OpenAI Enterprise Sales Now the Majority of Revenue as Brockman Signals 2027 IPO Readiness

OpenAI president and co-founder Greg Brockman said enterprise sales now generate the majority of the company's revenue, according to a Reuters report published on November 5. He made the remark on November 4 at a conference in Napa, California, in a session titled OpenAI's Race to Scale, moderated by Wall Street Journal reporter Keach Hagey.

Asked in the same session whether OpenAI would be ready for an initial public offering in 2027, Brockman answered that he thinks so. The reply came with no timetable, no underwriting arrangements and no valuation guidance, but against a backdrop of delayed listing plans and accelerated fundraising it stands as the clearest IPO signal the company has given.

The contrast with OpenAI's March 31 funding announcement is stark. At the time the company said enterprise accounted for more than 40 percent of revenue and was on track to reach parity with consumer revenue by the end of 2026, with the business generating about $2 billion a month. Enterprise has shifted from a business chasing the consumer side to the larger contributor.

The consumer base remains the foundation underneath that. The March announcement reported more than 900 million weekly active ChatGPT users and over 50 million subscribers, framing everyday familiarity with ChatGPT as the route into workplace adoption.

At the product level, Codex is the visible instrument of the enterprise push. OpenAI said the coding agent's weekly user base passed 2 million after growing fivefold in three months, with activity up more than 70 percent month over month. Brockman placed Codex at the centre of his account of competition for business customers.

The other half of the IPO question is money and compute. The March announcement described a round with $122 billion in committed capital at an $852 billion post-money valuation, anchored by Amazon, NVIDIA and SoftBank with continued participation from Microsoft, plus a revolving credit facility expanded to roughly $4.7 billion that remained undrawn at close.

The competitive calendar is pushing the issue too. Reuters reported that Anthropic is likely to go public before the end of 2026, which forms the reference point for Brockman's answer. For enterprise buyers, the head-to-head contest in coding and office work will not end with whichever company lists first.

One caveat matters: the majority-of-revenue claim is Brockman's verbal characterization, not a published financial disclosure, and OpenAI has not broken out enterprise versus consumer revenue. What to watch next is whether a future funding round or listing document supplies that split, and whether Codex can convert user growth into durable contracted revenue.
