OpenAI is preparing to do something no AI company has done at this scale: let public markets, rather than venture investors, decide what ChatGPT’s parent company is actually worth.
The Numbers Driving the Filing
OpenAI is working with Goldman Sachs and Morgan Stanley, alongside Citigroup and JPMorgan, on a confidential IPO filing targeting a public debut as soon as September 2026. Reported valuation targets have climbed steadily through the year, from an initial range around $730 billion to $850 billion in June toward figures now touching $1 trillion. The company’s last disclosed private valuation, from a March 2026 funding round backed by Amazon, Nvidia, and SoftBank among others, was $852 billion.
The growth numbers behind that valuation are genuinely large: OpenAI reports roughly $2 billion in monthly revenue, more than 900 million weekly active users on ChatGPT, and enterprise contracts now driving over 40% of revenue. Full-year 2026 revenue is projected around $30 billion.
The Number Every Investor Will Actually Stare At
The catch is equally large. OpenAI is projected to lose approximately $14 billion in 2026, and the company has said it doesn’t expect positive cash flow until 2030. One widely cited estimate puts OpenAI’s total cash burn at over $100 billion by the end of the decade. That combination — a trillion-dollar valuation target sitting on top of a business that loses more than a dollar for every dollar of revenue it earns, by some estimates — is exactly the kind of gap that public market discipline is built to test in a way private funding rounds never have.
Not the Only AI Giant Headed for Wall Street
OpenAI isn’t going public alone. Rival Anthropic confidentially filed its own draft S-1 with the SEC on June 1, 2026, and is reportedly targeting an October listing that could value the company north of $900 billion — a story we cover in more detail in our coverage of Anthropic’s push toward profitability. SpaceX has separately filed its own public S-1, targeting a valuation between $1.75 trillion and $2 trillion. Having three of the most valuable private companies on Earth head toward public markets within the same several-month window is, by any measure, unprecedented, and whichever lists first will effectively set the pricing benchmark the others get measured against.
Why the Timing Makes Sense for OpenAI
The trillion-dollar AI infrastructure buildout — chips, data centers, energy contracts — has created real cash pressure across the entire industry, and that pressure is a significant part of why both OpenAI and Anthropic are turning to public capital markets now rather than waiting. Public listings unlock a fundamentally larger pool of capital than private venture rounds can provide, which matters enormously for companies whose compute costs are scaling as fast as their revenue.
What Changes for Ordinary Investors
For most of the AI boom to date, the financial upside has flowed almost entirely to venture funds and a narrow set of private investors. A successful OpenAI listing would change that, letting ordinary investors — and, by extension, the index funds inside many people’s retirement accounts — hold shares in OpenAI directly, in some cases without actively choosing to. That access cuts both ways: buying into a company valued heavily on future expectations rather than current profitability carries real risk if growth or margins disappoint once the numbers are audited and public.
What to Watch Next
The SEC-mandated disclosures that come with a public filing will be the first time outside investors get to see OpenAI’s actual audited financials — cost structure, margins, and contractual obligations that have stayed behind private-company walls until now. Watch for the final pricing and share count, which OpenAI has said depend entirely on market conditions at the time of listing, and for how the broader AI IPO wave performs once real trading begins rather than projected valuations.
