OpenAI's IPO, Explained: What's Confirmed and What's Still Guesswork

What's Actually Confirmed

OpenAI confidentially filed a draft registration statement with the SEC on May 22, 2026, formally beginning the process of going public. Goldman Sachs and Morgan Stanley are reported to be leading the deal, later joined by Citigroup and JPMorgan Chase as additional underwriters. Multiple outlets, citing people familiar with the matter, say the company is targeting a public debut as soon as the fourth quarter of 2026 — though the exact timing, size, and valuation of the offering have not been disclosed, and some reporting from June 2026 suggested internal discussions about pushing the listing into 2027 instead.

What OpenAI has stated publicly: the company is generating roughly $2 billion in revenue per month, growing faster at this stage than Alphabet or Meta did, with enterprise revenue now making up more than 40% of the total and expected to reach parity with consumer revenue by the end of 2026. CFO Sarah Friar has also confirmed the company is not yet profitable, and has reportedly pushed internally for a later IPO timeline given the scale of OpenAI's spending commitments and the reporting obligations that come with being a public company.

Growth, Losses, and the Trillion-Dollar Question

OpenAI's revenue is growing fast, but so are its losses, which is the central tension in every valuation estimate.

OpenAI's revenue trajectory is genuinely unusual: from roughly $2 billion annualized at the end of 2023, to $6 billion in 2024, to more than $20 billion by the end of 2025, according to figures its CFO has confirmed. The 2026 target is around $30 billion. But scale hasn't brought profitability closer — the company is projecting a loss of roughly $14 billion this year alone, and some analyst estimates put cumulative losses as high as $115 billion by 2029, with profitability not expected until sometime in the 2030s.

That gap is funding an enormous infrastructure buildout: OpenAI has committed to more than $1.4 trillion in data-center and compute spending over the coming years, according to CEO Sam Altman's own public statements. One analyst estimate from HSBC suggests the company could need over $207 billion in additional funding by 2030 just to keep pace with that commitment, even accounting for continued revenue growth — a funding gap that helps explain why going public, with access to public capital markets, has become increasingly attractive.

On valuation: OpenAI's March 2026 private funding round valued the company at roughly $852 billion. Multiple reports since then have floated an IPO valuation target as high as $1 trillion, which would make it one of the largest public listings ever. It's worth being clear that these are estimates from unnamed sources and analyst projections, not a number OpenAI has confirmed — the company has not disclosed pricing, share structure, or valuation for the actual offering.

How We Got Here

Why This Matters Beyond OpenAI

OpenAI isn't racing alone. Anthropic has also confidentially submitted draft paperwork for a public listing, and the two companies are widely described as racing each other toward a Wall Street debut. That competitive dynamic partly explains the urgency: whichever company lists first will likely set the benchmark valuation and investor expectations that the other has to match or beat.

There's also a structural story underneath the headline numbers. Google's Gemini has grown its share of AI web traffic sharply over the past year while ChatGPT's share has declined, according to Similarweb data cited by market analysts — a reminder that OpenAI's IPO pitch has to convince investors not just that the company is big, but that its lead is durable in a market where competitors are closing the gap fast.

What Happens Next

Until OpenAI publicly files its S-1 (rather than the confidential version already submitted), the size, structure, and pricing of the offering remain genuinely unknown. Confidential filings let a company work through SEC review privately before committing to a public timeline, so a Q4 2026 debut is plausible but not locked in — and reporting throughout 2026 has shown real disagreement inside the company about whether to wait until 2027.

For anyone following this closely: watch for the public S-1 filing, which typically comes shortly before a listing and includes real financial statements and share pricing details, rather than relying on leaked valuation figures or anonymous-source reporting in the meantime.
