Overview
- Berkshire Hathaway’s latest 13F shows about 17.8 million Alphabet Class A shares as of Sept. 30, a position reported at roughly $4.3 billion to $4.9 billion at recent prices.
- The purchase marks a rare move for Berkshire into a high‑growth tech name and is widely viewed as an endorsement of Alphabet’s business durability and AI trajectory.
- Alphabet has been one of 2025’s standout stocks, rising nearly 60% this year and ranking as the second‑largest point contributor to the S&P 500’s gains.
- Optimism has been reinforced by AI product advances, including a new Gemini model with improved reasoning and coding, alongside strong Google Cloud growth and a quarter near $100 billion in revenue.
- The rally has lifted Alphabet’s valuation to about 25 times forward earnings, above its 10‑year average near 20, and Berkshire has not disclosed who authorized the trade.
