It happened. Kind of a nothingburger, as Brockman said that the deal was “not really my focus area.” We are now back in his disclosures. OpenAI did a December 2025 deal with Cerebras, for $10 billion of chips — and Brockman had an investment. The deal increased Cerebras’ valuation to $23 billion. “Your equity in Cerebras became more valuable because of the transaction OpenAI did?” Brockman admits that’s possible.
But Brockman is back on the stand, and boy, morning has not been good to him. We are now moving on to Microsoft.
You may recall from Musk’s testimony that OpenAI has used purple boxes to highlight things. We see another purple box in OpenAI LLC’s announcement it exists. Molo asks if this is something OpenAI generally uses in its paperwork to highlight important things. Brockman says no. We go back and forth on this for a while, because Brockman thinks Molo’s statement is overly broad.
Brockman is worth $30 billion. Molo has been asking, over and over, why Brockman hasn’t donated the $29 billion to OpenAI’s charity since he’d be good at $1 billion. Brockman has been making weird non-answers. He sounds nervous and not especially convincing.
The famous Brockman quote has finally hit. Molo is arguing that rather than figuring out funding for the nonprofit, Brockman was plotting to get rich. Brockman is trying to say that there’s more context. While Molo is getting worked up, Brockman is pretty level. “Do we accept Elon’s terms, or do we reject the terms, he quits to create his own [AI company], and then we create our own [AI company]?” Molo tried to strike the answer, but he is overruled.
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.
