“Big Short” investor Michael Burry discloses new short bets that include Nvidia, Tesla and Micron

Michael Burry, the hedge-fund investor made famous by the 2008 housing-market collapse, disclosed fresh bearish positions that include Nvidia alongside Tesla and Micron. Reporting on Burry’s latest activity pointed to a pair of Substack posts in which he said he was putting money to work against parts of what he views as a stretched, AI-led stock market trade.

According to published accounts of those posts, Burry disclosed short positions and also laid out entry prices for his trades. One report said that in a June 30 post he revealed shorts in Nvidia (NASDAQ: NVDA), Tesla (NASDAQ: TSLA), Applied Materials (NASDAQ: AMAT), Caterpillar (NYSE: CAT), and the iShares Semiconductor ETF (NASDAQ: SOXX). Two days later, he added a short against Micron Technology (NASDAQ: MU), reportedly entered near $1,052 per share.

The framing in these reports is that Burry is not necessarily arguing the underlying businesses are collapsing, but that the market has pushed valuations and expectations to extremes. One summary said his thesis focuses on the degree to which “the AI boom” may have encouraged investors to overlook what he sees as a repeatable “memory cycle” in the semiconductor sector, an idea tied to DRAM and related memory pricing dynamics.

For Micron specifically, one account said Burry argued the stock was trading further above its 200-day moving average than at any point since 1984, a period that includes the dot-com peak. That same account also said he pointed to the long history of large drawdowns in Micron shares, describing what he sees as repeated episodes of steep declines over several decades.

Nvidia is at the center of the current AI buildout, selling accelerated computing chips and related systems that are widely used to train and run machine-learning models. Nvidia’s stock has been viewed by market participants as a proxy for enterprise and cloud spending on AI infrastructure. Even without new operational details in the short-bet disclosure itself, the appearance of Nvidia on Burry’s short list is likely to catch attention because the company is among the best-known beneficiaries of the AI capex cycle.

Burry’s other disclosed targets in the same set of trades further suggest a theme aimed at the broader “AI trade,” rather than a single-company issue. Reporting said his short list also included chipmaking equipment vendor Applied Materials, industrial-equipment maker Caterpillar, and a semiconductor index ETF, with Tesla also singled out. That mix implies a view that crowded positioning and valuation expectations, not just fundamentals, are part of the risk.

What has not been clearly disclosed in the available reporting is the full mechanics of each trade, including the exact option contracts, strike prices, expiration dates, portfolio sizing, or how the entry-price levels were calculated. The published summaries also do not provide company-specific new guidance from Nvidia, Tesla, Micron, or the other names. As a result, investors and analysts will still be left to interpret the move primarily as a announcement of sentiment and valuation risk rather than a reaction to a newly revealed fundamental problem.
