Elon Musk's AI company no longer exists under its own name. On July 6, 2026, xAI — the maker of the Grok chatbot — completed its rebrand to SpaceXAI, unveiling a new logo and X handle and finalizing its absorption into SpaceX.
From acquisition to erasure
SpaceX acquired xAI in an all-stock deal valued at about $1.25 trillion that closed on February 2, 2026. In May, Musk said xAI would be dissolved as a separate entity and folded into SpaceX, with its AI products rebranded SpaceXAI. The July 6 rebrand completes that plan, retiring the xAI name barely three years after the company was founded.
Why "Space"
Musk has framed the logic around building AI compute in orbit. SpaceX has filed with the FCC to launch up to one million satellites designed to act as AI compute nodes in low Earth orbit — powered by uninterrupted solar energy and cooled by radiating heat into space, sidestepping the terrestrial grid constraints that are throttling data-center growth. It is an audacious, still-unproven vision, but it explains the name.
The financial backdrop
The rebrand follows SpaceX's blockbuster June IPO — the largest public offering ever, raising about $75 billion at a roughly $1.77 trillion valuation. Consolidating Grok and the AI research group under the SpaceX banner puts Musk's models, launch capacity and satellite network inside a single publicly traded company.
What it changes
For users, Grok and related products now carry SpaceXAI branding, with tighter integration expected across Starlink and X. Skeptics note the orbital-datacenter pitch faces hard engineering problems — heat rejection, latency, radiation and the impossibility of on-site repairs — and argue the branding is running well ahead of the hardware. Either way, the corporate structure is now settled: there is no more xAI.
