IPO Pipeline Tracker: New SEC S-1 & F-1 IPO Filings

Get every company that just filed to go public in the US, straight from official SEC filings. Each result is one S-1, F-1 or priced-IPO (424B4) filing with the proposed ticker and exchange, price range, shares offered, underwriters, a SPAC flag, plus the company's industry, address and phone. No API key, no login, no scraping of IPO calendar sites. The data comes from the SEC's public EDGAR system.

An S-1 is usually public weeks before an IPO prices and shows up on IPO calendars. This Actor gives you the raw, official filing the day it lands, cleaned into a row you can drop into a spreadsheet, a CRM, a Slack alert or a trading model.

What are S-1, F-1 and 424B4?

• S-1: the registration statement a US company files to sell shares to the public for the first time.
• F-1: the same form for foreign companies listing in the US.
• 424B4: the final prospectus filed when an IPO prices, with the final price and share count.

The Actor reads all three and, by default, keeps only first-time issuers (companies that had never filed a 10-K, 10-Q or 20-F before), so follow-on offerings and resale registrations from already-listed companies are dropped.

FAQ

Is this legal? Yes. Registration statements and prospectuses are public records published by the SEC on EDGAR. The Actor uses the SEC's official public index, filing files and submissions API, identifies itself with a User-Agent and contact email, and stays under the SEC's fair-access rate limit (10 requests per second).

How fresh is the data? Filings show up the same business day. The Actor reads the SEC's nightly daily index for past days and the EDGAR "latest filings" feed for today.

Why is the price range empty for some filings? Most companies file their first S-1 without a price range and add it in a later amendment (S-1/A) a week or two before pricing. Turn on Include amendments to catch it, and the 424B4 gives the final price.

How is "IPO" decided? A filing counts as an IPO when the company had not filed any 10-K, 10-Q or 20-F before it, and the filing isn't only a resale by existing holders. Turn IPOs only off to get every S-1 and F-1, including follow-ons.

How are the ticker, exchange and underwriters found? They're read from the prospectus cover and summary ("we intend to list ... under the symbol ..."). underwritersMentioned lists the banks named there. The prospectusUrl is always included so you can check the source.

Can I call it from code or an AI agent? Yes, through the Apify API, the Python/JS clients, or the Apify MCP server.

Can I get older data? Yes, set a Start date. EDGAR has registration statements going back to the 1990s.

Limits and notes

• Only the first part of each prospectus (the cover and summary) is read, so runs stay fast and cheap. A 14-day run usually finishes in about a minute.
• Offering size comes from the prospectus text when it's stated. The SEC fee table is now often a separate exhibit, so maxAggregateOfferingUsd can be empty.
• This Actor is not affiliated with or endorsed by the U.S. Securities and Exchange Commission.
