A California federal judge had little patience for an OpenAI co-founder trying to limit his forced participation in Elon Musk's lawsuit challenging the ChatGPT maker's transition to a for-profit structure, admonishing the former executive for contesting a magistrate judge's order with motions filed while federal courts work unpaid.
U.S. District Judge Yvonne Gonzalez Rogers, in just a few pages, on Friday held nonparty Ilya Sutskever to the order requiring the former executive to sit for another deposition to discuss his financial stake in OpenAI and to produce a memo he sent to members of the artificial intelligence company's board ahead of a decision to remove Greg Brockman as board chairman.
Judge Gonzalez Rogers said U.S. Magistrate Judge Thomas S. Hixson rightly deemed both the memo and Sutskever's financial stake — estimated by Musk to be in the "billions" — relevant to the case in which Musk alleges he was duped into donating tens of millions of dollars to OpenAI on the promise the company would remain a nonprofit, only for it to seek to convert into a for-profit structure. OpenAI finalized that transition last week, with the nonprofit OpenAI Foundation maintaining control over the for-profit entity.
In rejecting Sutskever's motion for relief from the magistrate judge's order and refusing to stay that mandate, Judge Gonzalez Rogers noted the extraordinary circumstances under which federal courts must now address such filings.
"The court reminds the parties that due to the government shutdown funding for the federal judiciary has lapsed and court staff are working without payment. Where possible, the parties should resolve discovery disputes without court intervention," Judge Gonzalez Rogers said in a footnote. "Having now reviewed the merits of this allegedly emergency motion, Sutskever should not have filed the instant motions, especially given the standard of review. Counsel shall exercise more restraint in the future."
A source familiar with the matter confirmed Sutskever has produced the Brockman memo and has agreed to sit for a new deposition by a Nov. 5 deadline. His initial reticence had prompted Musk to try and tee up contempt proceedings against the former executive, only for Judge Hixson to refuse last week, asserting that Sutskever can't be in contempt because the magistrate judge never set a deadline for compliance.
Reviewing Judge Hixson's mandates on an "extremely deferential" standard, Judge Gonzalez Rogers agreed Friday that "Sutskever's financial interest in OpenAI is directly relevant to bias, particularly if Sutskever retained a large interest in the company (as a co-founder) after his departure."
Generally saying he'd held onto a financial stake, and that it had gone up, "is too general to be of any benefit," she said. She also admonished Sutskever for contending the magistrate judge violated his right to privacy.
"[Judge Hixson] did not act 'contrary to law' in determining that Sutskever's privacy interest was not sufficiently compelling, particularly when compared to the information's relevance to this case. Preferring one conclusion does not make the other contrary to law," Judge Gonzalez Rogers said.
Nor was Judge Gonzalez Rogers persuaded by Sutskever's request for more safeguards because Musk's lawyers disclosed in his first deposition the value of another OpenAI executive's financial stake. The judge called that disclosure "inadvertent," noted the question was withdrawn and pointed to the protective order covering sensitive information in the case, allowing it be shared only with outside counsel.
The judge was also dismissive of arguments that Musk signed away his right to the Brockman memo when agreeing to narrow the scope of Sutskever's subpoena.
"Sutskever's counsel agreed to produce categories of documents that appear, on their face, relevant to the Brockman memo," Judge Gonzalez Rogers said, such as on OpenAI's founding and safety, and potential conflicts of interest for Brockman.
"Moreover, Magistrate Judge Hixson did not commit clear error in deferring to the plaintiffs' explanation that they believed that the Brockman memo was 'self-deleting' and could not be discovered until Sutskever revealed at his deposition that he had retained the document. … That is a reasonable conclusion to draw," the judge said. "Sutskever's argument that Magistrate Judge Hixson 'disregarded' the parties' agreements and facts on the ground once again misconstrues the order. That Magistrate Judge Hixson did not find Sutskever's arguments persuasive does not suggest that he failed to consider them."
OpenAI and a representative for Sutskever declined to comment. Representatives for Musk did not immediately respond Monday to requests for comment.
Sutskever isn't the only OpenAI executive with whom Musk has been battling ahead of a March 2026 phase-one trial on his challenge to the company for-profit transition. Those fights were broken off from other parts of the case, like OpenAI's counterclaims accusing the world's richest person of a targeted "harassment" campaign.
Earlier in October, Judge Hixson allowed alternative service of a deposition subpoena on Mira Murati, OpenAI's former interim CEO, via FedEx, after Musk complained that the former OpenAI chief technology officer's security repeatedly "stonewalled" normal service.
Musk was an early funder of ChatGPT. In the suit filed last year, Musk accused OpenAI and CEO Sam Altman — Musk's former business partner — of setting the business' "founding agreement aflame" by moving to make the organization private. Musk said OpenAI was baiting and switching investors by allowing them to pour money into a technological innovation they believed would remain public.
Musk later brought in Microsoft, OpenAI's longtime partner and financial backer, as a defendant. Musk contended he was tricked into contributing $45 million with the false promise that OpenAI would remain a nonprofit.
OpenAI and Microsoft have sought to stop the first phase of nonprofit claims in their tracks, arguing they owe Musk nothing, in part because there was never a binding promise for OpenAI to remain a nonprofit.
