IPO filings

What it is

A company that wants to sell its shares to the public for the first time registers the offering with the SEC, on Form S-1 or, for a foreign company, Form F-1. It then files amendments as the SEC reviews it. When the shares are priced it files the final prospectus (Form 424B4), and a company that changes its mind files a withdrawal (Form RW). This feed follows each offering through those steps and shows where it stands: filed, amended, priced or withdrawn.

Who files it

The company, usually through its law firm. The SEC's file number (333-...) ties together every filing for one offering.

How current

We collect new filings every night, once the SEC has finished its index for the day.

Terms

S-1The form a company in the US files to register shares it plans to sell to the public. It describes the business, the risks and how the money will be used.F-1The same registration for a company based outside the US.424B4The final prospectus, filed once the offering is priced. It states the price per share and how many shares are being sold.RWA request to withdraw a registration. The company is telling the SEC it will not go ahead with that offering, at least for now.

Worth knowing

Many S-1s are not IPOs: companies that already trade file them to register resales or a new offering. We show registrations whose prospectus says it is an initial public offering; change Show to see the rest. A registration is not a promise to list, and many are never priced. Max registered is the ceiling the company put in the SEC's filing-fee table, often a round placeholder, not the amount raised; the table is machine-readable only for filings since mid-2025, so older rows show a dash. Amount raised is price times shares from the final prospectus and stays blank until the offering is priced. When the prospectus does not clearly name a ticker, we leave it blank rather than guess.

All of this comes from public filings.
