Berkshire Hathaway buys into Google parent Alphabet in landmark 13F filing
Warren Buffett spent years calling Google one of his biggest misses. Now Berkshire Hathaway has finally done something about it, disclosing a new stake in Alphabet valued at approximately $4.34 billion in its latest 13F filing.
The move marks the first time Berkshire has taken a position in Google’s parent company, a notable shift for a firm whose chairman long treated most tech stocks like a buffet item he’d rather skip.
What Berkshire actually bought
Here’s the thing. The $10 billion figure floating around social media does not match the actual regulatory filing. Berkshire’s disclosed Alphabet stake comes in at roughly $4.34 billion, which is substantial but less than half the number that got amplified online.
Buffett and his late partner Charlie Munger had previously admitted feeling “ashamed” for not investing in Google sooner. Munger used that exact word in public remarks, acknowledging that the company’s dominance in search advertising was plainly visible for years before Berkshire acted on it.
Why Alphabet, why now
Berkshire’s investment thesis has always centered on durable, cash-generating businesses with competitive moats. Alphabet checks those boxes more convincingly now than it did five or ten years ago.
Google’s cloud business has been expanding steadily, turning what was once a money-losing division into a legitimate profit center. The company’s investments in artificial intelligence have also caught Wall Street’s attention, positioning it as a credible competitor in the AI infrastructure race alongside Microsoft and Amazon.
Alphabet’s recent quarterly results have been strong. Revenue growth, margin expansion, and disciplined capital allocation have all improved the company’s fundamental picture.
It’s worth noting that Berkshire already held significant positions in Apple, which became its largest single holding over the past several years. The Alphabet purchase extends that comfort level with big tech into a second name, diversifying Berkshire’s technology exposure beyond a single company.
The broader 13F landscape
Berkshire’s Alphabet buy led a wave of 13F filings that institutional investors are required to submit quarterly, disclosing their US equity holdings.
The filing also reflects Berkshire’s ongoing preference for large, profitable companies. No cryptocurrency or digital asset positions appeared in the disclosure, which is consistent with Buffett’s well-documented skepticism toward the asset class.
What this means for investors
At $4.34 billion, this is a meaningful but not conviction-level bet relative to Berkshire’s total portfolio, which stretches into the hundreds of billions.
The competitive landscape for Alphabet remains intense. Microsoft’s partnership with OpenAI has reshaped expectations around search and AI-driven productivity tools. Amazon Web Services still leads the cloud infrastructure market by revenue. Regulatory scrutiny over Google’s search dominance continues in both the US and Europe, with antitrust proceedings that could force structural changes to the business.
