Key Takeaways

• Michael Burry revealed short positions targeting Micron, Nvidia, Tesla, Applied Materials, Caterpillar, and a major semiconductor ETF
• His Micron short was initiated around $1,051.87, highlighting the stock’s extreme distance from its 200-day moving average—a gap unseen since 1984
• Burry characterized the AI investment trend as “mass addiction” and warned that “the end is nigh”
• Meanwhile, Micron delivered stunning results with revenue jumping 346% annually to $41.5 billion alongside record profitability metrics
• The core of Burry’s position centers on valuation extremes and market timing rather than fundamental business deterioration

Michael Burry, renowned for correctly forecasting the 2008 subprime mortgage collapse, has initiated significant short positions against leading artificial intelligence and semiconductor companies.

Beginning June 30 through a sequence of Substack publications, Burry revealed bearish bets on Nvidia, Tesla, Applied Materials, Caterpillar, and the iShares Semiconductor ETF. The following day, July 1, he disclosed a short position on Micron established at approximately $1,052 per share.

In his post, Burry characterized “the AI narrative is nothing more than mass addiction.” He punctuated his bearish stance with an ominous reference to the Joker from the original 1989 Batman movie: “The end is nigh. Dancing with the devil in the pale moon light.”

He shared Bloomberg data visualizations demonstrating AI chip manufacturers significantly outpacing both cloud infrastructure providers investing in AI and the wider ecosystem of AI-related companies. An additional chart illustrated the Philadelphia Semiconductor Index hovering near peak levels within its 15-year valuation spectrum.

The Bear Case Against Micron

Burry’s most pointed critique targeted Micron. He highlighted the stock’s history of experiencing 34 separate declines exceeding 30% throughout the past 42 years, labeling it exceptionally cyclical.

He calculated Micron’s median return on invested capital at merely 4% with median return on equity at 7%, describing these metrics as “frankly terrible.” According to Burry, Micron actually destroys shareholder value approximately once every three quarters.

Regarding Micron’s high-bandwidth memory products driving AI-related demand, Burry downplayed their significance as “just another in a very long series” of offerings without sustainable competitive positioning.

He attributed the stock’s recent price acceleration to “fear of missing out, greater fool theory, and public commitment bias.”

Examining Micron’s Financial Performance

The latest quarterly financial data from Micron tells a substantially different story than Burry‘s historical analysis suggests.

For the quarter concluded in May 2026, Micron reported revenue of $41.5 billion, representing a remarkable 346% increase year-over-year. Gross margin expanded dramatically to 84.6% from 37.7% in the comparable prior-year period.

Net income surged to $28.2 billion versus $1.9 billion twelve months earlier. Free cash flow reached $17.6 billion, a dramatic improvement from $1.7 billion in the year-ago quarter.

During the June 24 earnings conference call, Chief Business Officer Sumit Sadana indicated that customer appetite for memory products “well above our ability to supply” across virtually all product lines extending through 2028.

Micron shares have delivered approximately 1,000% returns over the trailing three-year period and have climbed roughly 260% during 2026 alone.

Currently trading near $976 per share, Micron carries a price-to-earnings multiple of approximately 22. Company leadership projected roughly $50 billion in revenue for the upcoming quarter.

Burry’s thesis doesn’t argue that Micron’s business is presently deteriorating. Rather, he’s wagering that the stock’s valuation has extended beyond sustainable levels and that the cyclical nature of the memory market will inevitably reassert itself.
