What is EGHT institutional ownership?
This page tracks EGHT positions reported by institutional investment managers through SEC Form 13F. 8X8 INC (EGHT) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own EGHT?
InsiderSet currently tracks 171 institutional managers reporting EGHT 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 EGHT shareholders.

When was EGHT institutional ownership last updated?
The latest EGHT institutional ownership data on InsiderSet is based on SEC Form 13F filings for the quarter ended June 30, 2026.
