What is BRK-A institutional ownership?
This page tracks BRK-A positions reported by institutional investment managers through SEC Form 13F. BERKSHIRE HATHAWAY INC-CL A (BRK-A) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own BRK-A?
InsiderSet currently tracks 1,395 institutional managers reporting BRK-A holdings in the latest available 13F data. This count reflects institutions included in the SEC Form 13F filings analyzed by InsiderSet and should not be interpreted as the total number of BRK-A shareholders.
How much BRK-A stock do institutions own?
Institutional investment managers disclosed approximately $60.33B in BRK-A holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was BRK-A institutional ownership last updated?
The latest BRK-A institutional ownership data on InsiderSet is 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 institutional holdings.
Are institutional BRK-A holdings real-time?
No. Form 13F data is not real-time. It represents positions reported by institutional investment managers as of the end of the reporting quarter. An institution may have changed its BRK-A position after the reporting date.
Are institutions buying or selling BRK-A?
