Anthropic lost $80.7bn in the first half of 2026, mostly on a $72bn accounting charge, Reuters reports from a draft prospectus

Anthropic's net loss widened to $80.7bn in the first half of 2026, from $13bn a year earlier, Reuters reported on 20 October from a draft IPO prospectus it reviewed. Most of the loss was a $72bn accounting charge tied to a rise in the estimated value of convertible bonds, which Reuters says is not a cash cost of running the business.

Reuters also reported that Anthropic spent nearly $9bn on computing capacity and infrastructure in the half, up from $2.3bn a year earlier, and that it has committed at least $518bn over a decade to cloud, computing and infrastructure. Second-quarter revenue more than doubled from the first quarter to $11.6bn, Reuters reported. The Wall Street Journal put first-half revenue at $16.3bn, according to Al Jazeera, which says the report could not be immediately verified.

Anthropic did not respond to Reuters. The pages describe a draft prospectus; the Switchboard found no public Anthropic registration statement on the SEC's EDGAR system, so none of these figures can be checked against a filing yet.

What changed: on 17 October the Switchboard ran Reuters' report of the prospectus figures for 2025, a $42bn loss on nearly $4.6bn of revenue. This adds the first half of 2026. Anthropic is expected to list in November, Reuters reported.
