Meta Cheyenne (Project Cosmo)

Meta's $800M-plus AI campus in Cheyenne, Wyoming, on Black Hills Energy grid power and a dedicated Enbridge solar-and-battery project; a wastewater contamination fight is open.

Buildings up, commissioning. Buildings are erected; cooling systems were being flushed in early 2026. Meta has not announced the campus open or an opening date (third-party listing: 2027). The city cut off wastewater discharge in March 2026; a $10,000 fine appeal is pending.
