What is RBRK institutional ownership?
This page tracks RBRK positions reported by institutional investment managers through SEC Form 13F. RUBRIK INC-A (RBRK) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own RBRK?
InsiderSet currently tracks 585 institutional managers reporting RBRK 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 RBRK shareholders.
How much RBRK stock do institutions own?
Institutional investment managers disclosed approximately $10.28B in RBRK holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was RBRK institutional ownership last updated?
The latest RBRK 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 RBRK 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 RBRK position after the reporting date.
Are institutions buying or selling RBRK?
Institutional buying and selling can be analyzed by comparing RBRK positions across consecutive 13F reporting periods. InsiderSet's RBRK Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View RBRK ownership changes.
How has RBRK institutional ownership changed over time?
InsiderSet tracks RBRK institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
