About This Website

Transparent data, simple exploration.

Berkshire Holdings is an informational website designed to make publicly reported Berkshire Hathaway holdings easier to explore, search, compare, and understand.

Important data limitation The current website dataset contains a limited number of independently verified holdings from the June 30, 2026 Form 13F-HR. The SEC filing reports 89 entries, so the currently displayed dataset should not be interpreted as the complete filing.

What this website does

The purpose of Berkshire Holdings

This website organizes publicly reported Berkshire Hathaway securities into a searchable and easier-to-navigate interface.

Instead of requiring users to work directly through regulatory filing documents, the website provides portfolio tables, individual security pages, dashboards, historical references, and filing documentation.

The website is designed as an informational research tool. It does not attempt to tell users which investments they should buy, sell, or hold.

Methodology

How the website handles reported holdings

1

Start with regulatory filings

SEC filings are used as the primary source for reported 13F holdings.

2

Identify the reporting period

Each holding is associated with the reporting period stated by the relevant filing.

3

Preserve reported values

Share counts and reported values are displayed according to the filing data rather than substituted with live market prices.

4

Avoid unsupported assumptions

Information that has not been verified is not presented as fact. This includes unverified sector classifications and incomplete holdings data.

5

Link back to the source

Filing information is provided so users can inspect the original SEC source themselves.

What the numbers mean

A reported value is the value reported in the filing for the relevant reporting period. It is not necessarily the current market value of the security.

Share counts represent the shares reported in the filing. They should be interpreted together with the security class and reporting date.

The site does not treat a 13F as a complete representation of every asset Berkshire Hathaway owns.

What this website does not provide

It does not provide personalized investment advice.

It does not claim that Warren Buffett personally owns every security reported by Berkshire Hathaway.

It does not treat historical filing data as real-time portfolio information.

Filing coverage

The current dataset does not yet contain all entries from the referenced 89-entry filing. Additional verified entries can be added later.

Reporting delay

Form 13F information describes holdings at a previous reporting date, not necessarily what the manager owns at the exact moment a user views this website.

Security scope

Form 13F reporting requirements cover specified securities and therefore should not be treated as a complete balance sheet of Berkshire Hathaway's assets.

Source verification

Users should consult the original SEC filing when they need the authoritative regulatory document or need to verify a particular entry.
