This page tracks BRK-B positions reported by a curated group of notable institutional investors and fund managers through SEC Form 13F. BERKSHIRE HATHAWAY INC-CL B (BRK-B) on this page reflects disclosed 13F holdings among those superinvestors, not every institutional shareholder of the stock.
How many superinvestors hold BRK-B?
InsiderSet currently tracks 29 superinvestors reporting BRK-B holdings in the latest available 13F data. This is the curated set on this page, not the total number of institutions that own BRK-B.
How much BRK-B stock do superinvestors hold?
Superinvestors tracked by InsiderSet disclosed approximately $14.73B in BRK-B holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value, and it covers the curated superinvestors on this page rather than every institutional filer.
When were BRK-B superinvestor holdings last updated?
The latest BRK-B superinvestor holdings on InsiderSet are based on SEC Form 13F filings for the quarter ended June 30, 2026. Form 13F filings are generally reported after the quarter ends, so the holdings shown represent the latest publicly disclosed positions rather than real-time holdings.
Are superinvestor BRK-B holdings real-time?
No. Form 13F data is not real-time. It represents positions reported by these superinvestors as of the end of the reporting quarter. A superinvestor may have changed its BRK-B position after the reporting date.
