Anthropic has officially filed for a confidential IPO with the U.S. Securities and Exchange Commission (SEC) on June 1, 2026, according to TradingKey. The filing marks a significant milestone for the AI company, which could become the first AI startup to achieve a trillion-dollar valuation. TradingKey reports that Anthropic may list on the Nasdaq or NYSE as early as October 2026, having raised over $129 billion cumulatively, with a latest Series H-1 round in May 2026 bringing in approximately $65 billion. The company's valuation has surged from about $61.5 billion in March 2025 to roughly $965 billion, surpassing OpenAI's estimated $852 billion valuation.

Anthropic's financial trajectory has been explosive. The article reports annualized revenue grew from $9 billion at the end of 2025 to over $44 billion by May 2026, a fivefold increase. Approximately 80% of revenue comes from enterprise customers, including eight of the Fortune 10. The number of clients paying over $1 million annually more than doubled from 500 in February to over 1,000 by April 2026. In April, Anthropic's enterprise AI market share reached 34.4%, surpassing OpenAI's 32.3% for the first time. The company aims for profitability by 2028, targeting $70 billion in revenue and $17 billion in free cash flow, contrasting with OpenAI's expected profitability not before 2030.

The IPO presents significant implications for the AI market. Anthropic's listing could set a precedent for AI-native companies, potentially reshaping valuation expectations and public-market dynamics. The company plans to allocate a substantial portion of its funding to expand computing infrastructure, purchasing Nvidia's next-generation GPUs and Google TPUs, and deploying data centers across the U.S., Europe, and Asia. However, the article also flags risks: computing power bottlenecks, scrutiny of its supply chain by the U.S. Department of Defense, and potential AI sector bubble due to its high valuation. Investors will need to weigh these factors when considering participation in the IPO.
