When did Jacob Dewitte buy into Oklo Inc.?
The filings give report dates, not purchase dates. The earliest filing from Jacob Dewitte on this page is the Schedule 13D/A, filed 2025-07-02, reporting 16.2%; its latest, Schedule 13D/A filed 2026-07-06, reports 11.1%. That earliest filing is itself an amendment, which updates an earlier report.

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%); 9 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.
