Anthropic accounts for 34.5% of SpaceX revenue and surpasses U.S. government contracts
Bloomberg News reported on Thursday, October 29, 2026, citing a person familiar with the matter, that Anthropic is the unnamed “Customer B” that accounted for approximately 34.5% of SpaceX’s revenue during the third quarter of the year.
This figure makes the AI development company the single largest customer for Elon Musk’s rocket, satellite, and artificial intelligence company, outpacing even the U.S. government. These funds flow through SpaceX’s AI division, now named “Superintelligence,” which sells computing capabilities.
However, Anthropic’s initial public offering filing shows that this deal could end soon; following the expiration of initial commitment periods in early 2027, either party has the right to cancel the agreement with 90 days’ prior notice.
Financial disclosure details and revenue surge for the Superintelligence division
SpaceX’s quarterly report submitted on October 22 indicated that a single customer associated with the Superintelligence sector accounted for 34.5% of third-quarter revenue according to a review by 4WeekMBA, equivalent to about $5 billion out of the $14.6 billion SpaceX brought in during the quarter.Just one year prior, the same customer was below the 10% disclosure threshold. Revenue for the Superintelligence sector surged to $7.56 billion compared to $813 million in the same quarter of the previous year, while a second customer, “Customer A,” accounted for about 16.6% of revenue across all three sectors. Anthropic declined to comment and SpaceX did not respond, according to PanNews.
The $120.5 billion agreement cap and Colossus data centers
Anthropic filed its initial public offering on Monday, October 26, and the document clarifies that it signed and amended several agreements between May and October with SpaceX AI, formerly known as xAI, to utilize computing capabilities powered by NVIDIA GPUs.
Anthropic agreed to spend “a total of up to $120.5 billion over periods extending through 2029,” according to Yahoo Finance. Payments are expected to reach about $3.1 billion per month once full expected capacity is delivered in December, noting that when unveiled in May, the deal was valued at $1.25 billion per month for capacity at Colossus data centers near Memphis, Tennessee, according to CNBC.
Flexible cancellation terms with 90-day notice and the paradox of partnership between competitors
These cancellation terms distinguish this deal from Anthropic’s other computing contracts; the initial non-cancellable periods end in January and March 2027, after which either party may cancel each agreement with 90 days’ written notice, unlike agreements with Amazon, Google, and Microsoft that include minimum commitments, according to Stock Titan.
Therefore, the $120.5 billion figure represents a ceiling rather than a guaranteed total, and the agreement brings together direct competitors as xAI models compete with Anthropic’s Claude model, meaning the customer responsible for a third of SpaceX’s revenue last quarter will be able to walk away with a three-month notice starting in early 2027.
From the perspective of a comparative financial analysis of SpaceX’s quarterly disclosures and Anthropic’s S-1 IPO model based on reports from Bloomberg, Yahoo Finance, and CNBC, the exceptional nature of this business relationship becomes clear, driving Superintelligence division revenue to $7.56 billion in the third quarter. Anthropic relies heavily on the Colossus cluster computers in Memphis to run and train its models, while maintaining contractual flexibility allowing it to terminate the agreement with just 90 days’ notice starting in early 2027.
As part of the comprehensive editorial review for the Friday, October 30, 2026 newsletter regarding the “SpaceX computing customers” file, journalistic auditing based on primary sources and documented news reports emphasizes the methodological necessity of distinguishing between officially announced financial and technical figures and future expectations or preliminary tests under evaluation. This ensures that the Arabic reader receives comprehensive, accurate professional coverage spanning all aspects of the event and its direct and indirect ramifications on the global artificial intelligence sector and the future of competition among major tech companies.
