Has OpenAI filed for an IPO?

Yes — OpenAI confidentially submitted a draft S-1 to the SEC on June 8, 2026 and announced the filing itself. A confidential filing starts SEC review; the public S-1, roadshow, and pricing all still follow, and the company can pause at any stage.

When is the OpenAI IPO date?

There is no date. The June 2026 filing makes a late-2026 window (roughly September–November) possible, but late-June reporting said OpenAI is considering waiting until 2027, and the company says it has not decided. Any specific date circulating today is speculation.

What happened to OpenAI's capped-profit structure?

It ended with the October 2025 restructuring into OpenAI Group PBC, a Delaware public benefit corporation, with the OpenAI Foundation holding roughly 26% and retaining oversight. Employee PPUs are reported to convert one-for-one into PBC shares with the old return cap removed.

Do OpenAI employees owe tax when the IPO happens?

It depends on the instrument. PPU-to-share conversion is reportedly not a taxable event — basis and holding period carry over. Tax generally arises when holders sell (in a tender or post-IPO) or if any grant-specific term creates income at conversion or settlement. Individual grant documents and 83(b) status control; this is CPA territory.

What is Sam Altman's equity in OpenAI?

Reported as 'none/pending' — a formal grant has been discussed but not completed per public reporting. Any grant at current valuations would dilute existing holders, which makes it a watched item ahead of the public S-1.

The OpenAI IPO: filed, but not scheduled

The S-1 went in on June 8, 2026. What hasn't happened: a public filing, a roadshow, a date. A late-2026 listing is possible; reporting says 2027 is genuinely on the table; the company says it hasn't decided.¹^,² Here's the honest state of the event — and why holders should plan as if the date doesn't matter.

The timeline so far

October 2025 — restructuring completed. OpenAI Group PBC is created; the Foundation retains oversight and ~26%. The capped-profit era ends; PPUs are reported to convert one-for-one into PBC shares.²^,³
October 2025 — ~$6.6B tender. The largest of the investor-led secondaries: 600+ current and former employees, per-person cap reported at $30 million.²
March 2026 — ~$852B primary round. The last disclosed valuation mark.²
June 8, 2026 — confidential S-1. Announced by OpenAI itself.¹
Late June 2026 — timing wobble. Reporting says the company is weighing whether to list in late 2026 or wait until 2027. No decision announced since.²

Why the date is genuinely uncertain

A confidential S-1 is an option, not a commitment. OpenAI can sit in SEC review, refresh financials, and choose its window — and unlike a cash-hungry issuer, reporting doesn't suggest it needs public capital on a clock. The practical read for holders: a September–November 2026 listing and a 2027 listing are both live scenarios. Planning that depends on one of them is planning that might be wrong; planning that works in both is the goal.

What to watch when the S-1 goes public

The lockup section. Uniform 180 days or staggered unlocks (as SpaceX used in June 2026)? This sets every post-IPO selling decision.
Conversion disclosure. The definitive description of how PPUs became PBC shares — basis, holding periods, and any grant-year wrinkles. Reported mechanics today: basis carries, vesting carries, holding period carries, cap removed, no taxable sale at conversion.³^,⁴
The Altman grant. CEO equity is reported as "none/pending"; a grant at current valuations would be visible dilution and is a watched pre-S-1 item.²
Audited financials. First authoritative numbers, replacing round-mark arithmetic.

The holder's plan that works in both scenarios

Resolve your conversion facts now. Basis, 83(b) history, holding-period start dates — collect the paper before any event compresses the timeline.
Treat tenders as the liquidity program until proven otherwise. If the IPO slips to 2027, a further secondary window becomes the interim opportunity — the sizing framework is on the tender page.
Write the concentration policy before the market exists. Decide your target holding as a percentage of net worth while it's still an abstraction; execute on the rule later.
Model the tax both ways. A 2026 sale vs a 2027 sale can land in different bracket years. The calculator handles ordinary vs long-term treatment with your numbers.
