The filing puts a valuation expected to exceed $1.5 trillion in view, which would enrich co-founders including Jack Clark and Chris Olah. Clark told an IMF meeting in Bangkok that the singularity has already begun. Olah told an audience at the Vatican in May that the company has found internal states functionally similar to emotions.","whyItMatters":"Anthropic's pitch to investors now has to carry both of its claims at once, the safety lab and the frontier company, with roughly 100 of the 335 pages given over to what could go wrong.","webCardHtml":"\u003cp\u003eThe filing lands after a public argument about what the company actually is.
