A U.S. federal judge dismissed Elon Musk's fraud claims in his lawsuit against OpenAI and Sam Altman, although the core of the case remains. The trial will focus on the remaining allegations of breach of charitable trust and unjust enrichment. Musk seeks up to $134 billion in damages, claiming OpenAI abandoned its original nonprofit mission. OpenAI restructured to include a for-profit subsidiary, leading to a surge in valuation. Musk, a co-founder of OpenAI, alleges he was deceived regarding the company's direction. The relationship between Musk and Altman deteriorated after disagreements over OpenAI's goals. Musk launched a competing AI venture, xAI, which merged with X. The lawsuit involves claims of unjust enrichment and breach of charitable trust. Musk's team dropped the fraud claims to streamline the case. The court proceedings will be divided into liability and remedies phases. The jury will decide on any wrongdoing, while the judge will determine damages. Key figures like Musk, Altman, and Microsoft's CEO are expected to testify. The trial is expected to continue through mid-May, with a possible remedies phase starting on May 18th. Jury selection is underway in Oakland, California.
