Sam Altman Testifies, Rejects Musk’s ‘Stealing a Charity’ Claim in OpenAI Trial

The testimony sets up an advisory jury decision next week that could reshape OpenAI’s leadership.

Overview

  • Altman, who took the stand Tuesday in Oakland, said the nonprofit-to-capped‑profit structure reflected the funding needed to build advanced AI rather than a scheme to divert a charity.
  • He testified that Elon Musk pushed for majority control early on, including a proposal for a 90% equity stake, which Altman said made him extremely uncomfortable.
  • Under cross‑examination, Altman faced questions about his honesty following earlier testimony from Ilya Sutskever, who told the court he spent about a year collecting examples of a “consistent pattern of lying.”
  • OpenAI chair Bret Taylor said an xAI‑led group sent a takeover proposal in February 2025, which he viewed as at odds with Musk’s stated goal of protecting a nonprofit mission.
  • An advisory jury is expected to weigh liability the week of May 18, after which Judge Yvonne Gonzalez Rogers will decide remedies that could include leadership changes or structural fixes affecting any IPO plans.
