Anthropic Plans November IPO Targeting Valuation of Up to $2 Trillion

Anthropic, the AI company behind the Claude software, is moving quickly toward a public market debut that could rewrite the record books. Bloomberg reports that the company plans to begin marketing its initial public offering as soon as the week of 9 November, with the stock potentially beginning to trade as early as 16 November. A separate report noted that Anthropic is scheduled to meet with prospective investors on 14 October. The company is targeting a valuation of up to $2 trillion, a figure that would make it the largest IPO of all time. Reuters separately reported obtaining a copy of Anthropic's S-1 prospectus, which showed the company's revenue grew 12 times in 2025, finishing the year at roughly $4.6 billion. Anthropic was founded in 2021 by former OpenAI employees, including CEO Dario Amodei, and has built a reputation as one of the world's leading AI labs through its Claude models and a strong focus on the enterprise market.
