What company owns ChatGPT?

OpenAI Group PBC

ChatGPT is made by OpenAI, which since October 2025 has been two linked entities: the nonprofit OpenAI Foundation, and the for-profit OpenAI Group PBC — a public benefit corporation legally required to advance its stated mission, not only to make money. The Foundation controls the Group and appoints its entire board. Microsoft holds roughly 27% of the equity but none of that control. There is no public listing and no ticker.

PER VENDOR DOCS · AUG 21, 2026

The equity and the control are held by different people.

OpenAI publishes its own structure page, and the arrangement it describes is unusual enough to be worth reading carefully. OpenAI was founded in 2015 as a nonprofit; in 2019 it created a for-profit subsidiary to raise capital. On 28 October 2025 that arrangement was recapitalised: the nonprofit became the OpenAI Foundation and the for-profit became OpenAI Group PBC, a public benefit corporation that is — in OpenAI's words — "required to advance its stated mission and consider the broader interests of all stakeholders".

The equity split at closing: the OpenAI Foundation holds 26%, worth approximately $130 billion at the Group's valuation at the time; Microsoft holds roughly 27%; the remaining 47% sits with current and former employees and investors. The Foundation also holds a warrant that pays out significant additional equity if the Group's share price rises more than tenfold within 15 years.

The control does not follow the equity. Through special voting and governance rights held solely by the Foundation, it appoints all members of the OpenAI Group board and can replace them at any time. So the single largest equity holder — Microsoft, at about 27% — has more stock than the Foundation and none of its governance power. That is the fact most "who owns ChatGPT" answers get wrong by reporting only the percentages.

The Foundation's board is named publicly: Bret Taylor (Chair), Adam D'Angelo, Dr Sue Desmond-Hellmann, Dr Zico Kolter, Retired U.S. Army General Paul M. Nakasone, Adebayo Ogunlesi and Nicole Seligman, plus CEO Sam Altman. The Safety and Security Committee remains a committee of the Foundation, chaired by Dr Kolter.

§ 02 / WHY

The three questions behind this one.

2.1
"Is OpenAI the same as ChatGPT?"

No. OpenAI is the company; ChatGPT is one of its products. The same company also sells API access to its models, the Codex coding agent, and — until its announced shutdown — Sora.

The distinction is not pedantry, because the products have different terms. Content from ChatGPT Business, Enterprise and the API platform is not used to train models by default; content from personal ChatGPT accounts may be, unless you opt out. Same company, different defaults, depending on which door you came in through.

2.2
"Does Microsoft own ChatGPT?"

No, and the answer is more interesting than a flat denial. Microsoft is the largest single equity holder at roughly 27% — more stock than the nonprofit that controls the company — and has backed OpenAI since 2019. But equity is not control here: the Foundation appoints and can replace every director of OpenAI Group.

Microsoft also ships its own assistant, Copilot, which has drawn on OpenAI models. That is a commercial relationship rather than ownership of ChatGPT, and the two products are separately priced and separately governed — we compare them on Copilot vs ChatGPT.

2.3
"Can I buy shares in ChatGPT?"

No. There is no public listing and no ticker symbol. Per OpenAI's own structure page, the equity in OpenAI Group PBC is held by the OpenAI Foundation, Microsoft, and current and former employees and investors. None of it trades on a public exchange.

This matters beyond curiosity, because how to invest in ChatGPT is precisely the query that fake-share and pre-IPO-allocation scams target. If a site offers you OpenAI or ChatGPT stock, it is not selling what it claims to be selling.

We are not licensed to give investment advice and are not going to, here or anywhere else on this site. What we will say is the factual part: as of 21 August 2026, no publicly traded security represents ownership of ChatGPT.

2.4
Why the structure is worth knowing as a customer

A public benefit corporation carries a legal obligation to weigh its stated mission alongside shareholder returns, which is a genuinely different constraint from a conventional company's. Whether that changes anything you experience as a user is a fair question, and not one we can answer for you.

What it does explain is the shape of some decisions that otherwise look commercially odd — retiring products with published notice periods and export windows, publishing detailed data-use documentation, and separating training defaults by plan type. Those are the sort of commitments that a governance structure makes harder to quietly reverse.

Q · 01 Who owns ChatGPT? +
OpenAI Group PBC, a public benefit corporation, which is controlled by the nonprofit OpenAI Foundation. At the October 2025 recapitalization the Foundation held 26% of the equity, Microsoft roughly 27%, and current and former employees and investors the remaining 47%.
Q · 02 Is ChatGPT publicly traded? +
No. There is no ticker symbol and no public listing. Equity in OpenAI Group PBC is held privately by the OpenAI Foundation, Microsoft, and current and former employees and investors.
Q · 03 Can I buy OpenAI stock? +
Not on a public exchange — no such security exists. Be careful here: this exact question is targeted by fake-share and pre-IPO-allocation scams. We are not licensed to give investment advice and offer none; the factual answer is that ChatGPT ownership is not publicly tradable.
Q · 04 Does Microsoft own OpenAI? +
No. Microsoft held roughly 27% of OpenAI Group PBC at the recapitalization — the largest single stake — but the OpenAI Foundation holds special voting rights that let it appoint and replace every director of OpenAI Group at any time.
Q · 05 Is OpenAI a nonprofit or a company? +
Both, by design. OpenAI Foundation is the nonprofit and OpenAI Group PBC is the for-profit public benefit corporation it controls. The structure dates from 28 October 2025 and replaced the 2019 arrangement of a nonprofit with a for-profit subsidiary.
