xAI rebrands to SpaceXAI, Grok unchanged after $1.25T merger with SpaceX

xAI has rebranded to SpaceXAI, marking the final step in Elon Musk's consolidation of his AI and aerospace ventures under one publicly traded parent company. Effective July 6, 2026, the entity formerly known as xAI now operates as SpaceXAI, with its X handle switching from @xai to @SpaceXAI. The rebrand follows the all-stock merger that closed on February 2, 2026, which combined SpaceX and xAI at a valuation of approximately $1.25 trillion — $1 trillion for SpaceX and $250 billion for xAI. This was followed by the historic $75 billion SpaceX IPO in June 2026, which listed on Nasdaq under ticker SPCX and closed its first trading day up 19% at $160.95 per share.

Crucially, the rebrand is a corporate identity change only. Grok — the AI assistant inside the X app, the standalone Grok mobile apps, SuperGrok subscription, and the developer API — retains its name and remains unchanged in pricing or functionality. No product migration is required for users or developers. By folding AI, rockets, satellites, and the X social platform under a single brand, SpaceXAI now represents a vertically integrated empire with frontier AI powering both space operations and social media. Musk had signaled the rebrand in May 2026, and this execution completes the public-facing integration.
