Under Greg Abel, Apple and Alphabet Now Make Up Nearly 30% of Berkshire Hathaway's $348 Billion Stock Portfolio. Here's Why.

Under new CEO Greg Abel, Berkshire Hathaway has significantly concentrated its $348 billion stock portfolio in Apple (20.6%) and Alphabet (8.8%), reflecting a strategic shift toward AI-driven tech companies. Abel tripled Berkshire's Alphabet position, including a $10 billion private placement to fund the company's $80 billion AI infrastructure expansion. While this concentration signals confidence in these companies' AI prospects and their durable competitive moats, it also increases portfolio risk if either company stumbles or AI investments fail to deliver expected returns.
