Berkshire Hathaway disclosed in an August 14 regulatory filing that it added roughly $17 billion to its Alphabet holdings during the second quarter, an 83% increase that pushes the position to about 106 million shares worth $36.6-$37.9 billion. Alphabet is now Berkshire's third-largest equity holding, trailing only Apple and American Express.
About $10 billion of the new stake came through a private placement tied to Alphabet's capital-raising push for AI computing infrastructure, with the remaining $7 billion bought on the open market. CEO Greg Abel, who succeeded Warren Buffett at the start of the year, had agreed in June to expand the position Berkshire began building last fall; at the end of December 2025 the company held just 17.8 million Alphabet shares worth $5.6 billion.
The same filing showed Berkshire increasing its Delta Air Lines stake by 44% and boosting homebuilder Lennar by nearly 30%, while cutting Capital One by 58% and exiting its Constellation Brands position entirely. Berkshire's total equity portfolio now stands at roughly $299 billion.
