The companies said nearly 1,600 unicorns globally now hold more than $5 trillion in cumulative value.While traders will not own equity in the companies themselves, they can take positions on outcomes tied to firms that have largely remained inaccessible to everyday investors.Private-company investing has traditionally been reserved for venture capital firms, institutions and wealthy accredited investors. Even as startups like OpenAI, SpaceX and Stripe reached valuations larger than many public companies, most retail investors had little way to participate in the growth happening before an IPO.Polymarket’s new offering attempts to bridge that gap by turning private-market developments into tradable prediction contracts.Nasdaq Private Market will act as the official data provider for the contracts. The firm operates secondary market infrastructure for private-company shares and tracks transaction and valuation data across private markets. That data will determine whether markets resolve to “yes” or “no.”The companies also framed the product as a new form of price discovery for institutional investors. Because private markets lack the transparency of public equities, pricing information often emerges slowly through funding rounds or secondary sales. Prediction markets could offer a real-time signal of how traders view the trajectory of major startups.12345678910
