Greg Brockman’s journal really is making Greg Brockman look unreliable. Six days after telling Musk that Brockman et al. wanted more results in the nonprofit and to fundraise there, he writes, “We’ve been thinking about that maybe we should just flip to a for-profit. making money for us sounds great and all.” Brockman says this was an expression of a frustration and not a plan. Molo asks if he rehearsed that. Brockman says “no.”

He also writes, “To convert to a b-corp without him. That’d be pretty morally bankrupt.” That’s probably the most solid thing the Musk team has gotten out during the trial so far.
Molo asks if the nonprofit should still be a philanthropic endeavor. Brockman says, forcefully, “no.” We then look at notes from his diary, where he records Musk as saying “gotta figure out how do we transition from non-profit or something which is essentially philanthropic endeavor and is b-corp or c-corp.” Does make Brockman look pretty shifty.
We are hearing a lot of “I wouldn’t characterize it that way,” “I’m not sure I’d say it that way,” and “This sounds like something that I wrote, is it okay if we see it in context?” It’s not as contentious or tense as Musk’s exchanges with Savitt, but it’s definitely notable.
The question is whether Brockman disclosed his ownership of Cerebras when OpenAI was discussing merging with it. Brockman told Teller and Zilis, who were in theory Musk’s chiefs of staff, but not Musk himself. Molo is driving this home, which… I am less convinced by. Lots of executives delegate.
Musk’s team is finally landing some serious blows — namely that part of Brockman’s compensation was a grant from Altman’s family office. Musk’s adviser Jared Birchall wrote, “Greg is going to have a greater allegiance toward Sam as a result of this arrangement.” Brockman told Musk that “We ran out of YC stock fulfilling others’ offers” so Altman arranged the deal.
Molo is saying it’s a “side deal” that Musk wasn’t informed about. Except the email chain plainly says Altman informed Birchall directly, who then emailed Musk. I imagine that will come on direct. Still, the financial conflict of interest is the most undermining information I’ve seen from Musk’s team so far.
At a dinner about AI that Brockman and Altman attended, Musk was late. The first thing Brockman remembers Musk asking is, “Is Demis Hassabis evil?” Hassabis, of course, ran DeepMind.
It was initially supposed to be part of Y Combinator, as a research arm. Looking at a solicitation email from Brockman to then-CEO of Yahoo Marissa Mayer, Brockman writes that donors include Elon Musk, Jessica Livingston, Reid Hoffman, and Peter Thiel. “I’m personally donating $100,000,” he writes. But he didn’t end up donating that. Brockman is speaking very quickly and very softly, and YGR has just scolded him for it.
Brockman is taking the stand next.
I still don’t really understand how this expert helps Musk’s case, if at all.
We are now going through previous statements that Russell has made about Musk — for instance, Russell says that the “age of abundance” Musk talks about with AI robots will be great for Musk because of his pay package with Tesla. Also that Russell would not recommend that Musk be an AI adviser for President Trump.
The expert has testified in front of the US Senate about the dangers of open-sourcing AI systems. “If we open-source AI systems that are unsafe, we dramatically increase the risks,” Russell says. One of Musk’s contentions is that OpenAI is betraying its mission by not open-sourcing its models. Russell is now saying, in response to cross-examination, that open-sourcing can make it easier to remove safety guardrails that have been put in place. “It requires additional and very stringent safety measures.”
I really have no idea what it adds to Musk’s case. It seems to just be a way of running out the clock — but why bother? Is it just a way of giving OpenAI less time to defend themselves?
It’s very boring. Mainly we are establishing that the expert witness provided no specific opinions on OpenAI’s safety.
Because otherwise, this would be the guy to ask about the nonconsensual undressing and MechaHitler. We are getting slowly to the point, I think — which is that Russell suggests safety concerns would slow AI development. “Each company individually feels it needs to be in this race,” he says. “That means they can’t stop and solve the safety problem, which I think some of their employees would like to do, but the overall company police is preventing them.”
His name is Stuart Russell, and he’s getting $4,000/hr for his first 40 hours of working with the team (and $1,500/hr after that). Seems like an expensive way for Musk’s lawyers to run out the clock… Because while we are getting some testimony about AI risks, I don’t really understand how this is relevant to the dispute at hand.
We’re going through motions before the jury arrives. The motion I highlighted earlier this morning has been denied; YGR says the time to bring in the threats from Musk was when Musk was on the stand.
In response, Greg Brockman suggested both OpenAI and Musk drop their claims. Musk wasn’t interested. “By the end of this week, you and Sam [Altman] will be the most hated men in America,” he told them. OpenAI’s lawyers are trying to get the statement admitted to court as evidence that “Mr. Musk’s motivation in pursuing this lawsuit is to attack a competitor and its principals.”

In addition to our ongoing reporting from the courtroom and digging through newly released evidence, you will be able to listen in live via YouTube. While recording or rebroadcasting the stream is prohibited, we can expect it to be live generally between 11AM and 5PM ET while court is in session.
For now, though, Hayden Field can catch you up on all the evidence released.
No courtroom updates today, but we have updated our rundown of the evidence with the latest exhibits added in Elon v. Musk, including details of the donated Tesla Model 3s.

It’s dangerous to tell a courtroom ‘I don’t lose my temper.’
The federal judge overseeing the case granted Musk’s request on Friday, which he says will “streamline the case” and keep things focused on “ensuring that OpenAI adheres to its public charitable mission.” Two claims will proceed to trial this week.
A report by Bloomberg points out that the DOJ has joined an xAI lawsuit against the Consumer Protections for Artificial Intelligence law that is set to take effect in Colorado on June 30th. In their filing, the government’s lawyers claim that by requiring developers to take “reasonable care to protect consumers” from algorithmic discrimination, the law violates the Equal Protection Clause of the Constitution.

The space / AI / social network company is working with Intel to build its “Terafab” chip plant that Musk said could rely on a new 14A chip manufacturing process.


The NAACP is suing xAI to block Elon Musk’s Colossus 2 data center project outside of Memphis, TN, claiming that the project is operating 27 gas turbines without an air permit and in violation of the Clean Air Act.
“By looking to evade clear air laws to operate dirty turbines that emit pollution and known carcinogens, these companies are following a shameful, familiar pattern: asking Black and frontline communities to bear the toxic brunt of ‘innovation,” said Abre’ Conner, NAACP Director of Environmental and Climate Justice.
Anthropic’s shared, agentic AI workspace for macOS and Windows is getting much-needed tools for IT admins to do company-wide deployments, letting anyone build and deploy autonomous workflows so long as their organization is on a paid plan. It now adds the ability to turn Zoom meeting transcripts into action items.
Kozic will focus on infrastructure at the well-funded startup, which Bezos leads with former Google exec Vikram Bajaj, according to the FT. Project Prometheus is focused on using AI to improve manufacturing. Kozic’s defection is the latest in a broader wave of AI talent reshuffling.
