Questions about who owns Spark I Acquisition Corp
Who owns Spark I Acquisition Corp?
On this page, one holder's latest ownership filing reports 5% or more of Spark I Acquisition Corp: AQR Capital Management, LLC (7.02%, Schedule 13G/A, filed 2026-08-14).
When did AQR Capital Management, LLC buy into Spark I Acquisition Corp?
The filings give report dates, not purchase dates. The earliest filing from AQR Capital Management, LLC on this page is the Schedule 13G/A, filed 2025-08-06, reporting 10.17%; its latest, Schedule 13G/A filed 2026-08-14, reports 7.02%. That earliest filing is itself an amendment, which updates an earlier report.
Is this an audit or a full list?
Neither. The ownership list on this page covers only Schedule 13D and 13G filings, which holders make once they own 5% or more of a class of shares (an amendment can report a stake that has since fallen below 5%); 11 such filings are shown here. It is not an audit and not a full cap table: holders who never reached 5% are not listed, and a stake can change after its latest filing.

Where this comes from
Anyone who comes to own more than 5% of a class of a listed company's voting shares has to tell the SEC. A holder who may seek to change or influence the company files Schedule 13D, and has to say in Item 4, "Purpose of Transaction", what it intends to do. A holder with no such intent, such as many index and passive funds, may file the shorter Schedule 13G. Both are amended when the stake changes, including when it falls below 5%.
Every row here is one of those filings, linked to the filing itself. Percentages and share counts are exactly as the holder filed them, for the holder the filing names; an amendment showing a lower figure is shown as filed. Item 4 text is quoted word for word. Where a 13D's Item 4 contains a sentence stating a definite intent to influence the company, that sentence is marked and quoted; the page does not describe the holder or its motives beyond the words it filed. Nothing here is investment advice.
