Berkshire Hathaway Quietly Built a $37.4 Billion Stake in Alphabet, Making It the Portfolio's Third-Largest Position

Berkshire Hathaway has built a $37.4 billion position in Alphabet, now the conglomerate's third-largest holding. The stake was accumulated gradually from Q3 2025 through Q2 2026, a sustained buying window rather than a single block purchase.

Warren Buffett personally initiated the investment, according to the report. That detail carries weight: Buffett has historically avoided technology stocks, so a $37.4 billion commitment marks a notable departure from his long-standing pattern. The stated rationale is that Alphabet can earn high returns on capital over an extended period, a framing consistent with the quality-compounder logic Buffett has long applied elsewhere.

Alphabet trades under several tickers, including GOOG, GOOGL, GOOGM, and GOOGN. Berkshire's own shares trade as BRK.A and BRK.B.

Interpretation: a third-place ranking in the portfolio signals high conviction, since only two positions are larger. The multi-quarter accumulation also suggests Berkshire was willing to build size patiently rather than chase price. That pattern can matter for sentiment, though the supplied evidence does not show how GOOG or GOOGL have traded in response.
