Both sides make their final case in an Oakland courtroom over broken promises, billions in dispute, and the future direction of artificial intelligence.
Estimated read time: 8 – 12 minutes
The world’s most consequential tech trial didn’t happen in Silicon Valley. It happened in Oakland — across the bay, a few miles from the gleaming campuses and infinite kombucha taps — in a federal courtroom where lawyers in suits argued over emails, broken promises, and who really gets to own the future of humanity.
On Thursday, closing arguments wrapped in the landmark civil trial of Musk v. Altman, and if you weren’t paying attention, you should have been. Because what’s playing out inside that courtroom isn’t just a billionaire grudge match. It’s a full-scale reckoning over what artificial intelligence is actually for — and who it’s actually serving.
Spoiler: it might not be you.
How We Got Here: A Friendship Gone Nuclear
Let’s rewind. It’s 2015. Elon Musk — then still largely regarded as the real-life Tony Stark rather than a chaos agent with a social media platform — sits down with Sam Altman and a handful of idealistic researchers to co-found something genuinely unusual: a nonprofit AI lab called OpenAI. No shareholders. No quarterly earnings calls. No IPO dreams. The pitch was almost radical in its simplicity — build the most powerful AI in human history, but do it for everyone, not for profit.
Musk poured $38 million into that vision. He believed in it. Or at least, that’s what he says now.
By 2018, he was gone — pushed out, according to some accounts, or walked out in frustration, depending on who you ask. And while he was busy launching rockets and buying social networks, the people he left behind were quietly doing something he apparently didn’t sign off on: turning OpenAI into a money machine.
Fast-forward to 2024: ChatGPT is a global phenomenon, OpenAI is valued in the hundreds of billions, Microsoft has become its biggest financial backer, and Musk files a lawsuit accusing Sam Altman and co-founder Greg Brockman of betraying the nonprofit mission he says they all shook hands on. No contract. No signed charter. Just — he claims — a shared moral understanding. A promise. A trust.
Now a jury of regular people has to decide if that trust was real, and if breaking it has a dollar amount.
“Five People Called Him a Liar. Under Oath.”
Musk’s attorney, Steven Molo, didn’t come to Oakland to play nice. His closing argument was a surgical strike aimed directly at the one thing OpenAI’s defense cannot afford to lose: Sam Altman’s credibility.
“I confronted Sam Altman with the fact that five witnesses in this trial — all people that he’s known for years, worked with for years — called him a liar under oath,” Molo told jurors. “Liar’s a very powerful word in a courtroom.”
Those five weren’t random critics pulled from Reddit threads. They were insiders: Musk himself, Ilya Sutskever (OpenAI’s former chief scientist and one of the most respected AI researchers on the planet), Mira Murati (OpenAI’s ex-Chief Technology Officer), and two former board members, Helen Toner and Tasha McCauley — the same board members who briefly fired Altman in 2023 before a staff revolt forced his reinstatement.
Molo’s argument was blunt and strategic: you don’t need a signed contract if you can prove a charitable trust existed through conduct, communication, and consistent public representations. Emails, website language, press interviews, public statements — Musk’s team argued all of it, stitched together, constitutes a binding charitable commitment that OpenAI then shredded the moment real money came into view.
“Sam Altman’s credibility is directly at issue in this case,” Molo said. “The defendants absolutely need you to believe Sam Altman. If you cannot trust him, they cannot win. It’s that simple.”
It was a clean, almost elegant argument — right up until the judge intervened.
A Courtroom Collision — and a Judge Who Wasn’t Having It
In what may be the trial’s most quietly dramatic moment, U.S. District Judge Yvonne Gonzalez Rogers called out Musk’s own attorney in a sharp, unambiguous rebuke.
While jurors were out of the room, Molo had suggested to the jury that Musk wasn’t seeking any money. The judge didn’t let that slide.
Musk, she pointed out, is seeking billions — not for himself personally, but in the form of “disgorgement” that would flow to OpenAI’s charitable arm. She ordered Molo to either retract the statement or formally drop the billion-dollar claim.
It was a reminder that even in a trial this large, the mechanics of a courtroom still apply — and that optics can be weaponized by both sides. Musk’s team has tried to frame him as a principled idealist fighting for a noble cause. The judge’s intervention briefly cracked that frame.
OpenAI Fires Back: “He Wanted Total Control”
Sarah Eddy, OpenAI’s attorney, took a different approach. She didn’t try to rehabilitate Altman’s image so much as redirect the jury’s attention toward Musk’s own motivations — and they aren’t flattering.
“Mr. Musk has tried to persuade you that his years-ago donations to OpenAI came with specific strings attached — strings strong enough to last forever, to tie OpenAI up in knots as it tries to pursue its mission, and that these strings gave Mr. Musk perpetual rights over OpenAI,” she said. “But Mr. Musk has come nowhere close to making that case.”
