Montana datacenter infrastructure
Montana hosts 8 documented datacenter projects representing $1.8B in disclosed investment and 1.8 GW of power capacity. The state has emerged as a hub for AI/ML infrastructure, attracting hyperscaler investment. Multiple hyperscale operators have established presence in the state.
Snapshot note. The counts, investment and capacity figures on this page come from the wiki’s project dataset as it stood in December 2025, and have not been refreshed since. US datacenter announcements grew substantially through 2026, so treat these as a floor rather than a current tally. See data sources for methodology.
