Who owns OpenAI? Control and ownership

Who decides and who held which stakes are two separate questions.

Who owns Claude, Grok, and the others?

The same question for the other AI companies. Ownership and funding are listed separately, because an investor is not an owner.

Who owns which AI company?

Owners and control plus sourced investors per company. Each name links to its evidence.

An investor is not an owner. “No owner recorded” only means that no evidence is on file here, not that the company is independent. Amounts are invested, committed, or a conditional ceiling and are never added up.

Who depends on whom

Control, ownership, investment, compute contracts, distribution, and capital stay separate. Each line is a single piece of evidence. Other relationships can exist without being recorded here.

Who invested how much

Invested, committed, and conditional ceilings are not the same, so they are never added up. Each row stands on its own, with its own date and evidence.

Frequently asked questions about owners and investors

ChatGPT, OpenAI, Anthropic, and xAI in detail.

ChatGPT is a product of OpenAI. OpenAI Group PBC is controlled by the nonprofit OpenAI Foundation, which appoints its board. Its largest investors include Microsoft, SoftBank, and Amazon. Microsoft reports a stake of about 24% as of September 30, 2026, and SoftBank reports about 13% after its final tranche on October 1, 2026. Amazon reports a $50B investment as of September 30, 2026. None of these investors controls OpenAI.

No majority owner of Anthropic is on record on this map. Its investors include Amazon, Google, and Salesforce. Amazon reports investments of $8B and $5B as of September 30, 2026, plus conditional financing of up to $20B. On October 26, 2026, Anthropic filed for an initial public offering on Nasdaq under the ticker ANT. Google and NVIDIA have each committed to buy about $10B in shares right after it, conditional on the offering. This does not add up to a complete ownership register.

The OpenAI Foundation controls OpenAI Group PBC and appoints its board. The published 26% foundation, 27% Microsoft, and 47% employees and investors split refers to the recapitalization closing on October 28, 2025. The March 31, 2026 round closed with $122B in committed capital at an $852B valuation. After the final October 1, 2026 tranche, SoftBank reports $64.6B invested cumulatively and an approximately 13% stake. Microsoft reports only about 24% as of September 30, 2026. This does not establish a complete current ownership register.

The companies have not fully disclosed their investment motives. Google participated in Anthropic's 2023 Series C; the announcement does not state an amount. Google Cloud is also expanding TPU capacity for Anthropic. Amazon reports investments of $8B and $5B as of September 30, 2026, plus conditional financing of up to $20B. That last part has not been paid. These partnerships connect equity stakes with cloud business and compute capacity. Anthropic's separate purchases from AWS, Azure, and Google for compute are spending, not investments by those providers.

Since February 2, 2026, xAI has been a wholly owned subsidiary of SpaceX. It continues to exist as a subsidiary, but is no longer independently owned. SpaceX's current SEC filing describes xAI as part of its AI segment.

Every connection and every capital amount has its own evidence, a reference date, and a review date. The evidence consists of company announcements and filings with the US Securities and Exchange Commission, checked between October 7 and November 12, 2026. The stakes in OpenAI Group explicitly show the state on October 28, 2025. Amounts are never added up, because invested, committed, and conditional ceiling are different things.