Then came the gut-punch: Eddy referenced trial testimony that Musk had discussed the possibility of his children inheriting control of OpenAI.
“He wanted dominion over AGI,” she said. AGI — artificial general intelligence — is the industry’s term for AI that matches or surpasses human intelligence across all domains. It is, depending on who you ask, either humanity’s greatest achievement waiting to happen or an existential threat we’re building on a deadline.
“Mr. Musk wanted total control,” Eddy continued. “Maybe, maybe he’d give it up over time. Or maybe not. But it was up to him — and that was the problem.”
It’s a devastating framing if the jury buys it. Because it transforms the entire lawsuit from a whistleblower exposé into something far more cynical: a powerful man who lost his grip on a powerful technology and wants it back — dressed up in the language of altruism.
The Timing Problem That Could End Everything Before It Begins
Here’s the legal wrinkle that most coverage has buried beneath the drama: this entire case might not even get decided on its merits.
The jury’s very first task is to determine whether Musk filed his lawsuit in time. OpenAI has argued that the statute of limitations bars Musk from claiming harms that occurred before August 2021 — and given that the core of his complaint concerns decisions made during OpenAI’s early years, that’s a potentially fatal problem for his case.
Judge Gonzalez Rogers herself wrote in a court filing that “if the jury finds that Musk failed to file his action within the statute of limitations, it is highly likely” that she will accept that finding and direct a verdict in favor of the defendants.
In plain English: if the jury decides Musk waited too long to sue, the whole thing is over — no discussion of charitable trusts, no billions in disgorgement, no Altman ouster. Just a procedural death and a quiet walk out of the courthouse.
For all the high theater of closing arguments, the most consequential question might be the most boring-sounding one.
What’s Actually at Stake — and Why It Matters to Everyone Who Isn’t a Billionaire
Strip away the personalities and the courtroom drama and the protest signs outside, and what you’re left with is this: a trial that will help define whether the most powerful technology in human history can be built, controlled, and profited from with zero accountability to the public that stands to be most affected by it.
OpenAI, Musk’s own AI company xAI, and Anthropic — a firm founded by seven former OpenAI employees — are all barreling toward initial public offerings expected to be among the largest in history. If Musk wins, OpenAI’s IPO could be derailed or restructured. If he loses, the message to the industry is equally clear: nonprofits can become for-profits, founders can be squeezed out, and as long as you’re fast enough, aggressive enough, and lawyered up enough, there’s no promise that can’t eventually be unwound.
Neither outcome is particularly comforting if you’re one of the millions of people whose jobs, healthcare information, or creative work is being fed into these systems right now.
Outside the Courthouse: The View From Everyone Else
While the lawyers made their final arguments inside, a different kind of argument was happening on the courthouse steps.
More than a dozen protesters gathered outside — not to support Musk, not to defend Altman, but to say loudly that the whole spectacle was a fight between two billionaires over who gets to control something that should belong to no one and everyone simultaneously.
Signs read: “Stop replacing healthcare workers with chatbots!” and “No future for workers in the Musk-Altman world.”
“We’re all losing,” said Saru Jayaraman, a labor activist who has been pushing for a $30 minimum wage on state ballots. “Who’s really winning? The two of them.”
Phoebe Thomas Sorgen, a peace activist from Berkeley, went further: “Both parties in this trial are completely hypocritical. They both claim they’re developing AI for the benefit of humanity. That’s a lie. They’re developing it for greed.”
It’s easy to dismiss protesters on courthouse steps as noise. But in this case, they may be making the most intellectually honest argument of anyone in the building. The question of who benefits from AI — really benefits, not in the PR-approved talking-points sense — is not being adjudicated inside that courtroom. The jury isn’t being asked to weigh in on job displacement, algorithmic bias, or the concentration of world-altering power in the hands of a tiny number of unelected people.
They’re being asked to decide if one very rich man made a promise to another very rich man — and whether breaking it was illegal.
What Comes Next
The jury is now deliberating. A verdict could arrive in days or drag into weeks.
If Musk wins: OpenAI faces potential structural upheaval, Altman could be removed from leadership, and the company’s IPO — and the narrative around it — gets dramatically complicated.
If OpenAI wins: Musk walks away with nothing except a legal bill, a bruised reputation, and possibly a sharper sense of what “I should have gotten that in writing” actually means.
Either way, the AI industry doesn’t pause. The models keep training. The chips keep running. The money keeps moving.
And somewhere between the closing arguments and the jury instructions, a question nobody in that courtroom seemed particularly interested in answering hangs in the air like smoke:
Who gave any of them permission to build this in the first place?
