HAWTHORNE, CA — Elon Musk has declared that SpaceX is destined to become the world's most dominant force in artificial intelligence. In a series of bold statements on March 16, 2026, Musk predicted that within a few years, SpaceX's AI achievements would "far exceed everyone else combined" — including industry leaders like Alphabet's Google DeepMind. The claim arrives on the heels of a sweeping corporate restructuring that has fused Musk's aerospace empire with his AI ambitions, and positioned the combined entity for what could become the largest IPO in history.
The Merger: Vertical Integration of Space and Silicon
On February 2, 2026, SpaceX completed an all-stock acquisition of xAI — which had previously absorbed the X social media platform . The deal valued the combined entity at $1.25 trillion, folding the Grok chatbot, the X data firehose, and xAI's research talent directly into the aerospace giant under a single corporate umbrella.
The strategic logic is straightforward but audacious. Musk argues that Earth-based data centers are approaching a "power wall" — a hard ceiling on AI compute capacity imposed by terrestrial power grid constraints. By merging the two companies, he intends to use Starship to launch Orbital Data Centers (ODCs) that leverage constant solar energy and the natural cooling of space to power massive AI clusters at a scale impossible on the terrestrial grid.
The "Sentient Sun" Project
At the center of SpaceX's AI infrastructure ambitions is a classified-but-leaked initiative internally called the "Sentient Sun" project. The initiative aims to build space-based compute at a scale that is physically impossible within terrestrial power constraints, with a target of adding 100 gigawatts of AI compute capacity via satellite constellations within the next three years.
The proposition draws directly on SpaceX's existing Starlink constellation and Starship launch cadence. Unlike terrestrial data centers — which require new power plants, transmission infrastructure, and cooling systems — ODCs would be supplied by continuous solar exposure and cooled passively by the thermal sink of space. Musk has described this as the only realistic path to "gigawatt-class AI" without waiting a decade for grid expansion.
The $1.75 Trillion IPO
The market has responded to the merger with a significant re-rating. SpaceX is reportedly preparing for a public listing with internal valuations now climbing toward $1.75 trillion as analysts reprice the company's identity from an aerospace contractor to a vertically integrated AI-infrastructure platform.

If realized, a $30–50 billion capital raise would eclipse Saudi Aramco's 2019 IPO — the current record holder at approximately $29.4 billion — making SpaceX's listing the largest in history.
Internal Rebuilding: The "Foundations Up" Strategy
The transition has not been without significant friction. As of March 18, 2026, 9 of xAI's 11 original co-founders have departed the company, including key technical figures Tony Wu and Zihang Dai — researchers who were central to Grok's early architecture and training methodology.
Musk publicly acknowledged the "talent flux" on X, stating that xAI "was not built right the first time around" and is currently being redesigned from the foundations up to align with the rigid, milestone-based engineering culture of SpaceX. The framing signals a deliberate cultural reset rather than a retention failure — Musk is choosing SpaceX's operational philosophy over xAI's research lab culture.
SpaceX vs. The "Chatbot" Giants
Musk's confidence that SpaceX will "surpass DeepMind" hinges on a deliberate redefinition of what AI competition actually means. Rather than measuring labs by benchmark scores or model size, Musk is pointing to three structural advantages:

Whether the strategy works depends on factors no one can model cleanly: whether Starship achieves the launch cadence needed to populate orbital compute clusters, whether the talent lost in xAI's co-founder exodus can be replaced, and whether "physical AI" proves to be a more durable moat than the transformer-scale advantages held by OpenAI and Google DeepMind . For now, the market is voting yes — at $1.75 trillion.
