Anthropic, the company behind the Claude chatbot, is preparing to tell investors it is chasing a market worth more than $30 trillion as it moves closer to a public listing, according to reports aggregated by MSN from Bing News.

That number is not a revenue forecast, despite one headline framing it that way. It is a total addressable market, or TAM — Silicon Valley shorthand for the entire pool of spending a company believes it could theoretically compete for. Anthropic is expected to discuss the figure with investors as part of its potential IPO process, according to MSN.

The comparison being drawn is to SpaceX, whose own TAM estimate has been reported at $28.5 trillion. If Anthropic's number holds, it would top Elon Musk's rocket company. One MSN report notes the $30 trillion figure sits just shy of the entire gross domestic product of the United States.

Yahoo Finance UK, meanwhile, has published a "five things to know" explainer on Anthropic ahead of what it describes as the company's Wall Street debut, a sign that mainstream financial media is already treating the listing as a near-term event.

A word of caution for readers: TAM figures are marketing, not accounting. They are self-reported, unaudited, and designed to make a growth story feel limitless. Nothing in these reports says Anthropic expects to earn $30 trillion.

Why it matters: an AI company claiming a slice of nearly the whole US economy sets the terms for how public-market investors will price the entire sector — and how far expectations can stretch before they snap.
