Private company
Who owns OpenAI
One company in the researched set discloses a stake in OpenAI, none of it sized by anyone who discloses it. OpenAI is private, so no 13F reports it: a 13F covers exchange listed positions only. These figures exist because each holder disclosed the stake in its own filings.

OpenAI is an artificial intelligence research and deployment company in San Francisco, founded in December 2015 by Sam Altman, Elon Musk, Ilya Sutskever, Greg Brockman and others with the stated aim of building artificial general intelligence that benefits humanity. It trains the GPT family of large language models and sells access to them through ChatGPT, a developer API, and tools including the Codex coding agent, the DALL-E image model and the Whisper speech recognition system, generating about $13.1 billion of revenue in 2025. Since a restructuring completed on 28 October 2025 it operates as OpenAI Group PBC, a Delaware public benefit corporation whose directors are appointed by the nonprofit OpenAI Foundation. Its central operational constraint is compute: through Stargate, an infrastructure programme run with Oracle and SoftBank, it is building data centres at Abilene and other Texas sites plus New Mexico and Ohio, a commitment of roughly 10 gigawatts and $500 billion.

OpenAI files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from Wikipedia: OpenAI, SoftBank Group: OpenAI, Oracle, and SoftBank expand Stargate with five new AI data center sites and Built In: OpenAI's Shift to a Public Benefit Corporation, Explained. The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- NVIDIA Corporation. Reported as a $30 billion commitment, described as the anchor of Nvidia's roughly $40 billion of 2026 AI equity bets. No share count, no share class, no percentage of OpenAI and no carrying value were disclosed in any source fetched here, so every quantitative field is left null rather than modelled. Nvidia's 10-Q for the quarter ended 26 Apr 2026 does not name any investee. Do not confuse this $30bn with the separate $30bn Intel position above: they are different holdings. source
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of OpenAI where a holder stated one, and are missing where no holder did.
