CoinEx News: Elon Musk took the stand in federal court in Oakland on April 28, 2026, as opening statements began in his civil trial against Sam Altman, OpenAI, Greg Brockman and Microsoft. Musk alleges OpenAI abandoned its nonprofit mission through its for-profit transition and is seeking about $150 billion in damages for OpenAI's charitable arm, while Bloomberg reported on March 31 that OpenAI completed a $122 billion round at an $852 billion valuation.

The case keeps AI governance, mega-round valuations and public-benefit structures in focus, leaving AI-linked risk appetite sensitive to courtroom disclosures and any pressure on OpenAI's corporate restructuring.
