24% of Warren Buffett's $300 Billion Portfolio Is Invested in 3 Artificial Intelligence (AI) Stocks, Including This Recent Purchase

Despite Warren Buffett's expressed caution regarding artificial intelligence, Berkshire Hathaway's marketable equities portfolio holds significant indirect exposure to the technology through key holdings. Apple, representing 23.1% of the portfolio, is actively integrating generative AI features into iOS and making foundation models available, though Berkshire has reduced its stake partly due to valuation concerns. Amazon, a smaller 0.7% holding, is a major AI beneficiary via its AWS cloud services, which are experiencing triple-digit growth in AI offerings and driving substantial capital expenditures for data centers. Furthermore, Berkshire's recent addition of Nucor, a steel manufacturer, benefits from surging demand for data center construction fueled by AI, despite facing short-term margin pressure from increased electricity costs.

Analysis

Despite Warren Buffett's expressed caution regarding generative AI, Berkshire Hathaway's $300 billion marketable equities portfolio holds approximately 24% in three key stocks with significant AI exposure. This positioning indicates a strategic, albeit indirect, embrace of the AI trend, aligning with the article's overall moderately positive sentiment regarding these developments.

Apple (AAPL), Berkshire's largest holding at 23.1% ($69.4 billion), is actively integrating generative AI features into iOS and making foundation models available to developers. However, Berkshire reduced its stake by nearly 70% since late 2023, primarily due to valuation concerns at 31x forward earnings for a slower-growing company, rather than its AI initiatives, as reflected by AAPL's negative per-ticker sentiment.

Amazon (AMZN), a smaller 0.7% position, is a major AI beneficiary through its AWS cloud services, which are experiencing triple-digit growth in AI offerings and driving over $100 billion in capital expenditures for data centers. This robust performance is underscored by AMZN's highly positive per-ticker sentiment. Berkshire's recent acquisition of Nucor (NUE), representing 0.3% of the portfolio, further benefits from AI-driven demand, with steel shipments for data centers doubling and construction spending projected to accelerate to 26% in 2026, despite short-term margin compression from rising electricity costs.

Key Decisions for Investors

• Investors should assess their AI exposure, noting Berkshire's diversified approach through indirect beneficiaries like Apple, Amazon, and Nucor.
• Monitor Apple's AI feature development and valuation multiples, as Berkshire's stake reduction suggests sensitivity to growth-adjusted pricing.
• Consider Amazon's AWS as a direct play on AI infrastructure growth, given its triple-digit AI service growth and substantial capital expenditure plans.
• Evaluate Nucor's long-term potential as an AI infrastructure enabler, balancing short-term margin pressures against accelerating data center construction demand.
