Following revelations published by Reuters on the exploration of merger scenarios between SpaceX, Tesla and X.ai controlled by Elon Musk, interpretations quickly multiplied within the tech community. Some see it as the outline of an extraordinary conglomerate, others as a tactical maneuver ahead of a historic IPO. Between industrial projections and stories of disruption, the debate quickly heated up.
Rather than extending or commenting on these speculations, it is appropriate to return to the established facts to precisely measure their significance, because what this information reveals is not the existence of a unified project already structured, but a phase of strategic exploration, constrained by very concrete realities: financing, access to computing, energy and the rise of heavy infrastructure, now central in the race for artificial intelligence.
Proven capitalistic discussions, without recorded decision
First tangible element, SpaceX is actively working on preparing an IPO. Several concordant sources mention an IPO as early as 2026, for a target valuation of around $1,500 billion, with a potential raising of up to $50 billion. The creation, in January, of legal structures of the type merger sub in Nevada, involving the financial director of SpaceX, is part of classic practices of preparation for complex capital operations.
In this perspective, discussions did take place around two options, on the one hand a merger between SpaceX and Tesla, and on the other a combination between SpaceX and xAI. Reuters has confirmed the exploration of a share exchange scenario between SpaceX and xAI, with the possibility for certain xAI executives to opt for a cash settlement. However, no agreement has been announced, and no final decision has been communicated.
These exchanges must therefore be understood as working hypotheses, but what is their meaning and above all what do they say about the change of scale and its geopolitical impacts?
Industrial perimeters which remain, for the moment, distinct
If we stick to the operational plan, the three companies are pursuing largely autonomous trajectories.
SpaceX remains an industrial space player, focused on increasing its launch rate and developing Starship. The company is investing massively in its production capacities and in its ground infrastructure, with the stated objective of supporting an unprecedented rate of flights and, in the longer term, lunar and Martian projects.
Tesla, for its part, is today as much an energy company as an automobile manufacturer. Its stationary energy storage activities, notably through its large-scale battery systems, are already deployed on an industrial scale. At the same time, the group is continuing the development of its humanoid robot Optimus, still at the experimental stage, but presented as a long-term strategic axis.
xAI remains a more recent structure, focused on the development of artificial intelligence models. Like the entire sector, it is faced with a major constraint: access to computewhich has become a differentiating factor as much as a growth lock.
Space, energy, calculation: declarations that open up the field of possibilities.
Elon Musk recently spoke publicly about the convergence between space, energy and artificial intelligence, notably in Davos, during the World Economic Forum, emphasizing a specific point: energy now constitutes one of the main limiting factors in the development of large-scale AI. In this context, he mentioned solar energy, both on Earth and potentially from space, as an avenue for meeting, in the long term, the growing needs of computing infrastructures.
If these remarks are not connected to any operational reality, there is at this stage no industrial program for orbital computing centers, the prospect of such projects is however perfectly possible.
Convergence dictated by AI constraints
This hypothesis is based on a triptych that has become structuring for large-scale artificial intelligence, namely the necessary computing capacity, access to abundant energy and the mobilization of capital over long horizons. On each of these axes, tensions are increasing. THE compute is concentrated and expensive, energy becomes an explicit constraint factor, including in economies hitherto considered abundant, as for capital, it must be committed to very capital-intensive projects, comparable to industrial or energy infrastructures.
In this context, the scenarios raised around SpaceX should be read not as the announcement of an imminent integration between AI, energy and space, but as the exploration of solutions to support massive, continuous and low-liquid investments, on the scale required by contemporary AI.
SpaceX, a central asset
In this context, SpaceX appears to be a central asset in current discussions. The company is today one of the only ones in the world capable of raising amounts historically reserved for state programs, especially since it is one of the only ones to capture the attention of sovereign funds and infrastructure investors with sufficiently deep pockets.
A private geopolitics that is still hypothetical, but with implications that politicians must grasp
Ultimately, what is visible in the shadows deserves special attention. For the first time in several decades, private companies are considering simultaneously controlling levers historically reserved for public power. Access to space, the capacity to produce and store energy on a large scale, and the exploitation of critical computing infrastructures constitute, together, a base of power whose combination goes beyond the simple economic framework.
Who sets the rules when a private company operates essential infrastructure outside the national territory? What jurisdiction applies to computing capabilities located in orbit? What control capacity do States have over assets financed by private capital but with obvious strategic uses? So many questions that are still largely open, which public officials will have to question, otherwise they will see these issues structured outside the traditional political framework.
