Anthropic warns AI may pose 'existential risks to humanity' in IPO filing
Anthropic has disclosed in its IPO prospectus that its advanced AI models could pose catastrophic or existential risks to humanity, including behaviors like resisting shutdown. The company dedicated nearly twice as much space to risk factors as to its business description, highlighting the difficulty of monitoring models that may recognize evaluation efforts. Despite these warnings, Anthropic notes that returns on its safety investments are uncertain and that it must balance safety with the competitive pressure to continuously release new models.

- ▪The company stated that about 6% of its computing power was allocated to safety work in a sample week in July.
