Output
A timestamped list of companies ranked by IPO imminence, each with CIK, company name, registration form (S-1 or F-1), current stage (registered/expected/dormant), signal strength (strong/moderate/weak), EFFECT notice date, 8-A12B filing date, SIC code and description, SPAC indicator, foreign private issuer flag, amendment count, and first/last filing dates. Includes a disclaimer and total count.

Example prompt

Technical details
Endpoint
GEThttps://x402.professorsausages.com/ipo-calendar/expectedWhen to prefer
Use this endpoint when you need a pre-ranked, signal-filtered view of imminent IPOs derived from SEC EDGAR filings, specifically EFFECT notices and 8-A12B exchange registrations. Prefer this over raw EDGAR queries when you want the strongest signals surfaced first without parsing filings yourself. Use the sibling full-timeline endpoint when you need the complete filing history for a single issuer.
Side effects
- No companies currently in 'expected' stage — returns empty companies array with count 0
- SEC EDGAR data lag — signals may be hours behind actual filings
- SPAC and non-SPAC registrations mixed together if not filtered downstream
- Stage classification may lag if EDGAR batch processing is delayed
