As Elon Musk pitches data centers in orbit to power the next wave of AI compute, skepticism is mounting -- and SoftBank's Masayoshi Son, himself one of AI's biggest spenders, is among the doubters.

Prediction markets price a public release before June 30 at roughly 7%, even as xAI ships smaller updates like Grok Voice and Grok Imagine Video.
