    Pershing Square deploys $5B closed-end fund with 45% stake across MSFT, META, and UBER

    Question

    Pershing Square deploys $5B closed-end fund with 45% stake across MSFT, META, and UBER

    Direct answer

    Filings and disclosures confirm that Bill Ackman's newly launched $5 billion Pershing Square USA closed-end fund has deployed nearly all of its available cash reserves. 45% of the total vehicle is concentrated within three large-cap holdings: Microsoft, Meta Platforms, and Uber Technologies. The deployment follows earlier portfolio shifts where Pershing Square exited its equity stake in Alphabet during Q2 2026 while increasing its exposure to Meta Platforms by 20%. The fund manager cited corporate AI capabilities and network effect advantages as key allocation criteria.
