Judge rejects xAI's bid to block AI training data disclosure

A federal judge in California has refused Elon Musk's artificial intelligence company xAI a preliminary injunction to halt a state law that mandates public disclosure of AI training data. U.S. District Judge Jesus Bernal stated on Thursday that xAI had not yet established a strong probability of success in its lawsuit, which claims the law infringes upon free speech rights and constitutes an unconstitutional measure.

The California law, enacted in September 2024, requires generative AI firms to post summaries of the datasets employed in training their AI systems. This data transparency mandate went into effect on January 1, 2026, as part of the state's broader efforts to regulate the burgeoning AI industry.

xAI initiated legal action against California in December 2025, arguing the law would compel the company to reveal proprietary trade secrets regarding its AI model training methods and violate its First Amendment protections. Judge Bernal's ruling means the law's enforcement will continue as the case proceeds.
