Elon Musk testified for three days this week in his lawsuit against OpenAI, with court documents revealing emails, texts, and tweets that expose deep rifts between the parties. Musk's core claim centers on betrayal. He argues that Sam Altman violated OpenAI's original nonprofit mission by converting the company into a for-profit entity. The litigation is still in early stages, with multiple witnesses lined up to testify. The case hinges on whether Altman's structural pivot constitutes fraud or breach of contract regarding the company's founding principles. Both sides have submitted substantial documentation. The lawsuit represents one of tech's biggest internal power struggles, pitting Musk, who co-founded OpenAI in 2015, against Altman, who now leads the company valued at $157 billion after its latest funding round. The trial will likely reveal details about OpenAI's governance decisions, investor pressure, and strategic pivots that shaped the AI race. More testimony and evidence will follow in coming weeks.
