Michael Burry Expands AI Short Bets, Adding Micron, Nvidia Shorts at Specific Price Points

According to Michael Burry's Substack post on July 26, the Big Short investor expanded short positions in semiconductor stocks, adding Micron (MU) at $933.86 per share, Nvidia (NVDA) at $210.28, and increasing Semiconductor ETF (SOXX) shorts at $535.83, while initiating a new short position in Caterpillar (CAT).

Burry argued that Nvidia's large order pipeline does not reflect genuine end-user demand but rather represents a financing illusion created through off-balance-sheet arrangements that artificially inflate AI infrastructure investments. He cited the 2026 Bank for International Settlements annual report to support his thesis that the semiconductor sector faces systemic overvaluation driven by circular financing rather than organic demand.
