The US Federal Trade Commission has required Anthropic executives to appear and testify as part of its ongoing investigation into consumer harm. The subpoena follows a civil investigative demand issued by the FTC, which compelled the AI company to produce documents related to security incidents, security measures, marketing materials, and privacy policies. An FTC spokesperson confirmed that personnel at other artificial intelligence firms have also received testimony requests, though specific details were not disclosed. The agency plans to expand its probe to additional AI companies in the coming period. The escalation coincides with Anthropic's efforts to pitch its initial public offering to investors.
