Prediction market Polymarket adds private company bets

Polymarket, a crypto prediction market platform, has launched contracts tied to private-company milestones through a partnership with Nasdaq Private Market, which will provide the data used to settle the trades.

The new markets let users take positions on events such as valuation targets, IPO timing, and secondary share activity at private firms, without owning equity in those companies.

Private-company investing has usually been limited to venture firms, institutions, and accredited investors, while Nasdaq Private Market, which runs infrastructure for private share trades, will use its transaction and valuation data to decide whether each contract resolves to yes or no.

🧠 Food for thought

Implications, context, and why it matters.

These new markets operate under the long shadow of insider trading laws

The Department of Justice filed its first insider trading case tied to prediction markets with the Commodity Futures Trading Commission (CFTC) 1. The case involves Polymarket and a U.S. Army soldier who allegedly made more than $400,000 by using classified military information 1.
Regulators said the legal theory reaches beyond government secrets. It can also cover people who misuse confidential corporate information to trade event contracts 2.
That raises legal risk for employees, contractors, or bankers tied to private companies in these markets. Trading on non-public details about funding rounds or company performance could draw scrutiny 3.
The CFTC’s enforcement division has called the idea that insider trading is allowed in prediction markets a “myth.” That language signals close scrutiny of these products 2.

A new public price signal for historically opaque private markets

The partnership could create a two-way data flow. Nasdaq Private Market, a platform for private share transactions, could supply verified data for settlement while Polymarket trading could offer a real-time signal for institutional investors 4.
It could also add a public gauge of sentiment around private company valuations and initial public offering timing. Those prices have long been inferred from limited, infrequent transactions 4.
For founders and employees with stock options, those odds could become a new benchmark. They could serve as a counterweight to company-set valuations and secondary market trades 4.
The move also fits a broader push to bring prediction markets into mainstream finance. Intercontinental Exchange, the owner of the New York Stock Exchange, reportedly agreed to invest up to US$2 billion in Polymarket at an US$8 billion pre-money valuation in 2025 4.
