Elon Musk's xAI Merges with SpaceX, Rebranded as SpaceXAI
Latest scoop, Elon Musk's AI venture xAI is shutting down independent operations, fully merging into SpaceX and rebranding as SpaceXAI, becoming the AI product division under SpaceX.
Just hours before Musk's announcement, SpaceXAI struck a deal with Anthropic, allowing them to leverage over 300 megawatts of computing power from SpaceXAI's AI supercomputers. Both parties plan to collaborate on developing several gigawatts of orbital AI computing power.
Musk also mentioned that SpaceX will provide computing resources to other AI companies, provided they use their models for the benefit of all humanity.
xAI was founded by Musk in 2023, with a founding team that includes core AI talents from top-tier institutions like OpenAI and Google DeepMind. Initially set up as a non-profit entity, its core mission was to “understand the nature of the universe.”
The company not only launched the AI chatbot Grok but also built the "Colossus 1" training system, and its upgraded Colossus 2, set to launch in early 2026, will be equipped with 550,000 Nvidia GB200 GPUs, becoming the world’s first gigawatt-level AI training cluster.
In February this year, SpaceX acquired xAI through a stock-for-stock transaction. At that time, SpaceX was valued at around $1 trillion, and xAI was valued at $250 billion, resulting in a combined valuation soaring to $1.25 trillion, setting a record for the highest valuation in corporate mergers.
Despite xAI notifying employees that there would be no name change in the short term after the acquisition, Musk's announcement of xAI merging into SpaceX as SpaceXAI signifies the completion of their integration efforts.
Musk stated that the core of this integration is the “space computing power” strategy, as Earth's energy and heat dissipation limits will constrain AI computing power development. It's anticipated that within two to three years, the minimum cost for generative AI computation will shift to space, with SpaceXAI emerging as the “brain of space exploration” for SpaceX.
However, the merged SpaceXAI still faces numerous challenges. The xAI founding team has seen departures, and the company is “clearly lagging behind competitors”; additionally, the space computing power layout entails significant technical challenges, high investment costs, and stringent regulatory policies.
Moreover, SpaceX plans to initiate an IPO mid-year, targeting a valuation of around $2 trillion, with the merger of SpaceXAI serving as a crucial support point for its valuation, while its commercialization prospects will directly influence market expectations.
