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.
A high-profile governance and legal dispute involving OpenAI and Elon Musk could influence leadership accountability, funding narratives, and public scrutiny of major AI labs—relevant to broader AI industry dynamics though not an immediate AdTech change.

Musk vs OpenAI Trial Reveals Control and Donation Dispute
During the second week of the Elon Musk v. OpenAI trial, OpenAI president Greg Brockman testified that Musk pushed the company to create a for‑profit arm and sought “absolute control” over it. Musk previously testified that OpenAI CEO Sam Altman and Brockman deceived him into donating $38 million by promising to keep the organization nonprofit; OpenAI later accepted large investments from Microsoft and restructured to operate a for‑profit subsidiary. The court proceedings have included testimony, diary excerpts and other witness accounts; the trial is occurring as OpenAI plans a public listing. The reporting is an MIT Technology Review analysis republished on t3n and was written by Michelle Kim (published 2026‑05‑11).
Elon Musk Accuses Sam Altman of 'Plundering' OpenAI
At the opening of a civil trial in Oakland on April 29, 2026, Elon Musk accused OpenAI’s leadership—specifically CEO Sam Altman and board chair Greg Brockman—of converting OpenAI away from its original non‑profit mission for personal gain and demanded the company be returned to non‑profit status. Musk’s filing alleges he was misled about how his earlier donations would be used and reportedly seeks $150 billion in damages. The suit also names Microsoft; Microsoft denies any prior collusion with OpenAI and its CEO Satya Nadella is expected to testify. The article notes OpenAI’s corporate evolution (2015 non‑profit founding, later creation of OpenAI LP, and more recently conversion of OpenAI LP into a Public Benefit Corporation) and that judges cautioned Musk to curb public commentary about the case. The dispute comes as OpenAI pursues an IPO and Musk’s xAI competes in the AI market.
