Anthropic's amended S-1 shows $17B Q3 revenue and $895B in compute commitments

Revenue for the three months ended September 30 was $16.96 billion, up 1,127% from $1.38 billion a year earlier[1]. Against the second quarter's $11.56 billion, that is growth of about 47%, down from roughly 144% in Q2 and 132% in Q1[1][2]. For the first nine months of 2026, revenue reached $33.24 billion, up 1,206%[1].

Compute and infrastructure costs were $9.86 billion in the quarter, up 382% year over year, which Anthropic presents as evidence that revenue per dollar of compute is improving[1]. About 44% of nine-month revenue came through cloud marketplaces run by its cloud partners[1].

The net loss for the quarter was $23.29 billion, and $104.04 billion for the nine months[1]. Most of that is accounting rather than cash: $94.32 billion of the nine-month figure is the change in fair value of convertible notes, derivative liabilities and SAFEs, which the filing says grows as the company's valuation grows[1]. The GAAP operating loss for the nine months was a much smaller $1.26 billion[1].

On its own adjusted measure, Anthropic reported $2.46 billion of operating income in Q3, a 15% adjusted operating margin, slightly below Q2's 19%[1].

The number drawing most attention is the forward spend. As of and after September 30, Anthropic says it has signed purchase commitments and leases with an aggregate committed spend of about $895.4 billion, "substantially all of which is related to compute and infrastructure"[1]. Around $447.5 billion of that is expected before the end of 2030[1]. The filing lists this among its risk factors, warning the commitments may substantially increase operating expenses and cash needs[1].

Anthropic has applied to list Class A common stock on the Nasdaq Global Select Market under the symbol "ANT"[1]. The share count and price range are still blank, so there is no valuation or date yet[1]. As a public benefit corporation whose Long-Term Benefit Trust holds the Class T shares and can elect a board majority, it will be a "controlled company" under Nasdaq rules[1].

These are the most detailed numbers yet from a frontier AI lab. They show a business adding about $5.4 billion of quarterly revenue in three months, and they also show what it is betting on: almost $900 billion of compute it has agreed to pay for. How the market prices that gap between today's revenue and tomorrow's commitments will shape how the rest of the AI buildout is financed[2].
