OpenAI Files Confidentially for a Stock Market Listing
OpenAI has confirmed it filed a confidential S-1 with the US securities regulator, joining the race to go public alongside Anthropic and SpaceX.
- On June 8, 2026, OpenAI confirmed it had confidentially filed an S-1 with the US Securities and Exchange Commission (SEC).
- The company's latest valuation stands at 852 billion dollars, and some analysts expect the figure could pass one trillion.
- Rival Anthropic filed the same paperwork a week earlier, on June 1, at a valuation of roughly 965 billion to one trillion dollars.
- Elon Musk's SpaceX plans to go public on June 13, at an estimated 1.8 trillion dollars.
Is OpenAI going public? Yes, but on its own terms: the company behind ChatGPT confirmed on June 8 that it has filed the paperwork, while making clear it is in no hurry to say when the debut will actually happen. The document in question is an S-1, the first formal step toward a stock market listing, submitted to the US securities regulator.
A confidential filing means the company starts the process but keeps the details, the numbers and the financial statements out of public view for now. It is a routine move for large tech firms. It gives them room to prepare, to talk to regulators and to pick a timeline without the pressure of a market that already knows everything.
What exactly did OpenAI file, and what is it worth?
The key document is the S-1, the form companies submit to the SEC before any public share offering. In a blog post, OpenAI said the filing was confidential and that no decision on timing had been made yet.
The message from the company itself was calm and deliberately unhurried:
We have not decided on a timeline, and it may take a while because there are things we want to do that are easier while we are a private company.
In other words, the papers are in, but OpenAI is not rushing. That makes sense given the scale of the numbers. Its latest valuation, set in a March 2026 funding round, stands at 852 billion dollars. Some analysts believe the firm could cross the one trillion dollar mark once it lists, which would place it among the most valuable companies in the world.
For context, these are figures you would not have seen even from the biggest tech giants in their early years. In a relatively short span, OpenAI has gone from a research lab to one of the central players in the entire industry.
Why are all the big AI firms listing at the same time?
What makes OpenAI’s move especially interesting is the timing. The company is not alone in this race.
Its main rival, Anthropic, the company behind Claude, filed its own paperwork just a week earlier, on June 1. Its valuation on secondary markets is estimated at roughly 965 billion to one trillion dollars, putting it in the same league as OpenAI. Two firms that fight daily for the same users and the same developers are now competing for the same investor money as well.
Then there is Musk’s SpaceX, which plans to go public on June 13 at an estimated 1.8 trillion dollars. SpaceX is not an AI firm, but it is part of the same story: a cluster of large private tech companies that spent years avoiding the stock market and are now opening their doors to public investors almost at once.
For the average ChatGPT user, none of this changes anything at first glance. The assistant works the same tomorrow. But going public brings something AI firms have not had to deal with before: public accountability to shareholders, quarterly reports and pressure to talk about profit, not just about how powerful the models are.
And that may be the biggest shift of all. The firm that decides today how much your assistant knows and how much it costs will, tomorrow, have to defend those same decisions to the people who put money into it. Do you think the AI tool you use will get better or worse once the company making it becomes a publicly traded one?
