Private Venture Mega-Raise Money ($100M+): U.S. (SEC Form D)

## What this measures

The money in raises of $100 million or more in each calendar quarter, in billions of U.S. dollars.

## Why it matters

How much of private raising happens at the very top. Read against the total (capital.form_d.venture_amount_sold.us) for the share the big rounds take.

## How it is made

Every company that sells securities under Rule 506 of Regulation D files a notice, Form D, with the SEC within 15 days of the first sale, and amends it at least once a year while the offering runs. The SEC's Division of Economic and Risk Analysis publishes every notice as filed in quarterly data sets (2009 onward). Palanor loads all of them. An offering is its SEC file number (an amendment, Form D/A, keeps the number of the notice it amends), and each filing reports the total sold so far, so the money a filing adds is its total minus the previous filing's.

**Venture-like offerings** are equity (alone or with debt, options or other securities) sold under Rule 506 by a U.S. private operating company: no pooled-fund interests, no funds or deal vehicles, no banks, investment vehicles, oil and gas, coal or real estate, no limited partnerships or business trusts, no registered investment companies, no business combinations, and no company that was already an SEC reporting company. Offerings with a filing that adds $1 billion or more count only after a hand review (typing errors such as $105 billion for a $105 million round are dropped). The full rule list is in the Palanor code (src/lib/form-d/venture.ts), the same definition as Palanor's other Form D series. **A raise** is the money one offering adds in a calendar quarter: the sum of what its filings dated in that quarter add. A new round is usually one raise; an offering that keeps selling and reports more on an amendment adds a second raise in the later quarter.

## How to read it

A quarterly level that a single very large round can move by billions.

## What it does not cover

Form D is a notice of an exemption, not an announced funding round. Companies that raise without Rule 506, or file late or never, are missing, and some of the largest private companies raise without a notice of their own (only their investor vehicles file). Amounts are what companies report as sold, in the quarter the notice is filed, not when the money was wired. The industry group, state and fund type are the filer's own answers on the form and are not checked. The largest AI developers raise mostly without a Form D of their own, so the biggest rounds of all are often missing.
