Trader sentiment strongly favors an Anthropic IPO closing market cap above $1.8 trillion, driven by the company's confidential filing and reported targets for a $2 trillion-plus Nasdaq listing as early as mid-November 2026. Revenue has surged to a $65 billion annualized run rate by July, with projections exceeding $110 billion by year-end, supported by Claude large language model releases such as Opus 5.5 that deliver improved speed, lower costs, and stronger safety benchmarks. Massive infrastructure commitments exceeding $500 billion underscore competitive positioning against OpenAI and others, though high operating losses and Big Tech dependencies introduce execution risks. Upcoming catalysts include the formal roadshow and any pre-election market conditions that could finalize the debut valuation.
