Anthropic is preparing to tell investors its total addressable market exceeds $30 trillion — a number so large it makes SpaceX’s $28.5 trillion claim from May look almost modest by comparison. The Wall Street Journal reports the AI company will anchor its IPO pitch on that figure, calculated by tallying all the work AI models could theoretically absorb.
Context helps here. The 191 technology companies in the S&P 1500 collectively generated $2.4 trillion in revenue last year, according to FactSet. That means Anthropic’s theoretical ceiling is more than twelve times what the entire publicly traded U.S. tech sector actually earned. TAM figures are always aspirational — they assume 100 percent market capture — but this gap is the kind of thing that makes institutional investors squint.
The company does have real momentum to point to. Anthropic doubled its revenue in the second quarter to $11.6 billion and projects roughly $190 billion to $200 billion by 2028. It’s reportedly chasing a $2 trillion valuation and wants to raise up to $100 billion, with a public debut possibly landing in September or October.
Whether the pitch lands depends on whether investors buy the underlying assumption: that AI models will eventually take over a meaningful slice of global knowledge work, not just assist at the margins. That’s the same bet OpenAI, Google, and Microsoft are making, but Anthropic is putting the largest number on it yet. If the IPO prices anywhere near that valuation, the company will need years of triple-digit growth just to justify the multiple — and the TAM slide will be doing a lot of rhetorical heavy lifting.
