SpaceX plans to build factories on the moon with robotic help, Elon Musk said Tuesday during the company's first-ever quarterly earnings call, doubling down on a vision he first outlined earlier this year.
What Happened
"We are going to land a lot of tonnage on the moon," Musk said. "We're going to build the factories on the moon. The robots will be helpful with that." He added: "Using robots on the moon to scale up manufacturing on the moon — which, I know it sounds, like, super sci-fi right now, but it's going to happen — will enable us to build the mass accelerator on the moon."
The factories would produce SpaceX's Starmind AI satellites, with the company aiming to operate a million-strong constellation in Earth orbit and eventually launch locally made craft from the lunar surface using electromagnetic mass drivers — essentially extremely powerful rail guns. Musk also referenced "solar and radiator production" on the moon as key components for powering and cooling those satellites.
Musk didn't provide details about the robotic labor force, but he has previously said SpaceX will launch some Optimus humanoid robots from Tesla to Mars in the near future. Those units would fly on Starship, which SpaceX Chief Financial Officer Bret Johnsen said "aims to quadruple payload capacity and reduce launch costs by 10 times compared to our Falcon 9 rocket."
Tuesday's call was a landmark for SpaceX — its first as a publicly traded company after an IPO in June that raised $86 billion and valued the firm at $1.77 trillion.
Why It Matters
The lunar factory plan signals SpaceX is treating off-Earth manufacturing as a core long-term business, not just a science-fiction aside. If realized, it would tie together Starship's heavy-lift economics, Tesla's robotics, and Starmind's AI satellite ambitions — potentially reshaping how the company scales beyond Earth orbit. For investors, Musk used the earnings call to frame these projects as part of SpaceX's growth story, even as the company reported a Q2 2026 net loss of $541 million on revenue of $7.8 billion.
The Bottom Line
SpaceX is publicly committing to lunar manufacturing and robotic assembly, with Starmind satellites and mass accelerators as the stated endgame — but Musk offered no timeline or technical specifics beyond Starship's role in enabling it.
