The short version
- Berkshire Hathaway's Form 13F for the quarter ending 2026-06-30 (filed 2026-08-14) reports 29 US-listed positions worth $299.25 billion. The March filing reported 29 positions worth $263.10 billion; the difference is mostly price.
- Apple is 22.0%, American Express 17.1%, Coca-Cola 10.9%. The two Alphabet share classes together are 12.6%, Bank of America 9.2%. The top ten are 88.5% of the reported value and the list behaves like 8.6 equally weighted holdings — more concentrated than SMH (26 holdings, behaves like 13.9) or XLK (78, behaves like 16.3).
- Share counts changed in 13 positions. The largest by value: Alphabet Class A +45.2% (54.2 million to 78.8 million shares) and Class C +658% (3.6 million to 27.2 million); Bank of America −5.9%; Delta Air Lines +44.0%; Kroger −22.0%; Capital One −58.0%; Nucor −52.5%. One position was closed (Constellation Brands, 0.04%) and one opened (D.R. Horton, 3,564 shares — a rounding error at this scale).
- Apple, American Express, Coca-Cola, Chevron, Occidental, Chubb, Moody's and Kraft Heinz did not move by a single share.
- A 13F is not a portfolio. It omits everything that is not a US-listed security: Berkshire's Japanese trading-house stakes, its wholly owned operating businesses, its Treasury bills and cash, and any trade after 30 June. It is filed by the registrant; it does not say which of Berkshire's investment managers made any decision.

How concentrated 8.6 is
Effective holdings is one divided by the sum of squared weights — the number of equal-sized positions that would give the same concentration. It is the measure this site applies to every fund from its N-PORT filing, and it applies to a 13F information table in exactly the same way.
| Portfolio | Reported holdings | Behaves like | Top ten |
|---|---|---|---|
| Berkshire Hathaway 13F, 2026-06-30 | 29 | 8.6 | 88.5% |
| Berkshire Hathaway 13F, 2026-03-31 | 29 | 8.4 | 90.7% |
| SMH (VanEck Semiconductor) | 26 | 13.9 | 70.2% |
| XLK (Technology Select Sector) | 78 | 16.3 | 64.5% |
| QQQ | 105 | 34.2 | 45.0% |
| VOO | 513 | 51.5 | 36.4% |
Five positions — Apple, American Express, Coca-Cola, the two Alphabet classes together, and Bank of America — are 71.9% of the reported value. That is why the list behaves like fewer than nine holdings although it has 29 lines. The quarter's changes moved the figure from 8.4 to 8.6, marginally less concentrated, because value was added to Alphabet (the fourth and tenth lines) rather than to the top three.
What moved, and what did not
Read the share column, not the value column: a value that rises with an unchanged share count is a price move, not a purchase.
- Added: Alphabet Class A +24.5 million shares and Class C +23.6 million shares; Delta +17.5 million; Lennar A +3.0 million; Macy's +4.3 million; New York Times +0.55 million; D.R. Horton opened at 3,564 shares.
- Reduced: Bank of America −30.2 million shares; Kroger −11.0 million; Capital One −4.15 million; Nucor −2.05 million; Ally −2.0 million; DaVita −1.2 million.
- Unchanged: the top three, Chevron, Occidental, Chubb, Moody's, Kraft Heinz, SiriusXM, VeriSign, both Liberty Live series, Louisiana-Pacific, NVR, Jefferies.
Total reported value rose $36.2 billion (+13.7%) between the two filings. The net share activity above is small next to that; most of the increase is the prices of positions that did not change.
What a 13F cannot tell you
- It is US-listed long positions only. Berkshire's stakes in the five Japanese trading houses, held on the Tokyo exchange, are not in it. Neither are its wholly owned businesses (insurance, railroad, energy, manufacturing), which are most of Berkshire, nor its Treasury bills and cash, which appear on Berkshire's balance sheet and not on any 13F. The 13F is a slice, not the whole.
- It is 45 days late by design and describes 30 June. Anything traded in July, August or September is not here.
- It does not name a decision-maker. Berkshire has more than one investment manager; the filing is the registrant's. Calling it one person's portfolio adds a claim the document does not make, which is why this site does not.
- Confidential treatment can hold a position back from a 13F with SEC permission; if one was withheld this quarter it would appear in a later amendment. We have not checked for amendments after 2026-08-14.
