What is OKLO institutional ownership?
This page tracks OKLO positions reported by institutional investment managers through SEC Form 13F. OKLO INC (OKLO) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own OKLO?
InsiderSet currently tracks 628 institutional managers reporting OKLO 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 OKLO shareholders.
How much OKLO stock do institutions own?
Institutional investment managers disclosed approximately $4.31B in OKLO holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was OKLO institutional ownership last updated?
The latest OKLO 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 OKLO 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 OKLO position after the reporting date.
Are institutions buying or selling OKLO?
Institutional buying and selling can be analyzed by comparing OKLO positions across consecutive 13F reporting periods. InsiderSet's OKLO Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View OKLO ownership changes.
How has OKLO institutional ownership changed over time?
InsiderSet tracks OKLO institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
