Anthropic warns its AI could be dangerous. So why do people want to invest?

Anthropic warned that its AI could "pose catastrophic or existential risks to humanity" without appropriate safeguards, oversight and security measures, a warning included in its pitch to future shareholders. The company is set to become the first fully AI-focused company to list on the US stock market, with an expected record-breaking valuation, and its IPO filing reveals details of its finances and ethics. A BBC podcast episode features AI correspondent Marc Cieslak explaining the filing and why Anthropic's leadership wants investors to believe AI might destroy the world.
