Anthropic kicked off the roadshow for its initial public offering on Tuesday, seeking to raise as much as $64.4 billion in a historic market debut that could value the creator of the Claude chatbot at up to $1.4 trillion.
The proposed offering ranks among the largest stock market debuts ever. It arrives at a critical juncture for Wall Street, where initial fervor over generative artificial intelligence (AI) is giving way to sharper scrutiny regarding the massive infrastructure spending required to develop frontier models.
According to regulatory filings, Anthropic and several existing shareholders plan to offer 825 million shares priced in an indicative range of $70 to $78 per share. Based on basic outstanding shares, the listing targets a valuation of roughly $1.02 trillion, while fully diluted figures — accounting for additional securities and stock options — push the upper bound toward $1.4 trillion.
The transaction is further augmented by a parallel private placement. Anthropic plans to raise $26 billion in separate investments from a group including Alphabet Inc.’s Google and NVIDIA Corp., contingent on the closing of the public listing. Together, the combined deals could generate up to $90.4 billion in gross proceeds, though a portion will be distributed to selling shareholders.
Founded in 2021 by former OpenAI researchers and led by CEO Dario Amodei, the San Francisco-based company has experienced explosive commercial traction. Filings show annualized revenue reached approximately $81 billion as of Oct. 31, driven by enterprise adoption across the healthcare and finance sectors.
However, that rapid ascent carries unprecedented financial overhead. Anthropic has secured nearly $900 billion in multi-year computing commitments with key infrastructure partners, including Amazon.com Inc. and Google.
Market expectations have moderated accordingly; prior private discussions had pegged the company’s valuation as high as $2 trillion before concerns mounted over tech stock volatility and heavy capital expenditure.
“What we are seeing is essentially a reassessment of Anthropic’s value in a more challenging AI environment,” said Ipek Ozkardeskaya, senior analyst at Swissquote Bank. “The company continues to post impressive growth, but investors are increasingly focused on the cost of generating that growth. The shift from a $2 trillion valuation reflects a change in focus from revenue growth alone to the significant financial commitments and spending required to sustain it.”
Despite broader sector headwinds, market observers view the pricing targets as a sign of underlying institutional confidence.
“In our view, a $1 trillion Anthropic that prices and trades well validates the capex that every name in the AI supply chain is being underwritten on and the cloud growth the hyperscalers just reported,” Wall Street analyst Dan Ives said in a note Tuesday.
“Given the volatility and concerns towards AI that we’ve seen, this is actually fairly bullish,” said Fiona Cincotta, senior market analyst at City Index in London. “It’s showing that they are still upbeat about the outlook as far as AI is concerned and that they think demand is going to be there.”
Anthropic plans to list on the Nasdaq Global Select Market under the ticker symbol “ANT,” where its performance will serve as a bellwether for the economics of the broader AI industry.
