Berkshire Hathaway's GOOGL position: 28.2 billion dollars

Berkshire Hathaway added 45% to its Alphabet Class A (GOOGL) stake in the second quarter of 2026, bringing the position to $28.2 billion. This makes GOOGL the fourth largest holding in Warren Buffett's portfolio, behind only Apple, American Express, and Coca-Cola. The filing shows a deliberate build into this single position across the quarter.

!Berkshire's 10 largest holdings. GOOGL is now 9.4% of the $299.3 billion portfolio, fourth after Apple 22%, AmEx 17.1%, and Coca-Cola 10.9%

What does Alphabet actually do?

Alphabet is the holding company for Google and a range of other technology ventures. The core business is search advertising, where Google captures roughly 90% of the global search market. When you type a query into Google, the ads that appear above and beside the organic results generate the vast majority of Alphabet's revenue. YouTube, owned by Alphabet since 2006, is the second major revenue driver, monetized through video ads and subscriptions. The company also operates cloud infrastructure services, enterprise software, hardware (Pixel phones, Nest devices), and an autonomous vehicles division through Waymo. A smaller bet sits in "Other Bets," experimental ventures in areas like life sciences and renewable energy that operate at a loss.

Alphabet's economic moat rests on network effects in search (the more queries it processes, the smarter its algorithms become) and on scale in advertising technology. It competes with Microsoft (which has integrated OpenAI), TikTok (for user attention), and Amazon (for advertising dollars), but none of those competitors have displaced Google's dominance in search.

How large is this stake relative to the rest of the book?

At $28.2 billion, GOOGL alone represents nearly 9.4% of Berkshire's entire $299.3 billion reported equity portfolio. The top 10 holdings make up 88.5% of the book, and GOOGL is solidly inside that core group. To put the scale in perspective, the position is only $1.3 billion smaller than Berkshire's entire stake in Bank of America, which sits at 9.2% of the portfolio.

The increase was significant: Berkshire raised the position by 45% from the prior quarter, while simultaneously trimming or holding other major stakes. This suggests deliberate capital reallocation into the search giant.

What does SteadyShares think of the valuation?

SteadyShares rates Alphabet at 76 out of 100, placing it in the solid but not exceptional range. The stock trades at roughly 41% below our estimated fair value estimate. This significant discount suggests either that the market is pricing in slower growth than our models assume, or that macroeconomic risks are depressing the multiple. Buffett's willingness to add aggressively into a position rated at a meaningful discount aligns with his historical pattern of building into quality businesses when prices allow.

Alphabet's separate Class C shares (GOOG), which lack voting rights and track the same business, saw an even more dramatic move: Berkshire boosted that position by 658% to $9.6 billion. Combined, the two share classes represent over 12.6% of the portfolio. SteadyShares rates GOOG at 85 out of 100, indicating higher conviction than GOOGL, though GOOG is typically held by smaller investors; the Class A shares are the preferred vehicle for institutions and long-term holders.

The bottom line

Berkshire's 45% addition to GOOGL and 658% boost to GOOG signals material conviction in Alphabet's durability and valuation at current prices. The filing shows action, not conviction as a philosophy, but the numbers themselves are clear: Berkshire allocated real capital here when it could have gone elsewhere.
