What is GLW institutional ownership?

How many institutions own GLW?
InsiderSet currently tracks 2,467 institutional managers reporting GLW 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 GLW shareholders.

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