A majority, stated as a word

In its March 31, 2026 funding announcement, OpenAI reported that enterprise made up more than 40% of its revenue and projected that it would reach parity with consumer revenue by the end of 2026. The company also reported $2 billion in monthly revenue. These were company-provided figures, not independently audited measurements in the announcement.

Seven months later, the update arrived without numbers. At a Wall Street Journal tech conference in Napa on November 4, president Greg Brockman said enterprise sales now generate the majority of OpenAI's revenue, according to Reuters. If Brockman's description reflects the same revenue categories OpenAI used in March, it suggests the company has passed its own parity target roughly two months ahead of schedule. The March announcement presented enterprise as a rapidly growing business inside a predominantly consumer-facing company. That balance may now have shifted. The March announcement led with the consumer machine: more than 900 million weekly ChatGPT users, over 50 million subscribers, six times the web and mobile sessions of the next largest AI app. Enterprise was the growth story inside a consumer company. By Brockman's account, enterprise sales now represent the larger share of the business. OpenAI has not disclosed the percentage or explained how it defines that category.

How much larger, he did not say. A majority can mean 51% or 80%, and at OpenAI's scale the difference between those two readings is larger than most AI companies' entire revenue. No updated monthly total was offered either, so there is no way to convert the word into dollars from anything said on that stage.

The bucket has no published edges

There is a second gap, and it predates Napa. OpenAI's March announcement did not define what counts as enterprise revenue. The announcement discusses enterprise revenue alongside API usage and Codex adoption, but does not explain which product lines or customer categories are included in the enterprise figure. Reuters adds that the business push includes selling Codex into companies against Anthropic, which is consistent with that passage, but it does not settle the definition.

That matters because the comparison readers will reach for is Anthropic. Both companies sell to businesses and individual users, but the available figures do not establish a like-for-like revenue comparison. Without a shared definition of enterprise revenue and an actual percentage, Brockman's statement cannot tell us whether OpenAI's business mix resembles Anthropic's, or how the two companies compare in enterprise revenue dollars.

"I think so" is a readiness answer, not a timetable

The IPO half of the wire is three words. Asked on stage whether OpenAI will be ready for an initial public offering next year, Brockman said: "I think so."

Read the question before the answer. He was asked about readiness, not about filing, pricing or listing, and he committed to none of them. Reuters placed the answer against two pieces of its own context: OpenAI has delayed its IPO plans while racing to ramp up fundraising to capitalize on its recent growth, and Anthropic is likely to go public before the end of this year. ALFW reported the fundraising side of that sequence on October 19, when OpenAI was accelerating a roughly $30 billion round ahead of Anthropic's expected disclosures. These developments provide financial and strategic context, not evidence that Brockman's answer represents a formal change in IPO plans. Brockman's answer is a statement of confidence, not a commitment. OpenAI can consider itself operationally ready for an IPO in 2027 without having decided to file, set a listing date or committed to going public. Reuters' reporting about delayed IPO plans and ongoing fundraising provides context, but neither establishes a revised timetable.

What would make it more than that is paperwork: a public filing, audited financials, a date. None was mentioned in Napa.

What would settle both claims

Both halves of this story need further disclosure. The revenue mix needs a percentage and a definition; the IPO question needs something more concrete than an executive's assessment of readiness. One percentage would convert "majority" into a measurement and show whether the parity target was beaten narrowly or by a wide margin. One updated revenue total would show whether the mix shifted because enterprise grew, because consumer growth slowed, or both. An eventual IPO filing could provide audited financial statements and more information about OpenAI's business. Whether it discloses the same consumer-versus-enterprise breakdown, however, remains unknown.

Until then, the accurate summary is narrow. The president of OpenAI says the business side of the company is now the bigger side, ahead of the schedule the company set itself in March. He gave the direction and withheld the size.
