Musk co-founded OpenAI in December 2015 alongside Sam Altman, Greg Brockman, Ilya Sutskever and others, structuring it explicitly as a nonprofit research lab with a stated mission to ensure that artificial general intelligence benefits humanity as a whole, rather than being controlled by a single company or government.[1][2] Musk pledged to help fund the effort, and OpenAI's early public statements framed the nonprofit structure as central to its mission: research would be shared openly, and no single entity would control powerful AI systems for private gain.[1][2]
01
At a Glance
Elon Musk co-founded OpenAI in December 2015 as a nonprofit artificial-intelligence research lab, alongside Sam Altman and others, intending it as a counterweight to AI development concentrated inside large, closed technology companies. Musk pledged significant funding and served on its board until February 2018, when he departed, citing a conflict of interest with Tesla's own AI work; he stopped making the pledged donations around the same time. As OpenAI restructured around a 'capped-profit' subsidiary and later moved further toward a conventional for-profit structure while building close ties with Microsoft, Musk became an outspoken critic, ultimately suing OpenAI and Altman in 2024 alleging they had abandoned the nonprofit's founding charitable mission. A federal jury ruled against Musk in May 2026, finding his claims were barred by the statute of limitations; Musk has said he will appeal.

03
Musk's 2018 Departure
Musk left OpenAI's board in February 2018. OpenAI's public statement at the time cited a potential conflict of interest as Tesla increasingly focused on AI for self-driving cars, since Musk would eventually be competing for some of the same AI talent OpenAI needed.[2][3] Musk has since given additional context in various interviews, including disagreements over the direction of the organization and his degree of control.[3] He also stopped fulfilling a pledged multi-year donation to OpenAI following his departure, a point later raised in the 2024 lawsuit's factual background.[3]
04
OpenAI's Shift and Musk's Criticism
In 2019, OpenAI restructured around a "capped-profit" subsidiary to attract the large-scale investment needed for frontier AI research, taking a major investment from Microsoft. Musk became an increasingly vocal public critic in subsequent years, arguing OpenAI had drifted from its founding nonprofit, open, safety-focused mission toward a closed, commercially driven operation effectively controlled by Microsoft.[3][4] Musk founded his own AI company, xAI, in 2023, positioning it partly as the "truth-seeking," safety-focused alternative he said OpenAI had failed to remain.[4]
05
The Lawsuit and 2026 Verdict
In 2024, Musk sued OpenAI and Sam Altman, alleging breach of an agreement to operate OpenAI strictly as a charitable, open-research nonprofit, and seeking, among other remedies, to block OpenAI's further conversion to a conventional for-profit structure.[5][6] A federal jury trial began in spring 2026, and on May 18, 2026, the jury found in favor of OpenAI and Altman, concluding that Musk had waited too long to bring his claims under the relevant statute of limitations, without ruling on the underlying merits of whether OpenAI had breached a charitable trust.[6][7] Musk's attorney said the case was "not over" and that Musk intended to appeal to the 9th Circuit Court of Appeals.[7]
