The ongoing legal battle between Elon Musk and OpenAI intensified this week as the billionaire entrepreneur faced a rigorous second day of cross-examination in a high-profile trial. The case revolves around Musk’s lawsuit accusing the AI firm of deviating from its original mission to develop artificial intelligence for the broader benefit of humanity.
The courtroom exchanges, held in a federal court in Oakland, California, have drawn global attention given the prominence of the individuals and organizations involved, including Sam Altman and Greg Brockman.
Elon Musk, one of the co-founders of OpenAI, claims that he contributed $38 million to the organization under the belief that it would remain a nonprofit focused on safe and ethical AI development. According to his lawsuit, the company later shifted toward a for-profit structure, allegedly prioritizing financial gain over its founding principles.
He has accused OpenAI’s leadership of misleading him about their intentions and argues that the transition undermines the organization’s original mission.
OpenAI, however, has strongly rejected Musk’s claims. The company asserts that Musk’s legal action is motivated by personal grievances, including his departure from the board in 2018 and dissatisfaction with OpenAI’s rapid growth and success.
The firm also argues that Musk himself had, at times, supported the idea of a for-profit model and was kept informed about key developments, including investments from Microsoft.
During cross-examination, OpenAI’s lawyer William Savitt pressed Musk on whether he had reviewed critical documents related to the company’s structural transition. In particular, he was asked about a term sheet sent by Sam Altman on August 31, 2017, outlining plans for a hybrid structure—combining nonprofit oversight with a for-profit arm.
Musk responded candidly:
”My testimony is I didn’t read the fine print, just the headline,” said Musk, wearing a dark suit, dark solid tie and white shirt.
This statement became a focal point in the proceedings, raising questions about Musk’s awareness and involvement in key decisions at the time.
At several points, Musk appeared visibly frustrated with the pace and style of questioning. The exchanges grew tense as interruptions occurred during his responses.
He remarked:
”Few answers are going to be complete, especially when you cut me off all the time,” Musk said.
Such moments highlighted the intensity of the legal confrontation and the high stakes involved in the case.
The questioning also revisited earlier evidence, including emails and text messages from 2017. These communications suggested that Musk had, at times, been open to the idea of a for-profit structure and was informed about potential partnerships and investments.
Musk is seeking $150 billion in damages from OpenAI and Microsoft, making this one of the largest legal claims in the tech industry. He has requested that the compensation be directed toward OpenAI’s charitable arm.
Founded in 2015, OpenAI has evolved significantly over the past decade. What began as a nonprofit research initiative operating out of Brockman’s apartment has grown into a global AI powerhouse valued at over $850 billion.
The company’s transition to a capped-profit model enabled it to attract large-scale investments, particularly from Microsoft, to fund advanced AI research, computing infrastructure, and talent acquisition.
The trial, which began earlier this week, is expected to continue for several weeks. After Musk’s testimony, the court is likely to hear from:
Additionally, legal representatives from Microsoft are expected to question Musk, adding another layer of complexity to the proceedings.
The legal battle between Elon Musk and OpenAI underscores broader tensions in the rapidly evolving AI industry—particularly the balance between ethical responsibility and commercial viability. As artificial intelligence becomes increasingly central to global innovation, disputes like this highlight the challenges of aligning long-term missions with the realities of funding and growth.
While the outcome of the trial remains uncertain, its implications could shape the governance, funding models, and ethical frameworks of AI organizations worldwide. The case serves as a pivotal moment in defining how the future of artificial intelligence will be structured and controlled.
