Elon Musk’s business empire is poised for a dramatic consolidation as SpaceX prepares for a potential $1.5 trillion IPO and considers blockbuster mergers with either Tesla or xAI, Musk’s artificial intelligence startup. Multiple reports emerged Thursday night detailing these potential combinations, which would represent a significant escalation of the so-called “Muskonomy.”
The three companies have already been moving closer together operationally and financially. Tesla announced Wednesday it had invested $2 billion in xAI, following a similar investment by SpaceX last year. The electric vehicle manufacturer also revealed plans to evaluate “potential AI collaborations” with xAI, building on its integration of xAI’s Grok chatbot into Tesla vehicles last July.
A SpaceX-xAI merger aligns with Musk’s vision for space-based AI infrastructure. The world’s richest man has proposed that the future of AI data centers lies in space, where they can access abundant solar power and operate without the massive water requirements needed for Earth-based cooling systems. Speaking at Davos, Musk suggested space will become the “lowest cost” place to train AI models, announcing plans for SpaceX to launch solar-powered AI satellites within the next few years that could eventually consume “hundreds of terawatts” of energy annually.
SpaceX’s Starship rocket and Starlink satellite network could provide xAI with crucial competitive advantages over rivals like OpenAI and Google, who are also exploring space-based computing solutions. This infrastructure access comes at a critical time, as AI training remains notoriously expensive, with xAI reportedly burning through billions of dollars and regularly seeking new funding. Meanwhile, SpaceX has seen revenue growth and is preparing to tap public markets for up to $50 billion.
A Tesla merger presents a more complex scenario with less obvious synergies. Tesla is pivoting from pure carmaker to AI and robotics company, with Musk announcing plans to discontinue the Model X and S to use their production lines for the Optimus humanoid robot. Musk stated Tesla needs to build a “terafab” for advanced AI chip production, suggesting in November that these chips could power SpaceX’s solar-powered AI satellites. The common thread connecting all ventures is Musk’s obsession with Mars colonization, with plans to send Optimus robots on uncrewed Starship missions to the red planet.
Key Quotes
Space will become the ’lowest cost’ place to train AI
Elon Musk made this statement at Davos last week, outlining his vision for why AI infrastructure will inevitably move to orbital data centers. This perspective drives the strategic rationale for merging SpaceX with xAI, as it would give the AI startup exclusive access to space-based computing capabilities that competitors are only beginning to explore.
SpaceX will launch solar-powered AI satellites in the next few years that will ultimately scale up to ‘hundreds of terawatts’ of energy consumption a year
This quote from Musk at Davos reveals the massive scale of his space-based AI infrastructure ambitions. The energy requirements he describes dwarf current AI data center consumption, suggesting he envisions AI training operations far beyond what’s currently possible on Earth, making the SpaceX-xAI merger strategically critical.
Good idea
Musk wrote this in 2020 responding to a Twitter post suggesting he merge SpaceX, Tesla, and the Boring Company. This quote demonstrates that consolidating his business empire has been on Musk’s mind for years, and the current merger discussions represent the realization of long-held ambitions rather than opportunistic deal-making.
Our Take
This consolidation strategy reveals how AI development is becoming a game of vertical integration and resource control. Musk appears to be building an end-to-end ecosystem where energy production, chip manufacturing, satellite networks, launch capabilities, and AI development all feed into each other. This approach mirrors historical industrial consolidations but on a scale that spans Earth and space. The timing is particularly significant as AI companies face mounting pressure over energy consumption and computing costs. If successful, Musk could leapfrog competitors not through better algorithms, but through superior infrastructure access. However, the complexity of merging public companies like Tesla with private entities like xAI, combined with regulatory scrutiny and shareholder concerns, presents substantial hurdles. The real question is whether this grand vision can overcome practical execution challenges and whether space-based AI infrastructure will deliver on its promised advantages quickly enough to justify the massive integration effort.
Why This Matters
This potential consolidation represents a pivotal moment in the AI industry’s evolution and infrastructure development. If realized, these mergers would create an unprecedented vertical integration of AI capabilities, from chip manufacturing and data center infrastructure to satellite networks and space launch systems. The move signals a fundamental shift in how AI companies think about compute infrastructure, with space-based data centers potentially solving critical bottlenecks around energy consumption and cooling that currently limit AI model training.
The implications extend beyond Musk’s empire to the broader AI arms race. Major players like OpenAI, Google, and Microsoft are already struggling to secure sufficient computing power for increasingly large AI models. If xAI gains exclusive access to space-based computing infrastructure through SpaceX, it could fundamentally alter competitive dynamics in the AI industry. This also highlights how AI development is becoming inseparable from energy infrastructure, manufacturing capabilities, and even space exploration—requiring resources and integration that only the world’s largest companies or conglomerates can marshal. The consolidation trend may force other AI companies to pursue similar vertical integration strategies or risk falling behind in the race toward artificial general intelligence.
