SpaceX Claims It’s Building One of the Galaxy’s Most Advanced Civilizations—Experts Aren’t Convinced
In a move that has drawn both awe and skepticism, SpaceX has made an extraordinary claim as it prepares for its initial public offering: that it is helping forge one of the most advanced civilizations in the Milky Way. The assertion, embedded in the company’s S-1 filing with the U.S. Securities and Exchange Commission, has raised eyebrows among space scholars who say it stretches both scientific credibility and regulatory norms.
Elon Musk, the company’s founder and chief engineer, first floated the idea in a signed mission statement published on SpaceX’s website just before the IPO application. “SpaceX has acquired xAI to form the most ambitious … innovation engine on (and off) Earth,” he wrote, citing a fusion of artificial intelligence, rockets, space-based internet, direct-to-mobile communications, and what he called “the world’s foremost real-time information and free speech platform.”
Musk went further, outlining a vision to launch a mega-constellation of a million satellites operating as orbital data centers. “That is a first step towards becoming a Kardashev II-level civilization,” he said, “one that can harness the Sun’s full power, while supporting AI-driven applications for billions of people today and ensuring humanity’s multi-planetary future.”
The Kardashev scale, developed by Soviet astronomer Nikolai Kardashev in the 1960s, ranks civilizations by their energy consumption. A Type I civilization harnesses all the energy available on its home planet; Type II captures the full output of its star; Type III commands the energy of an entire galaxy. Earth, by most estimates, has not yet reached Type I—astronomers like Carl Sagan pegged humanity at roughly 0.73 on that scale.
Brian Hurley, founder of the influential New Space Economy think tank and a leading space sector scholar, says Musk’s claim finds no support among astrophysicists who use the Kardashev system to search for extraterrestrial techno-signatures. “A Type II civilization is associated with harnessing the energy output of its star,” Hurley told me. “A million satellites, even extremely large orbital data centers, would still be many orders of magnitude below that standard.”
Hurley notes that the claim, repeated in the SEC filing, could present a regulatory headache. “The SEC is unlikely to referee astrophysics or speculative futurism directly,” he said. “But the real question is whether it is material, supportable, and potentially misleading in the context of the offering.” He added that he would be “disappointed if they did not question the statement.”
Musk’s broader narrative about advancing civilization is intertwined with a sense of urgency. During a presentation at SpaceX’s Starbase facility, he warned that Earth faces existential threats, including nuclear war. “There’s a high urgency to making life multi-planetary,” he said, calling Mars the only viable backup. “To do that ideally before World War III.”
Tim Wright, treaty coordinator for the International Campaign to Abolish Nuclear Weapons—the 2017 Nobel Peace Prize winner—urged Musk to leverage his influence to push for global adoption of the Treaty on the Prohibition of Nuclear Weapons. A nuclear-free world, Wright argued, would accelerate humanity’s transition toward a Type I civilization.
Hurley acknowledges that the Kardashev scale is a useful framework, but he stresses that true advancement requires more than satellite count. “Elon Musk’s scheme would not make Earth a Kardashev I civilization,” he said, “and it certainly would not make humanity a Kardashev II civilization.”
As SpaceX hurtles toward its IPO, the gap between Musk’s cosmic ambitions and the scientific consensus is widening—and regulators may soon have to decide how to weigh a claim that is part business strategy, part science fiction.
