Anthropic files S-1 for Nasdaq listing, showing $11.6B Q2 revenue

Anthropic has publicly filed an S-1 with the SEC for a Nasdaq listing under the ticker "ANT", with Goldman Sachs and Morgan Stanley leading the offering. According to The Decoder, the AI lab is the first major company of its kind to publicly file an S-1. Wall Street expects a valuation of roughly $2 trillion, per Yahoo Finance. That compares with Anthropic's most recent private valuation of about $965 billion, which already put it ahead of OpenAI at roughly $852 billion.

The revenue numbers are steep. Quarterly revenue went from $376 million in Q1 2025 to $11.6 billion in Q2 2026, which the article calls a 1,368 percent year-over-year increase. For the first half of 2026 Anthropic brought in $16.3 billion, more than triple its full-year 2025 revenue of $4.6 billion. In Q2 2026 it posted its first positive GAAP operating profit, at $974 million. Compute costs rose 300 percent over the same period, slower than revenue. Revenue per employee is $6.6 million, higher than any Magnificent 7 company except Nvidia, with about 5,300 people on staff. Government contracts are only about one percent of revenue, while roughly 5 to 7 percent comes from customers who violate usage policies, primarily through model distillation, which Anthropic has already been cracking down on. Chip stocks such as Nvidia, Broadcom and AMD rallied after the filing went public.

Existing customers are expanding fast. Net revenue retention is roughly 900 percent, which the article reads as existing customers spending nine times what they did a year ago. More than 11,900 customers pay over $100,000 a year and about 250 spend more than $10 million. No single customer is above ten percent of revenue, but five customers together make up 25 percent. Claude Enterprise users who also use Claude Code are the biggest spenders, paying about 20 times more than other customers, according to the S-1. Eighty percent of revenue is billed on actual usage, per token processed, and the other 20 percent comes from fixed subscriptions. The FT reports that the company's forecast for next year will be primarily usage-based.

The other side of the ledger is obligations. Compute capacity contracts with Broadcom, Google, Amazon, Microsoft and other providers add up to roughly $780 to $810 billion. The article says those costs are more or less fixed and locked in long-term, while revenue is variable and depends on usage. So Anthropic has to keep growing fast to cover its future bills, and if it cannot, the article warns, the AI-fueled capital market could start to wobble. To gain flexibility and lower costs over time, Anthropic is building its own data centers under the name "Anthropic Direct".

The filing leaves out Q3 numbers, even though the company already has them. The article offers one possible reason, that growth slowed significantly in Q3, but adds that momentum may have picked back up. OpenRouter data shows demand for Anthropic models climbing again after the October release of the 5.5 series, especially Opus 5.5. OpenRouter captures only a tiny slice of total token demand and skews toward open-weight models, so strength there suggests Anthropic is likely doing even better elsewhere.

Key facts

  • Anthropic filed an S-1 to list on the Nasdaq as "ANT", with Goldman Sachs and Morgan Stanley leading; Yahoo Finance says Wall Street expects a valuation of roughly $2 trillion, versus about $965 billion in the last private round.
  • Q2 2026 revenue was $11.6 billion and the first positive GAAP operating profit was $974 million; first-half 2026 revenue was $16.3 billion versus $4.6 billion for all of 2025.
  • Long-term compute commitments with Broadcom, Google, Amazon, Microsoft and others total roughly $780 to $810 billion, largely fixed while revenue is usage-dependent.
  • Net revenue retention is roughly 900 percent; 80 percent of revenue is billed per token and 20 percent is fixed subscriptions; five customers make up 25 percent of revenue.
  • The S-1 omits Q3 numbers even though the company has them; the article names slower Q3 growth as one possible reason.

Why it matters

This is the first time the financials of a frontier AI lab are laid out in a public SEC filing, and the article says Anthropic is the first major company of its kind to file one. The numbers put a figure on AI demand: $11.6 billion in a single quarter, a first GAAP operating profit, and compute costs growing at 300 percent against much faster revenue growth. The filing also shows the cost of that growth. Commitments of roughly $780 to $810 billion are fixed and long-term, while revenue moves with usage. The article's reading is that Anthropic must keep growing fast to pay for them, and that a stumble could unsettle the AI-fueled capital market. Chip stocks like Nvidia, Broadcom and AMD rallied once the filing went public.

Who it affects

Prospective investors are the obvious audience, with Goldman Sachs and Morgan Stanley leading the offering. The compute providers named in the filing, Broadcom, Google, Amazon and Microsoft, are on the other side of the commitments. Anthropic's customers appear too: more than 11,900 pay over $100,000 a year, about 250 spend over $10 million, and five together account for 25 percent of revenue. Rival OpenAI, valued at roughly $852 billion against Anthropic's roughly $965 billion in the article's comparison, is the benchmark. Anthropic's roughly 5,300 employees and the Anthropic Direct data center build are part of the picture as well.

How to use it

Read it as a set of figures to compare against later disclosures. The numbers worth tracking are the usage-based share of revenue (80 percent, with the next-year forecast expected to be primarily usage-based per the FT), the split between compute commitments and revenue, and the customer concentration at 25 percent for five customers. The article also points to what is missing, Q3 numbers, and to OpenRouter demand data for the 5.5 series, especially Opus 5.5, as an outside signal of momentum. The article does not give an offering size, share price or listing date.

How solid is it

The figures come from the S-1 as reported by The Decoder, which names no author. Some points are the article's own reading rather than filing content: the $2 trillion valuation is an expectation attributed to Yahoo Finance, the next-year forecast is attributed to the FT, and the Q3 explanation is speculation. One number does not reconcile: the article calls the rise from $376 million to $11.6 billion a 1,368 percent year-over-year increase, but those two endpoints imply roughly a 31x increase, and the article does not explain the gap. The OpenRouter signal is also weak by the article's own account, since it covers only a tiny slice of token demand and skews toward open-weight models.

Risks and caveats

The central risk is the mismatch between fixed commitments of roughly $780 to $810 billion and variable, usage-dependent revenue. Customer concentration is another: no one is above ten percent, but five customers make up 25 percent, and the article says that would become a risk if they include companies like Meta, Google or Microsoft that could switch to their own or cheaper models. About 5 to 7 percent of revenue comes from customers who violate usage policies, primarily through model distillation. The missing Q3 numbers leave open whether growth slowed. Anthropic Direct is meant to add flexibility and lower costs over time, but the article gives no detail on its scale.
