Indicative listing context
Thinking Machines Lab Stock Price (Pre-IPO)
Ask for the Thinking Machines Lab stock price and the honest answer is that none exists officially, since the AI research lab co-founded by former OpenAI CTO Mira Murati remains private and unlisted. Secondary-market trackers do not agree on an exact mark: Forge Global quoted $318.92 per share as of August 29, 2026, while notice.co showed $276.60 the same day, against a $12 billion post-money valuation from the company's Series Seed round in July 2025. Segmara maintains an indicative pre-IPO reference mark for Thinking Machines Lab in the data summary below, built from those private-market signals. A free email tracker lets you follow the mark before any listing happens.

Analytical lens
Search intent
Searches like 'Thinking Machines Lab Stock Price (Pre-IPO)' 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.
