Elon Musk and Sam Altman are heading to court. A trial in Musk’s lawsuit against OpenAI kicks off in Oakland, California on April 27th, according to The Verge AI, and it’s about to drag every uncomfortable secret of the AI boom into public view.
The Verge AI reports that what looks like a fraud case is really something messier. Musk cofounded OpenAI, walked away when he didn’t get the CEO job, and has spent the last two years filing one lawsuit after another. He’s now on his fourth suit against the company. The first got pulled right before a major hearing. The current one survived after a racketeering claim got tossed. Two others targeted Apple’s ChatGPT deal and alleged employee poaching by xAI.
This is significant because of the timing. Musk’s xAI, now folded into SpaceX, has filed for an IPO. OpenAI is rumored to be eyeing one too. Billions are on the table, and the trial will pull receipts from inside both camps right when investors are sizing them up.
What Musk is actually claiming
In court, Musk’s team will argue three things:
- Altman and President Greg Brockman breached OpenAI’s charitable trust
- They unjustly enriched themselves at Musk’s expense
- They committed fraud by getting Musk to fund the nonprofit on terms they never honored
His demands aren’t small. He wants Altman and Brockman removed from their jobs, money paid to the OpenAI nonprofit, and the company forced to abandon its current public benefit corporation structure.
OpenAI’s response, as quoted in The Verge AI: this is a “blusterous campaign to harass OpenAI for his own competitive advantage.” The company argues Musk never got a “cognizable promise” that could ground a fraud claim, and points out he sat on his hands during OpenAI’s 2025 recapitalization when he could have formally objected.
The witness list reads like an AI industry yearbook
Expect testimony from Microsoft CEO Satya Nadella and CTO Kevin Scott. Former OpenAI cofounder Ilya Sutskever and former CTO Mira Murati may take the stand. The board members behind Altman’s brief 2023 ouster could be called too.
The filings have already produced a parade of leaked tech gossip. Excerpts from Brockman’s diary asking “What will take me to $1B?” Mark Zuckerberg texts about Meta teams being “on alert” to scrub content threatening DOGE staff. Musk calling Jeff Bezos “a bit of a tool.” None of this is central to the legal arguments. All of it is now part of the public record.
Why this matters for the AI industry
Legal experts quoted by The Verge AI aren’t kind to Musk’s odds. Loyola University of Chicago law professor Sam Brunson said the case “only ended up at trial because Elon Musk can pay his attorneys to argue a losing case.” Peter Molk at the University of Florida noted OpenAI has a self-help defense: Musk pulled promised funding, so the nonprofit had to find another way to survive.
But winning the legal argument and winning the reputational battle aren’t the same thing. Georgia Tech professor Deven Desai put it bluntly: trial documents and testimony “will make it harder and harder for OpenAI to keep claiming” it’s building safe AI for humanity’s benefit.
What stands out here is the broader pattern. Musk has turned litigation into a competitive weapon while xAI scales up to challenge OpenAI directly. Whether the jury buys his fraud theory or not, the discovery process is doing real damage to OpenAI’s nonprofit-origin narrative right as the company tries to lock in its for-profit transition.
What to watch next
Three things worth tracking over the coming weeks:
- Testimony from current and former OpenAI executives about what Altman and Brockman actually promised Musk in the early days
- Any new disclosures about OpenAI’s governance during the 2023 board crisis
- How Microsoft’s leadership handles questions about its OpenAI exposure on the stand
The trial runs in Oakland starting Monday. Full breakdown at the original source.
