OpenAI Stock FAQ

No. OpenAI is a private company and does not trade on any public stock exchange. Its most recently reported valuation was set in its Series G round (February 2026, source: Sacra).

OpenAI does not have a public stock price because it is privately held. The most recent known share price comes from its last funding round. Growth, 02/27/26, Sacra Pre-IPO share prices on the secondary market may differ from the last round price depending on supply, demand, and market conditions.

No. OpenAI does not allow direct share transfers or fund investments at this time, so UpMarket does not offer access to OpenAI shares. Accredited investors can register with UpMarket to see the private market opportunities that are currently available.

Pre-IPO investments carry significant risks. Shares are illiquid, meaning there is no public market to sell them quickly. There is no guaranteed exit timeline or return. These investments are speculative, and investors should be prepared for the possibility of total loss. Valuations of private companies can fluctuate substantially between funding rounds. Investors should consult their financial advisor and review all offering documents before investing.

In a pre-IPO transaction, accredited investors purchase shares from existing shareholders (such as employees, early investors, or other holders) through secondary market platforms. The company itself does not issue new shares in these transactions. UpMarket facilitates these trades as a FINRA-registered broker-dealer, handling compliance, documentation, and settlement on behalf of both parties.

There are two primary exit paths for pre-IPO holdings: selling shares on the secondary market to another buyer, or holding until the company completes an IPO or is acquired. Both paths are subject to transfer restrictions, company approval (right of first refusal), and market conditions. The timing of any exit is unpredictable, and investors should plan for a multi-year holding period.

The minimum investment for most pre-IPO offerings on UpMarket is $50,000. This amount may vary depending on the specific offering and share availability. There are no fees to create an UpMarket account or browse available investments. OpenAI is not currently available on the platform.

UpMarket's valuation estimate of $730B is derived from a proprietary model that incorporates multiple data sources: funding round data (Caplight), revenue estimates (Sacra), secondary market pricing, and public company comparables. The model applies a private company discount to the public comp multiple to account for illiquidity and information asymmetry. This estimate is not investment advice and may differ substantially from the price at which shares actually trade.

OpenAI reached a $730B valuation in its 2025 funding round and operates ChatGPT — the world's most widely used AI application — with annualized revenue exceeding $10B and secondary market shares available now — accredited investors can access OpenAI stock through UpMarket.
