Anthropic’s bankers prepare to raise its IPO valuation to $1.5 trillion or more

Anthropic’s bankers are preparing to increase the valuation in its initial public offering to $1.5 trillion or more^1,2. Tuesday’s filing implied a valuation range of $1.26 trillion to $1.41 trillion, calculated on a fully diluted basis that also accounts for employee stock options¹. The bankers are weighing the increase after that filing³.

The filing came as the company announced plans to raise as much as $64.4 billion in one of the largest IPOs in history¹¹. That target had fallen short of expectations, capping a week of political upheaval, financial turmoil and scandal for the AI industry¹¹.

Who gains

All seven of Anthropic’s founders will each sell about $250 million of stock in the offering^6,7, for a combined $1.75 billion⁵. The sales give the executives added liquidity⁵. The founders’ stakes are worth $18 billion apiece at the IPO price^3,4. Several hold senior roles: Kaplan is chief science officer, McCandlish is chief architect and Clark is head of the Anthropic Institute⁴. Besides chief executive Dario Amodei, the co-founders include Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish and Christopher Olah^5,7.

Amazon and Google are set for a big windfall⁸. The filing discloses other ties, including a $10.0 billion Google item that counts toward Google’s existing funding deal⁸. Nvidia planned to invest $10 billion in Anthropic alongside the IPO, the largest of the new financial commitments⁹. TSMC will invest up to $1 billion in Anthropic and OpenAI, including up to $500 million to acquire preferred stock in OpenAI¹⁰.

What to watch

The two sets of signals point in different directions. The initial target was seen as falling short of expectations¹¹, while the bankers are now preparing to raise the valuation¹. Where the price is finally set will show how much demand the roadshow has drawn.

The stakes reach beyond one company. The industry needs a strong showing from Anthropic to avoid a crisis of confidence after a difficult week, according to one assessment¹¹. The deal also ties Anthropic more closely to Nvidia⁹ and to TSMC¹⁰, and leaves Amazon and Google holding large stakes in a listed company⁸.
