What happened

Nine California jurors have begun deliberations in the trial between Elon Musk and OpenAI co-founders Sam Altman and Greg Brockman. The case examines whether the lab's leadership violated an agreement to use Musk's donations for charitable, non-profit purposes rather than for-profit commercialization.

What's new in this update

The jury is now deliberating on three specific charges: breach of charitable trust, unjust enrichment, and Microsoft’s role in aiding and abetting these actions. The deliberation follows trial testimony concerning the intent behind Musk's early financial support and whether a $10 billion investment from Microsoft in 2023 breached the organization's founding principles.

Key details

OpenAI's defense relies on the statute of limitations, arguing that any alleged harm occurred years before the 2024 filing. A forensic accountant testified that Musk's contributions were fully spent by August 2021, and witnesses, including Musk's own advisors, stated that no formal restrictions were placed on how those donations were utilized.

Background and context

The legal battle stems from Musk’s departure from OpenAI in 2018 and the organization's subsequent shift toward a capped-profit model. Musk alleges that the partnership with Microsoft finalized the abandonment of the lab’s original mission to develop artificial intelligence for the benefit of humanity, while OpenAI maintains that private fundraising was always necessary to achieve its safety goals.

What to watch next

If the jury finds in favor of Musk, a subsequent set of hearings starting next week will determine the remedies. These hearings will involve legal debate over whether OpenAI must return to a purely non-profit state or face other structural penalties, though a negative verdict would render these proceedings moot.

Why it matters

This trial determines if OpenAI’s multi-billion-dollar shift to a for-profit entity violated its founding mission and legal obligations to its early donors.
