The U.S. Equities IPO (Detailed) dataset provides comprehensive reference information on Initial Public Offering (IPO) events for equities listed on U.S. public exchanges, excluding securities traded on the OTC market. Like the basic IPO dataset, records are typically available several days prior to the first trading day, enabling early identification and monitoring of upcoming offerings. Core fields include ticker symbol, algoseek SecId, ISIN, first trading date, and IPO status indicators that track outcomes such as completed, postponed, or otherwise modified offerings. In addition to these core attributes, the detailed dataset includes expanded offering-level metadata, such as par value, initial offering price, and underwriter information. This enhanced field coverage supports deeper analysis of IPO structure, pricing context, and issuance characteristics, and is well suited for research, security master enrichment, and historical event analysis.

For more details, please refer to the dataset documentation: US Equities IPO Detailed Guide.
