Elon Musk Testifies in High-Stakes OpenAI Trial

Elon Musk testified in a federal courthouse in Oakland, California, on May 9, 2026 ^[1]. He took the stand in a significant legal battle against OpenAI CEO Sam Altman and co-founder Greg Brockman ^[1][3]. The lawsuit alleges the company betrayed its founding non-profit mission by pivoting toward a for-profit model after Musk provided early funding ^[1].

During his testimony, Musk addressed leadership complaints and the shift in the company's structure ^[2]. He argued that the transition into a for-profit enterprise violated the spirit of the original agreement ^[3]. The trial explores whether these corporate changes were legally permissible given the organization's initial mandates ^[1].

This legal decision could have major ramifications for the governance of artificial intelligence ^[1]. Industry experts suggest the verdict may redefine how AI development is managed globally ^[1].
