$BRK-B 📊 Berkshire Hathaway: how much could it realistically be worth?

When people look at Berkshire, many focus on just a couple of things: Buffett, Apple, and the equity portfolio.

But in my view, Berkshire is much more than just “a holding with Apple shares.”

If we look at the company through a simple sum-of-the-parts lens, the numbers look very interesting.

The current market cap of BRK.B is roughly 1 trillion USD.

Of that, Berkshire holds approximately:

💵 391 billion USD in cash and T-bills

📈 288 billion USD in the equity portfolio

🏢 20 billion USD in other equity investments

Together that’s almost 699 billion USD in financial assets.

And then we have Berkshire’s operating businesses themselves:

🚗 Insurance / insurance franchise: approximately 40–60 billion USD

🚆 BNSF Railway: approximately 100–120 billion USD

⚡ Berkshire Hathaway Energy: approximately 55–75 billion USD

🏭 Manufacturing, Service & Retailing: approximately 150–180 billion USD

Conservatively, I estimate the operating businesses at roughly 345–435 billion USD.

When we put it all together, we get an estimated intrinsic value for Berkshire of about:

💎 1.04–1.13 trillion USD

So with a market cap around 1 trillion USD, Berkshire doesn’t strike me as extremely cheap, but rather a fair to mildly attractive value position.

And that’s, in my opinion, the point.

Recently Berkshire hasn’t outperformed the S&P 500. The market was driven mainly by big tech firms, the AI theme, and growth stocks. Berkshire, by contrast, is slower, more conservative, and less “sexy.”

Yet that’s exactly why it can be interesting today.

Not every position in a portfolio has to be a rocket. Some positions should protect capital, reduce volatility, and give the portfolio stability when the hype flips.

For me, Berkshire is interesting mainly as:

✅ a safer value position

✅ diversification outside tech

✅ a combination of cash, insurance, rail, energy, and industry

✅ a company with enormous financial strength

✅ a potential stabilizer for a portfolio

Historically Berkshire has been able to create extreme value. From 1965 to 2025, Berkshire had a CAGR of about 19.7%, while the S&P 500 was around 10.5%.

Of course, Berkshire is huge today and such returns are unlikely to repeat. But as a stable, diversified position outside the tech sector, it makes a lot of sense to me.

To me, Berkshire is more of a financial fortress than a rocket.

Not the sexiest stock on the market, but maybe that’s exactly why I like it.

This is not investment advice, just my view on Berkshire Hathaway’s valuation.
