Michael Burry, the famous “Big Short” investor, has initiated a new short position against semiconductor giant Micron Technology Inc. (NASDAQ:MU), declaring the artificial intelligence darling a structural “destroyer of capital” caught in a highly psychological market bubble.

Chasing ‘Bubble Peaks’

Burry disclosed the thesis on his private Substack, expanding his broader bearish campaign against overextended AI infrastructure equities.

Despite Micron’s massive gains over the past year, driven by aggressive artificial intelligence demand, Burry revealed he shorted the stock “even though it was down a good amount,” as of Thursday, firmly betting that the current semiconductor frenzy is unsustainably overheated.

He highlighted that the stock’s extension over its 200-day moving average has “never been as extended as in 2026, not even during the dot-com peak,” framing the chip rally as a late-stage phenomenon typically seen near “bubble peaks.”
