Berkshire Hathaway's latest 13F filing, released in mid-November 2025, revealed a significant new investment in Google's parent company, Alphabet. The conglomerate acquired a stake valued between $4.3 billion and $4.9 billion, making Alphabet one of Berkshire's top ten largest holdings. This move marks a notable pivot for the firm, which has traditionally been cautious with technology investments. This new position in Alphabet was disclosed alongside a continued reduction of Berkshire's largest holding, Apple. The filing indicated a 15% decrease in its Apple shares. Following the announcement of Berkshire's investment, Alphabet's shares experienced a significant surge, climbing nearly 6% to reach a new all-time high.
