AI giant Anthropic has filed for an IPO, disclosing a net loss of $80.7 billion and revenue of approximately $16.3 billion for the first half of the year, with Q2 revenue up 1368% year-over-year. The company is expected to list on Nasdaq next month under the ticker "ANT," with a valuation of approximately $1.5 trillion, down from $2 trillion a week ago. The filing also warns of catastrophic and existential risks to humanity posed by AI, and notes that the company's growth rate may decline while costs will continue to increase.
