SpaceX’s growing relationship with Anthropic is highlighting how quickly artificial intelligence computing has become an important source of revenue for the space and technology company. Anthropic represented 34.5% of SpaceX’s third-quarter revenue, according to Bloomberg reporting cited by the source, making the AI company more significant to SpaceX’s current revenue base than the U.S. federal government.

Anthropic Becomes SpaceX’s Largest Customer

SpaceX’s third-quarter filing identifies the customer as Customer B, whose revenue is classified within the company’s Super Intelligence segment. That segment generated $7.56 billion of SpaceX’s total $14.58 billion in third-quarter revenue, underscoring the growing financial importance of AI computing within the broader business.

The reported concentration is significant because a single customer accounting for more than one-third of quarterly revenue creates a direct connection between SpaceX’s financial performance and Anthropic’s computing requirements. It also illustrates the scale of capital being committed to AI infrastructure as leading AI companies expand their access to computing capacity.

Contracts Could Reach $120.5 Billion

Anthropic has agreed to spend as much as $120.5 billion under computing contracts with SpaceX through 2029, according to Bloomberg, citing Anthropic’s IPO disclosures. The agreements are expected to involve approximately $3.1 billion in monthly spending beginning in December, representing a potentially substantial and recurring source of revenue for SpaceX’s AI computing operations.

The scale of these contracts suggests that SpaceX is positioning its computing business as a major component of its long-term growth strategy. At the same time, the contracts are not equivalent to guaranteed revenue through 2029. According to the reported terms, Anthropic can terminate the agreements with 90 days’ notice beginning in early 2027, leaving SpaceX exposed to changes in Anthropic’s computing needs or strategic priorities.

AI Revenue Changes SpaceX’s Business Profile

The development represents a broader shift in SpaceX’s revenue composition. While the company remains closely associated with its space operations, the Super Intelligence segment’s contribution demonstrates the growing role of AI computing infrastructure in its commercial strategy.

For investors and private-market analysts, the concentration of revenue in Anthropic also introduces a different form of risk. A large customer can provide substantial visibility when contracts remain active, but it can also make revenue growth more sensitive to a single counterparty’s financial position, technology strategy and infrastructure requirements.

Customer Concentration Becomes a Key Variable

SpaceX shares were down 4.01% at 10:00 a.m. ET, reflecting market attention to the company’s evolving revenue profile and the implications of its relationship with Anthropic. The decline also highlights the scrutiny surrounding the sustainability of AI-related revenue as companies invest heavily in computing capacity.

Going forward, investors will watch whether Anthropic’s computing commitments remain on track and whether SpaceX can diversify its AI customer base. The ability to convert the current concentration into a broader portfolio of long-term customers could reduce dependency risk, while any changes to Anthropic’s contracts after early 2027 could become an important factor in SpaceX’s revenue outlook. The development nevertheless underscores the growing intersection between AI infrastructure, private technology markets and SpaceX’s expanding commercial ambitions.
