Anthropic's $64.35 Billion IPO Faces a $1 Trillion Test

By Amara Osei

Anthropic is marketing 825 million shares at $70 to $78 each in an IPO that could raise $64.35 billion and value the company near $1 trillion.

The roadshow began Tuesday. Pricing is expected Wednesday, Nov. 18, followed by a planned Nasdaq debut on Nov. 19 under ticker ANT, in what could become the largest artificial intelligence IPO to date.

What will Anthropic raise at its debut?

The share sale comprises 801.4 million newly issued shares and 23.6 million shares offered by existing shareholders. At $78 per share, the deal could produce $64.35 billion, while the filing's disclosed share count puts the implied valuation near $1 trillion.

That valuation sits below the $1.5 trillion figure that circulated before a recent technology-stock selloff. The pricing suggests Anthropic has prioritized a successful debut and strong investor demand over extracting the highest possible valuation.

Yorkville Ives & Co. said in a Nov. 10 research note that pricing at roughly $1 trillion, with an option to move toward $1.2 trillion, “is the right move.” The firm added: “A deal of this size gets one shot at its debut, and making it digestible for the market matters more than the last turn of valuation.”

In plain terms, Anthropic is pricing the IPO for a market able to absorb the deal, not for the highest headline valuation.

Who is investing beside public shareholders?

Alongside the public offering, Anthropic is arranging a $26 billion private placement with Alphabet, Nvidia, Advanced Micro Devices, Broadcom, Micron Technology, Microsoft and Taiwan Semiconductor Manufacturing Co. The two fundraises could reach $90.4 billion.

The investors have commercial ties to Anthropic as chip suppliers, cloud providers and distribution partners, giving them stakes in the developer of Claude before public trading starts. Their infrastructure spending could also generate returns for them.

Varun Datta, venture capitalist and founder of Truth Ventures, said: “Google, Nvidia, AMD, Broadcom, Micron, Microsoft and TSMC have commercial interests in the technology Anthropic needs to expand, giving them potential benefits beyond the return on their shares.”

He added: “What’s unusual is having seven major technology companies investing at this scale, including businesses that compete with one another and could also supply Anthropic with the infrastructure it needs.”

Google and Microsoft sell cloud capacity, while Nvidia, AMD and Broadcom supply AI chips and related technology. Anthropic's continued expansion could generate billions in additional orders for those businesses, extending their potential returns beyond Anthropic's share price.

Datta said: “I’d want to examine whether the investments are tied to purchasing commitments, cloud contracts or preferential supply arrangements.” He added: “Those details matter because they would help establish how much of the capital raised is available for Anthropic to deploy independently, and how much could ultimately flow back to its investors through commercial spending.”

The private placement could finance Anthropic while directing purchasing power back to its investors.

Why did Anthropic trim its terms?

The startup's revised $70 to $78 range for 825 million shares is below an earlier filing sent briefly to banks, which proposed $70 to $80 for 866.7 million shares. Reuters reported that a company representative later called the filing's pricing details inaccurate; Anthropic did not respond to a request for comment.

The revision followed a technology-stock selloff that began Nov. 5, when the Nasdaq fell 5.5%, its worst day since April 2025. One cited concern was that Democrats' midterm gains could lead to tighter artificial intelligence regulation.

Michigan Senator-elect Abdul El-Sayed, who won on Nov. 3, campaigned on a plan that includes “pausing frontier AI development.” Harvard's Ash Center said that category covers Anthropic.

The lower terms leave less room for a failed launch amid a weaker market and rising policy risk.

Can Anthropic sustain a trillion-dollar valuation?

Anthropic's filing shows $16.96 billion in third-quarter revenue, a $567 million operating loss and $900.9 billion in infrastructure commitments. Those commitments offer chipmakers and cloud providers a multi-year demand signal, but they raise a harder question about whether revenue growth can become sustainable margins.

The central test is whether Anthropic can sustain rapid expansion while bringing computing costs under control. Its second-quarter operating profit and third-quarter loss present sharply different pictures of its earnings potential.

Google, Amazon.com and Microsoft count as backers, customers and computing suppliers, showing how tightly the artificial intelligence ecosystem has become.

The IPO follows SpaceX's large offering and comes ahead of OpenAI's expected public listing in 2027. It could set a benchmark for valuing private AI companies, though the longer test is whether Anthropic can sustain its valuation after initial trading enthusiasm fades.

SpaceX, whose shares are down more than 13% year to date after its IPO, illustrates the risk that a sharp decline in Anthropic's share price could challenge assumptions underpinning the broader AI investment boom.

A trillion-dollar opening would set a benchmark, not settle the question of lasting profitability.
