What is SLNH institutional ownership?
This page tracks SLNH positions reported by institutional investment managers through SEC Form 13F. SOLUNA HOLDINGS INC (SLNH) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own SLNH?
InsiderSet currently tracks 103 institutional managers reporting SLNH 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 SLNH shareholders.
How much SLNH stock do institutions own?

When was SLNH institutional ownership last updated?
The latest SLNH 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.
