How the total is counted: the amount sold on each new offering, added together. Amendments are left out, because an amendment restates an offering already counted. A filing whose figures have not been read yet shows a dash and adds nothing.

Every figure here is read from DEEP FISSION, INC.'s own filings with the SEC. The people those filings name are on the team page.
