Anthropic files for Nasdaq IPO, reporting $16.29 billion in first-half revenue and an 85% gross margin
Anthropic's S-1 for a Nasdaq listing under the ticker ANT shows first-half 2026 revenue up about 14-fold to $16.29 billion and gross margin rising to 85%. It leaves unresolved points about slowing growth, very large compute commitments and founder control.

Reach: not measured yet
First-half 2026 revenue reached $16.29 billion. Gross margin rose from 12% to 85%, and usage-based billing made up about 80% of revenue. The $80.7 billion net loss is mostly a non-cash revaluation of convertible notes, about $72 billion. [1] [2] [3] [6]
Anthropic buys compute from Google, Amazon, Microsoft, and Nvidia through SpaceX. Analysts' totals for these commitments range from about $417 billion to $637 billion. Compute is contracted 12–18 months ahead, while customers pay as they go with no long-term lock-in. [1] [2] [3] [4] [7]
The filing shows growth and margins well above peers at their IPOs. The unproven implication is that margins could swing if demand softens while compute contracts stay locked in. The IPO price may also shape sentiment across AI stocks.
Executive brief
Anthropic's first-half 2026 revenue rose about 14-fold to $16.29 billion, and its gross margin went from 12% to 85% in a year. Against that, it has compute obligations of roughly $417 billion (CNBC, Motley Fool). The S-1 was filed October 26 for a Nasdaq listing under the ticker ANT. It leaves several things open: why growth slowed (about 144% quarter-on-quarter in Q2, then about 47% in Q3), how compute splits between training and serving, how investors will take founder control with no sunset, and what the valuation will be. Analysts estimate $1–2 trillion.
What changed and event timeline
$965B private round
Anthropic raised $65 billion at a $965 billion valuation. The S-1 discloses this alongside earlier strategic investments from Microsoft and Amazon ().
Q3 figures shown to investors
The Financial Times reported $16.8 billion in Q3 revenue, up 45% from $11.6 billion, with an 11% adjusted operating margin. These were private, unaudited figures ().
Analysts list unanswered questions
Morningstar, Futurum and Leverage Shares pointed to the growth slowdown, how compute is allocated, governance and pricing as the gaps in the filing ().
Margin warning highlighted
Motley Fool noted that compute is contracted 12–18 months ahead, so spending is locked in while revenue is not ().
Capabilities and access
- The filing covers business performance, not model benchmarks.
- Usage-based billing (consumption revenue) made up $13.1 billion, or 80%, of H1 revenue (summary of the S-1).
- More than 11,900 customers spend over $100K a year, and more than 250 spend over $10M (CNBC live updates).

- The filing covers business performance, not model benchmarks. According to CNBC's summary it names Claude, Claude Code, "Claude Mythos 5" and "Claude Fable 5" (CNBC live updates).
- Usage-based billing (consumption revenue) made up $13.1 billion, or 80%, of H1 revenue (summary of the S-1).
- More than 11,900 customers spend over $100K a year, and more than 250 spend over $10M (CNBC live updates).
Technical analysis for researchers and developers
- Disclosed obligations include Google TPUs ($114.5B through 2033), Amazon ($110B through 2036), Microsoft ($44.9B through 2033) and Nvidia GPUs through SpaceX ($120.5B, about $3.1B a month, through 2029) (CNBC live updates).
- Cost structure. The filing says "substantially all" cost of revenue is compute and infrastructure.
- Starting in FY2025, Anthropic reports expenses by type of cost rather than by business function. That makes comparisons with earlier years difficult (Tunguz).

