Alphabet shares surged nearly 6% to a record high Monday after Berkshire Hathaway disclosed a $4.93 billion stake, signaling confidence in the tech giant’s AI ventures. The purchase of 17.85 million shares marks a rare move into tech for Buffett’s traditionally conservative conglomerate.
Steve Sosnick, chief strategist at Interactive Brokers, said, “The stake purchase of a tech company may represent a different type of mentality at Berkshire, though it’s not a total departure from its value-investing model.”
The investment comes amid broader tech caution, as AI-driven stock surges spark concerns over overvaluation. Despite this, Alphabet has outperformed peers in the “Magnificent Seven” group, rising nearly 14% this quarter and 46% year-to-date, while trading at lower forward earnings multiples than Microsoft and Nvidia.
Analysts highlight Alphabet’s leadership in AI, noting its strong infrastructure, AI search adoption, and a robust ad business funding its expansion. CFRA analyst Angel Zino said, “The move validates Google’s strong fundamentals and provides Berkshire exposure to a leading AI provider through Google Cloud and Gemini expansion.”
The purchase also allows Buffett and Berkshire managers to address past regrets over missing early Google investments, as the conglomerate prepares for a CEO transition at the end of 2025. Shares climbed further with retail investor interest, positioning Alphabet among the top trending stocks on Stocktwits.
Despite this selective tech bet, Berkshire remains a net seller overall, trimming positions in Apple and Bank of America, and holding a record $381.7 billion in cash.
