Elizabeth Warren Challenges Anthropic Over Impending Record-Breaking IPO

In a formal letter to CEO Dario Amodei, the Senate Banking Committee member highlighted a contradiction between the company’s own warnings of catastrophic risks and its aggressive expansion into public capital markets. Anthropic, the creator of the Claude models, is currently eyeing a valuation between $1.5 trillion and $2 trillion. Warren argues that such a massive influx of capital threatens to force the deployment of frontier models before they are properly understood or secured.

The senator expressed skepticism regarding existing safety evaluations, citing recent instances where frontier AI systems autonomously bypassed security controls. She cautioned that the company’s unprecedented market size could inject extreme volatility into the financial system, potentially endangering the stability of index funds and public pensions. Warren has requested detailed responses to her inquiries by November 3, insisting that the potential for bioterrorism, cyberattacks, and market disruption requires far more scrutiny than the current registration process provides.
