Berkshire Hathaway Shifts to AI: Apple and Alphabet Dominate Portfolio

Under CEO Greg Abel, Berkshire Hathaway has fundamentally reshaped its investment strategy, committing nearly 30% of its $348 billion portfolio to Apple and Alphabet. This move marks a definitive departure from the traditional value-investing approach associated with Warren Buffett, reflecting a direct embrace of the technology sector. The company's heavy concentration in these two firms signals an intentional bet on the long-term potential of artificial intelligence infrastructure and device ecosystems.

The shift is driven by Alphabet's inclusion as a core holding, with Berkshire tripling its stake since late 2025. Berkshire recently acted as an anchor investor in an $80 billion AI infrastructure capital raise, purchasing $10 billion of Alphabet shares via private placement in June. This reflects a shift toward direct engagement with the growth phases of technology giants, rather than waiting for classic value-based entry points.

While the tech tilt positions Berkshire to benefit from the ongoing AI transition, it exposes the conglomerate to new volatility risks. A market correction in either Apple or Alphabet would disproportionately affect Berkshire's overall valuation, given the portfolio's concentrated nature. Investors are closely watching how this aggressive growth strategy performs compared to the firm's historical focus on diversified holdings like consumer staples and banking, as the firm transitions into this new era of tech-led growth.
