## Summary

On 8 June 2026 [Openai](/en/entity/openai) confirmed it had submitted a draft S-1 confidentially to the SEC, opening the door to a public listing as soon as Q4 2026 at a valuation reported near $1tn. The filing lands a week after [Anthropic](/en/entity/anthropic)'s confidential submission and days before [Spacex](/en/entity/spacex)'s Nasdaq debut; the three could become the largest IPOs on record. Goldman Sachs and Morgan Stanley lead. OpenAI stressed timing is undecided and the listing may slip, some restructuring is easier as a private company. The company last closed a $122bn round at an $852bn valuation in March, anchored by [Nvidia](/en/entity/nvidia), [Softbank](/en/entity/softbank) and Amazon, with [Microsoft](/en/entity/microsoft) continuing. Enterprise now exceeds 40% of revenue.

## By the numbers

- 8 Jun 2026, confidential S-1 submitted.
- ~$1tn, reported target valuation.
- $852bn, March 2026 round valuation.
- $122bn, committed in the March round.
- >40%, enterprise share of revenue.
- Goldman Sachs, Morgan Stanley, lead banks.

## Why it matters

A near-trillion-dollar listing would set the public-market benchmark for frontier-AI economics and force disclosure of OpenAI's loss profile, compute commitments and the non-profit/for-profit structure. Back-to-back with [Anthropic](/en/entity/anthropic) and [Spacex](/en/entity/spacex), it tests whether public investors will absorb three of the largest offerings ever inside one window, and whether AI capex can be financed on listed equity.

## What to watch

- Whether OpenAI converts the draft to a public S-1 or delays past Q4.
- First disclosed financials: revenue run-rate, losses, compute liabilities.
- How the non-profit-parent governance structure is presented to investors.
