SoftBank's founder picks side in space data center fight
SoftBank Group (SFTBY) founder Masayoshi Son dismissed the idea of building data centers in space, breaking publicly with the vision Elon Musk has spent the past year building toward. Son made the comments at his own company's shareholder meeting, according to a Seeking Alpha report.
The contrast is hard to miss: Elon's SpaceX is racing to put servers in orbit, while SoftBank is saying the ground is enough.
Elon's pitch rests on free electricity
Elon Musk's plan started taking shape in February, when SpaceX merged with xAI in a deal he framed as the fastest way to access power and space for AI compute, CNN reported.
Weeks later, SpaceX filed with federal regulators for permission to launch up to one million satellites built around orbital data centers.
The company has since detailed its first design, called AI1, a 70-meter spacecraft carrying up to 150 kilowatts of peak compute capacity, according to Tom's Hardware.
SpaceX has already signed a $920 million-per-month compute deal with Google tied to the project, the same report found.
The timing matters for investors. Following its historic public debut earlier this month at a $1.75 trillion valuation, SpaceX faces fresh scrutiny over how it deploys its newly raised capital.
Son says the real cost is chips, not power
Son's rejection centers on where the money actually goes. Electricity savings would be real in orbit, but power makes up only a small share of total data center costs compared with chips and other hardware, Son said at the meeting, according to Bloomberg.
Cutting the smaller expense while adding launch costs, maintenance, and communication delays does not clear the bar for him.

Communication delays alone could matter for real-time AI workloads, since signals between an orbital data center and Earth still take measurable time to travel.
Son's view of the timeline matters as much as his math. "He who strikes first wins," he said, framing the next few years as the period that decides the AI race, not the next decade. That framing favors infrastructure that can be built now, not infrastructure that depends on a rocket still in development.
SoftBank has its own reasons to bet on Earth
Softbank's argument is not neutral. The company is a lead backer of Stargate, the roughly $500 billion AI infrastructure push with OpenAI that depends on terrestrial buildouts like the one in Abilene, Texas.
SoftBank also walked away in January from a reported $50 billion bid for data center operator Switch, Bloomberg reported, a setback for the same ground-based strategy Son is now defending.

For investors tracking SoftBank Group (SFTBY), the space comments are less a tech opinion and more a defense of capital already committed.
Son has staked a large share of SoftBank's balance sheet on chips, OpenAI, and physical data centers reaching scale within the next few years.
Dismissing orbital compute as a decade-out distraction supports the urgency behind that spending today.
The space compute bet is no longer one company's idea
Musk is not alone in pursuing orbital compute, and Son is not alone in doubting it.
Google has tested its own satellite concept, called Project Suncatcher, betting that launch costs could fall toward $200 per kilogram by the mid-2030s, according to CNBC.
Amazon founder Jeff Bezos has separately predicted "giant gigawatt data centers in space" within 20 years through his own rocket venture, Blue Origin.
Not every AI executive is convinced. OpenAI chief Sam Altman has called orbital data centers "ridiculous," the same Tom's Hardware report noted, putting him on Son's side of the divide, despite OpenAI's deep ties to SoftBank's terrestrial buildout.
The split is no longer about whether the physics works. Engineers broadly agree solar power and heat radiators function in orbit, as NPR reported after reviewing the technical claims.
What separates the two camps is a bet on timing, not feasibility. Elon is wagering that falling launch costs and a still-developing Starship rocket will make orbit competitive within years.
Son is wagering that the AI race gets decided before that bet can mature, making any near-term advantage in orbit irrelevant.
Wall Street will not resolve that argument from a shareholder meeting. It will resolve it the way it resolves every infrastructure bet this size, by watching which side keeps raising capital once the timelines start slipping.
