Berkshire Finally Buys Google

Why This Matters

Warren Buffett has called Google "one of the biggest missed opportunities" in Berkshire's history. Charlie Munger described it as "our worst mistake in the tech field." For over two decades, they watched Google compound from a search engine into a $2 trillion advertising, cloud, and AI infrastructure company — without buying a single share. In Q3 2025, that changed.

The Core Investment Thesis

Berkshire's $4.3 billion position in Alphabet represents either an admission of past error or recognition that Google has finally become cheap enough to meet value investing criteria. Given the timing — coinciding with Greg Abel's assumption of the CEO role in January 2026 — this may signal a philosophical shift in how Berkshire approaches technology investments.

Key Arguments

Argument #1: The Moat Finally Became Undeniable

Buffett avoided Google for years because he couldn't confidently predict its competitive position a decade out. Search dominance might erode; advertising could shift to new platforms; regulatory intervention might break up the company. Two decades later, none of these threats materialized.

Data: Google maintains 90% global search market share. YouTube generates over $50 billion in annual revenue. Google Cloud is a distant but growing third behind AWS and Azure. The company produces $73 billion in annual free cash flow.

The competitive position hasn't just maintained — it's strengthened. Network effects in search, data advantages in advertising, and infrastructure moats in cloud computing create interlocking barriers that grow over time rather than eroding.

Argument #2: AI Infrastructure Position Is Undervalued

Google's AI capabilities may be the most underappreciated aspect of the investment. While headlines focus on ChatGPT, Google's AI infrastructure advantages span hardware (TPUs), models (Gemini), and distribution (Android, Chrome, Search).

Data: Google's proprietary TPU chips are preferred by many AI companies over Nvidia GPUs for certain workloads. The company has been deploying AI in products for years — Search, Gmail, Photos, Maps — creating implementation experience competitors lack.

The market prices Google as an advertising company threatened by AI. The reality is Google may be the best-positioned company to monetize AI at scale through its existing distribution and infrastructure advantages.

Argument #3: Valuation Finally Reflects Margin of Safety

At 27x forward earnings, Google trades cheaper than its own historical average and significantly below high-growth tech peers. Add $73 billion in annual free cash flow and the company's first-ever dividend, and the risk/reward has shifted.

Data: Berkshire's 17.85 million share position represents approximately $4.3 billion — the 10th largest position in a $266 billion equity portfolio. This isn't a token bet; it's a meaningful allocation.

The purchase timing — Q3 2025, shortly before Greg Abel assumes CEO responsibilities — suggests this may reflect the next generation's investment philosophy rather than Buffett's historical approach. Todd Combs and Ted Weschler have long advocated for technology exposure.

Risks & Counterarguments

• Antitrust Intervention: Google faces ongoing antitrust litigation that could result in business breakup, behavioral remedies, or significant fines. The DOJ has explicitly sought structural remedies.
• AI Disruption to Search: ChatGPT and competitors demonstrate that conversational AI can answer questions without traditional search. If users shift to AI chatbots, Google's core advertising business faces disruption.
• Buffett Timing Record on Tech: Buffett's IBM investment lost money; his Apple investment succeeded spectacularly. The Google purchase could go either way, and Buffett has acknowledged technology is outside his traditional circle of competence.

Bottom Line

Berkshire's Google investment closes a two-decade chapter of regret. Whether this represents Buffett correcting an error or the next generation reshaping Berkshire's portfolio philosophy, the logic is sound: Google offers monopoly-like economics in search advertising, growing AI infrastructure advantages, and $73 billion in free cash flow at a valuation reflecting none of this optionality. The 27x multiple may look expensive to deep value investors, but for a company of Google's quality and growth, it represents reasonable value.

Verdict: The Buffett regret trade, 20 years in the making
