Michael Burry, the investor who became a household name by betting against the US housing market before the 2008 financial crisis, is now putting serious money behind his conviction that the AI-fueled semiconductor rally has gone too far. In a Substack post dated June 30 to July 1, Burry revealed he has taken a direct short position in Micron Technology at approximately $1,051.87 per share.
The full scope of Burry’s bearish playbook
The Micron short is just the most visible piece of a broader bearish thesis Burry has been constructing over recent months. He has also refreshed his put options on the iShares Semiconductor ETF (SOXX), now targeting strikes in the low-to-mid $400s with March 2027 expiration dates. Given that SOXX has been trading between $560 and $640, those strikes imply Burry is positioning for a decline of roughly 30% to 41% from current levels.
SOXX has climbed approximately 65% in 2026 alone. From its previous lows, the ETF has roughly quadrupled.
Beyond Micron, Burry has disclosed short positions against Nvidia, Applied Materials, Tesla, and Caterpillar. On the long side, he maintains positions in PayPal and selected financial stocks, suggesting a deliberate rotation away from momentum-driven tech names and into sectors he views as more defensively positioned.
