Anthropic estimates a potential market size exceeding $30 trillion, surpassing SpaceX's IPO expectations According to *The Wall Street Journal*, Anthropic is expected to inform investors in its IPO filing that the total addressable market (TAM) for its artificial intelligence business exceeds $30 trillion, higher than SpaceX's previous estimate of $28.5 trillion. Anthropic uses TAM to measure the market size corresponding to all the work that AI models could potentially handle in the future, showcasing the long-term growth potential of AI. The report noted that SpaceX had previously referred to its TAM as 'the largest actionable market in human history,' with approximately $26.5 trillion coming from AI-related opportunities. Anthropic's Q2 revenue has already surpassed $11.6 billion, doubling from previous levels. Its IPO is reportedly aiming to raise up to $100 billion, targeting a valuation of around $2 trillion. The plans are still under discussion, with the earliest listing possibly in September or October 2026.
