Montana AI laws: what's in force, and what's coming

Montana passed a cluster of AI laws in its 2025 session: limits and human-review duties for state and local government AI use, a Right to Compute Act that restricts government limits on computing and requires risk policies for AI-controlled critical infrastructure, and laws on election and sexual deepfakes. The Legislature does not meet in 2026, so no new AI statutes were added this year; the next session starts January 2027.

A record supports your compliance evidence process. It is not a legal finding or a certification. Systems that call Planisphere's gate API can also hold or refuse an action before it runs.
