How Big is the Berkshire Hathaway Fund? A Deep Dive into Warren Buffett's Investment Empire
Have you ever wondered what it would be like to manage one of the world's largest and most successful investment funds? Imagine having a "war chest" of billions of dollars, ready to deploy into companies that you believe in for the long haul. That's the reality for Warren Buffett and his team at Berkshire Hathaway. It's not just a fund; it's a colossal conglomerate with a sprawling empire of wholly-owned businesses and a massive portfolio of publicly traded stocks. So, just how big is this fund? Let's break it down, step by step, and explore the different facets of Berkshire's immense size and influence.

Step 1: Get a Grip on the Different Components of the Berkshire Hathaway "Fund"
First, let's address a common misconception. Berkshire Hathaway isn't a traditional mutual fund or ETF that you can simply invest in. It's a publicly traded holding company that owns a vast collection of businesses and a huge portfolio of stocks. When we talk about the "Berkshire Hathaway fund," we're really talking about two main components that give it its immense size:
The Publicly Traded Equity Portfolio: This is what most people think of when they hear "Berkshire Hathaway's investments." It's the collection of stocks in companies like Apple, Coca-Cola, and American Express that Berkshire owns and discloses in its quarterly 13F filings with the SEC.
The Wholly-Owned Businesses: This is the often-overlooked but equally significant part of Berkshire's empire. These are businesses that Berkshire owns outright, such as GEICO, BNSF Railway, and Dairy Queen. Their value is not reflected in the public stock portfolio but is a core part of Berkshire's overall value and earnings.
So, when you ask "how big is the Berkshire Hathaway fund?", you need to consider both of these massive pieces. The size of the fund is dynamic, changing with market fluctuations, new acquisitions, and investment sales. However, we can look at some key metrics to get a sense of its incredible scale as of mid-2025.
Step 2: Unpack the Enormous Stock Portfolio
Let's dive into the publicly traded stock portfolio, which is the most visible part of Berkshire's investments. As of the first quarter of 2025, the value of this portfolio was approximately $258 billion. Now, that's a mind-boggling number, but what's even more fascinating is how that money is allocated.
Concentration and Conviction: The Top Holdings
Warren Buffett is famous for his "concentrated portfolio" approach, believing that diversification is for those who don't know what they're doing. This philosophy is clearly reflected in Berkshire's holdings. A staggering majority of the portfolio's value is concentrated in a handful of companies.
Reminder: Reading twice often makes things clearer.
Apple (AAPL): The tech giant remains Berkshire's largest holding by a significant margin. Despite some recent trimming of the position, it still accounts for around 26% of the total equity portfolio. As of March 31, 2025, this stake was valued at approximately $66.6 billion.
American Express (AXP): A long-time favorite of Buffett's, this financial services company makes up about 16% of the portfolio, with a value of over $40 billion.
Coca-Cola (KO): Another classic Buffett stock, this beverage behemoth represents over 11% of the portfolio, valued at around $28 billion. Buffett has held this stock for decades, a testament to his long-term buy-and-hold strategy.
Bank of America (BAC): Although Berkshire has been reducing its stake in this bank, it still holds a substantial position, valued at around $26 billion, making up over 10% of the portfolio.
Chevron (CVX): This energy giant is a more recent addition to Berkshire's top holdings and accounts for nearly 8% of the portfolio, with a value of almost $20 billion.
These top five holdings alone represent roughly 70% of Berkshire's entire publicly traded equity portfolio. This is a powerful demonstration of Buffett's investment philosophy: bet big on what you know and trust for the long term.
Recent Moves and Shifts
Berkshire's portfolio is not static. The team is always on the lookout for new opportunities and may trim or eliminate positions. In the first quarter of 2025, they made some notable changes:
New Buys: Berkshire revealed a significant new stake in Constellation Brands (STZ), acquiring over 12 million shares worth more than $2 billion. They also increased their holdings in Domino's Pizza (DPZ) and Pool Corporation (POOL).
Reductions & Exits: Berkshire completely exited its position in Citigroup (C) and significantly reduced its stake in Bank of America (BAC), T-Mobile US (TMUS), and Capital One Financial (COF).
These moves reflect a strategic pivot, as Buffett and his team rotate out of some financial stocks and into more stable, cash-generative businesses like consumer staples and energy.
Step 3: Consider the Massive Cash Pile
This is perhaps one of the most remarkable aspects of the Berkshire Hathaway "fund." At the end of the first quarter of 2025, Berkshire was sitting on a record $347 billion in cash and cash equivalents. This is an unprecedented amount of liquidity for a public company, and it provides an enormous "war chest" for future acquisitions, investments, and share buybacks.
Why so much cash? Buffett has a simple and powerful reason: he believes in having ample cash reserves to weather any economic storm and to be able to seize opportunities when the market is in turmoil. He prefers to wait for a "fat pitch" – a truly great company available at a reasonable price – rather than overpaying for a business.
More cash than giants combined: To put this into perspective, Berkshire's cash holdings are more than the combined cash reserves of tech giants like Apple, Microsoft, Alphabet, Amazon, and NVIDIA. This is a testament to the company's financial discipline and its ability to generate massive amounts of cash from its diverse operating businesses.
Step 4: Don't Forget the Wholly-Owned Businesses
While the stock portfolio gets most of the attention, the foundation of Berkshire Hathaway is its collection of wholly-owned businesses. These are companies that Berkshire owns 100%, and their value is not included in the public stock portfolio figures. These businesses provide a steady stream of earnings and cash flow, which is then used to fund new investments and acquisitions.
These include a wide range of industries:
Tip: Slow down at important lists or bullet points.
Insurance: GEICO, General Re, and Berkshire Hathaway Primary Group are key players.
Railroad: BNSF Railway is one of the largest freight railroads in North America.
Utilities and Energy: Berkshire Hathaway Energy owns electric and gas utilities.
Manufacturing, Service, & Retail: This is a diverse group that includes businesses like Dairy Queen, Duracell, and Fruit of the Loom.
The value of these businesses is a significant part of Berkshire's overall market capitalization, which currently stands at over $1 trillion. This market cap is a reflection of the combined value of all of Berkshire's assets, including the stock portfolio, the wholly-owned businesses, and the massive cash pile.

Step 5: Putting It All Together - The Final Size
So, how big is the Berkshire Hathaway fund? When you combine all the pieces, you get a truly staggering picture. As of mid-2025, we can estimate the size of the Berkshire Hathaway empire to be:
Publicly Traded Equity Portfolio: ~$258 billion
Cash and Cash Equivalents: ~$347 billion
Wholly-Owned Businesses: A substantial portion of the company's ~$1 trillion market capitalization.
This makes Berkshire Hathaway a financial powerhouse unlike any other. Its sheer size, coupled with its disciplined, long-term investment approach, makes it a unique and formidable force in the global economy.
