Anthropic Will Pitch Its IPO With a Market the Size of U.S. GDP

Anthropic is preparing to go public with a number that stands out even in the current AI boom. The company behind Claude is expected to tell investors that its total addressable market (TAM) exceeds $30 trillion, according to the Wall Street Journal, which cites people familiar with the preparations. The figure could still change before the filing.

Two more record ambitions come with it. Anthropic is targeting a valuation of about $2 trillion and wants to raise up to $100 billion in the offering. For comparison, SpaceX took in $86 billion in what was the largest IPO in history, and previous record holder Saudi Aramco raised $29 billion in 2019. Anthropic’s listing could come in September or October.

Seventh Most Valuable Company in the World, on Day One

A $2 trillion valuation would make Anthropic the seventh most valuable company in the world the moment it starts trading, just behind TSMC and ahead of SpaceX, which would slip to eighth. A company that had virtually no revenue three years ago would find itself in the same league as TSMC or SpaceX.

What stands out about this list is how tightly the AI value chain sits within it. Nvidia, TSMC and Broadcom supply the infrastructure, Microsoft, Alphabet and Amazon run the data centers, and Anthropic would enter on top as a model provider.

How It Compares With the SpaceX Prospectus

The $30 trillion figure is a deliberate attempt to top a specific benchmark. In its S-1, SpaceX claimed what it called the largest addressable market in human history ahead of its spring listing: $28.5 trillion. The breakdown Elon Musk’s company presented is the interesting part:

• Space-Enabled Solutions, the classic space business: $370 billion
• Connectivity, covering Starlink Broadband and Starlink Mobile: $1.6 trillion
• The entire remainder of $26.5 trillion sits in AI, with Enterprise Applications alone accounting for $22.7 trillion

Put differently, more than 90 percent of the market SpaceX promised its investors was already AI, while rockets and satellites amounted to a footnote in the math. Anthropic now lifts that AI share above $30 trillion, and it does so without any space business to pad the total. According to the people cited by the Wall Street Journal, the company arrived at the number by looking at the full scope of work that AI models could perform. At its core, the TAM covers what people currently do in offices.

What the Numbers Mean in Context

A total addressable market describes the theoretical maximum revenue a company could earn if every customer bought exclusively from it. The figure serves as a marketing instrument in the prospectus, and it gets read closely ahead of a listing.

$30 trillion is roughly the entire gross domestic product of the United States, about a quarter of global economic output, and roughly one and a half times what the whole European Union produces. The 191 technology companies in the S&P 1500 recently generated $2.4 trillion in combined revenue, less than a tenth of the market Anthropic defines as reachable for itself alone.

The company’s own books add further context. Anthropic’s annualized revenue recently passed $65 billion, putting it ahead of OpenAI. That puts the targeted TAM around 460 times above what Anthropic actually earns today. SpaceX, for its part, generated $18.7 billion in revenue in 2025 and posted a net loss of $4.94 billion, measured against a market the company itself valued at $28.5 trillion.

The Skepticism Was Already There for the Blueprint

The SpaceX figure drew debate in 2026. Finance professor Aswath Damodaran of New York University said at the time that the company was testing the limits of plausibility and going beyond them. Similar criticism greeted the valuation math behind the SpaceX IPO, whose share price has fallen sharply since the record debut. After peaking at roughly $2.4 trillion, the company now stands at about $1.8 trillion, below the level Anthropic is aiming for.

That trajectory is exactly what turns the Anthropic prospectus into a test case. The investors who bought a $28.5 trillion story in the spring will be offered the same story with a bigger denominator this autumn, this time without rockets as a hedge, and from a company whose product can shift technologically within six months.
