Musk Cross-Examined in OpenAI Trial
On April 29, 2026, Elon Musk continued testifying in his lawsuit challenging OpenAI’s conversion from a nonprofit to a for-profit structure. During a heated cross-examination by OpenAI attorney William Savitt, Musk said he lacked detailed knowledge of OpenAI’s internal safety efforts and was unsure what “safety cards” are. Musk reiterated that his roughly $38 million in early donations helped found OpenAI and said Microsoft’s reported $10 billion investment was a tipping point that eroded his trust in the organization. The case centers on claims of breach of charitable trust and unjust enrichment; Microsoft is also a named defendant. Judge Yvonne Gonzalez Rogers is overseeing a two-phase trial (liability then remedies). Musk’s testimony is expected to continue, and Jared Birchall is slated as the next witness.
How Elon Musk Left OpenAI, According to Greg Brockman
TechCrunch published Greg Brockman’s account of a 2017 dispute at OpenAI in which Elon Musk demanded full control of a proposed for-profit arm. Brockman testified at a 2026 trial, citing journal entries and contemporaneous details about a heated meeting where Musk reacted angrily when control was refused. Musk stopped regular donations and voluntarily left OpenAI’s board in February 2018, though he provided office space until 2020. The dispute preceded OpenAI’s 2019 creation of a for-profit entity and Microsoft’s subsequent $1 billion investment (followed by roughly $13 billion more over four years). Musk filed suit in 2024 alleging his co-founders misappropriated the nonprofit; the trial was ongoing as of the article’s May 6, 2026 publication.
