- Berkshire Hathaway’s stake served as an endorsement of Google’s AI efforts
Berkshire Hathaway’s stake in Alphabet caused the tech giant’s stock to surge more than 5% on November 17, 2025. According to Yahoo Finance, Berkshire Hathaway reported owning 17.85 million Alphabet shares worth approximately $4.93 billion based on recent closing prices.
Why Alphabet’s Shares Rallied in Pre-Market Trading
Berkshire’s stake in Alphabet, which is a rare bet by the Warren Buffett conglomerate, served as an endorsement of the tech company’s AI efforts. Buffett has been reluctant to invest in tech investments and has said that he cannot predict it.
Today’s Alphabet stock rally comes at a time when investors are exercising more caution in tech investments. Several experts have warned that the AI boom, which has been driving tech stock prices, has detached valuations. Business leaders have also warned that returns from data center spending are still uncertain.
Despite these concerns, capital spending of tech giants like Microsoft continues to exceed investor expectations. The tech giant plans to increase capital spending this year to meet growing demand for cloud computing.
Alphabet is also seeking to expand its AI and cloud infrastructure. Earlier this month, the company announced plans to re-enter Europe’s bond market in a bid to raise €6.25 billion.
Alphabet’s Impressive Stock Performance
Alphabet stock has gained 14% in the December 2025 quarter. This year, the stock has gained 46%, making it the best-performing among the Magnificent Seven.
Analysts have said that Alphabet’s early adoption of AI search tools, huge ad business, and growing investment in AI infrastructure position it as a leader in the technology. In recent months, the tech giant has made significant progress in monetizing its AI investment after it integrated Gemini AI into multiple products.
Key among these products is Gemini Enterprise, an AI-powered platform designed to bring Google AI to every workflow. Gemini Enterprise Standard and Plus editions target large companies at a cost of $30 per person per month. The Gemini Business plan, which targets smaller businesses or individuals, is priced at $21 per person per month.
Last month, investors rushed to buy Alphabet stock after earnings showed that Google Cloud was becoming an important growth driver for the company.
Berkshire Hathaway’s Effect on Alphabet Stock
Stocks tend to surge when Berkshire reveals new positions due to Buffett’s perceived approval. Berkshire’s disclosure attracted interest from retail investors, a move that placed Alphabet stock among the three trending stocks.
Going by Monday’s early trading, Alphabet stock is expected to add approximately $160 billion to the company’s market capitalization if gains hold.
Berkshire offloaded stocks in Apple and Bank of America in the September quarter. The company’s equity portfolio continues to lean heavily towards financial services, which represented 36.6% of its investment as of September 2025.
