IPO AND NEW LISTING DATA
Every US IPO, linked to the security from day one.
IPO data in one dataset, keyed to the ASID, so the offering record follows the security through every event after it. Most IPO sources scatter the pieces, none of them linked to what came next.

Connected from the first trade
An IPO record that does NOT break the moment the company changes.
Most IPO datasets give you a snapshot and leave it there: the ticker changes, the company merges, and the record sits in a silo. Keyed to the ASID, the offering stays one join from the full equity history no matter what changes afterward.
Linked to the ASID
Every IPO record connects to the same persistent identifier used across the security master, tick data, and adjustment factors. One join, no mapping tables.
Two granularity levels
The basic dataset covers every new listing with the essentials. The detailed dataset adds underwriter, deal type, pricing range, and initial listing price.
Every US exchange
NYSE, Nasdaq, and every other US equity exchange. No gaps from exchange-specific sourcing.

Why it matters
IPO data without a persistent identifier is a dead end.
A standalone IPO feed
Keyed to the ticker at listing, which may change within months.
No link to the security master, so joining the IPO to subsequent corporate events requires manual reconciliation.
Listing price only, with no underwriter, deal type, or pricing range context.
algoseek IPO data
Keyed to the ASID, which follows the security through every ticker change, merger, and delisting.
One join to the security master, tick data, bars, and adjustment factors. No mapping tables.
Two granularity levels, from bare coverage to full offering detail.
Take just the IPO data if that is all you need, or get it inside the Equities Package or Multi-Asset Package, alongside the security master, tick data, bars, and adjustment factors under one license.
