Anthropic has unveiled plans for what is expected to be the largest stock market debut in history, with a valuation potentially exceeding SpaceX's record $1.8 trillion, despite reporting losses of over $80 billion in the first half of 2026. The AI company, which will list on the Nasdaq under the symbol 'ANT', reported $16.3 billion in revenue during the same period. It plans to make investments "that may seem irresponsibly large at first glance," citing the need to invest aggressively in a rapidly changing technological landscape. Anthropic will be the first AI firm to go public, with OpenAI expected to follow early next year. The listing will require greater financial transparency, which could have significant implications for the US economy given AI's role in driving growth.
