**Rapid revenue expansion and investor enthusiasm for a record-setting IPO are anchoring trader expectations for Anthropic’s closing market cap above $1.8 trillion.** The company reached a $965 billion post-money valuation in its May 2026 Series H round after reporting a $47 billion annualized revenue run rate, more than five times the level at the end of 2025. Recent reporting indicates backers anticipate an October 2026 listing at roughly $2 trillion or higher, supported by forecasts of $100–120 billion annualized revenue by year-end and longer-term projections approaching $190–200 billion by 2028. Confidential SEC filing in June, multiple frontier Claude model releases, and gains in agentic coding capabilities have reinforced competitive positioning against OpenAI, while strong institutional demand in the latest round signals sustained capital-market appetite for frontier AI assets. These factors explain the market-implied 64.5% probability on the top bracket, tempered by the typical volatility of late-stage IPO pricing and execution risk.
