Who owns GigCapital9 Corp., from the filings themselves: stakes over 5% (Schedule 13D/G), the institutional managers reporting the stock each quarter (13F), and the funds holding it (N-PORT).
Investors crossing 5% ownership must disclose it. Schedule 13G filers certify the stake is passive; Schedule 13D is the general form for everyone else — founders, strategic holders, and activists alike. Each entry is the holder's most recent disclosure. Coverage begins with SEC's structured filings from December 18, 2024; a holder appears once they file or amend after that date.
