On June 1, ET, Anthropic officially filed for a confidential IPO with the U.S. Securities and Exchange Commission (SEC), potentially becoming the first AI startup with a trillion-dollar valuation. Co-founded in 2021 by former OpenAI Vice President of Research Dario Amodei, his sister Daniela Amodei, and several former OpenAI core members, the San Francisco-based company focuses on developing safe AI systems, with its flagship Claude series competing with ChatGPT. According to multiple media reports, Anthropic could officially list on the Nasdaq or NYSE as early as October 2026. The company’s valuation grew from approximately $61.5 billion in March 2025 to about $965 billion just over a year later, surpassing OpenAI’s valuation of approximately $852 billion in its March funding round. Anthropic's annualized revenue surged from $9 billion at the end of 2025 to over $44 billion by May, with approximately 80% coming from enterprise customers. The company posted a loss of roughly $5.6 billion in 2024, but aims to reach $70 billion in revenue and $17 billion in free cash flow by 2028.
