Anthropic Drives a Major Share of SpaceX Revenue
SpaceX is expanding its artificial intelligence infrastructure as demand for computing power becomes an increasingly important part of the company’s business. In its third-quarter Securities and Exchange Commission filing, SpaceX reported that its Super Intelligence segment generated $7.56 billion, approximately 52% of total quarterly revenue of $14.58 billion.
The Super Intelligence segment includes computing services, software, and advertising. It reported $431 million in operating income, reversing a $1.72 billion operating loss recorded a year earlier. However, the company’s revenue is heavily concentrated among a small number of major customers.
Bloomberg identified Anthropic as SpaceX’s largest customer, citing a person familiar with the relationship. SpaceX’s filing did not name the customer, instead identifying it as Customer B, but disclosed that the account represented 34.5% of third-quarter revenue.
SpaceX Defends Computing Agreement as Anthropic Plans IPO
The concentration of revenue has drawn scrutiny following unverified claims that Anthropic could decline to extend its computing agreement with SpaceX beyond mid-2027. Elon Musk responded to speculation about the agreement on X on Nov. 11, stating:
“We would be happy to take the compute back. No problem. But I think the opposite is going to happen.”
The speculation emerged as Anthropic prepared for a major initial public offering. In a Nov. 10 filing, Anthropic proposed selling 825 million shares at between $70 and $78 each. The offering could raise between $57.75 billion and $64.35 billion before underwriting fees. Anthropic applied to list on Nasdaq under the ticker ANT, subject to completion of the offering.
Anthropic’s amended SEC filing, also submitted Nov. 10, detailed computing agreements with SpaceX.AI LLC valued at up to $120.5 billion over terms extending into 2029. Monthly payments are expected to reach approximately $3.1 billion once all contracted capacity becomes available, which is currently anticipated in December.
After the initial noncancelable periods expire in January and March 2027, either company can terminate the relevant agreements with 90 days’ written notice. The terms make the relationship significant for both Anthropic’s computing capacity and SpaceX’s revenue outlook.
SpaceX Bets on Sustained AI Computing Demand
The Anthropic agreement and SpaceX’s broader infrastructure expansion reflect Musk’s bet that demand for AI computing power will remain strong. Musk has previously defended SpaceX’s long-term ambitions amid criticism of its AI computing arrangements.
Venture capitalist Chamath Palihapitiya has suggested that limited computing supplies could improve SpaceX’s negotiating position. Musk has also acknowledged the risk that cheaper and more abundant computing capacity could reduce revenue.
Anthropic maintains substantial computing relationships with Google, Amazon, Microsoft, and other providers. Decentralized AI computing networks offer a separate model by distributing processing capacity among independent operators, but those networks remain distinct from the large corporate facilities supporting Anthropic’s agreements.
Arizona AI Project Faces Regulatory Review
SpaceX is separately pursuing Musk’s plans for space-based AI computing, including orbital data centers intended to operate beyond terrestrial infrastructure. The company faces two central tests: whether customers continue buying enough computing capacity and whether its proposed facilities receive regulatory approval.
The proposed Arizona project faces its next review on Dec. 9, when county officials are expected to consider the development amid public opposition and concerns about emergency preparedness. At a Nov. 12 meeting, the county’s Local Emergency Planning Committee reportedly approved six recommendations covering fire protection, battery storage, and emergency response capabilities. The advisory panel sought stronger safeguards before development proceeds.
Why This Matters
SpaceX’s financial results show how quickly AI computing has become central to the company’s business, while the concentration of revenue among major customers creates exposure if contracts change or demand weakens. The Anthropic agreements could provide substantial long-term revenue, but their termination provisions and the possibility of cheaper computing capacity remain important factors for SpaceX’s outlook.
The company’s planned facilities also face practical and regulatory challenges. The Arizona review will test whether SpaceX can address concerns about fire protection, battery storage, and emergency response as it seeks approval for infrastructure supporting its AI ambitions.
