Elon Musk’s civil suit against Sam Altman and OpenAI is reaching closing arguments, with testimony from key figures—especially cofounder Ilya Sutskever—likely to shape the outcome. Musk alleges OpenAI misled him to enable a for-profit shift that disadvantaged his xAI venture; OpenAI denies this and points to Musk’s prior efforts to exert control, including a 2018 bid to recruit Altman, Sutskever and other founders to run an AI unit inside Tesla. The disclosures highlight enduring tensions over governance, commercialization and AI safety at the heart of generative-AI’s rapid rise, with the trial set to clarify liability and potential remedies.
The trial could reshape governance norms and liability expectations for AI labs, affecting partnerships, funding and competitive dynamics. Tech leaders must watch outcomes that may influence board oversight, disclosure practices and commercialization strategies.

A deposition transcript from the Musk v. Altman case reveals that Ilya Sutskever circulated a 52-page memo to OpenAI’s independent directors shortly before Sam Altman’s November 2023 ouster, accusing Altman of deception and urging termination. Sutskever sent the memo via disappearing email and relied largely on secondhand claims from Mira Murati about Altman and Greg Brockman, which he did not independently verify. He admitted the board’s decision process was “rushed,” attributing it to the independent directors’ inexperience and uneven engagement with operations. Sutskever also said follow-ups he recommended — including interviews with specific employees — were not pursued. The deposition sheds light on internal governance failures and decision-making that nearly derailed a leading AI company.
A deposition transcript in Musk v. Altman reveals that Ilya Sutskever sent a secret 52-page memo to OpenAI’s independent directors alleging Sam Altman’s misconduct and recommending termination, using a disappearing email out of fear of leaks. Sutskever admitted much of the memo relied on secondhand claims from Mira Murati and that he did not verify allegations about Altman and Greg Brockman. He called the board’s decision process to remove Altman and Brockman “rushed,” attributing it to board inexperience and limited familiarity with OpenAI operations. The memo’s suggested follow-ups were largely not pursued, and Sutskever conceded hindsight about the risks of unverified information.
Elon Musk’s lawsuit against Sam Altman and OpenAI is approaching closing arguments as key witnesses — notably OpenAI cofounder and ex-chief scientist Ilya Sutskever, Microsoft CEO Satya Nadella, and Altman himself — are expected to testify. Musk alleges Altman and OpenAI misled him to shift the organization toward a for-profit model, a claim OpenAI denies, saying Musk seeks to slow them to benefit his xAI startup. Sutskever’s testimony is seen as potentially pivotal because of his central role in the 2023 ouster-and-reinstatement episode and his later departure; it could influence assessments of Altman’s credibility and commitment to AI safety. The civil trial will determine liability and possible remedies, not criminal guilt.
Elon Musk offered in 2018 to recruit OpenAI’s founders — Sam Altman, Greg Brockman and Ilya Sutskever — to run a new AI lab inside Tesla, proposing Altman join Tesla’s board or make OpenAI a Tesla subsidiary, evidence revealed during Musk’s high-profile trial with OpenAI. The disclosures surface amid disputes over control and OpenAI’s shift from nonprofit roots to a for-profit structure, which Musk has criticized as a conversion of a charity. OpenAI counters that Musk supported commercialization so long as he retained control. The revelation underscores past power struggles over governance and commercial strategy at the center of today’s generative-AI market.
