Michael Burry, best known for his prescient short on mortgage-backed securities ahead of the 2008 financial crisis, has reportedly taken a bearish position in Micron Technology (MU), according to MarketWatch. The trade is characterized as part of a broader skepticism toward the AI investment cycle, with memory chips seen as a leveraged proxy for AI infrastructure buildout.

Micron's recent fundamentals are hard to dismiss: FY2025 revenue came in at $37.4B, up nearly 49% year-over-year, with gross margins of 39.8% and diluted EPS of $7.59. The company has been a direct beneficiary of surging demand for HBM (high-bandwidth memory) used in AI accelerators, and that demand cycle appears intact near-term.

Burry's bet is a macro/cycle call more than a company-specific thesis — the argument being that memory is a notoriously cyclical industry and that AI-driven demand expectations are overstretched, setting up a sharp inventory correction when hyperscaler capex eventually normalizes or disappoints.

The tension is real: Micron's revenue trajectory is undeniably strong, but memory stocks have historically seen violent drawdowns when cycles turn, and Burry's track record on anticipating dislocations early — if not perfectly timed — commands some attention. The key variables to watch are hyperscaler capex guidance updates and any signs of HBM pricing softness in coming quarters.

Burry has been early (and wrong for extended periods) in prior trades before ultimately being right, so the timing risk here is significant. Micron's next earnings print and forward guidance will be a critical test of whether the AI memory upcycle has legs or is approaching saturation.
