Unprecedented in its scale, the now official merger between SpaceX and xAI sheds light on Elon Musk’s vision of the future of artificial intelligence and reflects his desire to structure a leading project on an industrial scale.
So yesterday SpaceX announced the acquisition of xAI in a transaction carried out entirely in shares, valuing SpaceX at 1 trillion dollars and xAI to 250 billion dollarsi.e. a combined valuation of 1.250 billion dollars.
The operation, confirmed by Elon Musk in a press release entitled “xAI joins SpaceX to Accelerate Humanity’s Future”, comes as SpaceX is still considering an IPO, likely to raise up to 50 billion dollarswhich would make it the largest IPO ever.
Beyond these figures, spectacular even on the scale of global tech, the merger must be seen as something other than a simple financial consolidation. It reflects a much more structuring ambition, namely to place artificial intelligence in a heavy infrastructure logic, at the crossroads of space, telecommunications and intensive computing. A project which, as it becomes clearer, raises major questions about its economic, technological and political implications.
AI thought of as critical infrastructure
The merger between SpaceX and xAI must be understood in light of recent developments in AI. As models increase in size and complexity, their marginal cost increases, and the central question is no longer just about the algorithm, but about sustainable access to computation, energy and data flows.
From this perspective, SpaceX should not be seen as simple financial support. The company brings much more with a set of structuring assets, whether it is its launch capacity, access to low orbit, but above all Starlink, whose constellation provides global connectivity coverage. For its part, xAI concentrates the most calculation-intensive uses, with continuous needs in processing power for the training and inference of its models.
The joining of the two entities draws a first outline of an integrated chain, which goes from the physical infrastructure to the software layer, including distribution, a continuity which constitutes the basis of the vision defended by Elon Musk.
A capitalistic arrangement to face the reality of costs
The group takes its competitors on the wrong foot, embarked on a series of spectacular fundraising campaigns. Thus, to meet its massive financing needs to support capital-intensive investments, xAI is, via this merger, part of an internalized financing logic. The recurring cash flows generated by Starlink allow Elon Musk to limit the use of successive and dilutive fundraising, while securing the investment capacity necessary to support the rise of the AI activity.
The challenge of spatial calculation
But beyond the immediate financial aspect, one of the most commented on elements of the project lies in the idea that calculation intended for AI could, in the long term, be more efficient in space. The argument is based on several factors, starting with the availability of solar energy, the absence of land constraints, and the cooling possibilities different from those of terrestrial data centers.
On an industrial level, however, the project remains surrounded by numerous uncertainties. Deploying and operating on-orbit computing infrastructures involves high upfront costs, unprecedented operational constraints in terms of maintenance and resilience, as well as increased dependence on regulatory frameworks.
An integration that redraws industrial boundaries
The merger between SpaceX and xAI takes a logic of vertical integration already visible in other Musk projects very far. Where most AI players rely on existing cloud infrastructures, this setup seeks to internalize all critical dependencies.
This approach offers the potential advantage of reducing vulnerability to third-party arbitrage, whether economic or geopolitical. It also involves a counterparty with a high concentration of risks. The slightest industrial failure, a space accident or a tightening of regulations would simultaneously affect several links in the chain.
A lever of power beyond technology
But above all, the rapprochement between SpaceX and xAI must be seen beyond just the technological field. It is part of a reading of the conquest of space as a lever for recomposing geopolitical balances.
By converging artificial intelligence and orbital infrastructure, Elon Musk is banking on industrial continuity likely to redraw the boundaries between public and private actors. This dynamic opens up new perspectives, and questions us about the capacity of current political and regulatory frameworks to absorb the emergence of global infrastructures operated by non-state actors.
As space becomes an extension of terrestrial infrastructures, it establishes itself as a new terrain of negotiation and tensions, where the balances of the world to come will be played out. It remains to be seen who will be able to participate.
