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.
High-profile litigation involving OpenAI and Microsoft could affect OpenAI's corporate structure, IPO plans, partner relationships and the broader commercialisation and governance of foundational AI models—an outcome with material implications for firms using or partnering with LLM providers.

Musk Seeks Removal of OpenAI Officers in Lawsuit
Elon Musk is asking a federal court to remove OpenAI CEO Sam Altman and President Greg Brockman from their roles as officers and to revert OpenAI to an actual nonprofit as part of a lawsuit alleging fraud. Musk sued OpenAI and Altman in 2024, saying he was deceived into donating $38 million based on promises the organization would remain a nonprofit. In a recent legal filing his lawyers outlined remedies including removal of Altman as a nonprofit board director, removing both Altman and Brockman as officers of the for-profit arm, and returning allegedly ill-gotten gains — including amounts tied to lead investor Microsoft. OpenAI completed a 2023–2024 restructuring that leaves a nonprofit owning a 26% stake in the for-profit arm that operates ChatGPT. Jury selection is scheduled to begin April 27 in federal court in Oakland, California.
