, has expressed doubts about the sustainability of the artificial intelligence (AI) sector. In a recent Substack post — reported by Yahoo Finance — Burry argued that the continuation of the AI investment boom has become critical for the U.S. government.
What Burry argues
Burry contends that the AI narrative and associated infrastructure investments are currently holding together parts of the U.S. economy. He believes the Trump administration is aware of this and treats maintaining AI leadership as a national priority. At the same time, Burry questioned whether Washington has effective tools to prevent a potential downturn or financial crisis, saying very few such tools remain available to the government.
The Trump administration's approach
According to Burry's account, the administration is pushing faster integration of AI into government and national security functions, expansion of domestic computing infrastructure, and preservation of a technological edge over China. That agenda includes using advanced AI systems in military and intelligence contexts.
Burry's market moves
The report notes that Michael Burry has taken short positions in several prominent AI- and infrastructure-related companies and funds. Publicly disclosed positions include shorts in Oracle, Palantir, Nebius, Nvidia, the iShares Semiconductor ETF, Micron, and CoreWeave. Of these, Oracle, Palantir and Nebius represent his largest stakes.
Burry has long been skeptical that an investment cycle built on Nvidia chips, large cloud providers' data centers, and companies like OpenAI and Anthropic can sustainably support the broader economy without eventually triggering financial stress.
Why this matters
The warning is notable because major tech companies continue to invest record amounts in AI data centers, semiconductor makers and AI-infrastructure stocks have seen sharp gains, and companies such as Anthropic and OpenAI could undertake some of the largest IPOs in market history.
