[UPDATE] OpenAI Files Confidentially for Its IPO

OpenAI has filed confidentially for an initial public offering, becoming the third major artificial intelligence developer to take that step in the span of a few weeks. The company submitted a draft registration to the Securities and Exchange Commission on June 8, according to CNBC and Bloomberg, which puts the broader pipeline of AI listings at roughly $3.6 trillion.

We wrote about that pipeline earlier this week. The filing turns a long-rumoured ambition into a concrete regulatory step, and it lands only days after Anthropic disclosed its own confidential filing on June 1.

What the filing says, and what it leaves open

A confidential submission lets a company start the IPO process without publishing its financials right away. OpenAI was last valued at about $852 billion, and analysts cited by TechCrunch expect a public valuation above $1 trillion. Goldman Sachs, Morgan Stanley and JPMorgan are reported to be leading the offering, with a listing possible as early as September.

OpenAI has been careful to say nothing is settled. The filing gives it the option to go public rather than an obligation, and the company has signalled it may stay private longer if that better suits its plans. That hedging matters, because the financial story underneath the headline is genuinely hard to read.

Growth against a very large bill

Whenever OpenAI does open its books, investors will have to weigh fast revenue growth against the enormous cost of building and running frontier models. The same tension hangs over Anthropic, which raised $65 billion at a valuation near $965 billion before filing, and over SpaceX, whose offering would rank as the largest in history if it completes.

What is striking is how quickly the mood has shifted. A year ago the open question was whether any of these companies would ever go public. Now three of the most closely watched names in the field are lining up at once, and the timing looks less like coincidence than a collective bet that the window is open. Whether public markets share that confidence is the one thing nobody can file in advance.
