What is INBX institutional ownership?
This page tracks INBX positions reported by institutional investment managers through SEC Form 13F. INHIBRX BIOSCIENCES INC (INBX) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own INBX?
InsiderSet currently tracks 162 institutional managers reporting INBX 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 INBX shareholders.
How much INBX stock do institutions own?
Institutional investment managers disclosed approximately $1.28B in INBX holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was INBX institutional ownership last updated?
The latest INBX 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 INBX 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 INBX position after the reporting date.
