Hedge fund manager Bill Ackman of Pershing Square has acquired approximately $2.1B in new shares of Microsoft, capitalizing on the stock's recent price decline as a strategic entry point.
Pershing Square Capital Management has joined the ranks of Microsoft's (MSFT) major shareholders. Bill Ackman disclosed that he built approximately $2.1B worth of MSFT shares during a period of price weakness, consistent with Pershing Square's signature strategy of concentrated, high-conviction, long-term positions.
Buying the Dip — 'The Market Is Undervaluing MSFT'
Microsoft shares pulled back roughly 10–15% from their highs earlier this year amid concerns over AI monetization timelines and rising interest rate pressures. Ackman used this correction as his entry point, stating that 'Microsoft is a far stronger and more resilient business than investors currently appreciate.'
Microsoft is the company supplying the infrastructure for the AI era. The market has not yet fully priced in the value of this business.

Microsoft Identified as a Core AI Infrastructure Beneficiary
The core of Ackman's investment thesis rests on Azure cloud and Microsoft's investment in OpenAI. Through its multi-billion dollar commitment to OpenAI, Microsoft effectively serves as the exclusive backend infrastructure provider for AI services such as ChatGPT — positioning it to capture direct, structural upside from the growth of the enterprise AI market.
- Azure AI Services: Rapidly gaining share in the cloud AI market
- Copilot Subscription Expansion: Accelerating enterprise adoption of AI productivity tools
- GitHub Copilot: Dominant position in the developer productivity tools market
- Exclusive OpenAI Supply Agreement: Priority access to next-generation AI models
Pershing Square's High-Conviction Concentration Approach
Pershing Square typically maintains a concentrated portfolio of 10 to 15 positions. The $2.1B MSFT stake represents an estimated 10%+ allocation relative to Pershing Square's approximately $20B in assets under management — a weighting that signals exceptionally high conviction. Investors closely track Ackman's moves, given his track record of generating market attention through large-scale long positions and activist-driven catalysts.
