What happened

Anthropic reported $17 billion in revenue for the quarter ended Sept. 30 in an updated S-1 filing published Nov. 2. The first version of the filing, released a week earlier, had no third-quarter results. Revenue grew 47% from the prior quarter, against 144% growth the quarter before. A $5 billion hardware charge and a $2 billion donation-matching charge pushed the company to a $536 million operating loss, after $974 million of operating income in the second quarter.

What we know

SiliconANGLEsiliconangle.comBloomberg×3123
  • Revenue was $17 billion for the three months ended Sept. 30, more than 11 times the year-earlier figure, per SiliconANGLE's reading of the filing. Bloomberg described it as nearly $17 billion and a twelve-fold increase.
  • Quarter-over-quarter growth was 47%, down from 144% three months earlier, per SiliconANGLE.
  • Anthropic took a $5 billion charge because demand for computing hardware exceeded its plan and it had to buy at a premium on short notice. Its usual capacity commitments are booked 12 to 18 months ahead, per SiliconANGLE.
  • A separate $2 billion non-cash charge for an employee donation-matching program contributed to the $536 million operating loss. Adjusted operating income, which excludes stock-based compensation and charitable contributions, rose by $300 million to $2.5 billion, per SiliconANGLE.
  • Outstanding infrastructure commitments stood at $895.4 billion as of Sept. 30. Purchase commitments rose from $55 billion at the end of 2025 to about $314 billion, per SiliconANGLE.

What we don't know yet

  • How much Anthropic will raise in the offering has not been disclosed. SiliconANGLE cites Bloomberg saying the company hopes to at least match the $86.2 billion SpaceX raised, and Reuters saying it seeks a valuation of $1.5 trillion to $2 trillion. We could not see either original report.
  • Reports differ slightly on the year-on-year multiple: more than 11 times (SiliconANGLE) versus twelve-fold (Bloomberg). The S-1 text itself was not among our sources.
  • Whether the $5 billion premium-hardware charge is a one-off or a recurring cost of demand outrunning pre-booked capacity is unclear.
  • The filing says Anthropic is considering requiring human review and approval for some research tasks its models now perform automatically. Which tasks, and when, is not stated in the sources.

Why it matters

Prospective IPO investors are being asked to price a company whose growth rate fell by about two-thirds in one quarter while its commitments grew to $895.4 billion and its GAAP operating result turned negative.
