SpaceX CEO Elon Musk and OpenAI CEO Sam Altman famously don’t agree on much.
The latest point of contention: data centers in space. Musk has made it a priority. Altman thinks it’s a fantasy, at least for now.
“I honestly think the idea with the current landscape of putting data centers in space is ridiculous,” Altman said during a live interview with local media in New Delhi on Friday, causing audience members to laugh.
Altman said that orbital data centers could “make sense someday,” but factors like launch costs and the difficulty of repairing a computer chip in space remain overwhelming obstacles.
“We are not there yet,” Altman added. “There will come a time. Space is great for a lot of things. Orbital data centers are not something that’s going to matter at scale this decade.”
Musk would almost certainly disagree.
While many Big Tech and AI companies are spending billions on data center construction on Earth, Musk’s eyes are on the stars, per usual. Orbital data centers are his latest ambition, as he mentioned in an all-hands xAI meeting in December.
In February, SpaceX said its goal is to launch a “constellation of a million satellites that operate as orbital data centers.” The company has already begun hiring engineers to make that happen.
During an all-hands meeting with xAI employees this month, Musk said SpaceX’s acquisition of xAI will allow them to deploy the orbital data centers faster.
Despite Altman’s skepticism, other tech leaders are also racing to place data centers in space. Google’s Project Suncatcher, unveiled in November 2025, aims to do just that. Google CEO Sundar Pichai told Fox News Sunday the company could start placing data centers — powered by the sun — in space as early as 2027.
Tech and AI companies rely on data centers to power their products, like large language models and chatbots. Those data centers, however, can deplete water resources, strain power grids, increase pollution, and decrease the overall quality of life.
An investigation by Business Insider published last year found that over 1,200 data centers had been approved for construction across the US by the end of 2024, nearly four times the number from 2010.
Now, proposed data center campuses in Texas, Oklahoma, and elsewhere are increasingly facing stiff resistance from local communities.
