Two former OpenAI employees and a group of AI safety nonprofits are warning that Elon Musk’s AI lab, xAI , could become a liability for prospective investors in SpaceX, which is preparing to file what’s expected to be the largest initial public offering in Wall Street History.
In a letter directed to investors published on Tuesday, the ex-staffers highlighted what they describe as “unpriced risks” related to xAI that could complicate SpaceX’s reported plans to raise up to $75 billion as part of its IPO. The rocket company’s private valuation shot up to over $1 trillion after it acquired xAI last year . Musk claimed his rocket company could launch data centers into space for his AI lab, but the letter's authors argue that xAI’s poor record on safety issues could complicate how investors view the combined company as it gets ready to submit its IPO prospectus filing .
One of the letter’s signatories and coauthors is a new nonprofit called Guidelight AI Standards, which was cofounded by former OpenAI safety researcher Steven Adler and former OpenAI policy advisor Page Hedley. The group, which is backed by private donors, aims to improve the safety practices of frontier AI companies. Other AI safety nonprofits also signed on, including Legal Advocates for Safe Science and Technology, Encode AI, and The Midas Project.
