Big Buy into Google: What Signals Does Buffett's Portfolio Report Before "Retirement" Reveal?

Warren Buffett's Berkshire Hathaway recently released its Q3 13F report, which may well be Buffett's last holdings disclosure before his "retirement" at year-end.

 

A highly watched move: The report shows Berkshire shifted bets on U.S. tech giants—major new stake in Alphabet (Google parent), promoting it to 10th largest holding.  

 

Specifically, in Q3, Berkshire bought ~17.85 million shares of Alphabet, corresponding to ~$4.3 billion market value at quarter-end, its first position in Google parent. Alphabet was Berkshire's biggest Q3 buy and its only new holding that quarter.  

 

Berkshire's investment in Alphabet surprised markets, as Buffett has long stuck to value investing and been cautious on high-growth U.S. tech stocks. Though top holding Apple, Buffett has said iPhone-maker Apple more like consumer goods company. Thus, I believe Berkshire's major stake in Alphabet reflects Buffett team's rethinking of tech stocks, a clear embodiment of tech investment value.  

 

 

On one hand, Berkshire's stake in "pure" tech stock Alphabet, though unexpected, makes sense, consistent with its value investing logic. As world's fourth-largest tech giant by market cap, Alphabet has diversified revenue from core segments like ads, cloud, search, with deep "moat."

 

Company earnings show Q3 2025 revenue $102.346 billion, up 16% YoY, above expected $99.9 billion. Among them, AI boom-driven cloud business growth accelerated to 34% YoY.  

 

On the other hand, Alphabet not only has broad tech "moat," but leads in growth. Public data shows end-Q3, Google AI app Gemini monthly active users over 650 million, AI tech monetization showing strong momentum, Google says AI bringing real business results to entire company.  

 

Clearly, Alphabet's blend of "defense" and "growth" fits Buffett value investing philosophy—finding excellent enterprises with wide "moats" and sustained cash flow creation.  

 

For global investors, Buffett's pre-"retirement" holdings report provides clear weather vane—in era of artificial intelligence as new core productivity, actively embracing tech transformation, mature business models, cash-rich tech giants becoming key value investment targets.

 

Value investing, long-termism not clinging to traditional industries, but in ongoing tech revolution, seeking enduring value core.
