OpenAI does not follow a clean seed-to-Series-D public dataset, so the useful analysis is late-stage valuation resets and Segmara's current indicative mark.

Analytical lens
Search intent
Searches like 'OpenAI Private-Market Access' are research questions: what a filing or a company statement confirms, what has only been reported, and what is still unknown.
What counts as a listing step
For an IPO, the primary record is a registration statement filed with the securities regulator of the listing market, such as an S-1 or F-1 on SEC EDGAR for a US listing. Funding rounds, valuations and secondary-market prices are context, not listing steps.
Segmara role
Segmara is an independent research site. It does not sell, broker, or arrange share purchases, and nothing on this page is investment advice.
How a company reaches a US listing
The SEC filing trail
DraftThe company can first submit a draft registration statement (DRS) for confidential SEC review.
S-1 or F-1The registration statement goes public on SEC EDGAR: Form S-1, or Form F-1 for many foreign companies. A company that used a draft must file publicly at least 15 days before its roadshow.
AmendmentsS-1/A or F-1/A amendments answer SEC comments, and one of them adds the expected price range.
PricingOnce the SEC declares the registration effective, the company sets the price with its underwriters and files the final prospectus, usually a 424B4.
First tradeThe shares start trading on the exchange named in the prospectus, such as Nasdaq or the NYSE.
Sources: SEC, March 3, 2025 · Investor.gov, October 14, 2022 · Regulation S-K Item 501 · SEC Form F-1.
