Anthropic, the AI company behind the Claude chatbot, is planning to raise up to $64bn (£48bn) when it lists its shares for sale on New York's Nasdaq stock exchange. The loss-making company said it will offer its shares for between $70 and $78 each in its initial public offering (IPO), which is expected to go ahead this month. This would value Anthropic at between $1.1 trillion and $1.3 trillion which, although large, is below the $2 trillion some analysts had predicted weeks ago.
