Masayoshi Son Rejects Orbital Data Centers to Prioritize Terrestrial AI

Masayoshi Son, founder and CEO of SoftBank Group, rejected the economic viability of orbital data centers during a shareholder meeting for SoftBank's mobile unit on June 23, 2026. He dismissed proposals championed by Elon Musk and Jeff Bezos, arguing that potential electricity savings from space-based solar power are offset by prohibitive hardware, transportation, and maintenance costs, as well as communication latency.

Son asserted that the AI race will be decided by compute capacity on Earth over the next few years, rendering long-term orbital projects impractical. To secure a competitive advantage, SoftBank is prioritizing terrestrial infrastructure, including a $65 billion commitment to OpenAI and pledges of hundreds of billions more for global infrastructure. Additionally, SoftBank's telecom unit, led by Junichi Miyakawa, is preparing to enter the U.S. neocloud and storage battery markets, with a Japanese neocloud launch scheduled for this year.

These comments follow a historic IPO for Space Exploration Technologies Corp., though market analysts at Morningstar and traders on Kalshi share Son's skepticism regarding the operational success of space-based computing within the next decade. While Son acknowledged Musk as a remarkable agent of change, he maintained that orbital alternatives are more expensive than the terrestrial grid and water constraints they intend to solve.
