The rush for OpenAI and Anthropic to go public is a strategic weapon, not just a financial necessity. The first AI leader to IPO can define market expectations for growth and valuation, putting immense pressure on the second company, which may have to compete against an already-established narrative.

Mamoon Hamid views AI's true market size not as a software category, but as a portion of the $60 trillion global labor market. Frontier models sell "units of labor," which is why companies like Anthropic can scale revenue so rapidly by tapping into a much larger pool of value.

Unlike established firms valued on current earnings, AI leaders like Anthropic command massive valuations because investors are betting on a non-zero probability that they could dominate the entire market and become the world's most valuable company, justifying extreme multiples.

The urgency behind the Anthropic IPO, coupled with an astronomical valuation and slowing growth, is a classic sign of a market top. This behavior suggests insiders want to sell to the public at peak hype before competition and commoditization erode their moats.

Anthropic's growth to a $30 billion annualized run rate in just over a year is unprecedented. It added $11 billion in run rate in March 2025 alone—the equivalent of Databricks and Palantir combined. This signals that enterprise demand for intelligence has a near-infinite Total Addressable Market (TAM).

The true market opportunity for AI is not merely replacing existing software but automating human labor. This reframes the total addressable market (TAM) from the ~$400 billion global software industry to the $13 trillion US-only labor market, representing a thirty-fold increase in potential value.

Anthropic's massive new valuation isn't just a reflection of its success. It's a strategic financial maneuver by late-stage investors to 'anchor' a high price in the market's perception, aiming to maximize value when the company eventually goes public.

Airtable CEO Howie Lu dismisses the $1 trillion TAM estimate for AI agents. He argues the true market is the entire GDP of white-collar labor, amounting to tens of trillions of dollars. This reframes the opportunity from a large new market to a complete replacement of an existing economic structure.

Anthropic's and OpenAI's massive revenue forecasts ($300B+ combined) aren't about displacing existing software spend. The core bet is that AI will capture a large portion of the trillion-dollar consulting and services budget, dramatically expanding the total addressable market for technology.
