From leak to signed deal took four days. On January 29, Reuters reported that SpaceX and xAI had entered merger talks; on February 2, the answer arrived: SpaceX acquired xAI in an all-stock transaction. The combined entity operates as SpaceXAI, with the merged valuation around $1.25 trillion. Musk’s merger memo was posted publicly, and TechCrunch reported an even further-out plan — data centers in space.
All-Stock, $1.25 Trillion
An all-stock structure means nobody cashes out: xAI’s shareholders become shareholders of the combined company, with both sides’ interests tied to one balance sheet. A roughly $1.25 trillion merged valuation places SpaceXAI in the weight class of the world’s most valuable companies — and this one holds launch capability, satellite connectivity, and frontier model capability at once. Capital markets will need a new framework to price it, because no existing category contains a comparison.
A Merger Memo, Published
SpaceXAI posted Musk’s merger memo. Documents of this kind are usually internal; publishing one is itself a narrative act — setting the “we are one company now” tone for employees and pre-loading the market with the combined story. At a company famous for speed, a four-day close plus a simultaneously published memo suggests a prepared script rather than an improvisation — and the moment the talks “leaked” was probably in the script too.
Orbital Data Centers Enter the Agenda
TechCrunch’s reporting points to data centers in space as part of the plan. The direction answers AI infrastructure’s current contradiction: terrestrial power, land, and cooling are not keeping up with compute demand, and the key variables for moving compute to orbit — launch cost and launch cadence — happen to be SpaceX’s home turf. The engineering problems remain enormous: heat dissipation, maintenance, radiation — each a hard campaign. But when the company that owns the rockets merges with the company that needs the compute, the option has, for the first time, both an internal customer and an internal supply chain.
What a Trillion-Dollar Player Changes
For the AI industry, SpaceXAI’s birth raises the unit of competition another level. Rival labs are no longer up against a model team but a full stack running from launch to connectivity to models. Earlier reporting noted the merger came ahead of SpaceX’s planned IPO, so public markets will soon face the question of how to price a space-AI conglomerate. Every competitor’s next move — fundraising, alliances, locking in compute — will now be measured against this new baseline.
