- The lawsuit demands $150 billion in damages and the ousting of Sam Altman and Greg Brockman from their positions

The long-anticipated legal confrontation between Elon Musk and OpenAI has arrived. The US District Court for the Northern District of California commenced jury selection on Monday, with opening statements scheduled for Tuesday.
Musk was among the original founders of OpenAI in 2015, working alongside Sam Altman and Greg Brockman to establish the organization. According to his complaint, he contributed more than $44 million under the premise that OpenAI would maintain its nonprofit status. However, legal filings indicate his actual contributions totaled approximately $38 million during the 2016-2020 period.
The lawsuit centers on OpenAI’s 2019 restructuring into a for-profit entity, which Musk alleges occurred without his knowledge. He’s pursuing $150 billion in damages from both OpenAI and Microsoft, with any recovered funds designated for OpenAI’s charitable division.
Beyond financial compensation, Musk demands OpenAI return to its nonprofit roots. His legal action calls for the dismissal of both Altman and Brockman as company officers, along with Altman’s removal from the board of directors.
The witness roster features prominent Silicon Valley figures. Elon Musk, Sam Altman, and Microsoft’s CEO Satya Nadella will all provide in-person testimony. Shivon Zilis, who previously served on OpenAI’s board and is the mother of four children with Musk, is anticipated to deliver critical testimony.
Previously confidential documents emerging from the litigation expose early friction among OpenAI’s founding members. A 2017 diary entry by Brockman questioned: “This is the only chance we have to get out from Elon. Is he the ‘glorious leader’ that I would pick?”
In January 2018, Musk warned colleagues via email that “OpenAI is on a path of certain failure relative to Google.” He departed from the board soon thereafter.
The Corporate Restructuring Controversy
OpenAI transformed into a for-profit subsidiary in 2019, remaining under nonprofit oversight. By October 2025, it had evolved into a public benefit corporation. Microsoft acquired a 27% ownership position. The nonprofit entity received equity valued at $130 billion.
OpenAI’s latest fundraising effort established an $852 billion company valuation.
OpenAI maintains that Musk was fully aware of the for-profit conversion plans and actually proposed merging OpenAI with Tesla while positioning himself as CEO. According to OpenAI’s defense, when Altman and Brockman rejected this proposal, Musk departed and launched his competing AI venture, xAI.
Microsoft refutes allegations of conspiracy with OpenAI, asserting its partnership began only after Musk’s exit from the organization.
The Stakes and Potential Consequences
This legal proceeding threatens to impact OpenAI’s IPO strategy, which could establish a $1 trillion company valuation. A series of potentially damaging revelations might obstruct that trajectory.
The jury will deliver an advisory verdict only. US District Judge Yvonne Gonzalez Rogers maintains final authority over the outcome. Should defendants be found liable, she possesses the power to mandate OpenAI’s reversal of its for-profit conversion.
The trial is projected to continue until mid-May.
