OpenAI Files Confidentially for IPO: Can You Buy the Stock?

OpenAI, the maker of ChatGPT, has confidentially filed paperwork for a U.S. IPO — a step toward what could become one of the largest stock market debuts in history. The company announced the move on June 8, 2026, days after rival Anthropic filed and as SpaceX runs its own IPO roadshow, setting up a once-in-a-generation cluster of AI listings. With OpenAI last valued around $852 billion and some analysts expecting a public valuation above $1 trillion, the obvious question for most people is simple: can you actually buy the stock? Here’s the full picture.

What exactly did OpenAI announce?

OpenAI confirmed it submitted a confidential draft S-1 registration statement to the U.S. Securities and Exchange Commission. Unusually, the company announced it itself in a blog post, writing: “We recently submitted a confidential S-1. We expect it to leak so we’re just announcing it.” It added that it hasn’t decided on timing, that going public “may be a while,” but that the filing gives it the option to list sooner if that proves best.

A confidential filing is a common move for large, late-stage companies. It lets a business begin the IPO process privately — sharing detailed financials with regulators — without immediately exposing its revenue, margins, and risk factors to the public and competitors. The full prospectus becomes public later, ahead of the actual listing. OpenAI is working with Goldman Sachs and Morgan Stanley (and reportedly JPMorgan) as underwriters.

When could OpenAI go public?

Reports point to a potential listing window of September to November 2026, with September cited as the earliest possible target — but nothing is locked in. OpenAI itself stressed that timing is undecided and could be pushed back, since some things the company wants to do are easier as a private firm.

The timing is also competitive. OpenAI’s filing came roughly a week after Anthropic filed confidentially on June 1 at a reported $965 billion valuation, and both are following SpaceX, which has begun an IPO roadshow at a valuation near $1.75 trillion. We’ve been tracking this entire wave in our coverage of the SpaceX, OpenAI, and Anthropic IPO race. Bloomberg estimates the combined AI-related IPO pipeline is now worth around $3.6 trillion — a concentration of blockbuster offerings markets haven’t seen since the dot-com era. Depending on how SpaceX’s debut is received, OpenAI and Anthropic could end up racing to beat each other to market.

Can you buy OpenAI stock right now?

No — not yet. This is the key point for everyday investors. OpenAI shares are not available on any public exchange, and a confidential filing does not mean the stock is on sale. Shares only become buyable after the IPO is formally priced and listed, which hasn’t happened and may be months away.

Be especially cautious of anything claiming to offer “OpenAI shares” before then. Some crypto platforms have launched derivative products designed to track OpenAI’s estimated valuation, but those are synthetic instruments — not actual equity in the company — and carry their own significant risks. Until OpenAI lists, the only direct exposure is indirect: Microsoft, OpenAI’s largest strategic investor, whose own stock moves partly on OpenAI’s fortunes (and which is pushing its own AI agenda, as we covered at Build 2026). None of this is financial advice — it’s simply where things stand today.

How much money is OpenAI actually making — and losing?

This is where the IPO gets interesting, because going public will force OpenAI to disclose hard financials for the first time. Here’s what’s known: OpenAI said in March 2026 it was generating roughly $2 billion in monthly revenue, an enormous figure driven by ChatGPT subscriptions, API usage, and enterprise deals — the kind of commercialization push reflected in its $4 billion deployment company and products like GPT-5.4.

But revenue isn’t profit. According to one analysis of its financials, OpenAI lost roughly $1.22 for every dollar it earned in a recent quarter — the cost of training frontier models and running massive compute is staggering. Skeptics have been blunt: one prominent investor reportedly called the implied valuation multiple “priced for a monopoly outcome that does not yet exist,” and analysts at HSBC estimate OpenAI may need over $200 billion in additional capital by 2030 even under optimistic projections. The eye-watering compute bills behind these numbers are the same forces powering Nvidia’s record earnings. They also help explain cost cuts like the Sora shutdown, where OpenAI narrowed access to an expensive video product while keeping its broader AI infrastructure push intact.

Why is OpenAI going public now?

Two reasons. First, capital. The AI arms race is extraordinarily expensive, and public markets are far deeper than private ones. As OpenAI’s CFO Sarah Friar put it, tapping public markets makes sense for a company of OpenAI’s scale, and the company has been operating with “the good hygiene of a public company” — measuring revenue as if it already reported to the SEC. A listing at current valuations would make OpenAI one of the 15 biggest companies in the S&P 500.

Second, competition and timing. With Anthropic and SpaceX moving, OpenAI doesn’t want to be left behind in the race for investor capital — and a relatively hands-off SEC under the current administration makes the environment friendlier for tech listings. The rivalry with Anthropic in particular keeps intensifying, the same dynamic we cover in our Claude vs ChatGPT vs Gemini comparison, and it now extends to the public markets, where investors will soon be able to compare two direct competitors using real numbers.

What should you watch for next?

A few things will determine how this plays out. The public S-1, when it’s released, will reveal OpenAI’s true revenue, losses, and risk factors — the first real test of whether the company’s valuation is justified. SpaceX’s reception will set the tone for the whole AI IPO window. And the risk disclosures matter: OpenAI faces mounting legal and safety scrutiny, including cases like Florida’s lawsuit against the company, plus stiffening competition from Anthropic, Google, and cost-efficient challengers like DeepSeek.

For ChatGPT users, the practical impact is minimal in the near term — the product won’t change overnight. But a public OpenAI will face quarterly pressure to show profitability, which over time could influence pricing, free-tier limits, and how aggressively it monetizes. For now, the filing is a milestone, not a finish line.
