The Anthropic IPO is officially the biggest test yet of Wall Street’s faith in the AI boom — and the Claude maker just put a staggering number on it.

Anthropic, the company behind the Claude chatbot, set a price range of $70 to $78 per share in an updated SEC filing on Tuesday, Nov. 10, 2026. At the top of that range, the company would be valued at up to $1.404 trillion on a fully diluted basis — about $1 trillion counting only shares outstanding. That would make it the biggest AI-industry debut ever, and one of the largest IPOs in history.

It is a moment the entire tech world has been waiting for. For years, the AI race has been fought with private money, eye-watering valuations and promises of a future payoff. Now Anthropic is asking the public markets to put a price on it — in public, in real time, with real money on the line.

The numbers behind the $1.4 trillion tag

Anthropic plans to sell 825 million Class A shares, raising between $57.75 billion and $64.35 billion, depending on where the final price lands in the $70-to-$78 range. Pricing is expected Nov. 18, with trading expected to begin Nov. 19 on the Nasdaq under the ticker “ANT.”

Up to 20% of the offering is allocated to retail investors, giving everyday investors a direct shot at a piece of the debut — a rare move for an offering of this size, and a sign of just how much demand Anthropic expects.

Each of Anthropic’s seven co-founders plans to sell 3,378,378 shares in the offering, cashing in a slice of the company they built while keeping the bulk of their stakes for what comes next.

Big Tech is buying in — literally

Alongside the listing, Anthropic agreed to privately sell $26 billion of non-voting stock at the IPO price to AMD, Broadcom, Google, Micron, Microsoft, Nvidia and TSMC — with Google and Nvidia each investing $10 billion.

Read that list again. Those are not just investors. They are the companies that make the chips, run the clouds and build the hardware the AI boom runs on. When your suppliers, your customers and your biggest rivals all want a piece of your IPO at the same price the public pays, that is Wall Street’s version of a standing ovation.

It also tells you how high the stakes have become. The AI race is no longer just about who has the smartest chatbot. It is about compute, partnerships and scale — and Anthropic is locking in all three before its first day of trading.

Claude is printing money — by AI standards

The filing gives investors something the AI hype cycle has not always delivered: actual revenue, growing fast. Run-rate revenue reached about $81 billion by the end of October, up about $10 billion from the end of September alone. Third-quarter revenue was about $17 billion, up from about $1.4 billion a year earlier.

That is the kind of growth curve that makes even seasoned investors do a double take. Claude has expanded from a chatbot into the workplace, powering coding, research, writing and business workflows for companies that are now paying serious money for it. As The AI Insider reports, Claude’s push into the workplace is central to the company’s pitch to investors.

The question for the market is no longer whether people will pay for AI. It is whether Anthropic can keep growing fast enough — and profitably enough — to justify a valuation with twelve zeroes in it.

Still not SpaceX — yet

For all the superlatives, the $1.4 trillion top is below the $2 trillion valuation talked about in October, and it sits well above the $965 billion valuation from Anthropic’s May funding round. The Financial Times reports bankers are weighing a higher price that could lift the valuation to $1.5 trillion or more — Anthropic has not confirmed that.

And for scale, there is still one debut bigger than this one. SpaceX’s June IPO raised $86.25 billion at a $1.77 trillion valuation, the largest IPO in history. Anthropic would not top that — but as TipRanks notes, it would still be the biggest AI-industry debut ever, and the gap between the two says a lot about where the money — and the momentum — is heading.

SpaceX proved that a trillion-dollar-plus IPO can work. Anthropic is about to find out whether the same is true for AI.

What happens next

All eyes are now on Nov. 18, when the final price is set, and Nov. 19, when ANT starts trading. If demand is as strong as the filing suggests, the price could land at the top of the range — or, if the bankers get their way, even higher.

If it stumbles, it will not just be Anthropic’s problem. Every AI startup, every chipmaker and every investor who has bet the house on artificial intelligence will feel it. This IPO is the moment the AI boom stops being a private-market story and becomes a public-market verdict.

Either way, Nov. 19 is shaping up to be one of the most-watched trading days in years. The Claude maker is going public, the price tag is $1.4 trillion, and Wall Street is about to tell us what it really thinks AI is worth.
