Bill Ackman said his hedge fund Pershing Square will disclose a new stake in Microsoft, calling the stock’s price 'highly compelling.' The investment was also added as a core holding in Pershing Square USA, the closed-end fund that began trading last month. The move comes as Ackman has increased his technology exposure with prior buys in Meta, Amazon and Alphabet.

Key Points

  • Pershing Square will disclose a new position in Microsoft and has designated it a core holding in Pershing Square USA.
  • Ackman has been increasing tech exposure, with prior purchases in Meta Platforms, Amazon and Alphabet.
  • The development affects major technology and broader equity markets, particularly stocks tied to artificial intelligence competition.

May 15 - Bill Ackman said on Friday that his hedge fund Pershing Square will report a new position in Microsoft later in the day, describing the software giant as trading at a "highly compelling valuation." In a post on the social media platform X, Ackman added that Microsoft has been made a core holding in Pershing Square USA, the closed-end fund that launched on the NYSE last month.

The purchase of Microsoft is part of a broader pivot by Ackman toward larger technology names. Earlier this year, in February, he disclosed that Pershing had acquired shares of Meta Platforms on the view that the Facebook parent stands to benefit from artificial intelligence developments. Last year, the fund opened a position in Amazon, and it previously took a stake in Alphabet in late 2022.

Microsoft’s shares have declined by more than 15% so far this year, a slide that reflects investor concern about whether the company’s early lead in artificial intelligence is being eroded as competitors make advances. Ackman’s position signals that he regards the current price as an attractive entry point despite those market worries.

The addition of Microsoft to Pershing Square USA’s core holdings follows the fund’s recent debut on the NYSE. Ackman framed the purchase as driven by valuation considerations, writing that the company sits at a "highly compelling valuation" in his post.

Pershing’s actions come amid the manager’s growing appetite for the technology sector, with the fund having made fresh investments in several major tech platforms over the past year. Those moves include purchases in Meta Platforms, Amazon and Alphabet at different times, and now Microsoft has joined that list as a prominent holding.


Context and market reaction

The investment in Microsoft occurs against a backdrop of intense competition among large cloud and AI players. Investors have shown caution toward Microsoft this year given the stock’s drop exceeding 15 percent, even as market participants watch how Google and Amazon progress with their own AI initiatives.

What Pershing Square has said

  • Ackman announced the forthcoming disclosure of a Microsoft stake and described its valuation as "highly compelling."
  • Pershing Square USA, the new closed-end fund listed last month, has made Microsoft a core holding.
  • The fund’s recent activity reflects a broader increase in exposure to large technology companies, including earlier purchases of Meta Platforms, Amazon and Alphabet.

Given the facts Ackman shared publicly, the move highlights his continued interest in large-cap technology stocks and his view that current prices in at least some of those names present a buying opportunity.

Risks

  • Microsoft shares have fallen more than 15% year-to-date, reflecting investor concern about competitive pressure in AI - this impacts the technology sector and equity markets.
  • Investors worry that Microsoft’s early-mover advantage in AI could be eroding as competitors like Google and Amazon make progress - a competitive risk for cloud and AI-related businesses.
  • Pershing’s growing concentration in large tech names may raise exposure risk to sector-specific volatility for the fund and its closed-end vehicle.
