SoftBank Group CEO Masayoshi Son reportedly rejected the case put forward by Elon Musk’s SpaceX to build AI data centres in space, arguing the economics favour terrestrial infrastructure.

Bloomberg cited comments made by Son at SoftBank’s annual shareholder meeting, who stated the “the main advantage” of eliminating electricity costs by putting AI data centres in space is outweighed by “higher fees to transport everything into space, maintenance and communication delays”.

Son was apparently responding to a shareholder who asked whether SoftBank would pursue a strategy similar to that proposed by the SpaceX chief, who filed for US regulatory approval in February to deploy up to 1 million solar-powered satellites designed to operate as AI data centres. Musk argues persistent access to solar power will “achieve transformative cost and energy efficiency”, adding “in the long term, space-based AI is obviously the only way to scale”.

While describing the tech mogul as a “remarkable agent of change”, Son reportedly said SoftBank would instead focus on building “formidable” data centre capacity on Earth. “In the battle for AI, the next few years will be far more important than what might happen a decade or so from now,” he noted, adding “he who strikes first wins”.

Despite intensifying competition, Son argued AI has scope for “ten-fold, a hundred-fold” growth, adding there was ample room for OpenAI and rivals including Anthropic and Google to expand amid accelerating AI demand.

The remarks put Son’s strategy at odds with Musk’s long-term vision for AI. SpaceX launched a record-breaking $75 billion IPO earlier this month, with proceeds funnelled towards funding its space-based AI initiative alongside the expansion of its Starlink satellite network.

Meanwhile, SoftBank has committed around $65 billion to OpenAI despite reports the investments were straining its balance sheets, and pledged to invest hundreds of billions of dollars in terrestrial AI infrastructure and data centres globally.
