The legal battle between Tesla and SpaceX CEO Elon Musk and OpenAI CEO Sam Altman entered its fourth day of critical courtroom testimony.

According to Reuters, Musk admitted on the stand that he “did not read the fine print” when signing documents related to OpenAI’s transition from a nonprofit organization to a for-profit entity. This testimony emerged as a key focal point of the trial.

Business Insider highlighted four key takeaways from day four of the proceedings, including testimony from Musk’s money manager. The trial has revealed deep divisions between the two tech leaders on AI development trajectories and corporate governance philosophy.

Notably, the judge reminded both sides’ lawyers that AI technology itself is not on trial — the case centers on corporate governance and the interpretation of legal contracts. NBC News reported that the judge’s statement aims to keep the proceedings focused on legal issues rather than broader AI debates.

The New York Times analysis noted that Musk’s claims about AI dangers face limits in the courtroom. As a co-founder of OpenAI, Musk left the organization in 2018 and subsequently founded rival company xAI. His core legal argument seeks to block OpenAI’s for-profit transition.

CNN previously reported that this landmark tech showdown began this week, with court proceedings shedding light on the collaboration and conflicts between the two sides during OpenAI’s early days. As the trial progresses, more information about AI industry internal governance structures is being made public.
