Polymarket Opens Prediction Markets on Private Companies With Nasdaq Data

Prediction market platform Polymarket has launched a new category of markets that let users trade on the future outcomes of private companies, using verified data from Nasdaq Private Market to resolve the contracts.

The offering introduces a way for traders to speculate on startup valuations, IPO timelines, and other milestones for high‑profile companies that are typically inaccessible to the public before they go public. Companies reportedly included in early markets include OpenAI, SpaceX, Anthropic, Databricks, Anduril, xAI, and Stripe.

The launch marks one of the first attempts to bring prediction‑market price signals to the opaque world of venture‑backed startups.

What the new Polymarket contracts cover

The markets focus on verifiable events involving private companies. Users buy and sell contracts that pay out depending on whether a specific outcome happens by a defined date.

Examples of the types of questions these markets can cover include:

• Whether a company reaches a specific valuation milestone
• IPO timing, such as whether a company will go public within a certain year
• Secondary market activity or liquidity events
• Other measurable business milestones or performance outcomes

Because these contracts are tied to real events rather than stock ownership, traders are effectively pricing the probability of future outcomes, which is the core mechanism behind prediction markets.

The initial markets reportedly focus on well‑known private tech and defense startups including OpenAI, SpaceX, Anthropic, Databricks, Anduril, xAI, and Stripe.

How market resolution works

A key challenge with private‑company prediction markets is verifying outcomes, since private firms do not publish the same financial data as public companies.

To solve that, Polymarket signed an exclusive agreement with Nasdaq Private Market (NPM), which provides liquidity infrastructure and transaction data for private‑company share trading.

Under the arrangement:

• Nasdaq Private Market provides the data used to settle contracts.
• NPM serves as the official resolution data provider for these prediction markets.
• Outcomes may rely on verified events such as valuation benchmarks, secondary transactions, or IPO filings.

The available reports do not describe the exact rule set for every contract, but they confirm that Nasdaq’s private‑market data will determine the final settlement of markets tied to private‑company events.

Why prediction markets for startups matter

Private markets are notoriously opaque. Startup valuations often change only during funding rounds or internal 409A valuations, leaving large gaps in publicly available information.

Prediction markets could fill that gap by producing real‑time probability signals about company outcomes.

Potential implications include:

1. Retail access to pre‑IPO speculation
Historically, only venture capitalists or accredited investors could gain exposure to private‑company growth. Prediction markets provide a way for broader participants to express views on those outcomes without owning shares.

2. Better price discovery for startups
Crowd‑based trading can generate probability signals around events such as IPO timing or valuation thresholds, potentially adding another layer of insight to private‑market expectations.

3. Institutional information signals
If markets become liquid enough, institutional investors could use them as a sentiment or expectation gauge for private‑company performance and market timing.

However, it remains uncertain whether these markets will achieve the liquidity and participation needed to produce reliable price signals comparable to public markets.

How this fits Polymarket’s broader strategy

The private‑company launch is part of a broader push by Polymarket to expand beyond its early focus on politics, crypto, and macro event forecasting.

Recent moves include:

• Expanding prediction markets into financial and corporate events
• Pursuing a regulatory comeback in the United States after a 2022 settlement with the Commodity Futures Trading Commission that restricted U.S. users.
• Acquiring QCX, a CFTC‑licensed derivatives exchange and clearinghouse, for about $112 million in 2025 to support a regulated U.S. platform.

Together, these initiatives suggest Polymarket is positioning itself as more than a betting platform. The company is attempting to build a broader “information market” infrastructure, where traders collectively price the probability of real‑world outcomes.

The bigger picture: prediction markets meet private equity

Globally, there are thousands of venture‑backed “unicorn” startups with valuations above $1 billion, representing trillions of dollars in combined value.

Yet information about those companies’ future prospects is fragmented and often delayed. By combining crowd‑driven forecasting with institutional private‑market data, the Polymarket–Nasdaq partnership aims to create a new kind of market signal for the startup economy.

Whether those signals become widely trusted will depend on participation, liquidity, and how consistently the markets resolve against verifiable data. But the experiment marks a notable step toward bringing prediction markets deeper into mainstream financial analysis.
