Anthropic sets IPO price range of $70 to $78, looks to start trading Nov

Anthropic has set a price range of $70 to $78 per share for its upcoming initial public offering, filing to sell 825 million shares on the Nasdaq under the ticker symbol "ANT." According to CNBC's report, the five-year-old AI lab is planning to price on November 18 and begin trading on November 19, putting one of Silicon Valley's most closely watched debuts within days.

This article covers the full terms of the offering, the market environment Anthropic is navigating, the chip and cloud partnerships backing the deal, the company's financial trajectory, and the new Claude models released days before the roadshow — information relevant to any investor, enterprise customer, or observer of the AI industry.

01$64.35 billion in proceeds at the high end

At $78 per share, Anthropic's IPO would generate up to $64.35 billion in net proceeds. On a fully diluted basis, the company could be valued at as much as $1.405 trillion, a significant jump from the $965 billion valuation Anthropic announced when it raised a funding round in May. That progression — from $965 billion to a potential $1.4 trillion in roughly six months — reflects the pace at which the company's revenue has grown.

Anthropic is targeting retail allocation of roughly 20% of the offering, far above the 5% to 10% that is typical for most IPOs. The company's order book is already covered at the $70 to $78 range on an allocable basis, according to people familiar with the process, and institutional demand is described as stronger than it was for SpaceX at the equivalent stage.

02A $26 billion private placement with seven firms

Alongside the public offering, Anthropic has entered a private placement agreement with Advanced Micro Devices, Broadcom, Google, Micron, Microsoft, Nvidia, and Taiwan Semiconductor Manufacturing Co. Each firm will purchase Class N common stock at a price equal to the IPO price, for a combined $26 billion. The shares sold through the private placement will not be registered as part of the public offering and will not be subject to lock-up agreements with the underwriters.

The arrangement effectively ties seven of the largest names in semiconductors and cloud infrastructure directly to Anthropic's post-IPO stock price. For Anthropic, it also diversifies its capitalization table with strategic partners who already supply or consume significant AI compute — a signal the company is embedding itself into the infrastructure stack rather than sitting above it.

03Political headwinds and a skeptical public market

Anthropic executives are heading into the roadshow against a complicated backdrop. Last week's midterm elections produced a Democratic sweep in Congress and the passage of several statewide ballot measures that analysts say could slow the AI buildout. Rising interest rates have simultaneously made public market investors more cautious about AI companies that require expensive infrastructure and debt to scale.

Some Anthropic investors had been expecting a valuation closer to $2 trillion before market sentiment shifted. Shareholders told CNBC that even $1.5 trillion is now in question, with one investor characterizing that figure as "a stretch." The IPO range, implying a fully diluted cap of up to $1.405 trillion, reflects those recalibrated expectations rather than the highs floated earlier in the year.

04$33.24 billion in nine-month revenue, $81 billion run-rate

For the nine months ended September 30, Anthropic reported $33.24 billion in revenue, roughly 1,200% higher than the same period a year earlier. The company posted a $104 billion net loss over that stretch, though Anthropic said most of the loss was attributable to changes in the fair value of convertible notes and derivative liabilities rather than operating cash burn; the comparable net loss for the same nine months in 2025 was $25.1 billion.

By the end of October, Anthropic's run-rate revenue had reached approximately $81 billion, up $10 billion from the prior month. The company's amended S-1 also disclosed $895.4 billion in purchase commitments, underscoring the scale of enterprise demand for Claude-based products and services. Anthropic primarily sells to other businesses rather than directly to consumers.

05Claude Fable 5.2 and Mythos 5.2 launched ahead of trading

On the Monday before the price range filing, Anthropic released two new frontier models: Claude Fable 5.2 and Claude Mythos 5.2. The launch was notable because CEO Dario Amodei had publicly called in September for slowing the pace of AI development, making these the first frontier models Anthropic has shipped since that statement. The company said both models underwent rigorous safety and alignment testing, and that it developed new evaluations and post-launch monitoring tools specifically for this release.

Amodei co-founded Anthropic in 2021 after leaving OpenAI with a group of researchers; OpenAI is now Anthropic's primary rival. The prospectus includes a co-founders' letter stating: "Our aim is to help humankind chart a safe course through this technological evolution, open new frontiers of discovery, and bring forth an age of miracles." Should the November 19 trading date hold, Anthropic's debut would arrive roughly five months after SpaceX raised $85.7 billion in a record IPO; SpaceX currently carries a market cap of just under $2 trillion.
