OpenAI Is Going Public at a $1 Trillion Valuation — And 5 Numbers Tell You Everything You Need to Know
I've been following the tech IPO market for years, and I've never seen anything like this. OpenAI has confidentially filed for a public offering with Goldman Sachs and Morgan Stanley as lead underwriters, targeting a debut as early as September 2026 — and the numbers attached to this deal are so big they almost don't feel real. We're talking about a company that could become the largest IPO in the history of financial markets. Let me walk you through the 5 numbers that explain exactly what's happening and why it matters.
Number 1: $852 Billion — The Current Private Valuation
OpenAI's last private funding round, a $122 billion raise completed in March 2026, valued the company at $852 billion. The backers in that round include Amazon, Nvidia, and SoftBank — not exactly a group known for throwing money at bad bets. For context, that valuation makes OpenAI worth more than JPMorgan Chase, more than Walmart, and more than every major US airline combined. This isn't a startup anymore. This is one of the most valuable companies on Earth, and it's still private.
Number 2: $1 Trillion — The IPO Target
Goldman Sachs and Morgan Stanley are reportedly targeting a $1 trillion valuation at IPO. If they hit that number — and that's a genuine "if" — OpenAI would become the first non-oil, non-platform tech company to go public at that valuation. Apple hit $1 trillion in 2018 after 42 years as a public company. OpenAI wants to start there. The audacity of this is breathtaking. The question is whether public market investors will pay for it.
Number 3: $25 Billion — Annualized Revenue as of February 2026
OpenAI's annualized revenue hit $25 billion in February 2026, up from $20 billion at the end of 2025. That's a 25% growth rate in two months. Sam Altman has publicly targeted $100 billion in annual revenue by 2027. If they hit even half that target, the $1 trillion valuation starts to look less crazy — that would be roughly a 20x revenue multiple, which is aggressive but not insane for a company with this growth trajectory.
But here's what the bulls aren't talking about loudly: OpenAI is reportedly still not profitable. With massive compute costs, aggressive hiring, and infrastructure deals worth billions, the path to sustainable profits is genuinely complicated. Public market investors are going to demand answers that private investors never pushed on.
Number 4: September 2026 — The Target Date
The confidential SEC filing was submitted on May 22, 2026. A September debut is tight but achievable if everything goes smoothly. The window between September and November is historically strong for IPOs — markets are typically liquid, institutional investors are back from summer, and there's a strong push to get deals done before year-end uncertainty.
The risk is market conditions. If tech stocks have a rough summer, Goldman and Morgan Stanley will almost certainly advise OpenAI to wait. A $1 trillion IPO in a down market could be catastrophic. They'll only pull this trigger when conditions are perfect.
Number 5: $100 Billion — Sam Altman's 2027 Revenue Target
Sam Altman has staked his credibility on hitting $100 billion in revenue by 2027. That's 4x growth in roughly 18 months from today. To get there, ChatGPT would need to monetize its 1 billion monthly active users far more aggressively, enterprise contracts would need to scale dramatically, and the API business would need to keep growing even as competitors like Anthropic, Google, and Meta close the capability gap.
It's not impossible. But public market investors will price in risk that private investors largely ignored. OpenAI going public isn't just a financial event — it's the moment the company has to start being fully transparent about whether the AI revenue story is real or inflated. The S-1, when published, is going to be the most scrutinized document in tech history.
What This Means for the Rest of the AI Industry
The OpenAI IPO is going to reshape the entire AI sector. If it prices well, it validates the trillion-dollar AI thesis and sends a wave of capital into every AI company trying to go public. If it stumbles, it could cool the entire sector's valuations. Anthropic, which just filed its own IPO paperwork at a $965 billion valuation, is watching this very carefully.
This is the most anticipated IPO I've ever tracked. Whether it delivers or disappoints, it's going to define how the next decade of AI investment plays out.
