Overview
- Three Sept. 16 reports say Berkshire began buying Alphabet in Q3 2025 but accelerated the purchases after Greg Abel became CEO at the start of 2026.
- Berkshire has bought nearly 106 million shares of Alphabet, making it a top-five holding that now represents about 10 to 10.5% of the company’s public-equity portfolio.
- Apple remains the largest single position at roughly 20.8%, leaving Apple and Alphabet to account for about 31% of Berkshire’s public stock holdings.
- The Alphabet build included participation in a mid-2026 private placement and an 83% quarter-over-quarter increase in the stake reported in the latest quarter.
- Operationally Berkshire’s wholly owned businesses show little change and no major acquisitions have been announced under Abel, but the heavier tech weighting increases exposure to AI-driven growth, Alphabet’s large capital spending, and related valuation and regulatory risks.
