Berkshire Is Chasing GOOG Stock Big Time, But It Might Not Help Reverse Warren Buffett’s Historical Mistake

Berkshire Hathaway added $17 billion worth of Alphabet shares to its portfolio in the second quarter of 2026, bringing its stake to $36.6 billion. This makes Alphabet the third biggest holding for the conglomerate, after Apple and American Express. The increase in Alphabet shares suggests Berkshire added another $7 billion through open market purchases.

Despite Berkshire's significant investment, Berkshire's CEO, Warren Buffett, admitted that he doesn't like Alphabet as much as some other holdings. Buffett compared the risks of AI to nuclear bombs and expressed concerns about the technology enabling scams. However, Berkshire sees Alphabet as a play in the AI space. The company's Q2 2026 revenue grew by 24% year-over-year, with cloud revenues increasing 82% YoY.

Despite the potential upsides, Buffett doesn't expect Alphabet to be as profitable an investment for Berkshire as Apple, which he considers his best investment ever.
