Polymarket unlocks $5 trillion private market for retail traders, previously reserved for elites

Polymarket’s new private-company prediction markets let retail traders bet on startup milestones once reserved for Wall Street insiders.Updated May 19, 2026, 2:54 p.m. Published May 19, 2026, 2:51 p.m. 2 min readMake preferred on Polymarket is opening a new corner of finance to retail traders: betting on the future of private companies.The crypto-based prediction platform has introduced markets tied to private-company milestones through a partnership with Nasdaq Private Market (NPM), which will provide the data used to resolve the contracts.The new markets let users speculate on events surrounding privately held firms, including valuation targets, IPO timing and secondary share activity. 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.More For YouThe 1LwWt address received a legal notice from Salomon Brothers via Bitcoin's OP_RETURN field in July 2025 demanding the owner prove ownership by November 5, 2025.What to know: A long-dormant Bitcoin address holding 35.55 BTC since March 2011 moved its coins this week, marking one of the first visible on-chain responses from a named defendant in a sweeping New York lawsuit over 39,069 wallets.The case, brought by a pseudonymous plaintiff “Noah Doe” and two Wyoming LLCs, seeks...Read full story
