Greg Brockman is on the stand, and OpenAI's founding mythology is getting cross-examined in a federal courtroom. Welcome to Musk v. Altman Daily — week two of trial, and the testimony is getting into the original promises that built this company. Week one gave us Musk saying he was duped, warning AI could kill us all, AND admitting xAI trained off OpenAI's models — that's a lot of ground to cover before lunch. All of it matters legally — we'll break down what Brockman's testimony means for Musk's core breach-of-contract claims, right after this. France24 sets up today's witness list:
Greg Brockman, co-founder and president of OpenAI, will face questioning from Musk's lawyers on Monday in the Oakland courthouse.
OpenAI CEO and co-founder Sam Altman, who in 10 years has gone from being Musk's protege to a bitter rival, is not expected to take the stand until the week of May 11.
The outcome of the case could shape the future of OpenAI, the fast-rising generative AI giant now valued at over $850 billion and preparing for an IPO.
Week two of Musk v. OpenAI, and this one's about Greg Brockman — co-founder, president, and the first OpenAI insider to face Musk's lawyers directly in that Oakland courtroom. And let's not lose the thread here — we're talking about an $850 billion company that started as a nonprofit. That's not a pivot, that's a magic trick. Musk's core argument is breach of that founding mission. His lawyers will try to use Brockman to establish what the original agreement actually was — and whether OpenAI walked away from it when the money got serious. Over on r/OpenAI, this one had 167 upvotes:
It would be weird if Musk win this. They have proof that he tried to make OpenAI a part of his other companies.
Right, so the guy suing to restore a nonprofit wanted to absorb it into his for-profit car company. That's the plot. And another r/OpenAI comment, with 28 upvotes:
Just make your models open source and his lawsuit loses all basis... hes right you are open ai you should have remained that way.
Someone's saying OpenAI should just open-source everything and the lawsuit evaporates — that's not how contract law works, but I get the frustration. Then there's the realist in r/OpenAI, with 12 upvotes:
Whoever loses will just appeal. Nothing will change for years.
And the realist take — whoever loses, appeals. This thing could drag past OpenAI's IPO entirely. Which means the real winner might just be the lawyers. Shocking development. Here's Hayden Field, on the evidence now surfacing:
The Musk v. Altman trial is underway, and that means exhibits, or the evidence to be presented in court, are being revealed piece by piece. So far, email exchanges, photos, and corporate documents are circulating from the earliest days of OpenAI — and from before the AI lab even had a name.
The Verge's Hayden Field and Adi Robertson have been tracking the trial exhibits as they drop — emails going back to 2015, before OpenAI even had a name. The picture emerging is of Musk as a genuine founding architect: he largely drafted the mission, shaped the early structure, and was clearly angling for control. Jensen Huang just handed them a supercomputer. Like, 'here's a billion dollars of hardware, good luck.' That detail alone tells you how much early hype was carrying this thing before a single product shipped. What's legally interesting is that Brockman and Sutskever were apparently documenting concerns about Musk's control level in real time — that's contemporaneous evidence, and that's the kind of thing that's hard to explain away on the stand. So the people inside OpenAI were worried Musk had too much power... and now Musk is in court arguing he didn't have enough? I'm not saying he's wrong on the law, but the irony is doing laps. CNBC has the setup from Musk's testimony: Day two of Musk v. Altman, and Elon took the stand himself — testifying that OpenAI was founded as a nonprofit specifically to counter Google's dominance in AI. That's the core of his legal argument: that the mission was baked in from the start, and the for-profit conversion betrays it. And now he's suing the company he helped build while running his own AI company. I'm not saying the argument is wrong — honestly, a nonprofit counterweight to Google sounds exactly like what we need — but Elon Musk is not exactly a disinterested witness here. That's fair, and the defense will absolutely go after his credibility on that point. But legally, his motivations don't invalidate the claim — what matters is whether there was a binding charitable commitment that OpenAI is now breaking. And Michelle Kim at MIT Technology Review puts the stakes this way:
Musk is asking the court to remove Altman and Brockman from their roles and to unwind the restructuring that allowed OpenAI to operate a for-profit subsidiary. The outcome of the trial could upend OpenAI’s race toward an IPO at a valuation approaching $1 trillion.
Week one of Musk versus Altman is in the books, and MIT Technology Review has the rundown. Musk took the stand in Oakland, told the jury he was a fool who handed OpenAI thirty-eight million dollars of free funding, and then sat through the revelation that his own company, xAI, has been distilling OpenAI's models to train Grok. So he's suing OpenAI for going commercial while quietly using their models as a cheat code for his own for-profit AI. That is a bold posture to take in a federal courthouse. Bold, yes — but legally, the distillation admission could cut both ways. It may actually bolster OpenAI's counterclaims more than it helps Musk's fraud narrative. And then he drops the 'AI could kill us all' warning on the jury? I genuinely don't know if that's a legal strategy or just Elon being Elon, but I need to know which one.
