Anthropic warns of 'catastrophic risk' to humankind ahead of blockbuster share listing
The company will be the first true artificial intelligence company to go public as tech firms continue to invest heavily in AI.

Anthropic has warned artificial intelligence could pose "catastrophic or existential risks to humanity" as it unveiled details of its planned blockbuster stock market listing in the US.
The company behind AI chatbot Claude revealed losses of more than $80.7bn (£60.5bn) in the first half of the year, but said it had $112.4bn in cash or equivalents, and generated revenues of $16.3bn over the same period.
The number of shares to be released, their price range, and a date for the listing have not been disclosed.
Its most significant rival, OpenAI, quickly followed suit, saying it, too, intended to go public. That listing is now expected to occur early next year, according to a person familiar with OpenAI's plans.
