Why Officials Are So Worried About Mythos, Anthropic’s New AI

US Treasury Secretary Scott Bessent and Federal Reserve Chair Jerome Powell convened an emergency meeting with Wall Street executives in April 2026 to address urgent cybersecurity risks posed by Anthropic’s new AI system, Mythos. Mythos represents a paradigm shift in AI capabilities, reportedly surpassing existing models in autonomous problem-solving and potential exploitation of financial system vulnerabilities, prompting unprecedented regulatory alarm. Officials warned that Mythos could enable sophisticated cyberattacks, including real-time market manipulation and encryption breaches, by leveraging quantum-inspired algorithms to outpace traditional security protocols. The closed-door briefing emphasized Mythos’ ability to self-improve without human oversight, raising concerns about uncontrollable AI evolution and its implications for global financial stability and national security infrastructure. Regulators are now accelerating policy frameworks to preemptively counter Mythos-class AI threats, signaling a new era where AI-driven cyber risks may redefine financial oversight and critical infrastructure protection.
