Michael Burry reignites AI infrastructure skepticism with fresh short bets on Nvidia, Micron and AMD

Michael Burry, the hedge-fund investor whose bets helped popularize “The Big Short,” is pointing to the artificial-intelligence infrastructure trade as a setup he believes can unwind. In a new market report published by The Motley Fool and carried by Yahoo Finance’s markets coverage, Burry is described as revealing additional bearish positions tied to some of the best-known companies in AI computing and memory.

According to the report, Burry’s latest move centers on shorting Nvidia. Nvidia’s graphics processing units and accelerated computing platforms are widely used to train and run AI models, and the company has been a focal point for investors trying to capture growth from data-center AI spending.

The same coverage also frames Burry’s view as extending beyond Nvidia. He is described as making a bet against Micron Technology, a major supplier of memory used in data centers, and also taking aim at AMD, another key chip designer whose processors can be used across servers and AI systems. Taken together, the positions are presented as a broad skepticism toward the whole “AI infrastructure boom,” not just one company.

Separate Yahoo Finance markets reporting described Burry as adding a new short position against Micron, positioning it alongside earlier bearish stakes that already included Nvidia and Applied Materials. Applied Materials is an equipment maker that sells tools used in semiconductor manufacturing, which means it is indirectly exposed to the pace and scale of chip production for AI demand.

Burry’s approach, as reflected in these reports, is less about arguing that AI adoption will stop and more about questioning whether the market’s pricing for the enablers is too optimistic. In recent years, semiconductors have attracted heavy capital flows tied to AI, from data-center compute to networking and memory, which can amplify both upside in good times and downside when expectations reset.

For the companies involved, the practical risk in a short-bet narrative is reputational and sentiment related, not an immediate operating change. Short positions are private trading activity and typically do not require the targeted companies to disclose anything. Still, when a widely followed investor highlights bearish stakes in high-profile names, it can feed debate about valuation, demand durability, and whether supply-chain beneficiaries are being priced for uninterrupted growth.

What is not clear from the publicly circulated summaries is the size, timing, and structure of the positions, including whether they were initiated, increased, or adjusted through derivatives. The reporting also does not provide the specific performance metrics or thresholds Burry would be watching, beyond the general theme that he expects the AI hardware cycle to face a challenge.

Investors may look next for additional transparency from the investor’s filings, if any, and for company updates that address demand and pricing across data-center and memory end markets. For the sector, the larger question is whether “AI infrastructure” multiples can be sustained as the industry moves from early buildouts toward broader deployments, and whether market expectations for each link in the chain prove durable. No investment advice is implied by these moves or by any coverage of them.
