Bill Ackman Reveals New Microsoft Stake — Compares MSFT Setup To Earlier GOOG, AMZN, META Bets

• Ackman said the convergence of rising passive index ownership and the growing influence of short-term, leveraged, volatility-sensitive investors has occasionally created rare dislocations in high-quality stocks.
• He said Microsoft’s two core franchises, M365 and Azure, generate roughly 70% of the company’s profits.
• Ackman described M365 as the dominant workplace productivity platform, used daily by more than 450 million people across Word, Excel, Teams and Outlook.

Billionaire hedge fund manager Bill Ackman on Friday revealed that Pershing Square has acquired a new stake in Microsoft Corp. (MSFT), adding that the firm will disclose the position in a 13F filing later today.

Ackman also stated in a post on X that his closed-end fund, Pershing Square USA (PSUS), also made Microsoft a core holding recently.

“In our view, investors underestimate the resilience of the M365 franchise given its deeply embedded role across enterprises and highly attractive price-value proposition,” Ackman said.

Microsoft shares were up about 0.3% in Friday’s pre-market trade. MSFT was among the top trending tickers on Stocktwits at the time of writing.

Ackman Sees Rare Mega-Cap Buying Opportunities Amid Market Volatility

Ackman said the convergence of rising passive index ownership and the growing influence of short-term, leveraged, volatility-sensitive investors has occasionally created rare dislocations in high-quality stocks.

“Like our purchases of $GOOG, $AMZN, and $META, we believe that $MSFT offers analogous and compelling long-term value at today's valuation,” Ackman added.

He pointed to earlier purchases of Alphabet Inc. (GOOG, GOOGL) following the ChatGPT-driven selloff in late 2022, Amazon.com Inc. (AMZN) after the post–Liberation Day decline, and Meta Platforms Inc. (META) more recently after investor concerns surrounding the company’s elevated capex guidance.

Ackman Lays Down His Bull Thesis For MSFT

Ackman said the fund began building its Microsoft position in February following the stock’s selloff after the company’s fiscal Q2 2026 results. He added that Pershing established the stake at roughly 21x forward earnings, near the broader market multiple and below Microsoft’s historical average valuation.

Ackman added that Azure, the world’s second-largest hyperscaler, is benefiting from the long-term cloud shift and rising AI demand. He also highlighted Microsoft’s broader ecosystem, including LinkedIn, Xbox, Activision Blizzard, Bing and Edge.

Ackman said unlike standalone software tools that could be displaced by stronger AI competitors, M365 remains deeply embedded in the day-to-day operations of large enterprises.

He added that Microsoft’s extensive identity, security, compliance and data governance infrastructure creates a competitive moat that would be extremely difficult to replicate.

When Did Ackman Start Acquiring MSFT Stock?

Ackman said the fund began building its Microsoft position in February this year after the stock sold off following the company’s second-quarter (Q2) results.

He added that the stake was established at roughly 21x forward earnings, which is close to the broader market multiple and well below Microsoft’s historical trading average.

MSFT stock has declined 15% year-to-date, while GOOGL stock is up 28%. AMZN stock has gained 16% during this period, while META stock is down 6%.
