Nasdaq Private Market (NPM) operates infrastructure for the secondary market in pre-IPO private company equity — tender offers, company buybacks, auctions, block trades and a settlement engine for private share transfers — alongside a Data & Intelligence business built on NPM Price, a daily price estimate for 400+ liquid private companies, and Tape D, a private-company pricing dataset combining primary round data, secondary market transactions, mutual fund marks and 409A valuations. Securities are offered through NPM Securities, LLC (member FINRA/SIPC); SecondMarket Financial, LLC is an SEC-registered investment adviser and wholly owned subsidiary. Programmatic access to Tape D is sold on the Premium tier and distributed exclusively through Nasdaq Data Link; NPM itself publishes no developer portal, API reference, or machine-readable specification.
