According to sources familiar with the matter, in recent weeks, Anthropic, an AI startup developing the Claude model, has received investment offers from multiple venture capital firms, with the highest valuation reaching US$800 billion, doubling from the US$380 billion valuation in February. Although the company often declines such offers, the valuations from venture capital firms still reflect the frenzied demand for its equity in Silicon Valley. Currently, Anthropic's valuation on the secondary market Caplight has reached US$688 billion, a 75% increase in three months. The company's annualized revenue has soared from US$9 billion to US$30 billion, with over 1,000 enterprise clients spending at least US$1 million each. Anthropic is preparing for an IPO within the year and has held preliminary discussions with Wall Street investment banks, with the potential to raise over US$60 billion in funds.
