OpenAI reportedly readies confidential IPO filing

The biggest AI giant in the world is about to test public market waters.

OpenAI is gearing up to confidentially file draft IPO paperwork with the SEC as early as May 22, according to reports from The Wall Street Journal and CNBC on May 20. Wall Street heavyweights Goldman Sachs and Morgan Stanley are reportedly leading the charge on drafting the prospectus.

OpenAI was recently pegged at over $850 billion in private rounds, with one recent round citing an $852 billion valuation. If completed, the listing would become one of the largest IPOs ever seen, trailing only Elon Musk's SpaceX.

A crowded race to Wall Street

OpenAI's spokesperson kept things close to the vest, stating that the company regularly evaluates strategic options as part of normal governance and remains focused on execution. Still, CFO Sarah Friar dropped hints last month on CNBC, calling it healthy practice for a firm of OpenAI's size to look and act like a public company.

Timing remains fluid. CNBC previously reported the IPO could land in the fourth quarter, while other outlets cite a potential listing window kicking off as soon as September.

OpenAI isn't running alone. SpaceX, which merged with xAI earlier this year and notched a $1.25 trillion valuation in February, filed confidentially last month and could unveil its public prospectus as soon as May 21. Rival Anthropic is also eyeing its own public debut.

OpenAI just cleared a critical legal hurdle after winning a lawsuit brought by co-founder Elon Musk over its shift from a nonprofit to a for-profit business, though Musk plans to appeal. Meanwhile, reports note OpenAI recently missed internal revenue and user targets.

Why it matters

We think this confidential filing marks the moment the generative AI gold rush transitions from venture-backed experimentation to Wall Street quarterly discipline.

For enterprise users and developers, an OpenAI under public scrutiny will likely care far more about margins. That means we should expect tighter monetization on advanced frontier models, less tolerance for money-losing research projects, and potentially less generous free tiers. If you rely heavily on their infrastructure, keeping an eye on API pricing adjustments should be on your radar.

For the wider tech landscape, this sets up a historic capital vacuum. With SpaceX and OpenAI racing to Wall Street, public markets will face unprecedented liquidity tests, likely squeezing late-stage funding for smaller competitors who haven't proved their unit economics.

OpenAI's move to file confidentially looks clever because it allows them to quietly iron out their governance and restructuring quirks with the SEC away from the media circus. But the red flags are clear: jumping onto public exchanges right after missing internal growth targets, with Musk still threatening appeals, means they will have zero margin for execution error once the books go wide open.
