Welcome, fellow investor! Are you curious about the financial giants that shape our world? You've come to the right place. Today, we're going to dive into a fascinating question: how much of Berkshire Hathaway does BlackRock own? It's a question that gets at the heart of modern investing, where massive asset managers hold significant stakes in some of the most iconic companies.
Let's embark on this journey together to understand the intricate web of institutional ownership and what it means for a company as legendary as Warren Buffett's Berkshire Hathaway.
Step 1: Understanding the Landscape of Institutional Ownership
Before we get to the specifics of BlackRock and Berkshire, let's understand the players. Imagine a massive, global investment firm like BlackRock as a powerful river. This river is made up of countless smaller streams—the money from millions of investors like you and me. These streams flow into various investment vehicles, such as mutual funds and exchange-traded funds (ETFs), which BlackRock manages.
Now, a company like Berkshire Hathaway is a giant, majestic tree. Its shares, both the super-expensive Class A (BRK.A) and the more accessible Class B (BRK.B), are like the leaves on its branches. Institutional investors, like BlackRock, own a huge portion of these leaves, representing the collective investments of their clients. So, when we talk about BlackRock's ownership, we're not talking about a single individual at BlackRock deciding to buy shares; we're talking about the holdings of thousands of funds and accounts that BlackRock oversees on behalf of its clients.

Step 2: Finding the Data: A Guide to Public Filings
How do we even find this information? The key lies in public filings. In the United States, large institutional investment managers like BlackRock are required to file quarterly reports with the Securities and Exchange Commission (SEC). The most relevant document for this purpose is the Form 13F, which discloses their equity holdings.
QuickTip: Compare this post with what you already know.
Sub-heading: Deciphering the 13F Filing
A 13F filing is like a snapshot of a large money manager's portfolio at the end of each quarter. It lists all the stocks they hold with a market value of over $100 million. This is where we find the crucial information about their holdings in companies like Berkshire Hathaway. These filings are publicly available on the SEC's EDGAR database, and financial data websites often compile and analyze this data to make it easier to understand.
This is a dynamic process. These firms are constantly buying, selling, and holding shares, so the percentage of ownership can change from one quarter to the next.
Step 3: The Big Reveal: How Much Does BlackRock Own?
Based on recent institutional ownership data from financial platforms that track 13F filings, we can get a clear picture.
As of the most recent available data, BlackRock is one of the top institutional shareholders of Berkshire Hathaway. While the exact number of shares and the percentage of ownership can fluctuate based on market activity and new filings, recent reports consistently show BlackRock's significant stake.
According to data from around the end of Q1 2025, BlackRock, Inc. held over 111 million Class B (BRK.B) shares of Berkshire Hathaway.
To put that into perspective, this holding represents a substantial percentage of the total outstanding Class B shares. It's important to note that the ownership is primarily in the more liquid Class B shares, as the Class A shares are incredibly expensive and less frequently traded.

Step 4: Who are the Other Major Players?
While BlackRock's holding is impressive, it's not the only one. Berkshire Hathaway has a concentrated ownership structure, with a few key players holding a significant portion of the company.
Warren Buffett: The Oracle of Omaha himself is the single largest shareholder, holding a massive amount of Class A and Class B shares, which gives him significant voting power and control. His ownership is a testament to his long-term conviction in the company he built.
The Vanguard Group: Another behemoth in the asset management world, Vanguard is often a larger institutional shareholder than BlackRock in many companies, and this holds true for Berkshire Hathaway as well.
State Street Corp: Another major institutional investor, State Street also holds a substantial position in Berkshire.
These institutional investors, including BlackRock, hold shares on behalf of a vast number of clients through their index funds, ETFs, and other managed portfolios. This means that millions of people who invest in a total market index fund or an S&P 500 ETF through these firms are indirectly owners of a piece of Berkshire Hathaway.
Step 5: Why is this Ownership Important?

The concentration of ownership in the hands of a few large institutional investors has several implications:
Influence on Corporate Governance: While Warren Buffett's control over Berkshire is paramount, the collective voice of large institutional shareholders can still be influential. They often have the power to vote on key proposals at annual shareholder meetings, even if they don't have a controlling stake.
Stability of the Stock: Large, long-term holdings by institutional investors can contribute to the stability of a company's stock price. They are less likely to engage in rapid buying and selling, which can reduce volatility.
Reflection of Investment Philosophy: The fact that these massive, passive fund managers hold Berkshire Hathaway is a testament to the company's inclusion in major market indexes like the S&P 500. It shows that Berkshire is a well-established and important component of the overall market.
In summary, while BlackRock's ownership of Berkshire Hathaway is significant, it's part of a larger picture where a handful of asset management giants hold substantial stakes, and a majority of the voting power remains with its legendary founder, Warren Buffett.
