SpaceX’s acquisition of xAI, valued at approximately $1.25 trillion, represents one of the most consequential mergers ever announced in the technology and aerospace sectors. It also promises to be controversial, just as another Musk-buys-Musk deal was a decade ago. The combination is likely to face significant pushback, and with good reasons grounded in antitrust and national security.
Elon Musk founded SpaceX in 2002. He owns 42% of its equity and has 79% voting rights. In March 2023 he founded xAI, where he remains CEO and majority owner. According to CNBC, the deal merges SpaceX’s roughly $1 trillion valuation with xAI’s estimated $250 billion through a share‑exchange transaction. This consolidation brings together launch dominance, global satellite communications, and next-generation artificial intelligence under one private enterprise, all to achieve Musk’s vision of an integrated space-based solar-powered AI-compute infrastructure. Bloomberg reports that SpaceX is preparing for a potential IPO which could deliver an enterprise worth more than $1.5 trillion.
Why SpaceX Says It Needs Orbital Compute
Fox Business reported that SpaceX pursued the acquisition because it believes terrestrial data‑center growth will soon hit energy, land‑use, and cooling constraints. Musk maintains that the long‑term, lowest‑cost method of powering large‑scale AI compute is to move it off Earth, where continuous solar power and natural radiative cooling enable hyperscale computing without the burdens placed on terrestrial grids.
NBC News noted that Musk expects orbital compute to become cost‑competitive within just a few years, with Starlink V3 satellites and future Starship‑launched platforms serving an extraterrestrial AI infrastructure. Specifically, it would combine Falcon and Starship for launch capacity, Starlink for in-orbit infrastructure, Grok for AI models, and planned orbital data‑center constellations.
What Concerns Does the SpaceX / xAI Deal Raise?
A merger of this scale raises immediate antitrust and national‑security concerns in at least these categories.
Federal contracts: SpaceX manages billions in NASA, DoD, and intelligence‑community contracts.
Corporate governance: Intertwined leadership roles and sensitive data flows exist across Musk’s companies.
Market power: SpaceX’s ambition to deploy up to one million satellites to enable orbital AI computing is a scale that could create structural advantages difficult for competitors to match.
Global security power: Musk’s ownership of thousands of Starlink satellites makes him uniquely powerful as a private actor in global security. Starlink forms a vast, resilient communications network that militaries and governments rely on, while its sheer scale affects orbital safety and international strategic planning. This gives Musk’s companies an influence over national‑security dynamics that rivals that of nation‑states.
Who Competes in the Orbital Compute Space?
The rapid consolidation of launch services, satellite networks, and AI development within SpaceX intensifies questions about competition in the emerging market for orbital AI compute. Several companies are exploring this domain, but none match SpaceX’s level of vertical integration.
Google is developing Project Suncatcher, a 2027 prototype constellation using satellite‑borne TPUs to run AI workloads, but it remains years away from operational orbital compute despite its unmatched chip expertise and cloud dominance.
Axiom Space is building dedicated orbital data‑center modules and has already demonstrated relevant hardware on the ISS, positioning itself as a neutral orbital cloud provider for sovereign and commercial customers.
Loft Orbital has flown multi‑node AI compute systems in space and serves as a key defense integrator through partnerships such as SDA’s NExT program, lowering barriers for rapid deployment of AI‑enabled spacecraft.
Amazon’s Project Kuiper remains behind schedule and focused on broadband rather than compute, while Jeff Bezos’ Blue Origin is exploring orbital data‑center concepts but has no public program comparable to SpaceX’s filings.
Startups like Starcloud have demonstrated in‑orbit GPU operations, including the first NVIDIA H100 in space, but they lack the capital and launch‑integration capacity required to compete at constellation scale.
Defense contractors such as Northrop Grumman, Ball Aerospace, and Lockheed Martin support advanced satellite and SDA programs, but they are not building open, commercially accessible orbital cloud platforms.
Ten Years After: Tesla’s 2016 Acquisition of SolarCity
With the SpaceX / xAI deal, Musk sees a three-pronged vertical integration of companies he partially owns, marrying rocket launch dominance, global satellite communications dominance, and frontier artificial intelligence. Ten years ago, he saw similar synergies between two other companies – Tesla and SolarCity – when he owned approximately 20% of each. The deal he struck was controversial, though it was ultimately resolved in Musk’s favor after seven years of litigation.
