SpaceXAI
SpaceXAI is the AI division of SpaceX, formed after SpaceX acquired xAI in February 2026 and rebranded it in July 2026. The entity combines SpaceX's space infrastructure, satellite network, and launch capabilities with xAI's Grok AI models and Colossus data centers. A spin of the xAI story (xai-ai-lab), SpaceXAI represents the merger of space and AI under a single corporate identity.
