Berkshire Hathaway adds $17 billion to its Alphabet stake

Warren Buffett's Berkshire Hathaway increased its stake in Google parent Alphabet by $17 billion during the second quarter, according to a regulatory filing released this week. The move cements Alphabet as the third-largest position in Berkshire's equity portfolio, behind only Apple and American Express.

Berkshire's stock holdings have long centered on a handful of established giants, and Alphabet's rise reflects growing conviction in the tech company's artificial intelligence and cloud computing businesses. Analysts said the increase may signal a shift in strategy from the team now overseeing Berkshire's equity investments as Buffett steps back from day-to-day decisions.

The disclosure comes as Alphabet shares have posted strong gains this year, buoyed by enthusiasm over its AI products. Investors will watch closely for whether Berkshire continues to expand the position in coming quarters.
