San Francisco, November 10, 2026: Artificial intelligence company Anthropic, the developer of the Claude AI assistant, has announced plans to raise as much as $90.4 billion through an initial public offering (IPO) and a separate private placement, marking one of the largest proposed fundraising exercises in stock market history.
According to documents filed with the US Securities and Exchange Commission (SEC) on Tuesday, the company plans to offer 825 million shares at an indicative price of $70 to $78 each.
The public offering could raise approximately $64.4 billion, while a separate $26 billion private placement involving major technology companies would bring the combined amount to approximately $90.4 billion.
The announcement comes as investors increasingly examine whether the rapid growth of artificial intelligence can justify the industry’s enormous infrastructure spending.
Anthropic Launches IPO Roadshow
Anthropic officially launched the marketing process for its proposed public offering on November 10.
The company plans to list its Class A common shares on the Nasdaq Global Select Market under the proposed ticker symbol ANT.
According to its SEC filing, Anthropic will offer approximately 801.35 million newly issued shares, while existing shareholders will sell another 23.65 million shares.
The company will receive proceeds from the newly issued shares but not from shares sold by existing investors.
The offering remains subject to regulatory requirements, and the final share price has not yet been determined.

The combined fundraising amount includes both the public share offering and investments through the separate private placement.
Google, Nvidia and Microsoft Among Major Investors
Anthropic has secured agreements involving several prominent technology companies for its planned $26 billion private placement.
The participating companies include Alphabet’s Google, Nvidia, Microsoft, Advanced Micro Devices (AMD), Broadcom, Micron Technology and Taiwan Semiconductor Manufacturing Company (TSMC).
These investments reflect the close financial and technological relationships developing across the artificial intelligence industry.
Major technology companies are increasingly investing in AI developers while also supplying the computing infrastructure required to train and operate advanced models.
The planned private placement will occur alongside the public offering, subject to the relevant transaction conditions.
Anthropic’s IPO Could Become One of the Largest Ever
If completed at the proposed maximum amount, Anthropic’s public offering would rank among the largest IPOs in global financial history.
The deal would also represent a major milestone for the generative AI sector.
Anthropic is among the prominent developers of advanced AI models, competing in a market that includes OpenAI, Google and other technology companies.
A successful stock market debut would give public investors direct exposure to one of the leading companies developing frontier artificial intelligence systems.
However, the final size of the offering will depend on pricing and investor demand.
Claude AI Drives Anthropic’s Business Expansion
Anthropic develops the Claude family of artificial intelligence models, which are used for writing, software development, research, data analysis and enterprise applications.
The company has expanded its services to businesses through subscription products and API access.
Enterprise adoption has become an important part of its commercial strategy.
Anthropic competes for customers seeking advanced AI capabilities while emphasising model reliability, safety and performance.
The company has also invested heavily in improving the capabilities of its AI systems.
Revenue Growth Attracts Investor Attention
Anthropic’s financial performance has become a central focus ahead of its proposed listing.
According to Reuters, the company’s annualised revenue run rate reached approximately $81 billion as of October 31, 2026.
This represents a substantial increase in business activity as demand for enterprise AI services continues to expand.
However, an annualised revenue run rate is not the same as revenue already earned over a completed financial year.
Investors will also examine profitability, operating expenses and the sustainability of growth.
The company continues to face significant costs associated with developing and operating advanced AI systems.
AI Infrastructure Spending Raises Concerns
Despite strong revenue growth, Anthropic’s capital requirements remain substantial.
Training advanced AI models requires specialised processors, large data centres, electricity and sophisticated computing systems.
The company has disclosed extensive commitments related to future computing capacity.
These investments are necessary for expanding AI services but create financial risks if revenue growth fails to keep pace with expenditure.
Investors are increasingly assessing whether AI companies can generate sufficient long-term returns to justify their infrastructure commitments.
Anthropic IPO Valuation Draws Market Attention
The offering is expected to place Anthropic among the world’s most valuable technology companies.
However, market reports have highlighted changing valuation expectations as investors reassess the costs and profitability of AI development.
Earlier discussions involved significantly higher potential valuations.
The latest proposed share price range provides a clearer basis for evaluating the company, although the final market valuation will depend on the offering structure and pricing.
Investors will examine the company’s revenue, losses, competitive position and governance arrangements before making investment decisions.
What Happens Next for Anthropic?
Following the launch of its IPO roadshow, Anthropic will market the proposed offering to institutional and other eligible investors.
The company and its underwriting banks will assess demand before determining the final offer price.
The SEC registration statement must become effective before shares can be sold under the offering.
The company has not yet completed its stock market debut.
The proposed Nasdaq listing will proceed only after the applicable requirements are satisfied.
Anthropic IPO Marks Major Moment for AI Industry
Anthropic’s proposed $90.4 billion combined fundraising represents an important development in the commercial growth of artificial intelligence.
With $64.4 billion targeted through its IPO and $26 billion through a separate private placement, the company is seeking substantial capital to support its expansion.
The participation of major technology companies highlights the scale of investment flowing into the AI sector.
However, the offering also comes amid growing scrutiny of infrastructure spending, profitability and long-term financial returns.
The outcome of Anthropic’s public listing could influence investor sentiment towards other major AI developers and the wider technology industry.
