Elon Musk's SpaceX has acquired his AI startup xAI, a move announced on February 2 that aims to integrate space infrastructure with artificial intelligence. The merger highlights Musk's vision of harnessing solar energy in orbit to power energy-intensive AI systems. Critics question the feasibility of launching data centers into space.
Elon Musk announced on February 2 that SpaceX would acquire xAI, his artificial intelligence company. While many news outlets described the deal as a corporate reshuffling or financial lifeline for xAI, Musk's statements point to a broader ambition: creating a vertically integrated system combining energy, computing, space infrastructure, and AI.
In December, Musk emphasized the potential of space-based industries, stating, “Space-based industries will vastly exceed the value of all of Earth, given that you could harness roughly 100,000 times more energy than Earth and still be using less than a millionth of the Sun’s energy.” He described Earth as a bottleneck and space as the key to greater throughput.
Just ten days before the announcement, Musk hinted at the scale of his plans: “If we harness even a billionth of the Sun’s power for AI/robotics, it will be a 1000X return. Money won’t mean much at that point.”
AI's growing energy demands underscore the need for innovation. Goldman Sachs projects that data center power demand will rise 50% by 2027 and over 165% by 2030. Training advanced models requires vast GPU clusters, with cooling posing significant challenges; Nvidia's latest chip, for instance, is optimized for better energy efficiency.
Musk's strategy involves SpaceX building orbital power grids. Two days before the merger, SpaceX filed a request with the Federal Communications Commission (FCC) to launch a massive orbital data center using reusable rockets to deploy a solar-powered satellite constellation. According to SpaceX, these facilities would have low maintenance costs and constant sunlight, as it is “always sunny in space.” This could meet xAI's energy needs, enabling larger computations and problem-solving, Musk predicts.
Skepticism persists. Robert Cyran of Reuters wrote, “Talk of launching data centers into space, sounds somewhere between optimistic to delusional. The same could be said of the value public markets have ascribed to the billionaire’s corporate efforts to date.” He likened the merger to dot-com bubble failures, calling Musk's vision “even more outlandish hopes.”
The combined entity is valued at $1.25 trillion, the largest private tech company ever. The Financial Times reports SpaceX still targets an initial public offering in June, potentially raising up to $50 billion—the biggest IPO in history.
