Overview
- Berkshire's filings Wednesday show the company holds roughly 106 million Alphabet shares worth about $36–$38 billion, equal to roughly 10–10.5% of its public-equity portfolio.
- Purchases of Alphabet began in Q3 2025 under Warren Buffett, but most new buying happened after Greg Abel became CEO earlier this year, with Buffett reported to have encouraged the initial move.
- Apple and Alphabet now together represent about 31% of Berkshire's public stock holdings, a degree of concentration that recalls the company's past heavy exposure to Apple.
- Operationally Berkshire's wholly owned businesses have shown little change under Abel and there have been no major new acquisitions since he took the role.
- Analysts note the trade leans on Alphabet's rapid cloud and AI-driven growth but raises risks because Alphabet is running unusually large capital expenditure plans and faces regulatory scrutiny, which could amplify portfolio volatility or prompt future stake trimming.
