Alphabet has become one of Berkshire Hathaway's largest holdings under Greg Abel's management, surpassing the value of its iconic Coca-Cola stake. Warren Buffett revealed he personally initiated the $31 billion investment in Google, noting that tech giants are compelled to compete in the AI race. Buffett's remarks helped push Google co-founder Larry Page's net worth above $300 billion, while Abel is backing Alphabet's AI infrastructure expansion with a $10 billion private placement.
