Anthropic, the company behind the Claude chatbot, estimates that its total addressable market (TAM) could exceed $30 trillion, according to a report by The Wall Street Journal.

The company calculates the scale of its opportunity by looking at the amount of work that could potentially be performed using AI models. That figure, if it holds, would rank the opportunity among the largest ever framed by a technology company ahead of a public listing. TAM figures of this kind, which measure the full universe of spending a company could theoretically capture, are a standard part of pre-IPO positioning, though actual revenue capture is typically a small fraction of such estimates.

The estimate could play a key role in shaping investor expectations around Anthropic's future growth, valuation, and infrastructure investments as it prepares for a potential initial public offering (IPO). The disclosure comes amid heavy capital spending across the AI sector on data centers and computing capacity, a trend that has made investor framing of long-term market opportunity especially consequential for companies weighing public listings.

Anthropic is best known as the developer of Claude, an AI chatbot that competes with other large language models in the rapidly expanding market for generative artificial intelligence. The San Francisco-based company, founded in 2021 by former OpenAI researchers, has drawn major investments from firms including Google and Amazon. Its potential IPO would add a second major U.S. frontier-lab listing to the market following OpenAI's own reported listing preparations, and how investors respond to its TAM framing may signal how much appetite remains for capital-intensive AI growth stories.
