Anthropic has formally alerted investors in its initial public offering prospectus that its technology may pose "existential risks to humanity." The nearly $1 trillion AI start-up, led by Dario Amodei, circulated the S-1 filing with a small group of partners in recent days.

The company devoted almost a third of the lengthy document to detailing "risk factors." These include the potential for increasingly advanced AI models to manipulate, blackmail, and exhibit other unpredictable behaviors. Beyond these high-stakes concerns, Anthropic outlined more prosaic operational risks, specifically the extreme concentration of its customer base. According to people familiar with the filing, close to a quarter of the company's revenue last year came from just two clients.
