Two customers bring in about a fifth of Anthropic's sales

Two customers account for about a fifth of Anthropic's sales, according to a report in The Globe and Mail. Anthropic is the AI company behind the Claude chatbot. The detail matters because those big customers pay by how much they use the service, and they have no long-term contracts. That means they can walk away.

The numbers reported

Anthropic reportedly made $16.3 billion in the first half of 2026. It also reportedly lost $80.7 billion over the same period. That loss sounds shocking, but about $72 billion of it came from non-cash accounting charges. These are bookkeeping entries that lower reported results without money leaving the company. They are not cash spent.

Why concentration matters

When a few customers supply a large share of sales, losing one can hurt a lot. Contracts usually soften that risk because customers commit for a set time. Pay-as-you-go use offers no such cushion. A customer can cut back or switch providers quickly.

What is not known yet

The material does not name the two customers. It does not say how much each one pays, or how soon an IPO, meaning a first public sale of company shares, might happen. The full article was not available for this summary, so details beyond those highlights are unconfirmed.

For anyone who may buy shares in a big AI IPO, the lesson is simple. Look at how much sales depend on a few customers, and whether those customers are locked in or free to leave.
