Berkshire Hathaway made a large purchase of Alphabet shares during the second quarter of 2026, marking its biggest portfolio move for the period.
The investment signals a strategic shift by Warren Buffett's firm to capitalize on the rapid growth of artificial-intelligence related businesses. By increasing its stake in the AI hyperscaler, Berkshire is positioning itself within a sector that has seen significant volatility and growth.
Berkshire Hathaway now has approximately 10% [1] of its total portfolio invested in Alphabet. The total value of the firm's portfolio stands at $358 billion [1]. This move comes as the tech giant's stock has increased by 70% [1] over the past year.
The purchase occurred throughout the second quarter of 2026. While Berkshire has historically maintained a cautious approach toward high-growth tech stocks, the scale of this acquisition suggests a higher confidence in the long-term viability of AI infrastructure.
The move reflects a broader trend of institutional investors shifting capital toward companies capable of scaling AI operations. Alphabet's role as a hyperscaler, a provider of massive cloud computing and AI capabilities, makes it a central pillar of this technological transition.
Berkshire Hathaway continues to manage its diverse holdings across various U.S. industries, but the concentration in Alphabet represents a significant bet on the future of search and generative AI.
“Berkshire Hathaway now has approximately 10% of its total portfolio invested in Alphabet.”
This move indicates that Berkshire Hathaway is moving past its traditional hesitation regarding the tech sector's valuation. By allocating a tenth of its massive portfolio to a single AI-driven entity, the firm is acknowledging that AI is no longer a speculative venture but a core driver of global economic value.
