Fund manager Michael Burry increased short positions on Micron and Nvidia while maintaining bets on Tesla and Palantir, as disclosed in recent filings. Separately, Nvidia, Microsoft, and Palantir are reported to be leading industry pushback against new AI restrictions.

Palantir is mentioned in two distinct narratives: it remains a holding in Burry's portfolio, and it is part of a coalition with Nvidia and Microsoft challenging upcoming AI regulations. The outcome of the regulatory pushback could affect the operating environment for firms in the AI sector, including Palantir. The short positions on Nvidia and Micron reported by Burry relate to those specific names and may reflect broader positioning in the semiconductor and AI ecosystem, but the direct linkage to Palantir's valuation is not specified in the sources.
