The Quietest Therapy-Bot Ban in America: Missouri Codifies the Consumer-Fraud Theory
Missouri made advertising a chatbot as a therapist an unlawful trade practice, fined per offense, enforced by the attorney general.
On May 15, the Missouri legislature truly agreed to and finally passed SB 1019, an omnibus health care bill carrying a clause that quietly does something Colorado and Vermont did loudly: it bans AI therapy chatbots. The mechanism is what makes it interesting. Missouri did not route this through its licensing boards or its health code. The bill explicitly states that a violation of its prohibitions concerning AI in mental health services constitutes an unlawful practice under the Missouri Merchandising Practices Act — the state's consumer-fraud statute. The violation is the claim, not the harm.
The operative language, carried from the companion bill SB 1444, is narrow and unusually clean. No person or entity that develops or deploys AI shall advertise or represent to the public that the AI is or is able to act as a mental health professional, or is capable of providing therapy services, psychotherapy services, or a mental health diagnosis. The attorney general enforces the act, any individual may report violations, and if the attorney general finds that a violation occurred, the attorney general shall commence a civil action. Fines run $10,000 for the first offense and $20,000 for each one after.
This is the same theory Texas Attorney General Ken Paxton deployed against Character.AI and Meta AI Studio at the end of May — a theory we unpacked when Texas opened its inquiry. The argument: marketing a chatbot as a therapist is a deceptive trade practice, full stop. You do not have to prove a teenager was harmed. You do not have to litigate whether the chatbot's clinical reasoning was negligent. You only have to show the product was sold as something it cannot be. Missouri has now codified that theory into statute, with a fixed price tag attached.
Two things matter about the choice of vehicle. First, consumer-fraud statutes do not require the plaintiff to be a patient — they protect the public from being misled, which means Attorney General Andrew Bailey can act before anyone dies. Second, the harm-free trigger sidesteps the Section 230 fights and the duty-of-care arguments that have bogged down wrongful-death cases like Garcia and Raine. Missouri is not asking whether the chatbot caused the suicide. Missouri is asking whether the homepage said the word "therapy."
The drafting is also conspicuously narrow. The law doesn't offer a broad definition of AI itself, but focuses on these specific prohibited actions, aiming to prevent consumer deception and ensure mental health services remain under the purview of licensed human professionals. A chatbot that talks to a user about anxiety while never claiming to be a therapist appears untouched. The statute regulates the marketing surface, not the conversational one. Whether that distinction holds when a product page says "AI companion" and the bot itself says "as your therapist, I think…" is a question Bailey's office will eventually answer in a complaint.
What's most telling is the silence around it. Missouri completed legislative action on SB 1019, an omnibus health care bill that includes a prohibition on offering AI therapy chatbots; the bill is slated to take effect Aug. 28, 2026. A deep-red state added itself to the regulatory map with almost no press coverage, because the language sits inside a health-care omnibus next to provisions on Lyme disease surveillance and municipal hospital investments. The pattern is now legible: red states are regulating AI therapy through fraud law, blue states through health law, and the companies face both.
For anyone watching this space, the operational question shifts. It is no longer whether AI therapy will be regulated. It is which of the two doctrinal frames — consumer fraud or scope of practice — gets to the first injunction first. Metonym tracks both, because the evaluation question underneath them is the same: what does it take to show, in court, that a chatbot was sold as something it is not equipped to be?
