OpenAI and Elon Musk: Founding, Departure and a Later Legal Dispute

In this March 2023 video, I revisit OpenAI’s founding and its difficult relationship with Elon Musk. I describe the conflict as a struggle over control and the direction of AI. The participants’ motives are contested, and subsequent disclosures and court proceedings should be separated from what was known when the video appeared.

OpenAI publicly launched in December 2015 as a nonprofit research organization with a mission to develop AI for broad human benefit. Its announcement named Sam Altman and Elon Musk as co-chairs and included Reid Hoffman among supporters. It described $1 billion in commitments from the group of funders, not an established $1 billion personal donation by Musk. Openness was part of the organization’s public vision, though that does not mean every subsequent system was released under an open-source license.

I describe OpenAI recruiting prominent researchers including Wojciech Zaremba and the high compensation required to attract talent. By 2018, I say Musk feared the organization was falling behind Google and proposed taking control. This is a retrospective account of private negotiations, not an independently established account of everyone’s motives.

I say the other founders rejected Musk’s proposal and that he departed. In later statements published in 2024, OpenAI said the parties had discussed a for-profit structure, that Musk sought control and proposed bringing OpenAI into Tesla, and that the team rejected those terms. Those statements include selected emails and represent OpenAI’s account; Musk disputed the organization’s later direction.

The video says Musk had already given $100 million and reneged on a personal $1 billion donation. OpenAI later said he contributed less than $45 million and published an email in which he offered to cover what other funders did not provide toward a proposed commitment. The exact characterization of promises and decisions is disputed; the collective 2015 announcement should not be described as a completed personal donation.

Musk left the OpenAI board in February 2018. The organization’s announcement at the time cited a potential future conflict with Tesla and said he would continue to advise and donate. The later account of disagreements over control should not be treated as though it was the sole explanation publicly announced in 2018.

The video connects the departure with OpenAI’s move toward a for-profit and the Microsoft relationship. The chronology matters: OpenAI LP was announced in March 2019 as a capped-profit company controlled by the nonprofit, and the Microsoft investment followed later in 2019. Those steps came after Musk left the board, even though commercial options had been discussed earlier.

ChatGPT launched in late 2022 and brought OpenAI to a much wider audience. By the time of the video, Musk was publicly criticizing OpenAI’s commercial structure, the openness of its technology and its ties to Microsoft. I speculate about whether his motives include jealousy or concern for AI safety; those motives cannot be determined from the events alone.

The video discusses reports that Musk was assembling a competing AI effort. xAI was publicly announced in July 2023, after this March video, so its launch should not be placed before the recording. I also claim Microsoft had exclusive access to OpenAI’s entire codebase; the precise terms and scope of intellectual-property access are contractual matters and are not established by that broad assertion.

I note that Altman said he held no equity in OpenAI’s for-profit at the time, and describe his view that Musk cares about humanity while having other motives for criticizing OpenAI. These are historical statements and interpretations, not findings about either person’s intentions.

The dispute continued after the video. In 2024 Musk sued, alleging that OpenAI and its leaders had departed from the nonprofit mission; OpenAI denied the claims and offered its own account of the earlier negotiations. On May 18, 2026, an advisory jury found the claims untimely, and the federal judge accepted that finding and dismissed them. A limitations ruling is not a determination that every competing account of the founding and split has been proven or disproven.
