Overview
- Citing a September 22 Substack post, Burry said he added short positions “in some size” in Micron, Nebius, Palantir and the iShares Semiconductor ETF and called out heavy Nasdaq 100 concentration.
- Burry’s thesis rests on rising memory output outpacing demand, a view he supports with industry comments from Acer’s CEO that DDR4 shows oversupply while some high‑end parts remain tight.
- He flagged a report that China’s CXMT reached DDR5 yields above 90% and said that claim would strengthen his case if independently verified, but coverage describes that signal as unconfirmed.
- Markets split on the news: Palantir traded higher after the disclosure, Nebius fell, Micron moved little and the semiconductor ETF slipped, showing investors are divided about whether AI demand can absorb new capacity.
- Burry also bought value‑oriented long positions in QXO, Build‑A‑Bear, Sprouts, Birkenstock and MercadoLibre, and observers say the trade will hinge on memory supply verification and whether AI demand keeps growing.
