Michael Burry’s AI-linked shorts expand, targeting Oracle and Micron, plus Nebius Group

Michael Burry, the hedge fund investor made famous by the “Big Short,” is reportedly increasing his bearish exposure to the AI infrastructure buildout, adding to short positions that include Oracle and Micron Technology as well as Nebius Group, according to a market report published Thursday.

The report ties Burry’s latest moves to a broader skeptical view of the artificial intelligence boom, framing the investment thesis as one where the opportunity is obvious and the path to gains is straightforward. In the same discussion, the investor is quoted describing the setup as “shooting fish in a barrel,” a phrase that indicates conviction rather than a cautious, small bet.

Oracle is among the companies named in connection with the added short exposure. Oracle, which sells enterprise software and cloud-related services, has been treated by many investors as a potential beneficiary of enterprise demand for databases, applications, and infrastructure software. Burry’s reported move therefore stands out as a direct contrarian view on the idea that large AI spending will reliably translate into attractive outcomes for the companies positioned in the supply chain.

Micron Technology is also included in the alleged expansion of short positions. Micron is a major supplier of memory and storage technologies used in computing systems. Memory demand is often discussed in the context of AI training and inference workloads because those systems require high-performance memory and fast data handling. The report’s inclusion of Micron suggests Burry is betting against the durability, pricing power, or timing of that demand narrative.

Beyond Oracle and Micron, the report also mentions Nebius Group, a company tied to AI services and infrastructure efforts. While Nebius is not as widely followed as Oracle or Micron, the mention reflects the same theme: Burry appears to be targeting multiple points along the AI infrastructure ecosystem rather than a single stock.

The market article does not provide additional disclosure details such as the size of the positions, whether the trades were new or scaled within existing shorts, or how recently any filings were made. It also does not lay out specific financial metrics (such as revenue guidance, margins, cash flow, or balance-sheet leverage) that would support the bullish or bearish case for the named companies.

Burry’s stance matters for markets because his trades, even when based on private positions, can influence the sentiment around widely owned “picks and shovels” companies in the AI supply chain. For Oracle and Micron in particular, the reported increase in short exposure adds friction to the prevailing assumption that AI infrastructure spending automatically improves company fundamentals across the board.

Investors looking for what happens next will likely focus on whether Burry’s position changes prompt unusual trading activity, and whether Oracle, Micron, and Nebius provide any updated disclosures that address AI-related demand and capacity assumptions. The immediate reporting, however, centers on Burry’s reported portfolio action and his quoted characterization of the opportunity, not on company-specific new guidance.
