Anthropic is expected to tell investors in its IPO filing that its potential revenue opportunity exceeds $30 trillion, surpassing SpaceX's earlier estimate of $28.5 trillion. The company is using total addressable market, or TAM, to highlight the scale of work AI models could complete in the future. SpaceX previously described its TAM as "the largest actionable market in human history," with $26.5 trillion tied to AI opportunities. Anthropic's second-quarter revenue has topped $11.6 billion, and its IPO could raise as much as $100 billion at a target valuation of about $2 trillion. The plans remain under discussion, with an IPO possible as early as September or October.
