Berkshire Hathaway revealed a US $4.3 billion investment in Alphabet Inc. during Q3 2025, buying approximately 17.8 million shares. This strategic move occurred as Alphabet achieved its first US $100 billion revenue quarter. Berkshire’s purchase reflects a value-focused approach amid a tech market rotation, emphasizing Alphabet’s solid fundamentals and growth potential.
Berkshire Hathaway has disclosed a new US $4.3 billion position in Alphabet Inc. (GOOGL), confirming that Warren Buffett’s conglomerate entered the stock during the third quarter of 2025 — the same period in which Alphabet reported its first-ever US $100 billion revenue quarter.
According to Berkshire’s latest 13-F filing, the company purchased roughly 17.8 million shares of Alphabet, making it one of Berkshire’s ten largest equity holdings. The move surprised market watchers who have long associated Berkshire’s tech exposure primarily with Apple, which the firm trimmed in the same quarter.
A Contrarian Entry at a Trillion-Dollar Scale
Berkshire’s timing stands out. Alphabet shares were trading around US $270 – 280 during Q3 2025 — only modestly above their estimated intrinsic value range. While other institutional investors were rotating out of mega-cap tech after two years of outperformance, Berkshire appears to have treated Alphabet as a value compounder rather than a momentum play.
For Buffett followers, the purchase echoes a familiar pattern: buying into a cash-rich franchise once its growth narrative collides with valuation discipline. Alphabet fits that mold neatly — a business generating more than US $80 billion in free cash flow annually, returning US $15 billion in quarterly buybacks, and maintaining over US $100 billion in cash reserves.
Fundamentals Back the Move
Alphabet’s Q3 2025 report, released October 29, underscored that growth and prudence can coexist in Big Tech.
Revenue: US $102.3 billion (+16 % YoY)
Operating Income: US $31.7 billion (+23 %)
EPS: US $2.87
Google Cloud: +34 % YoY, margin rising to 9 %
CapEx: Raised to US $91 – 93 billion for AI data-center expansion
CEO Sundar Pichai described the period as “a reflection of how AI is transforming every corner of our business,” while CFO Ruth Porat stressed “disciplined long-term investment.”
Those remarks align closely with Buffett’s own playbook — durable cash flow, reinvestment discipline, and capital allocation guided by intrinsic value rather than quarterly optics.
Reinforcing the “Still Underpriced” Thesis
Our prior SWOTstock analysis of Alphabet’s Q3 results placed fair value near US $284 per share, with the market trading just above that level post-earnings. Berkshire’s purchase suggests that even at these prices, long-term investors still see a margin of safety — particularly as Alphabet’s AI infrastructure spending begins to translate into productivity and monetization gains across Search, YouTube, and Cloud.
For value-oriented readers, the implication is clear: when Berkshire buys into a trillion-dollar tech name after a record quarter, it’s not chasing growth — it’s buying durability.
Market Reaction
The disclosure briefly lifted Alphabet shares in after-hours trading on Friday, as investors digested the significance of Berkshire’s first new mega-cap tech stake in years. Analysts now expect fresh comparisons between Alphabet’s AI capital discipline and Apple’s maturing growth profile, which Berkshire has been gradually reducing.
As of mid-November 2025, Alphabet trades around US $277, giving the stake a paper value near its initial cost — a rare instance where Buffett’s patience and Alphabet’s execution appear perfectly aligned.

Alphabet Posts Strong Q1, But Market May Be Pricing in Perfection
Alphabet (GOOGL) reported a strong start to 2025 with double-digit revenue growth, rising margins, and expanding AI product integration. While profits hit record highs, ballooning CapEx and regulatory risks could limit near-term upside. Our fair value estimate suggests the stock may be slightly ahead of fundamentals.
Alphabet Q1 2025 Financial Results: What Investors Need to Know
Alphabet’s Q1 2025 earnings report showed continued strength across its diversified business. Total revenue reached $80.5 billion, a 15% year-over-year increase, and net income surged 57% to $23.7 billion. Diluted earnings per share (EPS) climbed 61% to $1.89, signaling strong leverage and cost efficiency.
Operating income came in at $25.5 billion, with an operating margin of 32%, in line with Q1 2024. Alphabet’s free cash flow was $24 billion, while CapEx rose to $12 billion, driven by data center and AI infrastructure expansion.
What Management Said
CEO Sundar Pichai emphasized Alphabet’s strategic edge in AI, citing the Gemini 1.5 Pro rollout and AI Overviews’ growing presence across Search. He noted Alphabet’s unique “full-stack AI infrastructure,” pointing to TPUs, software, and user reach as key differentiators.
CFO Ruth Porat highlighted the decision to increase capital expenditures to support AI momentum. She also announced Alphabet’s first-ever $0.20 per share dividend and a $70 billion share buyback, marking a significant shift toward shareholder returns.
Alphabet SWOT Analysis: Strengths, Weaknesses, Opportunities, and Threats
Let’s break down Alphabet’s Q1 2025 performance using a SWOT framework to identify what’s working, what’s vulnerable, where the upside is, and what could derail the story.
Strengths
Alphabet’s core businesses are performing exceptionally well. The company delivered 15% year-over-year revenue growth and a 57% jump in net income, thanks to strong contributions from Google Search, YouTube, and Cloud. More importantly, AI is no longer just a buzzword—it’s integrated across Gmail, Docs, and Search via Gemini 1.5 Pro. With more than 2 billion users across its top products, Alphabet has the scale and data to monetize AI faster and more effectively than most competitors. These factors could justify a $15–$20 per share upside if sustained.
Weaknesses
Despite strong profits, Alphabet’s spending is surging. The company reported $12 billion in capital expenditures this quarter alone, much of it directed toward building the infrastructure for AI. While this investment may pay off in the future, it puts pressure on near-term free cash flow. Also, Alphabet still leans heavily on advertising, which made up about 77% of revenue this quarter. That level of dependency makes the business vulnerable to economic slowdowns or policy shifts. These factors could limit upside by $5–$10 per share.
Opportunities
Alphabet is in the early stages of monetizing its AI assets. Gemini is already powering Search, Workspace, and Cloud features, and it’s being rapidly rolled out across Alphabet’s enterprise stack. YouTube subscriptions also crossed 100 million globally, while YouTube TV has over 8 million paying users—offering growing streams of recurring revenue. Cloud continues to grow 28% year-over-year, creating opportunities to deepen AI platform revenue. If Alphabet executes well, these growth drivers could add $25–$40 per share to the company’s valuation.
Threats
Alphabet’s biggest risks lie in regulation and competition. Multiple antitrust lawsuits and regulatory probes remain ongoing in both the U.S. and EU, and any adverse rulings could force structural changes to key business models like Search or Ads. At the same time, AI competition is accelerating—especially from Microsoft and OpenAI, who are also investing heavily in enterprise solutions. Finally, the stock is trading near its all-time high, meaning much of the good news may already be priced in. If these risks materialize, they could take $20–$30 off the stock’s valuation.

Verdict: ✅ Hold — If you’re a long-term investor, Alphabet’s AI positioning and scale are unmatched. ❌ Not a Buy Yet — Wait for a better entry if you’re looking for margin of safety.
