- Anthropic submitted its S-1 paperwork on October 26, targeting a Nasdaq listing under ticker ANT.
- First-half revenue hit $16.3 billion through June 30, surging from $1.16 billion year-over-year.
- A single-share structure guarantees its seven co-founders 50.1% of all voting power.
Seven co-founders will retain majority voting authority over Anthropic using just one share. This unique setup highlights the S-1 filing with the US regulator on October 26 for its planned Nasdaq float under ticker ANT.
In the first six months ending June 30, Anthropic generated $16.3 billion in revenue, up from $1.16 billion in the prior period. Second-quarter operating profits reached $974 million on $11.6 billion of revenue.
The registration document omits the price range, total compute commitments, and third-quarter revenue numbers. Goldman Sachs and Morgan Stanley head an underwriting syndicate featuring 22 institutions.
Reports indicate the business is targeting a mid-November listing week, seeking to raise $100 billion and potentially reach a valuation of $1.5T to $2T. Official filings omitted specific valuation metrics.
A profitable quarter inside an $80.7B loss
Paper adjustments accounted for most recorded losses. S-1 details reveal $72.4 billion derived from non-cash valuation markdowns on convertible notes, which gain value alongside Anthropic’s rising valuation.
Another $8.8 billion in expense stemmed from agreements under which Google and Amazon purchased Series G-2 stock at $259.14 per share, compared with Series H pricing at $589.01. On an adjusted basis, net income for the half reached $2.7 billion.
Top-line performance for the half-year surged to $4.6 billion, up from $386 million in 2024 and $41 million in 2023. Model versions released in the prior six months accounted for over 80% of Q3 earnings.
Compute and infrastructure expenses dropped from 251% of revenue in Q1 2025 to 48% by Q2 2026, though management notes margins will fluctuate with the timing of compute deliveries purchased 12 to 18 months in advance. At June 30, cash balances and short-term holdings stood at $112.4 billion and $19.3 billion, respectively.
Key operational vulnerabilities were also outlined. Over 11,900 enterprise clients spent $100,000 or more over the trailing twelve months, up from roughly 950 a year earlier, with net revenue retention around 900%.
No single customer accounted for more than 10% of revenue in the first nine months of 2026, with the top five together generating about 25%. However, cloud partner channels, including Amazon, Google, and Microsoft, accounted for 48% of first-half income, despite offering competing models.
“Anthropic filing a confidential S-1 starts the clock on what will be the most scrutinized public offering in tech history, and the number that determines everything is gross margin. It will either validate or collapse the entire narrative the private markets have been pricing for three years. While conventional reading suggests Anthropic seized the narrative advantage by filing first, OpenAI now holds a free option to observe how institutional investors react to audited frontier AI financials before committing to its own price,” said Harrison Rolfes, senior late-stage research analyst at PitchBook.
Seven founders, one share
Dario Amodei directed research at OpenAI before establishing Anthropic alongside sister Daniela Amodei in January 2021. She previously oversaw safety and policy initiatives at OpenAI.
Co-founders also include Tom Brown, chief compute officer; Jack Clark, leading the Anthropic Institute; Jared Kaplan, chief science officer; Sam McCandlish, chief architect; and Christopher Olah, head of interpretability research. A joint letter emphasises their conviction that artificial intelligence represents an unprecedented human milestone.
Founder LLC holds a single Class F instrument that secures 50.1% voting control over general governance matters, excluding board seats assigned to the Long Term Benefit Trust. That trust, guided by five independent trustees, holds Class T shares that grant majority board oversight.
Dilution mechanisms are also built in. Anthropic granted 846,840,960 Class N shares, representing 5% of fully diluted shares, to the Anthropic Public Benefit Fund, with the board authorized to add up to 2% more each time the stock rises 50% past its previous milestone.
The public offering also triggers a $2.9 billion catch-up charge on RSUs, with an additional $23.7 billion recognized over approximately 2.1 years.
Institutional backing remains strong. A Series H transaction closed May 28, securing $65B at a $965B valuation, led by Altimeter, Dragoneer, Greenoaks, and Sequoia. Tech Funding News previously highlighted early raising efforts targeting $350 billion, which eventually expanded to $380 billion in February.
Landlords, rivals, and a compute bill in the hundreds of billions
Anthropic maintains extensive infrastructure commitments with direct market competitors that also serve as lenders.
Signed leases that have not yet commenced carry roughly $321.4 billion in payments, alongside $265.6 billion in fixed purchase commitments. Named infrastructure vendor commitments include at least $114.5 billion with Google, $110 billion with Amazon, and $44.9 billion with Microsoft.
Google, Amazon, and Broadcom also provide $77 billion in undrawn note facilities, with Broadcom providing $161.2 billion in equipment leases restricted to paying rent on its own infrastructure. Additionally, AMD has agreed to purchase up to $5 billion in stock as it delivers GPUs.
SpaceX, following its public market debut in June, is another core compute vendor, with commitments up to $120.5 billion. Meanwhile, London-based Nscale revealed in its regulatory filings commercial agreements reaching $44.6 billion, finalized August 25.
Investor interest is strong, yet the filing’s structural realities raise significant long-term considerations. With 50.1% voting authority firmly locked in the hands of the seven founders and hundreds of billions committed to long-term compute leases, Anthropic’s public debut will serve as a critical benchmark for how public markets price frontier AI economics and unconventional governance structures.
