Eight days after Anthropic, **OpenAI** said — via a post on X on 8 June 2026 — that it has submitted a **confidential S-1** to begin its own path to a public listing. Two of the most valuable private companies in the world are now in the IPO queue within a week of each other, which turns the question from *if* to *who first, and at what price*.

## The reported numbers

Coverage puts the target valuation at roughly **$730B–$850B**, though some reports stretch toward **~$1 trillion** — the spread itself tells you these are estimates, not disclosed figures. Underwriters are reported as **Goldman Sachs and Morgan Stanley**, with JPMorgan also named. A debut could land somewhere in **September–November 2026**, but OpenAI has been explicit that the timing is undecided.

> **Key:** **The bigger picture:** Bloomberg has reported an AI-IPO pipeline of roughly **$3.6 trillion** in aggregate. Two confidential filings in eight days are the leading edge of that wave — and the public markets are about to find out whether they'll fund it at these multiples.

## What it means

The strategic read is straightforward: neither lab wants to be the one that lists *second* into a saturated market, so filing early is a way to keep optionality and set the narrative. For everyone else, the sequencing matters — the first prospectus to go fully public will set the comparables every later AI listing is judged against. Until then, every figure here should carry its 'reported' label.

## Key takeaways

- OpenAI confirmed a confidential S-1 via X on 8 June 2026 — roughly a week after Anthropic.
- Reported target is ~$730B–$850B; some outlets stretch toward ~$1T, so the figure varies.
- Underwriters are reported as Goldman Sachs and Morgan Stanley (JPMorgan also named).
- A debut is possible Sept–Nov 2026, but OpenAI says timing is explicitly undecided.
