Anthropic, the company that makes the Claude AI assistant, is now SpaceX's largest single customer, according to a person familiar with the matter who spoke to Bloomberg. A SpaceX filing lists an unnamed 'Customer B' that made up 34.5% of third-quarter revenue. That is more than a third of the quarter's sales.
What the filing shows
The filing does not name the customer. It only labels it 'Customer B.' The link to Anthropic comes from the source, not from a company statement. That share is also larger than the US government's, which is a major SpaceX customer.
Why it matters
The story hints at how much AI companies are spending to build and run their tools. Money at that scale can shape the prices and services of the products people use every day, including chat assistants like Claude.
What is not known yet
- What Anthropic is buying from SpaceX.
- How much money the 34.5% share represents.
- Whether Anthropic or SpaceX will confirm the report.
- How long the arrangement is meant to last.
The material available does not answer those questions. Until either company comments, the identity of Customer B rests on one unnamed source.
The takeawayA source says Anthropic is SpaceX's biggest customer at 34.5% of Q3 revenue, but neither company has confirmed it in the material available.
