Key Takeaways
- • Bill Ackman's Pershing Square has accumulated a new stake in Microsoft, beginning in February 2026 after the stock declined following weak fiscal second-quarter earnings; the hedge fund called the position a "core holding" but did not disclose the stake size in initial announcements.
- • Pershing Square established its Microsoft position at a valuation of 21 times forward earnings, broadly in line with the market multiple and well below Microsoft's historical trading average, capitalizing on a >26% decline from the stock's July 2025 record high.
- • Ackman funded the Microsoft investment partly through the liquidation of Pershing Square's remaining Alphabet stake, clarifying in a separate statement that the Google sale was not a bearish bet but rather a capital reallocation decision given finite resources and current valuations.
- • Microsoft's stock decline was driven by investor concerns over Azure cloud growth sustainability and competitive threats to its AI strategy, particularly regarding the durability of returns on heavy AI capital investments; Ackman argues these concerns have been overblown by the market.
- • Supplemental disclosure indicates Pershing Square accumulated approximately $2.4 billion in Microsoft shares since February, positioning the software giant as a significant bet on AI and cloud computing fundamentals despite near-term investor skepticism.
Summary
Bill Ackman's Pershing Square Capital Management has disclosed a new stake in Microsoft, initiated in February 2026 during a broad equity market selloff in the software giant's shares. Ackman announced the investment via a lengthy public post on Friday ahead of his firm's quarterly 13F filing, characterizing the recent stock decline as a rare opportunity to acquire one of the world's most dominant technology franchises at an attractive valuation. The hedge fund manager established the position at a forward earnings multiple of 21 times, a valuation broadly in line with the overall market multiple but substantially below Microsoft's historical trading average, according to Ackman's disclosures.
Microsoft's stock has experienced significant pressure year-to-date, declining more than 26% from its July 2025 record high. The selloff has been driven principally by investor concerns regarding the sustainability of Azure cloud business growth and skepticism about whether Microsoft's substantial AI investments will deliver adequate returns relative to their capital intensity. Ackman's thesis directly counters this pessimism, arguing that markets have become overly concerned about the company's competitive positioning in artificial intelligence and have underestimated the durability of growth within its core cloud infrastructure business.
To fund the Microsoft acquisition, Pershing Square liquidated its remaining position in Alphabet, Google's parent company. In a clarifying statement issued on Saturday, Ackman emphasized that the Alphabet sale should not be interpreted as a bearish view on Google's long-term prospects, noting that Pershing Square remains "very bullish long term on Alphabet." Rather, Ackman framed the transaction as a prudent capital allocation decision, given Pershing Square's finite capital base and his assessment of current relative valuations between the two technology leaders.
While Ackman did not specify the precise size of the Microsoft stake in his initial disclosure, supplemental reporting indicates that Pershing Square accumulated approximately $2.4 billion in Microsoft shares since February, establishing the position as a material commitment within the hedge fund's portfolio. Following Ackman's public announcement on Friday morning, Microsoft shares rose 3% during intraday trading, suggesting market recognition of the endorsement from one of Wall Street's most prominent activist investors. The Pershing Square CEO's investment thesis underscores a contrarian positioning relative to broader market sentiment, betting that Microsoft's valuation discount relative to historical averages presents asymmetric upside as AI adoption and cloud infrastructure demand accelerate through the remainder of 2026 and beyond.
