Musk’s third day on the stand put his own AI business and control ambitions under scrutiny, while the judge kept the case focused on OpenAI’s nonprofit obligations, Microsoft ties, and alleged enrichment—not existential-risk speeches.

Elon Musk sparred with lawyers…
- “It would be weird if Musk win this. They have proof that he tried to make OpenAI a part of his other companies.” — r/OpenAI (162 upvotes)
Our take: That’s the core tension for Musk: if the jury sees his own control efforts as evidence, his nonprofit-mission argument gets harder to sell. But proof that he wanted influence is not automatically proof against his charitable-trust claims, so the legal jump is bigger than Reddit makes it sound.
- “Just make your models open source and his lawsuit loses all basis... hes right you are open ai you should have remained that way.” — r/OpenAI (28 upvotes)
Our take: We get the moral symmetry, but open-sourcing the models would not magically erase claims about governance, enrichment, or past restructuring. Also, “open AI” has always been doing a lot of rhetorical work here; the court is deciding legal duties, not brand vibes.
- “Whoever loses will just appeal. Nothing will change for years.” — r/OpenAI (11 upvotes)
Our take: Probably right that appeals could drag this out, especially if the remedy is structural and not just money. But interim orders, injunctions, or even a narrow liability finding could still move markets and governance before the final appellate dust settles.

Elon Musk, the founder of xAI, has testified that his startup, now part of SpaceX, partially used OpenAI’s technology to train its artificial intelligence. This practice appears to violate the terms of service of OpenAI. Musk is seeking $134 billion in damages for…
- “So the Chinese companies running "distillation attacks" were actually Musk?” — r/artificial (16 upvotes)
Our take: The joke lands because the admission turns a favorite OpenAI complaint back onto its loudest critic. The legal significance depends on the facts and the terms, but as courtroom optics go, “my rival trained on your product” is not exactly clean-hands poetry.
