Cambio estratégico de Warren Buffett: desde Apple y Bank of America hasta Alphabet impulsado por IA

Warren Buffett's Berkshire Hathaway has long been a paragon of value investing, favoring stable, cash-generative businesses with durable competitive advantages. However, the third quarter of 2025 marked a pivotal pivot in the conglomerate's strategy. By selling nearly 74% of its Apple shares over two years and reducing its Bank of America stake to 9.6% of its portfolio, Berkshire has signaled a recalibration toward artificial intelligence (AI). The $4.3 billion investment in Alphabet-Google's parent company-represents not just a tactical move but a strategic acknowledgment of AI's transformative potential in reshaping global markets. This shift reflects a broader reallocation of value from legacy assets to AI-driven enterprises, driven by evolving market dynamics and technological innovation.

The Decline of Legacy Holdings: Apple and Bank of America

Berkshire's divestment from Apple and Bank of America underscores a growing skepticism toward traditional value propositions. Apple, once a cornerstone of Buffett's portfolio, has faced stagnation, with flat revenue growth and a lack of disruptive innovation in recent years. Similarly, Bank of America, while a stalwart in financial services, has flagged the risks of AI-driven capital expenditures, noting that top tech firms now allocate 94% of their free cash flow to AI infrastructure, often financed through debt. These trends suggest that even well-established institutions are struggling to keep pace with the rapid capital demands of AI, prompting Berkshire to reassess its long-term bets.

Alphabet's AI-Driven Ascendancy

Alphabet's emergence as a dominant force in AI has positioned it as an attractive alternative. The company's investments in cloud computing, custom AI chips (Tensor Processing Units), and advanced models like Gemini have created a vertically integrated infrastructure that rivals competitors like Microsoft and Amazon. According to data, Alphabet's financial strength further solidifies its appeal: it reported a historic $100 billion quarterly revenue and raised $25 billion in bonds to fund AI and cloud expansion, with 2025 capital expenditures projected at $91–93 billion. For Buffett, Alphabet's combination of a robust advertising business model and AI-driven innovation aligns with his preference for companies with strong brands and consistent cash flows. According to reports, this alignment has been a key factor in the investment decision.

Value Reallocation in the AI Era

The broader market is witnessing a seismic shift in value allocation, with AI capturing a growing share of corporate and institutional investments. According to the 2025 McKinsey Global Survey, nearly all organizations now use AI in at least one business function, while Deloitte's 2025 Tech Value Survey notes that 74% of firms prioritized AI and generative AI over other technologies. Corporate AI investment reached $252.3 billion in 2024, with private investment surging by 44.5% and AI-related M&A rising by 12.1%. In banking, AI adoption has accelerated, with institutions investing $35 billion in 2023 to enhance operational efficiency, risk management, and customer experience. Alphabet's dominance in this landscape positions it as a natural beneficiary of these trends.

Buffett's Evolving Philosophy: Caution Meets Adaptation

Buffett's investment philosophy has historically emphasized patience and simplicity, avoiding volatile sectors like technology. However, his regret over not investing in Google earlier-expressed during the 2017 Berkshire annual meeting-has long hinted at a latent recognition of AI's potential. The Alphabet stake now reflects a calculated barbell strategy: investing in both AI leaders and foundational infrastructure. For instance, Berkshire Hathaway Energy's investments in U.S. energy grids to support AI data centers illustrate a commitment to enabling the AI ecosystem without overexposure to speculative ventures. This approach balances Buffett's risk-averse ethos with the need to adapt to technological disruption.

Strategic Implications and Market Reactions

Berkshire's shift has sparked debate about its evolving investment criteria. While Buffett remains skeptical of overvalued AI stocks, his willingness to embrace Alphabet suggests a nuanced view of the sector's long-term value. Analysts note that this move aligns with Alphabet's strategic positioning in AI, particularly its Gemini model and Chrome ecosystem, which are poised to drive user engagement and ad effectiveness. Meanwhile, the reduction in Apple and Bank of America shares signals a rebalancing of Berkshire's portfolio toward high-growth, AI-centric assets-a departure from its traditional focus on stable, low-volatility holdings.

Conclusion

Warren Buffett's strategic pivot to Alphabet underscores a critical juncture in the evolution of value investing. As AI redefines industries, Berkshire's ability to adapt its portfolio to emerging opportunities will determine its relevance in a rapidly changing market. By leveraging Alphabet's AI-driven growth while mitigating risks through infrastructure investments, Buffett is navigating the delicate balance between caution and innovation. This shift not only reflects Alphabet's ascendancy but also highlights the broader reallocation of capital toward technologies that promise to reshape the global economy.
