No insider purchase over the last 90 days. The latest, by Jacobs Ian Seth, was filed 28 Aug 2025.
Deep Fission, Inc.: what insiders have been doing
Deep Fission, Inc. belongs to the Industrials sector. Filings by its managers are published through SEC (Form 4). 1 insider has disclosed 1 filing since 26 October 2025.
None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.
Compared with its exchange (3,167 companies, median 24 filings), a count of 1 filing is below the norm. Over the whole record (from 2025), the tally stands at 1 purchase and 1 sale. On the fundamentals side, the SEC filing (10-K) for the period ending 31 December 2025 lists net income at -61.0 m USD.
No insider has bought Deep Fission, Inc. shares on the open market in the past twelve months.
Other companies in the same sector with recent insider buying flagged by our signals: Bolloré SE and Auroora Yhtiöt Oyj. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
