Anthropic tells investors Q3 revenue was $16.8bn, up nearly 50% from Q2, ahead of a planned IPO, per FT

The Financial Times, citing anonymous sources, reports that Anthropic told investors at an event on Wednesday that its revenue was about $4.8bn in Q1, $11.5bn in Q2 and $16.8bn in Q3 2026, which is growth of nearly 50% on the previous quarter. In Q3 it reportedly earned $1.70 of revenue for every $1 spent on computing power, with an adjusted operating margin of 11% excluding stock-based compensation. Distillation by rival labs reportedly made up 5-7% of revenue, which Anthropic says it cut back materially in Q3. Anthropic appears to have stopped quoting annualised run-rate revenue in these communications. Nothing here comes from a filing or an Anthropic statement, and the story reaches us second-hand through a blog post summarising the FT.

If accurate, this is the clearest look yet at the economics of a frontier lab: very fast growth and a positive margin on an adjusted basis, just before a planned IPO. Investors, competitors and enterprise buyers can use it to judge how durable Anthropic is as a supplier and how much pricing power it has. The distillation figure is the most unusual detail, because it suggests rival labs were paying meaningful sums to use its models to train their own. The impact is still limited by the source: these are selected figures presented to investors, and the margin excludes stock-based compensation, which is typically a large cost at firms like this.

The headline growth figure is impressive but it is a company-chosen presentation, not audited accounts, and the "profitability" is an adjusted measure that leaves out a major cost. The apparent move away from run-rate revenue could mean many things, so reading it as a signal either way is speculation. Missing context includes total cash burn, how much revenue is one-off or concentrated in a few customers, and how the distillation revenue is defined.

1. 01The IPO filing (S-1 or equivalent), to check the quarterly revenue, the 11% adjusted margin and the $1.70 per $1 compute figure against audited numbers, including the stock-based compensation excluded here.
2. 02Any Anthropic confirmation, denial or correction of the FT figures, and whether other outlets with their own sources report the same numbers.
3. 03Q4 2026 revenue and how the distillation share evolves, plus whether Anthropic or rival labs change terms of service or enforcement, which would show whether the cut in distillation revenue is real and lasting.