In 2016, Tesla was expanding but financially strained. Its $2.6 billion acquisition of SolarCity—the nation’s largest residential solar installer—ignited a major corporate‑governance dispute. SolarCity, founded by Elon Musk’s cousins and chaired by Musk, carried $1.5 billion in debt. Critics said Tesla was rescuing a distressed affiliate, pointing to Musk’s overlapping roles. Tesla argued the deal fit its plan for an integrated clean‑energy ecosystem combining EVs, solar, and storage.
Shareholders sued, claiming the transaction was a conflicted bailout. They alleged Musk dominated Tesla’s board, blocked an independent negotiating committee, and pushed the company to buy a nearly insolvent firm. The case triggered an “entire fairness” review under Delaware law, examining both process and price. Although the court faulted Tesla’s process—especially its failure to shield negotiations from Musk’s influence—it found no financial harm to Tesla or its shareholders.
In 2022, the Delaware Court of Chancery held the deal was fair and that SolarCity was not insolvent. The Delaware Supreme Court affirmed in 2023, citing independent advisors, arm’s‑length negotiations, and evidence that the price was reasonable. For Tesla, the acquisition accelerated its shift toward a fully integrated clean‑energy company. For corporate‑governance observers, the case underscores a lesson: even when a deal is financially sound, weak conflict‑management safeguards can invite years of costly litigation.
The parallels between the SpaceX / xAI deal and the Tesla / SolarCity are striking, but the facts matter and need to be fleshed out.
Antitrust Investigation a Must
SpaceX’s acquisition of xAI places the combined company at the center of a rapidly forming market for orbital AI compute. Google is the strongest long‑term contender; Axiom is the most mature commercial operator; Loft is the leading defense integrator; Amazon and Blue Origin are strategically significant but years behind in compute. Startups are advancing feasibility, and defense primes provide critical infrastructure.
For now, however, SpaceX stands alone as the only company with proprietary launch capacity, operational broadband mega-constellations, high‑speed laser-based data transmission, in‑house AI model development, and a formal FCC filing for a dedicated orbital compute constellation.
Dan Primack, business editor at Axios, wrote that this is a possible prelude to a future merger with Tesla, which has invested $2 billion into xAI. “Tesla would make the chips, SpaceX would be responsible for launch and satellites, and xAI would build the models and agentic networks,” he wrote, adding it’s a possibility that could threaten rival and unlikely collaborator OpenAI, which he cofounded.
Primack predicted that SpaceX investors may balk at the deal “because the finances of this all-stock merger are ludicrous.” He wrote that the deal dilutes SpaceX shareholders and complicates any IPO, but SpaceX needs money. “For xAI investors, this is something of a bailout. Similar to what the xAI-X merger was for those who helped take Twitter private,” Primack wrote.
Musk’s universe is nothing if not complicated. His time as head of the Trump administration’s much criticized DOGE program and his bizarre chainsaw-waving appearances at political rallies remain fresh in the minds of many Americans.
More recently, X is facing some definitively terrestrial complications. On Feb. 3 in Paris, French prosecutors raided the company’s offices in an expanding criminal probe into suspected algorithm abuse, fraudulent data extraction, child sexual abuse material, and sexually explicit AI‑generated deepfakes linked to the platform and its Grok AI system.
Launched in January 2025 and supported by Europol, the investigation has widened to include Holocaust‑denial content and manipulation of automated data‑processing systems. Musk and former CEO Linda Yaccarino have been summoned to appear for interviews. The UK has opened its own inquiry into Grok’s data practices and generation of harmful content.
The road to make Musk’s vision for an orbital solar-powered AI constellation a reality promises to be a bumpy one. This substantial vertical integration—and the merger bringing AI fully inside the world’s most capable launch and satellite operator—creates a market structure antitrust law enforcers should examine vigorously. Even beloved cartoon character George Jetson’s employer, Spacely Sprockets, might pump the brakes on such a deal.
