Anthropic is heading into its initial public offering with a target valuation of $1.4 trillion, according to its latest draft prospectus, in what Bloomberg described as a blockbuster debut that would rank among the largest stock market listings ever. The updated filing also reveals, for the first time, exactly how much money each of the company's seven co-founders stands to pocket when the shares begin trading.
The revised terms, reported by Reuters on Tuesday, show Anthropic aiming to raise as much as $64.4 billion in the offering. Reuters framed the listing as a test of Wall Street's AI fervor — a fitting description for a company that was valued in the private markets at a fraction of this figure only two years ago.

The Numbers Behind the Offering
The most eye-catching disclosure in the updated S-1 concerns the founders. Each of Anthropic's seven co-founders plans to sell 3,378,378 shares in the IPO, TechCrunch reported on Tuesday, based on the new filing. Shares are being marketed in an unusually broad initial range of $70 to $78.
At the $74 midpoint of that range, each founder would take in just shy of $250 million. At the bottom of the band, each would clear just over $236 million; at the top, just under $264 million. And in an offering generating this much attention, companies frequently price above the initial range, which would push those figures higher.
The seven sellers are the company's entire founding group: CEO Dario Amodei; president and board chair Daniela Amodei, who is also his sister; chief compute officer Tom Brown; head of public benefit Jack Clark; chief science officer Jared Kaplan; chief architect Sam McCandlish; and interpretability research lead Christopher Olah.
Who Else Is Buying
Two board members have already signaled personal interest in the offering, according to TechCrunch. Reed Hastings, the Netflix co-founder, has indicated he wants to purchase $300 million worth of shares through his donor-advised fund. Board member Christopher Liddell has also asked to buy $3 million worth of stock.
Those commitments are small relative to the overall raise, but insiders buying into the deal they oversee is traditionally read as a vote of confidence in the company's prospects after listing.
Control Stays With the Founders
After the sale, each founder will still own roughly 3.2 percent of Anthropic's outstanding Class A shares — about 22 percent collectively. That figure understates their economic stake, because other holders, including Amazon and Google, own nonvoting Class N shares that sit outside the Class A pool.
More importantly, the founders are not giving up control. Each will receive one share of a special Class F stock carrying supervoting rights, and collectively the seven will control 51.1 percent of the company's votes, according to the filing. No single founder holds meaningfully more shares or votes than the others — an unusual power-sharing arrangement for a company about to trade at this scale.
A Step Down From Earlier Ambitions
The $1.4 trillion target nonetheless represents a retreat from the numbers that circulated earlier in the process. As recently as September, the Financial Times reported that a $2 trillion valuation was under discussion as the company approached its Nasdaq debut, and reporting in August pointed to a possible raise of as much as $100 billion. The latest draft's $64.4 billion ceiling and $1.4 trillion valuation suggest the company and its bankers have calibrated expectations as they gauged institutional demand.
Even at the reduced scale, the offering would dwarf nearly every technology IPO in history. The sequencing matters for the wider AI sector too: Anthropic's debut is the most closely watched of the AI lab listings, and its opening-day performance will be taken as a referendum on how public markets value frontier model developers.
Separately, Yahoo Finance reported this week that Anthropic says a key AI safety alarm has been triggered just days before its IPO — a reminder that the company's safety commitments, a core part of its pitch to investors, remain under active scrutiny.
The Roadshow Is Already Under Way
The listing appears imminent. A retail roadshow presentation has already been published on NetRoadshow, the platform commonly used to market IPOs to investors, with links to the presentation circulating on Hacker News this week. Retail participation guides from brokers such as Fidelity have also appeared, underscoring how broad the expected demand is.
From OpenAI Breakaway to Record Debut
The seven founders left OpenAI together in 2021 after disagreeing with its leadership over how AI should be built, and they established Anthropic around an explicitly safety-focused approach to developing frontier models. Five years on, that breakaway has produced a company poised to list at $1.4 trillion — a figure that would place it among the most valuable companies in the world on its first day of trading.
What to Watch
Investors will be looking at three things when the stock starts trading: whether final pricing lands above the $70-to-$78 range, a sign of excess demand; how the stock performs against the private-market valuations that preceded it; and whether the founders' supervoting structure draws pushback from governance-minded funds. For the AI industry at large, the answer to all three will shape how the next generation of AI companies approaches going public.
