"By the end of this week, you and Sam will be the most hated people in America" — Musk's message sent the day before trial
The Musk v. OpenAI trial now underway in Oakland Superior Court enters its second week. Greg Brockman, OpenAI's co-founder and President, takes the stand May 5 (local time). OpenAI CEO Sam Altman is scheduled to testify the week of May 11.
This is far more than a personal dispute between two men. The outcome will determine the future of OpenAI, which has surpassed an $850 billion valuation and is preparing for an IPO.
Musk's Message the Day Before Trial
A filing submitted to the judge by OpenAI's legal team Sunday evening revealed a striking detail. Shortly after settlement negotiations broke down outside court the day before trial, Musk sent a text message to Brockman. The message read: "By the end of this week, you and Sam will be the most hated people in America. If you insist on this course, that's what will happen."
OpenAI requested permission to present this message to jurors as evidence that Musk engaged in improper pressure tactics outside the courtroom.
What Musk Is Seeking
Musk contends that OpenAI must revert to a non-profit structure. He testified that he donated $38 million to OpenAI from 2016 to 2020 and played a key role on the board until his removal.
Musk's argument is straightforward: "You cannot simply steal a charitable organization." OpenAI was founded with a promise to be a non-profit AI research institute for humanity's benefit—and Musk donated based on that pledge. Yet today, OpenAI is receiving tens of billions in investment from Microsoft and operating as a for-profit entity worth $850 billion. This, Musk argues, is a breach of contract.
Microsoft (MSFT) is also a central defendant. It faces allegations of unlawfully funding OpenAI's commercial conversion, and CEO Satya Nadella may testify this week.
OpenAI's Defense
OpenAI's legal team challenges Musk's financial motives. Musk founded rival AI company xAI (which operates the Grok chatbot). Recently, he merged xAI into SpaceX, which is also preparing for an IPO. Weakening OpenAI directly serves Musk's competitive and financial interests, the argument goes.
OpenAI maintains its current structure is a for-profit entity but remains under a non-profit parent. This is not a complete abandonment of the non-profit model, the company argues.
Verdict's Impact on OpenAI's IPO
If Judge Yvonne Gonzalez Rogers rules in Musk's favor, OpenAI's IPO faces serious jeopardy. An order to convert to non-profit status would undermine the entire $850 billion public offering plan.
The trial touches on the global race for AI dominance. If OpenAI stumbles, Google, Chinese AI firms, and Anthropic could gain relative advantage. That's why dozens of reporters pack the courtroom daily.
Frequently Asked Questions
What happens to OpenAI if Musk wins the trial?
If the judge orders conversion to non-profit status, OpenAI cannot maintain its for-profit structure that distributes returns to investors including Microsoft. The IPO would be halted or require major restructuring.
Why is Microsoft a defendant in this case?
Musk argues Microsoft is jointly responsible for undermining OpenAI's non-profit mission by funding its commercial conversion. Microsoft has invested tens of billions of dollars in OpenAI.
What does it mean for OpenAI to be non-profit?
It's not fully non-profit. There is a for-profit subsidiary where investors expect returns, but a non-profit parent entity oversees it with a mandate to serve "AI for humanity." Musk claims this structure has become meaningless.
What does this trial mean for international investors?
Short-term: potential Microsoft (MSFT) stock impact. Medium-term: IPO timing/structure could affect OpenAI private exposure vehicles. If OpenAI weakens, Google (GOOGL) and Anthropic could gain relative advantage in AI competition.
