IPOS

IPO filings with pricing, offering size, underwriters, lockup periods, and financials

Overview

The IPO dataset provides structured data extracted from SEC registration filings — S-1 and 424B4 prospectuses — for companies that have gone public in the US. Each record covers a single company's offering, consolidating pricing, share structure, underwriter syndicate, lockup terms, and last fiscal year financials into a single row.

Use Cases

  • Deal Tracking — Monitor new listings with offer price, exchange, and offering size
  • Underwriter Analysis — Track lead and co-managers across deals by bank
  • Pre-IPO Research — Access price range and financial profile before a deal prices
  • Quantitative Research — Build datasets of historical IPO characteristics for backtesting
