Berkshire Hathaway Has 10% of Its $358 Billion Portfolio Invested in 1 AI Hyperscaler Whose Stock Is Up 70% in 1 Year

Berkshire Hathaway has significantly increased its investment in Alphabet, making it the conglomerate's third-largest holding worth $36.6 billion. Warren Buffett initiated this position last year, betting on Alphabet's AI infrastructure expansion despite massive capital expenditures causing negative free cash flow. Despite a 70% stock price surge over 12 months, Alphabet trades at a P/E ratio 34% below the S&P 500, suggesting attractive valuation.
