A federal judge in California has made a ruling that issues surrounding Elon Musk’s usage of Ketamine cannot be brought up during a crucial jury trial in relation to his lawsuit with OpenAI.
This was made by Yvonne Gonzalez Rogers, a U.S. District Judge in Oakland, California, in advance of a highly publicized trial that is set to start on April 28. The trial is in relation to Musk’s allegations that OpenAI went against their original nonprofit objectives after he supported the firm financially in its early stages.
The upcoming trial is expected to cover the early days of OpenAI and how it came to have a falling out with Musk.
Musk and others, such as Sam Altman and Greg Brockman, founded OpenAI in 2015 and took it upon themselves to make it a nonprofit organization dedicated to creating artificial intelligence for the greater good of society.
Musk went on to donate about $38 million to the organization in its early days.
The jury will now be left to decide whether Altman and Brockman deceived Musk on OpenAI’s long-term strategy. Musk argues that they later changed the company into a for-profit business while reaping the benefits of huge commercial partnerships.
Musk vs. OpenAI, Judge Blocks Drug Claims in $134 Billion Lawsuit
One of the important events that the court will look into is the huge investment by Microsoft. The tech company has invested about $13 billion into OpenAI as part of a strategic partnership that has seen the company grow its AI infrastructure.
OpenAI’s legal team had argued that Musk’s use of ketamine could affect how jurors view his judgment during negotiations with the company.
However, Judge Rogers rejected that argument for now. She ruled that questions about Musk’s drug use would be irrelevant unless lawyers could show clear evidence that it affected his mental state during key discussions.
Without such proof, the issue cannot be raised before the jury.

This ruling removes a potentially controversial topic from the trial. Lawyers will instead focus on documents, communications, and testimony about OpenAI’s original mission and later shift in structure.
While Rogers blocked questions about ketamine, she allowed limited discussion about Musk’s attendance at Burning Man, the annual arts and culture festival held in Nevada’s desert.
OpenAI’s lawyers argued that several important communications between Musk and OpenAI leaders occurred while he was attending the event.
Because of that, the judge said lawyers can ask about the timing of those interactions. Still, the questions must stay narrow and focused on the communications themselves.
During a deposition in the case, Musk said he could not remember whether he had taken ketamine during certain negotiation periods.
Musk is seeking up to $134 billion in damages from OpenAI and Microsoft. If granted, the award would rank among the largest financial verdicts in U.S. history.
His claim argues that the companies benefited from a structure that departed from the nonprofit vision he believed he supported.
The High-Stakes Legal Battle Over AI’s Soul and Billions in Profits
OpenAI and Microsoft strongly deny the allegations. Both companies say Musk’s claims misunderstand the evolution of OpenAI’s structure and partnerships.
Even if the jury agrees with Musk, its role may be limited. The damages decision will likely be advisory, meaning the judge will make the final determination after the trial concludes.
Another point of tension involves the financial model used to estimate Musk’s damages.
Musk’s legal team relies on analysis from economist C. Paul Wazzan. Wazzan estimated that Musk could be owed between $79 billion and $134 billion in profits tied to OpenAI’s growth and Microsoft’s involvement.
Judge Rogers had expressed her doubts regarding the methodology adopted in that report. This shows that the calculations will be examined thoroughly at the trial.
The trial will feature major personalities of the technology industry as potential witnesses.
The list of potential witnesses will include Musk, Altman, Brockman, and Ilya Sutskever, who is the co-founder of OpenAI.
The trial will also feature executives of Microsoft as potential witnesses. The potential witnesses will include Satya Nadella, the current CEO of Microsoft, and Mira Murati, the former chief technology officer at OpenAI.
The trial will provide new insights into the development of OpenAI, which was initially a research laboratory but eventually became one of the most influential companies in the field of artificial intelligence. It will provide new insights into the early developments of the AI industry.
