Musk Says Space Will Be the Cheapest Place to Run AI Within Three Years — Here’s Why That Would Upend the Cloud

Elon Musk told a podcast that within 30–36 months running large AI clusters in space will be far cheaper than on Earth, arguing terrestrial power constraints, grid bottlenecks and supply‑chain limits make orbital solar arrays economically superior. He cited higher energy yield from space solar, lower need for batteries, and simpler approvals versus terrestrial PV, while acknowledging engineering and regulatory hurdles remain.
