Elon Musk is combining his rocket maker SpaceX with artificial intelligence startup xAI in a transaction that values the enlarged group at about $1.25 trillion, according to statements released Monday.

The deal, structured as a share exchange, values SpaceX at $1 trillion and xAI at $250 billion, making it the largest merger ever recorded. Under the terms, one xAI share will convert into 0.1433 shares of SpaceX. Bank documents reviewed by CNBC value SpaceX between $859 billion and $1.26 trillion, and xAI between $219 billion and $294 billion.

Musk said the merger is intended to create a vertically integrated platform combining artificial intelligence, launch systems, satellite networks, and data infrastructure. A core objective is the development of “orbital data centers,” using space-based computing to support AI workloads.

The transaction comes ahead of a potential SpaceX initial public offering later this year. The company is reported to be exploring a capital raise of up to $50 billion at valuations as high as $1.5 trillion.

xAI, founded by Musk in 2023, develops the Grok chatbot and has been burning cash as it scales computing infrastructure to compete with OpenAI and Anthropic.

Points clés à retenir

The merger highlights how capital intensity is reshaping the AI sector. Training large models and running inference at scale now requires vast energy, compute, and data capacity. By folding xAI into SpaceX, Musk gains access to a balance sheet, launch capability, and satellite network that few rivals can match. SpaceX’s assets, particularly Starlink, position the group to experiment with space-based data transmission and computing, an area Musk argues will become critical as demand for AI accelerates. The structure also reduces xAI’s reliance on repeated external funding rounds, at a time when competition with OpenAI and Anthropic is driving costs higher. For investors, the deal concentrates risk and upside into a single private vehicle ahead of a possible IPO. It also keeps control tightly with Musk, avoiding public market scrutiny while scale is still being built. The challenge will be execution. Orbital data centers remain unproven, and regulatory, safety, and cost hurdles are significant. Still, the merger signals a clear strategy: combine AI, space, and infrastructure into one platform, and fund it at a scale few others can attempt.
