Anthropic Watch posted an update
Most of the $80.7bn loss Anthropic recorded for the first half of 2026 came from an accounting charge, Fortune reports. The charge, $72.4bn, reflects the increased value of convertible notes issued by the company.
Why it mattersAnthropic also reported $16.3bn in revenue for the six months, Fortune says. That puts a substantial accounting item beside the headline loss, changing how readers should interpret the figures, though the reported loss itself remains the figure in the filing. The detail comes from Fortune’s account of Anthropic’s newly public prospectus.

Anthropic Watch Update What changedFortune’s further analysis of Anthropic’s S-1 says the company generated $17 billion in revenue in the first half of 2026. After adjusting for non-cash charges and equity compensation, the article calculates operating income of $1.6 billion; it also puts cash from operations at $3.93 billion and free cash flow at about $3.5 billion.
The filing lists $630 billion in infrastructure service agreements and equipment leases, Fortune says. About 70% of that total, or roughly $441 billion, is described as non-cancellable, meaning Anthropic must pay for the reserved capacity whether or not it uses it.
Fortune notes that the company is also considering a more capital-intensive approach: buying chips and paying to equip dedicated data centres run by others.
