The man building an AI company to compete with OpenAI just spent three hours on a witness stand explaining why he's entitled to $150 billion from OpenAI.
The Summary
- Elon Musk testified for nearly three hours in his $150 billion lawsuit against OpenAI, claiming Sam Altman turned a nonprofit AI lab into "one of the greatest heists in history"
- OpenAI's defense argues Musk was the real capitalist, who left when other founders wouldn't follow his plans for control
- Musk waited six years to sue, claiming he only reacted when Microsoft invested $10 billion in fall 2022 and "the tail started wagging the dog"
- A nine-member jury will decide if OpenAI, now valued at $730 billion, must unwind its for-profit structure in what could be a monthlong trial
The Signal
The OpenAI trial is a cage match between two competing origin stories of the agent economy. Musk's version: he funded a nonprofit to save humanity from AI risk, then watched Sam Altman stage a corporate heist. OpenAI's version: Musk wanted total control, couldn't get it, and rage-quit to build a competitor.
The trial exposes the fundamental tension at the heart of Web4. How do you fund AGI development without becoming the thing you said you'd prevent? Musk told the court he had no problem with OpenAI creating a for-profit subsidiary, as long as it served the nonprofit mission. His problem: "the tail is wagging the dog." Microsoft's $10 billion investment in 2022 was the trigger. Before that, OpenAI was a research lab burning Musk's money. After, it was a $730 billion company printing revenue from ChatGPT subscriptions and enterprise contracts.
"This lawsuit is very simple: It is not OK to steal a charity."
The timing matters. Musk left OpenAI in 2018. He sued in 2024. That six-year gap is the entire case in miniature. Under cross-examination, Musk explained he only realized the for-profit had overtaken the nonprofit mission after Microsoft's investment. OpenAI's lawyers will hammer this. If it was a heist, why did it take you six years to notice? The obvious answer, which they won't say but everyone knows: Musk didn't care until OpenAI became more valuable than xAI.
Here's what makes this more than Valley gossip. The jury's decision could force OpenAI to unwind its for-profit structure. Imagine $730 billion in market cap reorganized as a nonprofit. Judge Yvonne Gonzalez Rogers seated nine jurors who will hear from tech moguls, former board members, and early employees over the next month. They're not tech lawyers. They're normal people trying to parse emails between billionaires about whose AI company gets to save or destroy the world.
The exhibits tell their own story. Documents show Musk once positioned himself as a potential OpenAI CEO. OpenAI will use this to paint Musk as power-hungry, not principle-driven. Musk will argue it proves he was committed. Both can be true. The early days of transformative companies are always messy. Everyone involved rewrites their own role once the outcome is clear.
The Implication
Watch how this trial shapes the next wave of AI funding. If Musk wins, every AI lab will think twice before spinning up a for-profit arm. If OpenAI wins, the playbook is set: start as a nonprofit for the halo, pivot to for-profit for the scale, dare anyone to stop you six years later.
For anyone building in the agent economy, the lesson is simpler. Structure matters at the start. Put the governance terms in writing. Don't rely on shared mission to prevent fights when the asset becomes valuable. Musk and Altman both bet billions on AI alignment. They just can't align on who gets to own the company doing the aligning.
