What is ODTX institutional ownership?
This page tracks ODTX positions reported by institutional investment managers through SEC Form 13F. Odyssey Therapeutics, Inc. (ODTX) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own ODTX?
InsiderSet currently tracks 58 institutional managers reporting ODTX 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 ODTX shareholders.
How much ODTX stock do institutions own?
Institutional investment managers disclosed approximately $638.06M in ODTX holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was ODTX institutional ownership last updated?
The latest ODTX 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 ODTX 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 ODTX position after the reporting date.
