On Tuesday, August 25, 2026, the Wall Street Journal reported that AI startup Anthropic is expected to inform investors that it sees its total addressable market (TAM) exceeding $30 trillion. This figure surpasses the $28.5 trillion TAM estimate previously reported by SpaceX in its May IPO filing, which described it as the "largest actionable TAM in human history," largely driven by AI technology.

TAM represents the annual revenue opportunity available if a product or service achieved 100 percent market share in its relevant market. To quantify its TAM, Anthropic is reportedly considering the full scope of work that could be completed with AI models.

Anthropic's large TAM projection supports its valuation, infrastructure investments, and product strategy, while framing its competition with companies like OpenAI and Google. The company is also preparing for a planned IPO, with its chatbot Claude projecting 2028 revenues between $190 billion and $200 billion, according to a Reuters report earlier this month.

Anthropic did not immediately respond to requests for comment.
