- Shares climbed approximately 3.7% by midday Friday, reaching as high as 4.1%, even as the S&P 500 dropped 1.2%
- Chris Hohn’s TCI Fund Management liquidated nearly all of its $8 billion position, expressing concerns about AI competition risks

Shares of Microsoft (MSFT) surged on Friday following the revelation that prominent investor Bill Ackman’s Pershing Square Capital Management established the position as a “core holding” — simultaneously exiting its entire stake in Alphabet.
By midday Eastern Time, the stock had advanced 3.76% to $424.81. Earlier in the session, shares peaked at $426.44, marking a 4.1% intraday gain. This upward movement contrasted sharply with broader market trends, as the S&P 500 declined 1.2% and the Nasdaq fell 1.4%.
In an extensive 887-word social media post Friday morning, Ackman explained his rationale, describing Microsoft’s current valuation as “highly compelling” following a period of sustained selling pressure that has pushed the stock down 13% year-to-date in 2026 and 22% below its record high.
The investment represents a complete portfolio rotation — Pershing liquidated its Alphabet holdings entirely to finance the Microsoft acquisition. Ackman highlighted the company’s cloud infrastructure operations and its commanding position in workplace productivity software as central to his investment thesis.
Diverging Views from Top-Tier Investors
Not all elite investors share Ackman’s optimism. TCI Fund Management, led by Chris Hohn and recognized as one of last year’s highest-performing hedge funds globally, discreetly offloaded the majority of its $8 billion Microsoft position — a stake maintained for ten years.
TCI communicated its rationale transparently to investors: “We reduced our investment in Microsoft because the rapid progress in AI introduces uncertainty over Microsoft’s competitive position in the future.”
This scenario presents two highly respected investment firms analyzing the same corporation and arriving at diametrically opposed decisions. The financial community is observing intently to determine which assessment proves accurate.
Microsoft CEO Satya Nadella appeared in an Oakland courtroom this week, providing testimony in Elon Musk’s litigation against OpenAI. The tech giant has committed approximately $12 billion to OpenAI across seven years and currently maintains a 27% ownership stake valued at around $230 billion. Musk’s legal action aims to dissolve this partnership, presenting genuine implications for Microsoft’s artificial intelligence roadmap.
AI Product Uptake and Capital Expenditure Concerns
On the operational front, Microsoft delivered adjusted earnings of $4.27 per share on $82.9 billion in revenue for its fiscal third quarter — exceeding analyst projections of $4.05 per share on $81.4 billion. Azure cloud platform expansion reached 40%.
The company’s capital expenditures have surged from $24 billion in fiscal 2021 to $88 billion in fiscal 2025, with projections of $190 billion for the current calendar year. This escalating investment is facing heightened examination as questions emerge regarding whether AI technologies are translating into tangible customer benefits.
Currently, Microsoft has secured 20 million paid subscriptions for its premium Copilot AI product, representing a fraction of approximately 450 million total enterprise seats. Tigress Financial Partners maintains a Buy recommendation with a $680 price objective — significantly above current trading levels — pointing to triple-digit annual growth in paid Copilot subscriptions.
Nonetheless, the Wall Street Journal disclosed that certain clients have experienced confusion regarding Microsoft’s diverse AI product nomenclature, with some opting for Google’s Gemini alternative instead. The company recently reorganized its AI division leadership.
Judson Althoff, who assumed responsibility for the commercial business in October, dismissed the concerns: “They don’t concern me, because I think the market is still trying to figure out AI.”
A research document released by Microsoft Research this week introduced a complicating factor to the AI narrative, determining that large language models “introduce sparse but severe errors that silently corrupt documents, compounding over long interaction.”
