Polymarket Opens Private Company Bets to Retail Traders

Polymarket, the world’s largest cryptocurrency-based prediction market platform, launched a groundbreaking expansion on Tuesday that allows retail traders to speculate on the valuations, IPO timing, and secondary market activity of major private companies. Through a new partnership with Nasdaq Private Market, the platform is opening a $5 trillion private market segment that has historically been accessible only to institutional investors and high-net-worth individuals.

A New Frontier for Prediction Markets

The expansion marks a significant shift for prediction markets, which have traditionally focused on event-based wagering in categories such as politics, sports, and entertainment. Now, users can trade event contracts tied to the financial performance of some of the world’s most valuable private companies, including OpenAI, Anthropic, SpaceX, Stripe, Databricks, Kraken, Neuralink, and Anduril.

“For the first time, anyone can engage with the outcomes driving value at the world’s most consequential private companies,” Shayne Coplan, founder and CEO of Polymarket, said in a statement.

These are not equity investments — users gain no shares, voting rights, or dividends. Instead, they buy and sell binary event contracts that pay out based on whether specific milestones are met, such as a company reaching a certain valuation by a set date or announcing an IPO before a deadline.

How It Works

Nasdaq Private Market (NPM) will serve as the exclusive resolution data provider for the new markets, supplying the information that determines whether contracts pay out. NPM publishes daily valuation estimates in the early afternoon, and for the first time, this data will be made publicly available for free — previously it required a subscription.

Rodolfo Sanchez, vice president of data at Nasdaq Private Market, said the trades will provide a “real-time signal” for investors to gauge private-market performance.

Tom Callahan of NPM added in a statement: “Polymarket has built the platform that can open access to a broader audience. We are proud to provide the data that ensures every market resolves accurately.”

Early Markets and Examples

Initial contracts available on the platform include:

  • OpenAI: A market on whether the AI giant will have a $1 trillion-plus IPO before 2027
  • Anthropic: Contracts on whether Anthropic reaches a $500 billion valuation in 2026, and whether it will be valued higher than OpenAI at any point this year
  • SpaceX: Traders are pricing in roughly 90% odds that SpaceX by June 30 will be worth between $1.5 trillion and $1.75 trillion, in line with its reported IPO valuation

According to The Block, early offerings focus on AI, fintech, and crypto unicorns. NPM’s own data shows the scale of interest: its Anthropic company page lists an estimated NPM price of $477.02 per share as of May 5, up more than 1,500%, with a last trade of $234.00.

Democratization or Gambling?

Polymarket frames this expansion as “democratizing access” to private markets — a sector where over 1,600 unicorns (companies valued at $1 billion or more) exist globally, yet ordinary investors are typically sidelined. However, critics note that these are event contracts, not equity ownership, and the distinction between investing and gambling is central to ongoing regulatory battles.

The platform has faced significant regulatory scrutiny throughout its history. In 2022, the CFTC fined Polymarket $1.4 million for operating an unregistered derivatives platform, leading to a three-year ban on U.S. customers. After a tumultuous period that included an FBI raid on Coplan’s home in November 2024, the regulatory environment shifted under the Trump administration. The DOJ and CFTC formally ended investigations in July 2025, and Polymarket acquired CFTC-licensed QCEX for $112 million. By November 2025, the CFTC issued an Amended Order of Designation allowing U.S. re-entry.

The Competitive Landscape

Polymarket is not alone in targeting private company speculation. Rival Kalshi, a CFTC-regulated platform, offers IPO event contracts but resolves them through an amalgamation of public sources and does not offer valuation markets. Earlier in May 2026, the Hyperliquid-based TradeXYZ platform launched pre-IPO perpetual futures for companies like Cerebras and SpaceX.

However, Polymarket’s scale is formidable. The platform has recorded nearly $39 billion in volume in the United States so far in 2026, according to The Block. Valued at $9 billion as of February 2026, Polymarket has attracted major backers including Intercontinental Exchange (NYSE parent), which invested $2 billion in October 2025, and boasts advisors such as former CFTC chair J. Christopher Giancarlo, Donald Trump Jr., and Nate Silver.

Implications and Risks

The expansion could have far-reaching implications for financial markets. If prediction market signals gain credibility, they could influence IPO pricing and provide institutional investors with a new real-time data point for private company valuations. However, significant risks remain:

  • Insider trading: Private company employees may possess material non-public information about valuations and IPO plans. Polymarket has already faced controversies over suspiciously timed bets on military operations.
  • Market manipulation: Thin liquidity in early markets could make them susceptible to manipulation.
  • Regulatory challenges: The platform faces state-level challenges in Nevada and Massachusetts over gambling classification, and the CFTC’s position on these new markets remains to be seen.
  • User outcomes: According to research, 0.1% of Polymarket accounts net 67% of profits, while over 70% of users lose money.

What’s Next

As Polymarket pushes into corporate finance territory, the key questions revolve around regulatory response, market liquidity, and whether these prediction markets can achieve sufficient trading volume to serve as meaningful price discovery tools. The partnership with Nasdaq Private Market provides a credible data foundation, but the ultimate test will be whether retail traders embrace these markets at scale — and whether regulators allow them to continue.

For now, Polymarket has opened a door that was previously locked to ordinary investors. Whether that door leads to democratized finance or simply a new form of speculation remains an open question.
