Musk’s OpenAI Testimony Falters, Citing Charity Theft and $800 Billion Plan

Musk took the stand for the third day in a four‑week trial over his lawsuit that seeks to block OpenAI’s planned public listing. The case hinges on whether OpenAI abandoned its original nonprofit mission. Musk’s goal is to keep the organization nonprofit and, if successful, to force the removal of CEO Sam Altman.

During cross‑examination, Musk claimed OpenAI’s leadership “stole a charity” after the group accepted $38 million in donations. He added that he was tricked into providing “free funding” for a nonprofit that Altman allegedly plans to convert into an $800 billion enterprise. The figure reflects Altman’s projected market value if the company goes public later this year.

Musk also asserted that he never loses his temper, yet he raised his voice at OpenAI’s lawyer when pressed on details. The lawyer later produced documents that contradicted Musk’s statements, highlighting inconsistencies in his account.

The testimony came after Musk’s lawyers failed to keep his ties to former President Donald Trump off the record, prompting the judge to consider additional evidence that could further undermine Musk’s credibility.

OpenAI, backed by Microsoft, argues that Musk’s lawsuit is a tactical move to slow its competitor while his own AI venture, xAI, lags behind. The company maintains that Altman’s vision remains focused on advancing artificial intelligence for humanity, not personal enrichment.

If the judge rules against Musk, OpenAI could proceed with its IPO slated for the fourth quarter of 2026, potentially valuing the firm at $800 billion. A ruling in Musk’s favor would preserve the nonprofit status and keep Altman’s leadership under scrutiny.

What to watch next: The judge’s decision on whether to admit further evidence about Musk’s political connections and the upcoming closing arguments that could tip the balance toward or away from an OpenAI IPO.
