BRK-B vs IEP: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: IEP is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. BRK-B and IEP share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined BRK-B and IEP exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Berkshire Hathaway is a diversified holding company that owns a wide range of businesses outright and holds a large portfolio of public stocks. Its foundation is insurance: GEICO, Berkshire Hathaway Reinsurance, and other insurers generate underwriting profit and, more importantly, float (premiums held before claims are paid) that Berkshire invests. In Q1 2026 insurance underwriting income rose to about $1.72 billion from $1.34 billion a year earlier. Beyond insurance, Berkshire owns the BNSF railroad, Berkshire Hathaway Energy, and consumer and industrial businesses such as Duracell, Dairy Queen, See's Candies, and Precision Castparts, alongside a stock portfolio historically anchored by names like Apple and American Express.

Icahn Enterprises L.P. is a diversified holding company that trades as publicly listed limited-partnership units rather than corporate common stock. Its operating and investment segments span an Investment fund (Icahn's activist positions and hedges), Energy (anchored by a controlling stake in CVR Energy, a petroleum refiner and fertilizer maker), Automotive, Food Packaging, Real Estate, Pharma, and Home Fashion. The company's value is often framed by its indicative net asset value, which was roughly $3.4 billion as of March 31, 2026, and it reports results that can swing sharply with the performance of the Investment segment and the price of its large CVR Energy position. Carl Icahn and his affiliates owned approximately 86% of the outstanding depositary units at the end of 2025, so minority unitholders ride alongside Icahn's decisions.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• BRK-B drivers: Leadership transition to Greg Abel; Insurance float and underwriting.
• IEP drivers: Activist investing engine; Energy and CVR Energy exposure.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The central 2026 risk is the leadership transition itself: Buffett's judgment and reputation were core to Berkshire's edge, and the market will test whether Greg Abel can allocate capital as effectively, especially with a record cash pile to deploy. For IEP, the biggest risk is that the high distribution is not sustainable: IEP has cut its payout several times over the past decade, and a reduction can hit both income and the unit price at once.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick BRK-B if you believe its drivers more; IEP if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the BRK-B and IEP guides.

BRK-B. Figures are approximate and tied to the asOf date; verify live numbers before acting. Because accounting rules force Berkshire to mark its large stock portfolio to market each quarter, GAAP net income is noisy, so investors typically focus on operating earnings and book value per share rather than a simple P/E. The record cash balance means a meaningful part of the market cap is cash awaiting deployment, which affects how the business should be valued.

IEP. Figures are approximate and tied to the asOf date; verify live numbers before acting. IEP does not behave like a typical operating stock: its value is better judged against net asset value and distribution coverage than against an earnings multiple, because results swing with the Investment segment and CVR Energy. A double-digit headline yield usually signals that the market doubts the payout's durability, so treat the yield as a question rather than a guarantee, and always confirm the latest declared distribution and net asset value.

Headline figures (approximate, Jul 2026): BRK-B shows operating earnings (q1 2026) ~$11.35 billion, up ~18% year over year (approximate; verify live), net earnings (q1 2026) ~$10.1 billion, but volatile due to mark-to-market swings on equities (approximate; verify live), cash and treasurys ~$397 billion at end of Q1 2026, a record (approximate; verify live), market cap ~$1 trillion (BRK-B ~$497 per share in mid-July 2026; approximate; verify live); IEP shows structure Publicly traded limited-partnership units (K-1 tax form), not corporate common stock, indicative net asset value ~$3.4 billion as of March 31, 2026 (moves with the Investment and Energy segments), distribution Recently $2.00 annualized per unit ($0.50 per quarter); cash-or-units election, headline yield Very high (has been quoted above 20%); reflects both the payout and a depressed unit price.

BRK-B and IEP are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined BRK-B and IEP exposure against your real portfolio. It is not an investment adviser.
