Anthropic Opens IPO Roadshow at $70-$78 a Share

By Amara Osei

Anthropic, PBC launched its IPO roadshow on November 10, 2026, seeking to list 825 million Class A shares on the Nasdaq Global Select Market under the symbol "ANT" at an expected $70.00 to $78.00 per share. The same day, the company filed Amendment No. 2 to its Form S-1 registration statement, which remains ineffective. At the midpoint of the range, the 801,351,354 shares offered by Anthropic itself would raise roughly $59.3 billion before fees.

The filing's most concrete figure sits in a concurrent private placement: seven companies have agreed, severally and not jointly, to purchase $26.0 billion of Class N common stock at the IPO price, contingent on completion of the offering. Three of the five companies named below are among those placement investors. The prospectus does not yet disclose how the remainder of the $26.0 billion divides among the other four.

For R&D managers, the amended S-1 amounts to a supply-chain map. It names who trains Claude, who fabricates the silicon, who supplies the memory, and who distributes the model. Each named company, conveniently, reported strong results this month.

What does the Amazon relationship reveal?

Amazon appears three times in the filing. AWS Trainium is listed among the chip families used to train and serve Claude. As of September 30, 2026, $6.2 billion of principal was outstanding under convertible notes issued to Amazon, of which $579.3 million converts into 276,827,518 Class N shares immediately before the offering closes — the maximum issuable without breaching a 12% ownership cap. Amazon's Q3 results, released October 29, showed net sales up 12% to $201.9 billion and AWS segment sales up 39% to $46.0 billion.

CEO Andy Jassy said: "Our AWS investment in functionality and infrastructure is working, with over 39% year-over-year revenue growth in Q3 ($184 billion revenue run rate) and projected revenue growth rates of over 40% both in 2027 and in 2028." Those projections are Amazon's own; the release also noted Bedrock added Claude Fable 5.1, Opus 5.5, Sonnet 5.5 and Haiku 5.5.

How does AMD's supply agreement work?

The most structurally interesting commitment involves AMD. In July 2026, Anthropic signed a hardware supply agreement for AMD-based Helios rack-scale systems. AMD committed to purchase up to $5.0 billion of Class N stock, drawable in increments only after specified GPU delivery and deployment milestones. Its $2.5 billion placement purchase at closing will satisfy part of that commitment. The equity, in other words, is tied to hardware actually shipping.

AMD's Q3 results, released November 3, showed revenue of $13.4 billion, net income of $2.4 billion, and Data Center segment revenue up 97% year over year. "We delivered a record quarter with revenue exceeding the high end of our guidance as Data Center segment sales nearly doubled year-over-year," said Dr. Lisa Su, AMD Chair and CEO. The release listed Anthropic among companies running workloads on the first Helios racks.

What do Micron and TSMC contribute?

The prospectus states that high-bandwidth memory, a key component in high-performance accelerators, is largely manufactured by three companies, Micron among them. Micron's placement purchase is approximately $1.0 billion. Its fiscal Q4 results, released September 30, showed quarterly revenue of $54.23 billion against $11.32 billion a year earlier — nearly a fivefold jump — and full-year fiscal 2026 revenue of $133.19 billion against $37.38 billion the prior year. On November 5, director Linnie M. Haynesworth announced her retirement from the board effective at the January 14, 2027 annual meeting.

TSMC Partners, Ltd., which the prospectus refers to as TSMC, is purchasing approximately $500 million. The filing concedes that the majority of the world's most advanced chip manufacturing capacity is concentrated in Taiwan, primarily at TSMC — a geographic risk stated plainly. On November 10, TSMC reported October revenue of approximately NT$586.89 billion, up 14.7% from September and 59.7% from October 2025. Its board approved a NT$9.0 per share Q3 cash dividend and capital appropriations of approximately US$40,926.70 million. CFO Wendell Huang cited "strong demand for our leading-edge process technologies."

Where does Snowflake fit?

Snowflake's role is distribution, not capital. The prospectus names it among the data platforms through which customers can adopt Claude, alongside systems integrators and consultants. Its fiscal Q2 2027 results, released September 2 for the quarter ended July 31, showed revenue of $1.55 billion, up 35%, product revenue of $1.49 billion, up 37%, and remaining performance obligations of $9.00 billion. At Snowflake Expedition on November 3, it announced updates to its CoCo coding agent and CoWork knowledge-work agent.

"AI agents are reshaping how companies operate, and the difference between agents that guess and agents that know comes down to data," said Christian Kleinerman, EVP of Product, Snowflake.

The filing shows one company woven through the entire AI build stack — cloud, compute, memory, fabrication and distribution. What it does not show, yet, is the price at which the market will fund that stack; the registration statement has not become effective, and the placement remains contingent on the offering closing.
