Elon Musk is suing OpenAI and Sam Altman again

Elon Musk is back in court with OpenAI, just two months after mysteriously dropping his first case.

On Monday, Musk filed a new lawsuit in Northern California federal court against OpenAI, CEO Sam Altman, and cofounder Greg Brockman, claiming they abandoned the startup's original mission to develop AI for the benefit of humanity.

From breach of contract to a "long con"

Musk's previous suit, which focused on keeping OpenAI's technology open source, was quietly withdrawn in June without explanation. His lawyer, Marc Toberoff, told The New York Times that this new filing is a much more forceful lawsuit.

The complaint alleges that Altman and Brockman assiduously manipulated Musk into co-founding the venture, calling the assurances about its non-profit structure the hook for Altman's long con.

Musk is now invoking federal racketeering laws, alleging a conspiracy to defraud. The suit also takes aim at OpenAI's partnership with Microsoft and the definition of artificial general intelligence (AGI), arguing that Microsoft's rights to the technology should be revoked once AGI is reached.

Why it matters

This is no longer just a billionaire grudge match; it directly challenges OpenAI's commercial structure.

We think targeting the definition of AGI and the Microsoft deal is a calculated move. If a court scrutinizes whether OpenAI has already achieved AGI or questions the shift away from its non-profit roots, the legal cloud over its most critical backer could create serious turbulence.

Racketeering claims are notoriously difficult to prove in corporate disputes. But Musk may not need an outright legal victory; the discovery process alone could force OpenAI to air guarded partnership details and internal roadmaps.
