The initial investment was $38 million. The shared vision was grand, even delusional. Now, in a San Francisco federal courtroom, the man who signed that check is testifying about the rupture.

Elon Musk is suing OpenAI, the company he helped create. He has filed three other suits against it. This is the first to reach a jury.

The three were on the initial founding team of OpenAI, with Musk investing up to $38 million early on before the co-founders' relationship soured over disagreements over company structure and mission, including whether or not OpenAI should be folded into Musk-owned Tesla. Musk walked away and, years later, founded xAI -- his own direct competitor to OpenAI, which is now owned by Musk's SpaceX. In recent years, Musk has filed no less than four different lawsuits against OpenAI, many of which have since been dropped or dismissed. This one, though, names Altman, Brockman, Microsoft, and OpenAI itself as plaintiffs, and it has made it to jury trial in a California federal courtroom.

Musk’s legal claim hinges on a breached nonprofit mission. He argues the pursuit of profit with Microsoft corrupted OpenAI's goal to benefit humanity. The deeper grievance is more straightforward.

He wanted OpenAI inside Tesla. Sam Altman refused. The departure, the founding of rival xAI, the barrage of lawsuits—it’s all a protracted campaign for control.

That first $38 million was merely the opening bet. The trial is the latest maneuver in Musk's relentless effort to rewrite the story.
