What is OKE institutional ownership?
This page tracks OKE positions reported by institutional investment managers through SEC Form 13F. ONEOK INC (OKE) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own OKE?
InsiderSet currently tracks 867 institutional managers reporting OKE 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 OKE shareholders.
How much OKE stock do institutions own?
Institutional investment managers disclosed approximately $40.23B in OKE holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was OKE institutional ownership last updated?
The latest OKE 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 OKE 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 OKE position after the reporting date.
Are institutions buying or selling OKE?
Institutional buying and selling can be analyzed by comparing OKE positions across consecutive 13F reporting periods. InsiderSet's OKE Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View OKE ownership changes.
How has OKE institutional ownership changed over time?
InsiderSet tracks OKE institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
