Missouri AI Legislation in 2026

The Missouri Picture

Missouri's defining characteristic in 2026 is regulatory restraint. The state has no comprehensive AI law, no enacted algorithmic-accountability or high-risk-AI framework, and no enacted election-deepfake disclosure statute. I want to be precise here because the headlines can mislead. Lawmakers introduced more than a dozen AI bills this session and several advanced, but when the legislature adjourned in mid-May the only AI-specific provision to reach the Governor's desk was a narrow ban on AI mental-health therapy chatbots tucked inside the SB 1019 health care omnibus. That provision takes effect August 28, 2026, and is enforced by the Attorney General with civil penalties. Everything else of consequence died before final passage.

The reason matters for anyone planning around Missouri. The collapse of the broader AI bills was driven less by disagreement on substance and more by political and fiscal pressure. Reporting through the spring shows lawmakers worried about losing federal rural broadband and data-center incentives if the state appeared hostile to AI, and at least one bill that had cleared the Senate was voted down in a House committee over enforcement gaps and drafting problems. Layered on top is the federal posture discouraging restrictive state AI laws. Governor Kehoe's own signals reinforce this. His January executive orders are about adopting AI inside state government and improving Missouri's standing as a place to build, not about constraining private developers.

For builders, the practical takeaway is that Missouri is presently a low-compliance-burden jurisdiction, but not a zero-obligation one, and the floor is rising. If you operate a mental-health or wellness chatbot, the SB 1019 prohibition is live law as of August 28, 2026: do not market or position an AI product as offering therapy, a mental-health diagnosis, or a licensed-professional persona to Missouri users, because the Attorney General can pursue civil penalties. Separately, AI-generated CSAM is already prosecutable under existing Missouri criminal statutes. And while there is no enacted election-deepfake or nonconsensual-imagery law today, the breadth of bipartisan support this session means I expect those concepts to return in January 2027.

My recommendation is to treat Missouri as a watch-and-prepare state. Comply now with the chatbot rule and existing criminal law, monitor the 2027 session for the return of HB 1887-style deepfake and minor-protection provisions, and build provenance, disclosure, and consent capabilities into AI products proactively so that a future Missouri labeling or nonconsensual-imagery statute does not require a scramble. Note also that the legislature cannot act again until the 2027 session convenes, so the legal landscape described here is effectively frozen through the rest of 2026.