- Compute stack. Anthropic buys compute from several providers. Disclosed obligations include Google TPUs ($114.5B through 2033), Amazon ($110B through 2036), Microsoft ($44.9B through 2033) and Nvidia GPUs through SpaceX ($120.5B, about $3.1B a month, through 2029) (CNBC live updates). That spread reduces dependence on any one vendor but means models must run on several kinds of hardware.
- Cost structure. The filing says "substantially all" cost of revenue is compute and infrastructure. It does not separate compute used for training from compute used for serving customers (CNBC).
- Comparability. Starting in FY2025, Anthropic reports expenses by type of cost rather than by business function. That makes comparisons with earlier years difficult (Tunguz).
- Supply limits. Anthropic says it has historically been short of compute and asked cloud partners for more capacity than they would provide (CNBC).
Claims and evidence
- H1 revenue $16.29B, cost of revenue $2.38B, 85% gross margin. These come from the S-1 (CNBC).
- It was 8% in Q2 2026 after $9.7B of R&D spending (Motley Fool).
- Q3 figures. Anthropic has not said what the adjusted measure leaves out (Implicator).

- H1 revenue $16.29B, cost of revenue $2.38B, 85% gross margin. These come from the S-1 (CNBC).
- Operating margin. It was 8% in Q2 2026 after $9.7B of R&D spending (Motley Fool).
- Q3 figures. The $16.8B revenue, 11% adjusted margin and $1.70 of revenue per compute dollar came from investor presentations, not audited filings. Anthropic has not said what the adjusted measure leaves out (Implicator).
- H1 net loss of $80.7B. About $72B of this is a non-cash revaluation of convertible notes (CNBC live updates).
- Cash. Anthropic had about $112B in cash plus $19B in short-term investments at the end of June (Finimize). That pre-IPO cash pile is unmatched among companies going public, according to CNBC (CNBC).
Context and prior work
- Anthropic set up the Long-Term Benefit Trust in 2023. Through Class T stock it elects and removes a majority of the board (Anthropic).
- The S-1 adds a Founder LLC with 50.1% of the vote, held through a non-economic Class F share.
- Tunguz finds Anthropic's growth and gross margin well above peers at their IPOs, including OpenAI's reported growth (Tunguz).

- The S-1 adds a Founder LLC with 50.1% of the vote, held through a non-economic Class F share. Anthropic describes this setup as having "no direct public company precedent" (Motley Fool).
- Tunguz finds Anthropic's growth and gross margin well above peers at their IPOs, including OpenAI's reported growth (Tunguz).
Limitations, safety and contested findings
- Commitment totals disagree: about $417B (Motley Fool), at least $518B (Implicator) and $637B, two-thirds non-cancelable (Tunguz).
- Q3 growth is reported as about 47% by CNBC and 45% by the FT.
- A possible tension (inference): $1.70 of revenue per compute dollar is far below what an 85% gross margin would suggest.

- Commitment totals disagree: about $417B (Motley Fool), at least $518B (Implicator) and $637B, two-thirds non-cancelable (Tunguz). The gap probably reflects whether forecasted capacity ($125–150B) is counted.
- Q3 growth is reported as about 47% by CNBC and 45% by the FT.
- A possible tension (inference): $1.70 of revenue per compute dollar is far below what an 85% gross margin would suggest. The likely explanation is that the first figure includes training compute and the second does not.
- Risk factors include being blacklisted by the Pentagon, data-center moratoriums in 16 states, concentration of chip supply at TSMC, child-safety lawsuits, and misuse of AI for weapons (CNBC live updates).
- Governance: there is no sunset clause, and the S-1 says the structure may make directors harder to replace (CNBC).
Business and practitioner implications
- Anthropic signs compute contracts 12–18 months ahead, while customers pay as they go with no long-term lock-in (Motley Fool).
- Because compute has historically been short, enterprises should plan for rate limits during periods of tight supply (CNBC).
- At $2 trillion the stock would trade at about 63 times annualized sales (Motley Fool). Public shareholders would have little control.

- Pricing. Anthropic signs compute contracts 12–18 months ahead, while customers pay as they go with no long-term lock-in (Motley Fool). If demand softens, pricing pressure or margin swings are plausible.
- Capacity. Because compute has historically been short, enterprises should plan for rate limits during periods of tight supply (CNBC).
- Investors. At $2 trillion the stock would trade at about 63 times annualized sales (Motley Fool). Public shareholders would have little control.
- Sector signal. CNBC expects the IPO price to shape sentiment across AI stocks (CNBC).
