Methodology

We pull from six official sources, refreshed every hour, and we never mix them up with each other:

• SEC EDGAR: Registration statement filed with the U.S. Securities and Exchange Commission.
• Nasdaq IPO Calendar: Nasdaq's published calendar of upcoming and priced offerings.
• NYSE: New York Stock Exchange listings data.
• ASX: Australian Securities Exchange upcoming floats and listings.
• JPX: Japan Exchange Group new-listings page.
• Euronext: Euronext's IPO showcase — a record of companies that have already listed, not an advance-notice feed.

SEC filings tell us a company has registered to go public, but not whether the deal has actually priced yet — that detail only comes from the exchange itself. So when a company shows up in both an SEC filing and an exchange calendar, we use the exchange's numbers for price, status and timing, since it's the party that actually knows.

Not every company that files paperwork with the SEC is actually going public for the first time. We leave three kinds of listings out of our IPO tracker:

• Companies that already trade publicly and are simply registering to sell more shares — this isn't an IPO, so we don't show it as one.
• SPACs — shell companies that raise money with no business of their own, formed to later merge with a private company. We track operating businesses going public, not these.
• Funds and trusts — these are investment vehicles, not operating companies.

If a company's status changes — for example, it turns out to already be trading — we update our records automatically, so this list stays accurate without anyone having to fix it by hand.

Some company overviews on this site are written with the help of AI, and we always tell you which kind you're looking at:

• Filing summaries: when a company has filed an actual prospectus with the SEC, AI reads that document and summarizes it — the business, how it makes money, its strengths, its risks, and what it plans to do with the money it raises. Nothing is added that isn't in the filing.
• Researched overviews: for companies that only appear on an exchange calendar with no filing to summarize, AI researches the company from public sources instead. If it can't find anything reliable, we simply don't show an overview — we'd rather show nothing than guess.

Every overview is checked before it goes live — figures that look implausible or text that looks broken get caught and corrected, not published as-is. And every company page tells you exactly where its overview came from: the exchange, an SEC filing, or AI research.

We don't show market capitalization for companies that haven't listed yet — it doesn't really exist before a company sets its final share price, so instead we show the price range and offer size, which are genuinely published ahead of time. We also don't show a founding year, since none of our sources publish one reliably enough to trust. And we only show deal terms — price, shares, underwriters — once a company has actually disclosed them; many companies file to go public months before any of that is set.
