Defense-tech funding rounds

Defense-technology securities offerings, each figure read from the issuer's own filing and published with the verbatim source text behind it. Amount sold and amount offered are separate columns because Form D reports both and they routinely differ by hundreds of millions of dollars.

This tracker holds 5 defense-technology securities offerings, 5 of which state an amount sold. Those 5 account for $932,252,497 in securities sold. 4 of the 5 also state the total amount the issuer authorised, which is a different number and is kept in its own column: collapsing the two is how a $347,799,797 sale becomes a “$600 million round”. The largest single offering here is Saronic Technologies, Inc., at $347,799,797 sold. First-sale dates run from 2023-09-13 to 2025-05-09. Every figure is read from the issuer’s own filing and stored with the element it came from, quoted verbatim, so any row on this page can be checked against the document behind it. The Round column is empty on every row, and that is the finding rather than a gap: Form D carries no round label, and an inferred one published as structured data is a fabricated fact with a long half-life. Amendments restate rather than add, so a filing superseded by a later one is held out of this table instead of being summed into it. The rules that decide what may be published are on the methodology page.

totalOfferingAmount reads "Indefinite", which states no number: the field is absent rather than zero.

Source and methodology

Each figure is read from the issuer's own Form D primary document on SEC EDGAR and stored with the element it came from, quoted verbatim. Nothing is inferred: Form D carries no round label and names no investors, so those fields stay empty rather than being filled in from press coverage.

Scope. United States.

What each column means

Company
Issuer name exactly as it appears in the filing. It is not always the trading name a reader knows: Castelion Corp's seed round was filed by Pallas Industries, Inc.
Amount sold (USD)
Securities sold as of this filing (Form D totalAmountSold). Money that has actually closed.
Amount offered (USD)
The total offering amount the issuer authorised (Form D totalOfferingAmount). A ceiling, not a receipt.
Round
Seed, Series A and so on. Empty on every filing-only row: Form D carries no round label, and publishing an inferred one as structured data is a fabricated fact with a long half-life.
First sale
Date of first sale as stated in the filing. Not the announcement date, which Form D does not contain.
Filed
The date EDGAR recorded the filing.
