Masayoshi Son Dismisses Musk's Idea for Orbital Data Centers

What happened

Masayoshi Son dismissed Musk's vision for orbital data centers — recently championed by xAI and SpaceX — as an alternative to power-constrained Earth-bound DCs.

Context and impact

Musk and xAI Colossus have been pushing space-based DCs (no power constraint, solar-driven). Son, who via SoftBank and Stargate is investing billions in terrestrial DCs (10GW for OpenAI), calls the approach economically unviable. A strategic split between two mega-investors in AI infra.

• Quote: 'little merit' in orbital DCs
• Son backs ground-based capacity via Stargate (10GW for OpenAI)
• Musk + SpaceX moving GPU to orbit (solar power constraint)
