IPO Alerts: How to Track S-1 Filings and Pre-IPO News Automatically
S-1 filings go live on EDGAR before anyone covers them. Pre-IPO secondaries, lock-up expirations, and investor roadshows leak before the offering. Here's how to catch it all.
When a company files its S-1 with the SEC, it's publicly visible on EDGAR within minutes. Most retail investors learn about it when a journalist writes about it — hours later, sometimes days. That gap is where the information advantage lives.
The IPO Information Timeline
Understanding where the signal is requires understanding the timeline:
- S-1 filing: Posted to SEC EDGAR, usually after market close. Publicly available immediately. Often not covered by financial media for hours.
- S-1/A amendments: Companies file amendments adding pricing ranges, updated financials, and roadshow details. Each amendment is another signal.
- Roadshow announcements: Institutional investor roadshows are announced in financial press and sometimes leaked through investor relations channels.
- Pricing and first-day performance: Final IPO price is set the night before trading begins. The pricing spread vs. the range signals institutional demand.
- Lock-up expiration: Insider lock-up expirations (typically 90–180 days post-IPO) are predictable events that often create selling pressure. Worth monitoring calendars for.

Pre-IPO Signals That Matter
Some of the most valuable pre-IPO signals don't come from SEC filings at all. Companies often do press around their last private round — "Series D at $X billion valuation" — which signals they're 12–24 months from an IPO. Executive hires with public company experience (a CFO with two prior IPOs, a head of investor relations) are strong predictors. Monitor these and you get a 6–12 month head start on the public filing.
Basically,
The S-1 is public the moment it's filed. Most investors wait for the media to tell them about it. You don't have to.
