Musk vs. OpenAI: Trial Over Nonprofit Roots and For-Profit Shift
5/18/2026, 10:53:20 AM
The Lawsuit and Core Claims
Elon Musk sued OpenAI, its chief executive Sam Altman and president Greg Brockman in a U.S. District Court in Oakland, alleging breach of charitable trust and unjust enrichment. Musk says the $38 million (CNBC) or $44 million (CryptoBriefing) he donated was misused after OpenAI shifted to a capped-profit model and partnered with Microsoft. He seeks to revert OpenAI to nonprofit status and damages of $130 billion to $134 billion.
Background & Context
OpenAI launched in December 2015 as a nonprofit research lab co-founded by Musk, Altman and others to keep AI development open. Musk pledged up to $1 billion but contributed about $38–$44 million. Tensions grew in 2017 over control and a Tesla hire, leading Musk to leave the board in 2018. Microsoft’s $10 billion 2023 investment deepened the commercial shift, prompting Musk to start xAI in 2023.
Timeline of Key Events
Key dates: May 2015 – Altman proposes AI “Manhattan Project” to Musk; Dec 2015 – OpenAI nonprofit launch; June 2017 – Musk demands control; 2018 – Musk exits board; Jan 2023 – Microsoft invests $10 billion; Feb 2024 – Musk files suit; Apr 27-30 2026 – trial; May 18 2026 – jury deliberates.
Data & Statistics
OpenAI is valued >$850 billion; Musk’s donation $38–$44 million; Microsoft pledged $13 billion; damages sought $130–$134 billion.
Why It Matters
A ruling could set a precedent for nonprofit entities that later adopt profit-driven structures, shaping AI governance, investor risk assessments, and the future of public-private partnerships in high-impact technology.
Official Statements, Responses, and Criticism
Musk’s attorney Steven Molo told jurors, “A non-profit devoted to safe AI… you’re supposed to buy that.” OpenAI counsel Sarah Eddy replied, “Even the people who work for him… can’t back his story.” UC Berkeley professor Stavros Gadinis warned the public may see both as “dueling stewards of transformative technology.” Critics note no binding contract locked OpenAI to a nonprofit model and question Musk’s motives given his for-profit xAI venture.
Conflicting Reports & Gaps
Sources differ on Musk’s exact donation ($38 million vs $44 million) and on the damages sought ($130 billion vs $134 billion). The court has not yet ruled on whether the 2024 filing meets the statutory limitation period.
