Summary · why it matters
A bipartisan coalition of 42 state attorneys general is building the liability framework for agentic AI that Congress has yet to codify, filling a federal regulatory void confirmed by the Congressional Research Service. In December 2025, the coalition, led by officials from Pennsylvania, New Jersey, West Virginia, and Massachusetts, issued a coordinated letter to 13 major AI companies including Anthropic, Apple, Google, Meta, Microsoft, OpenAI, and xAI, demanding chatbot safeguards with a response deadline of January 16, 2026. State AGs are repurposing existing UDAP statutes, consumer protection laws, civil rights frameworks, and antitrust authority to police AI behavior, an approach that produced a first-of-its-kind settlement by Texas Attorney General Ken Paxton with healthcare AI company Pieces Technologies over false accuracy claims. Connecticut's AI Responsibility Act, signed in May 2026, grants the state AG exclusive enforcement authority under CUTPA starting October 1, 2026, with a mandatory one-year cure period through September 2027, while New Jersey's Fair Price Protection Act, effective August 2027, allows a private right of action for surveillance pricing with treble damages and no cure period. The Pennsylvania AG has sought preliminary injunctions against an AI company for falsely representing a chatbot as a licensed psychiatrist, and the Florida AG launched a criminal investigation in April 2026 after a violent incident involving a chatbot. State AGs filed seven antitrust actions in 2026 alone, surpassing the prior two years combined, including a 30-state coalition continuing the monopolization case against Live Nation and twelve states suing to block the Paramount-WBD merger despite federal declination.
