OpenAI knocks on the stock market door

The world's most talked-about AI company has taken its first formal step toward a public listing. According to Yahoo Finance, OpenAI submitted a confidential S-1 document to the U.S. Securities and Exchange Commission (SEC) on June 8, 2026, firing the starting gun on what could become one of the most spectacular technology IPOs ever seen.

Confidential filings are a common legal mechanism that allows companies to navigate the SEC process without full public exposure in the early stages. The market will not normally see the details of the S-1 prospectus until the company chooses to go public.

Astronomical valuation – but deep in the red

In March 2026, OpenAI was valued at $852 billion in a private funding round. Analysts have since speculated on far higher figures: some cite $1 trillion as a realistic floor, while the most optimistic estimates stretch to $2.5 trillion at the time of listing.

The growth story driving these numbers is impressive: the company reports over 900 million weekly ChatGPT users and monthly revenue of $2 billion.

Yet the numbers only tell half the story. According to research obtained by 24markets, OpenAI is expected to post a $14 billion loss in 2026, and the company itself does not anticipate reaching profitability until 2029 or 2030 at the earliest. Prospective public investors will need to price in a very long road to profitable operations.

Market share under pressure

A further complication is the trajectory of the API market. OpenAI's share of the enterprise API market fell from 50 percent in 2023 to between 25 and 34 percent during 2025 and early 2026 – and forecasts suggest it could drop below 20 percent by 2027. Competitors including Anthropic, Google, and a range of open-source models are steadily gaining ground.

Nick Patience, analyst at Futurum Group, notes that investors should pay close attention to how OpenAI allocates its IPO capital: "Agentic AI is coming, and is already here to some extent. How they use the capital to invest in that will be critical," he stated in connection with the listing plans.

Public investors will demand clearer paths to profitability, operational discipline, and margin growth. That means the valuation will likely be rationalized over time.

Those are the words of Kashyap Kompella, CEO of RPA2AI Research, who notes that the public markets impose different demands than risk-tolerant venture capital.

Ripple effects across the market

A successful OpenAI IPO could have significant consequences well beyond the company's own shareholders. Analysts point out that a series of high-profile AI listings – including potential IPOs from Anthropic and SpaceX – could trigger capital rotation out of other sectors, including cryptocurrency and Web3.

At the same time, markets are speculating on positive spillover effects: heightened risk appetite around AI stocks could lift AI-related crypto tokens and decentralized AI projects such as Bittensor, SingularityNET, and Fetch.ai. The total market for AI agents within Web3 already carries a market capitalization of over $7.7 billion and daily trading volumes of nearly $1.7 billion, according to research.

A disappointing market debut, however, could dampen sentiment across the entire AI sector – including crypto-related AI projects.

What happens next?

A confidential filing is typically followed by a period of SEC feedback, then public release of the prospectus, and finally a roadshow and pricing. The timeline is not publicly known, but the market will follow every update closely.

With the crypto Fear & Greed Index sitting at 9 out of 100 and broad risk aversion across markets, the timing of any potential listing will be critical. Aravind Srinivas, CEO of rival Perplexity, has stated that "it's important for the AI industry that these IPOs go well – and I truly believe they will go well, because the companies are doing well."

If he is right, OpenAI's market debut could mark a watershed moment for the entire technology sector in 2026.
