On November 10, Anthropic announced the launch of its IPO roadshow. It plans to offer 825 million Class A shares, about 801 million from the company and about 23.65 million from existing stockholders, at an expected $70 to $78 per share, and to list on the Nasdaq Global Select Market as ANT. S-1 Amendment No. 2, filed the same day, shows AMD, Broadcom, Google, Micron, Microsoft, NVIDIA, and TSMC buying a combined $26 billion of Class N stock at the IPO price. At the $74 midpoint, the company expects net proceeds of about $84.6 billion.
Key Takeaways
- ✓Size: 825 million Class A shares, 801,351,354 from the company and 23,648,646 from selling stockholders, plus a 30-day underwriter option for up to 123.75 million more (official announcement)
- ✓Price range: $70 to $78 per share, ticker ANT on the Nasdaq Global Select Market; Goldman Sachs and Morgan Stanley lead a 23-bank syndicate
- ✓Concurrent $26 billion private placement (at the $74 midpoint): about $10 billion each from Google and NVIDIA, $2.5 billion from AMD, $1 billion each from Broadcom, Micron, and Microsoft, and $500 million from TSMC, all buying Class N stock at the IPO price
- ✓Proceeds: about $84.6 billion net from the IPO and private placement at the $74 midpoint, or about $93.7 billion if the underwriter option is fully exercised; uses include compute and infrastructure (per the S-1/A)
- ✓Share count: about 13.087 billion shares of all classes after the offering; a rough calculation puts the price range at about $916 billion to $1.02 trillion in market value (our estimate, not an official valuation)

Core Background and Industry Pain Points
Anthropic publicly filed its S-1 on October 26 and added third-quarter financials in Amendment No. 1 on November 2, but the share count and price had not been set. Launching the roadshow with a price range on November 10 moves the IPO into the marketing phase with institutional investors. For developers, the company's compute spending and product pace will increasingly answer to public markets.
Architecture Highlights and Underlying Mechanisms
The IPO uses a multi-class structure. The public buys Class A shares. Strategic partners such as NVIDIA and Google buy Class N shares, which are not registered in this offering and are not covered by the underwriter lock-up. The S-1/A also states that Class F stock, held by the co-founders through a Founder LLC, carries 50.1% of the voting power, while the Long-Term Benefit Trust's Class T stock elects a majority of the board. Lock-ups generally run 180 days, and up to 365 days for co-founders and certain large holders.
Authoritative Benchmarks and Measured Comparisons
An IPO involves no model benchmarks, and no new model data was published. The comparable figure is the raise: at $70 to $78, the public offering is about $57.8 billion to $64.4 billion, plus the $26 billion private placement (our calculation from the announced share count). The prospectus estimates net proceeds of about $84.6 billion; all figures are company-reported.
Developer Adoption and Getting Started
The final price and listing date depend on the SEC declaring the registration effective, and nothing here is investment advice. The use of proceeds matters most: the prospectus lists compute and infrastructure. With NVIDIA, Google, AMD, TSMC, and other chip and cloud vendors becoming shareholders at the same time, Claude capacity, pricing, and multi-cloud supply may all be shaped by these ties.
