Polymarket Ventures into Private Company Valuations with New Prediction Markets
Polymarket, a prominent prediction market platform, is venturing into the highly exclusive realm of private company valuations. In May 2026, the company launched contracts tied to the milestones of “unicorn” companies—privately held startups valued at over $1 billion. These new offerings encompass approximately 1,600 private companies with a collective valuation exceeding $5 trillion.
New Contracts Target Unicorn Milestones
The newly introduced contracts allow users to speculate on various outcomes for some of the world’s most significant privately held firms. These include the timing of initial public offerings (IPOs), valuation thresholds, and activity in secondary share markets. Data for resolving these markets will be sourced exclusively from Nasdaq Private Market. Notably, these equity-linked markets are accessible only through Polymarket’s offshore platform, which is unavailable to U.S. residents.
U.S. Operations and Regulatory Scrutiny
Polymarket’s domestic operations are managed by QCX LLC, a subsidiary regulated by the Commodity Futures Trading Commission (CFTC). Polymarket acquired QCX LLC in July 2025, three years after settling with the CFTC for $1.4 million due to prior unregistered activities. The U.S. platform currently hosts prediction markets focused on public stock metrics, such as the daily direction of the S&P 500 and market capitalization rankings.
Legal Experts Raise Concerns Over Jurisdiction
Legal experts have voiced concerns that equity-tied contracts could be classified as security-based swaps. Such a classification would place them under the jurisdiction of the Securities and Exchange Commission (SEC) rather than the CFTC. Security-based swaps are subject to distinct registration requirements, disclosure obligations, and anti-fraud provisions.
New York Lawsuit Targets Gambling Operations
On September 24, 2026, New York Attorney General Letitia James and Governor Kathy Hochul initiated a lawsuit against Polymarket, alleging illegal unlicensed gambling operations. This legal action specifically targets Polymarket’s sports-related contracts.
Federal Preemption and State Enforcement
The extent to which federal preemption shields CFTC-regulated platforms from state-level gambling statutes remains an open question. Even if Polymarket’s U.S. platform, regulated by the CFTC, is protected from state gambling laws, the offshore platform offering the equity contracts operates in a different legal landscape. New York’s lawsuit could potentially establish a precedent that prediction market operators with any U.S. connection face state enforcement actions, irrespective of where specific contracts are offered.
Information Asymmetry in Private Markets
A significant challenge in private company prediction markets is the inherent asymmetry of information. Employees, investors, and board members often possess material nonpublic information that could provide them with substantial advantages in markets tied to company milestones. Unlike public equity markets, which have established regulatory frameworks to prevent insider trading and informational edge, private company prediction markets currently lack such safeguards.
Potential SEC Intervention and Regulatory Framework
Should the SEC determine that these equity-linked contracts qualify as security-based swaps, Polymarket would be compelled to adhere to a significantly different regulatory framework. This could involve registering as a security-based swap execution facility, implementing mandatory reporting, and complying with Regulation SCI for market infrastructure.
Industry Precedent and Trader Risks
Other prediction market operators, such as Kalshi, are also expanding into financial event contracts. A definitive ruling on the regulatory classification of equity-linked prediction markets would set a crucial precedent for the entire industry. For traders currently utilizing the offshore platform to speculate on unicorn milestones, the primary risk is the potential for regulatory actions to disrupt markets, necessitate contract unwinding, or alter resolution terms with little advance notice. Polymarket has previously settled with the CFTC once.
