Anthropic IPO filing points to a $40 trillion market: worker pay

Anthropic's IPO prospectus contains a number that appears nowhere in its pages, yet falls out of the arithmetic: a potential market of more than $40 trillion a year. The figure starts from the economic value of all knowledge work in 2025, meaning lawyers, analysts, programmers, consultants, translators and journalists. Roughly speaking, $40 trillion is the sum of their salaries.

The S-1 is the document US companies file to go public. It is long and dry by design, and Anthropic's devotes almost 100 pages to everything that could go wrong for the business and for the investors who buy in. The market estimate is not written out as such. It emerges from reconstructing the filing's logic, the way an industry's unspoken assumptions surface once someone does the sums.

Why the economics support the pitch

The company's numbers fit that narrative. Anthropic reports a gross margin of 85% in the first half of this year. Its computing cost has fallen from $2.50 for every dollar of revenue to under 50 cents in a little over a year. In other words, the product is already profitable, and what remains is capturing the market.

That is a break from the traditional software story. A spreadsheet licence was worth what it was because it made an accountant more productive, and the accountant kept earning a salary. Microsoft's market was a fraction of what its users generated. Here, the addressable market is the user's entire pay.

A caveat on potential markets

None of this means it will happen. Potential-market figures are often fantasies dressed up in spreadsheet solemnity: they justify valuations but do not predict outcomes. Still, they reveal how a company looks at the world. A tools company sees customers with problems, while this filing treats the labor market as a spending line.

For comparison, the 40 trillion exceeds the $28.5 trillion attributed to SpaceX, which was framed around space. The open question for workers and shareholders alike is how much of that money keeps flowing to monthly paychecks and how much ends up with Anthropic's investors. The company has also designed an unusual power structure to keep shareholders from controlling it after the listing.
