- The prospectus now runs through September. Anthropic filed an amended Form S-1 with the Securities and Exchange Commission on Monday, adding third-quarter results to a filing that previously covered only the first half. Revenue for the nine months ended Sept. 30 reached $33.24 billion, up roughly 1,200% from a year earlier, with about $17 billion of that coming in the third quarter.
- Growth is slowing and the operating line flipped. Third-quarter revenue growth slowed to 47% from 144% in the second quarter, and the company swung to a $567 million operating loss from a $974 million operating profit in the prior quarter, according to CoinDesk. Anthropic blamed the loss mainly on $5 billion of computing capacity bought through costlier short-term commitments and $2 billion in noncash charges tied to its donation-matching program, while price cuts and contractual discounts trimmed revenue by about $600 million.
- The headline net loss is mostly accounting. Anthropic reported a $23.29 billion net loss for the quarter, largely driven by a $21.9 billion charge from revaluing convertible notes and related instruments as its enterprise valuation rose. For the nine months, the net loss was $104 billion versus $25.1 billion a year earlier, with most of the increase tied to changes in the fair value of convertible notes and derivative liabilities.
- The compute bill is enormous. The company disclosed purchase commitments and lease agreements with an aggregate committed spend of about $895.4 billion, “substantially all of which is related to compute and infrastructure,” with about $69.8 billion due within 12 months of Sept. 30. Compute and infrastructure expenses rose by $14.4 billion, or 329%, in the first nine months of the year.
What Happened?
Anthropic published its amended S-1 on Monday, giving investors their first look at third-quarter numbers ahead of a potentially historic initial public offering. The company filed to go public on Oct. 26, with pricing expected in mid-November, according to CoinDesk. Anthropic gets much of its capacity from Amazon, Google and SpaceX but also relies on neoclouds for some compute. The filing includes more than 90 pages of risk factors, covering potential political headwinds, complex infrastructure needs and the difficulty of balancing safety with commercial objectives.
Why It Matters?
The update lands just as the market questions the economics of the AI buildout. Wall Street has worried that rising interest rates will make debt unaffordable for many data center developers and neoclouds, and last week’s quarterly reports from Microsoft, Google and Amazon showed aggressive AI spending eating into cash flows, according to CNBC. Anthropic’s own numbers show the same tension: demand is large enough to push it into expensive short-term capacity, but that capacity is what turned an operating profit into a loss. A slowdown from 144% to 47% growth is still rapid expansion, yet it changes the valuation math for IPO buyers who will be paying for future growth and committing alongside nearly $900 billion of long-dated obligations.
What’s Next?
The road show is next, and investors will press management on how quickly it can replace short-term compute purchases with cheaper multiyear agreements and how much more pricing pressure lies ahead after the roughly $600 million hit from discounts. The $69.8 billion of commitments due within 12 months is a near-term cash test that IPO proceeds will help meet. Rival OpenAI confidentially filed its prospectus in June but has signaled it is aiming for a 2027 debut, so Anthropic’s reception will set the tone for AI listings.
