Oakland: A high-profile OpenAI lawsuit has gone to trial in California, marking a major escalation in the long-running dispute between Elon Musk and Sam Altman.
The case, being heard in a federal court in Oakland, centres on Musk’s claims that OpenAI’s leadership abandoned its original non-profit mission in favour of a profit-driven model. Musk alleges that Altman, along with OpenAI president Greg Brockman and partner Microsoft, breached their founding agreement.
According to Musk, the transition of OpenAI into a for-profit structure contradicts its original purpose of developing artificial intelligence for the benefit of humanity. He is seeking significant damages and structural changes to the organisation.
The lawsuit also includes claims of unjust enrichment, with Musk arguing that OpenAI executives have benefited financially from the shift. Among his demands are the removal of key leadership figures and a reversal of the company’s for-profit restructuring.
OpenAI has strongly denied the allegations, stating that Musk had previously agreed that creating a for-profit entity would be necessary to secure funding and advance its technology. The company has also argued that Musk’s financial contributions were donations, not investments, and do not grant him ownership rights.

The trial is expected to feature testimony from major figures in the tech industry, including Musk, Altman and Satya Nadella, highlighting the significance of the case. The dispute dates back to 2017, when tensions grew between Musk and OpenAI’s leadership over the company’s direction. Musk later left the board in 2018 and ended his involvement.
Since then, OpenAI has experienced rapid growth, launching widely used technologies such as ChatGPT and securing substantial investment from Microsoft. The company is now among the most valuable private firms globally and is reportedly preparing for a public listing.
The OpenAI lawsuit carries major implications for the future of artificial intelligence governance, corporate structure and investor influence in the tech sector.
Industry observers say the outcome could shape how AI companies balance public-interest missions with commercial growth.
As the trial unfolds over the coming weeks, it is expected to draw intense global attention, given the influence of both Musk and Altman in the rapidly evolving AI landscape.
