Berkshire Hathaway has built a stake in Alphabet worth roughly $36.6 to $37.8 billion, making Google's parent company its third-largest equity holding. The position, now about 10% of Berkshire's portfolio, combines open-market purchases with a $10 billion private placement tied to Alphabet's $80 billion AI infrastructure raise.
Warren Buffett spent decades steering Berkshire Hathaway away from technology stocks. Now the firm holds roughly 106 million shares of Alphabet Inc., Google's parent company. The position is valued at approximately $36.6 to $37.8 billion as of June 30, 2026.
That stake amounts to about 10% of Berkshire's equity portfolio, placing Alphabet behind only Apple and American Express among the firm's holdings. Alphabet stock rose approximately 70% year-over-year through late 2025, lifted by momentum in its Gemini AI models, accelerating Google Cloud revenue, and a buildout of computing infrastructure.
How Berkshire built the position
Berkshire started buying Alphabet shares on the open market in the third quarter of 2025, with those initial purchases valued at roughly $4 to $5.7 billion. It then made a far larger commitment in June 2026, joining a $10 billion private placement as part of Alphabet's broader $80 billion equity raise earmarked for AI infrastructure expansion.
Buffett initiated the investment before stepping back from daily operations at the end of 2025. His successor, Greg Abel, has continued the strategy.
A large bet against a backdrop of caution
For context, Berkshire's equity portfolio was valued between $299 billion and $362 billion in 2026 filings. The firm's cash balances peaked at $358 billion in September 2025, and deploying more than $36 billion into a single name is not a cautious allocation.
Alphabet's $80 billion equity raise, of which Berkshire's placement was a part, is one of the largest capital raises in recent technology history. Microsoft has deeply integrated OpenAI's models across its enterprise products, and Amazon Web Services continues to generate the largest cloud revenue base of any single provider. Meta is spending aggressively on its own AI infrastructure while keeping it proprietary. Alphabet is competing on all of these fronts simultaneously, using Search ad revenue as the funding engine.
The regulatory risk in the position
This stake carries a risk that Berkshire's traditional investments rarely carried: regulatory exposure. Alphabet is currently subject to antitrust proceedings in the United States tied to its dominance in search advertising. A structural remedy that forces changes to the Search distribution model could materially affect the revenue stream that funds everything else the company is building.
