New markets will let users trade on fundraising, valuation and other startup milestones using data from Nasdaq Private Market, extending forecasting into private capital. Polymarket has launched a new category of prediction markets tied to private companies, allowing users to trade on questions related to pre-IPO companies — a move that could bring greater price discovery to private markets, where valuation data is often limited and opaque. The new offering, announced Tuesday, was developed in partnership with Nasdaq Private Market, a platform that facilitates secondary trading in shares of privately held companies. Nasdaq Private Market will provide the underlying data and market infrastructure for the contracts. The markets are designed to reflect expectations around events such as fundraising rounds, valuation changes and other corporate milestones involving startups and late-stage private companies. The launch expands Polymarket’s product lineup beyond its core markets focused on politics, macroeconomic events and public companies. The move is part of Polymarket’s effort to broaden its appeal to financially oriented users and extend prediction markets into private capital markets, where pricing information is often less accessible and less transparent than in public equities. Polymarket said the rise of so-called unicorns — privately held startups valued at $1 billion or more — has increased demand for market-based forecasting tools tied to private companies. The platform noted that there are nearly 1,600 unicorns worldwide with a combined valuation exceeding $5 trillion, despite access to these companies remaining largely limited to private investors.
