# SpaceX absorbs xAI in a $1.25 trillion merger

Full title: SpaceX absorbs xAI in a $1.25 trillion merger (later rebranded SpaceXAI)

In early February 2026 Elon Musk's SpaceX combined with his AI company xAI (maker of Grok, owner of X), in a deal reported at a combined $1.25 trillion valuation - the largest merger ever. The rationale was pitched as merging Starlink and launch capacity with frontier AI, including orbital data centers. By August 2026 Grok models were being released under the "SpaceXAI" brand.

## Key facts
- Bloomberg reported the combination on 2026-02-02; CNBC called it the biggest merger of all time (2026-02-03)
- Combined valuation reported at $1.25 trillion
- Stated strategic rationale: orbital data centers combining Starlink's satellite network with xAI's models
- xAI's January 2026 funding announcement was the only official confirmation that Grok 5 was in training (per trackers)
- By Aug 2026 xAI's site and model launches (Grok 4.6, Grok 4.7) used the brand 'SpaceXAI'
- The merged company went public on Nasdaq as SPCX on 2026-06-12

## What happened

On 2026-02-02 Bloomberg reported that SpaceX would combine with xAI ahead of a planned mega-IPO; CNBC on 2026-02-03
described the deal as the biggest merger ever, valuing the combined company at $1.25 trillion. xAI (which had
already absorbed X/Twitter in 2025) thus became part of SpaceX. Press coverage framed the rationale around
**orbital AI data centers**: pairing Starlink's satellite mesh and SpaceX launch capacity with xAI's Grok models
to move compute into space (constant solar power, radiative cooling).

After the merger, xAI's announcements appear under the name **SpaceXAI** (e.g. "Introducing Grok 4.6 | SpaceXAI").

## Why it matters

It fused a frontier AI lab with the world's dominant launch provider and a large satellite network, giving xAI access
to public-market capital (via the June 2026 SpaceX IPO) and a unique compute-in-space thesis. It also means investors
buying SpaceX stock are buying Grok, X and SpaceX together.

Unverified details: exact exchange ratio and deal terms were not read from a primary filing.
