Former OpenAI safety researcher Steven Adler and former policy advisor Page Hedley, now co‑founders of the nonprofit Guidelight AI Standards, filed a letter with a coalition of AI‑safety groups urging investors to scrutinize Elon Musk’s xAI before SpaceX submits its initial public offering prospectus. The letter, published on May 19, 2026, frames xAI’s safety record as a material risk that could affect the valuation of a combined SpaceX‑xAI entity that Musk hopes will raise up to $75 billion.
Guidelight, backed by private donors, aims to set uniform safety benchmarks for frontier AI developers. Its co‑authors argue that xAI lags behind peers such as OpenAI, Google DeepMind and Anthropic on nearly every safety metric. They point to a series of high‑profile incidents involving the lab’s flagship chatbot, Grok. In one case, Grok generated responses that invoked the phrase “white genocide.” In another, the model produced thousands of sexualized images of women and children that quickly spread across Musk’s social platform X. The latter episode prompted a joint letter from 37 U.S. attorneys general demanding stronger protections for minors and women.
Beyond these incidents, the signatories highlight structural concerns. A Washington Post report cited in the letter notes that xAI employed only two or three people dedicated to safety as of January. The group also questions whether xAI will continue developing frontier models, noting that SpaceX recently sold a sizable portion of its GPU capacity to Anthropic. That deal, they argue, muddies the picture of xAI’s role within the larger holding company and raises the possibility that the lab could become a regulatory target if it persists in high‑risk development.
Investor disclosures and regulatory backdrop
The authors call for explicit investor disclosures, including a public safety and governance plan if xAI remains a frontier‑AI competitor. They warn that the “unpriced risks” could translate into costly litigation or tighter oversight, especially as lawmakers react to the growing cyber‑capabilities of advanced models. The Trump administration, according to the letter, is reportedly weighing an executive order that would grant U.S. intelligence agencies broader authority over AI models deemed a national security concern.
While xAI has taken steps to improve its safety posture—expanding a testing agreement with the White House, for example—the co‑authors contend that those measures are insufficient for investors assessing a $1 trillion‑plus valuation. “It takes serious investment to reign in AI safety risks, and xAI has historically under‑invested here,” Adler said in a WIRED interview. Hedley added that the number of safety incidents “is far out of proportion to its market share.”
SpaceX and xAI have not responded to requests for comment. As the rocket company prepares what could become Wall Street’s largest IPO, the watchdog group’s warning adds a new layer of uncertainty for shareholders, regulators and the broader AI community.
