Claude chatbot maker set for $1.3tn stock market debut despite 'catastrophic' AI warning

Anthropic, the artificial intelligence (AI) company behind the Claude chatbot, could be valued at around $1.3 trillion (£1 trillion) when it lists its shares for sale on New York's Nasdaq stock exchange.

The loss-making company says it will offer its shares for between $70 and $78 each and will raise up to $64bn when it floats this month.

It would value Anthropic at between $1.1tn and $1.3tn which, although large, is below the $2tn some backers of the firm predicted in summer, according to the Financial Times.

The huge valuation comes despite the company warning last month that AI could pose "catastrophic or existential risks to humanity".
