X owner Elon Musk vowed to appeal a federal grand jury’s verdict against his claim that OpenAI CEO Sam Altman was abandoning the company’s original nonprofit vision after it ruled it was not brought in a timely manner.

Musk said the jury did not rule on the evidence of the case, but rather a “calendar technicality,” and reiterated his claims that Altman transitioned OpenAI from a charity model to a for-profit business.
