SpaceXAI
playerAI & Compute
Musk's AI company, now part of SpaceX, sells Anthropic its computing power and is under investigation in New York.
Who they are
SpaceXAI, Elon Musk's AI company (formerly xAI).
What they do
It makes Grok and released Grok 4.6 in August 2026. In September it and X dropped their antitrust claims against Apple, and New York City subpoenaed it and Musk in an AI safety investigation.
How it works
It runs huge data centres. Anthropic pays it $1.25 billion a month for the entire output of its Colossus 1 data centre.
Why it matters
It sells computing power to a rival AI company while SpaceX owns Cursor, one of that rival's biggest customers.
