IPO filings › About this data
IPO filings
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 This feed follows each offering through those steps and shows where it stands: filed, amended, priced or withdrawn.
- Where it comes from
Forms S-1, F-1, 424B4 and RW that companies send to the SEC and the SEC publishes on EDGAR.
Who reports it: The company, usually through its law firm. The SEC's file number (333-...) ties together every filing for one offering.

- Coverage
- Filings from January 2015 to today. 35 filings in that span are left out on purpose: 28 the SEC lists but no longer serves (withdrawn) and 7 that were re-typed as shelf registrations (Form S-3).
- 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.
