The company had announced confidential preliminary SEC paperwork in June, but said it had not decided when to list. Its extraordinary private valuations and reported revenue run rate explain the IPO speculation; they do not establish an IPO date, offer price or ranking as the year’s most lucrative listing.
What OpenAI has—and has not—said about going public
In June 2026, OpenAI said it had submitted confidential preliminary SEC paperwork. That step can give a company the option to move toward a public offering, but it is not a scheduled IPO, a public prospectus or a guarantee that the company will list. OpenAI said it had not decided on timing and described going public as a tradeoff: some things may be easier to do as a private company, while filing preserves the option to go public sooner if that proves best. The statement, reported by the Associated Press, said: “We have not decided on timing yet; it may be a while because there are things we want to do that are likely easier as a private company. But it’s a complicated set of tradeoffs and this gives us the option to go public sooner if that ends up being best.”
In September, reporting on Altman’s comments to Fortune said OpenAI would not go public in 2026. That makes a 2026 listing an unsupported premise, not a settled event. The company’s future plans could change, but the available reporting does not establish a later IPO date either.
Why OpenAI’s private-market valuation fuels IPO speculation
Private financing figures have made an eventual public offering seem plausible, but they describe investment in a private company—not what an IPO would raise or what public investors would pay for its shares.

| Figure | What it describes | Qualification |
|---|---|---|
| $122 billion | Capital committed in an OpenAI financing round | Bloomberg reported the completed round in March 2026. |
| $852 billion | OpenAI’s valuation after that round | Bloomberg’s March 2026 figure is a private-market valuation, not an IPO offer price or public market capitalization. |
| At least $30 billion | Funding sought in a proposed further round | Reuters reported in September 2026 that discussions were at an early stage and terms could change; this was not completed funding. |
| About $1.4 trillion | Target valuation discussed for that proposed round | Reuters reported this as a potential private-round valuation, not a final valuation or an IPO price. |
Valuation and proceeds answer different questions. A valuation estimates the worth assigned to the company or its shares at a particular transaction; proceeds are the cash raised by selling shares. A public offering’s terms would determine how many shares are sold, at what price and how much money the company and any selling shareholders receive. None of those IPO details can be inferred from a proposed private-round valuation.
What the revenue figures do—and do not—show
Axios reported on October 8, 2026, that OpenAI’s annualized revenue was about $50 billion. Annualized revenue projects a shorter-period result forward; it is not the same as audited revenue for a completed fiscal year. The label matters when comparing companies or using a headline figure to estimate future public-market value.

Axios also explained that a previously circulated $70 billion OpenAI figure grossed up partner sales to make a comparison with Anthropic more comparable. That accounting presentation is not interchangeable with the roughly $50 billion figure. Treating both as the same measure—or as audited full-year sales—would overstate what the reported figures establish.
Why an OpenAI–Anthropic comparison needs care
In August 2026, Axios reported an annualized revenue run rate of more than $65 billion for Anthropic and $40 billion for OpenAI, while cautioning that the measurements might differ. The October reporting subsequently clarified the gross-up behind the higher $70 billion OpenAI figure that had circulated. These are dated run-rate estimates, not a clean comparison of audited results over the same reporting period.

Partner-sales treatment can change a reported comparison: one company’s figures may count partner-related sales differently from another’s. Without matching the reporting date, time period and gross-versus-net treatment, the figures cannot establish which company has higher comparable revenue, much less determine what either company’s shares would be worth in a public offering.
What “most lucrative IPO” would have to mean
“Most lucrative” has no single financial definition. It could refer to the amount raised in the offering, the company’s valuation at the offer or listing, or the returns investors earn after trading begins. Those measures can produce different rankings, and each requires a defined comparison with other IPOs in the same year.

A private funding valuation cannot substitute for any of these measures. The reporting cited here does not provide a scheduled OpenAI listing or a complete 2026 IPO ranking that would support the superlative.

A confidential filing and media-reported financing discussions are not enough to assess an offering. Investors would need public documents and terms that establish what is actually being sold and on what basis.

Until those details exist, the defensible conclusion is narrower: OpenAI has attracted unusually large private financing and valuation figures, but those figures do not make a 2026 IPO—or a record-setting one—a fact.
