Cheyenne residents are actively pursuing a ballot referendum to reverse the City Council's recent decision to annex 3,460 acres of land for a proposed Microsoft data center campus. The annexation, which would allow the tech giant to connect to city utilities and services, was approved by a 6-3 vote despite significant public objection during council meetings.

Local opposition, including a "National Day of Protest against Data Centers," highlights concerns that the City Council is prioritizing data center development over the community's best interests. Residents point to a recent contamination of the city's sanitary sewer system by a Meta data center as evidence of potential risks, questioning the safety assurances from developers.

To trigger the referendum and potentially overturn the annexation, 3,000 legally registered Cheyenne voters must sign a petition by August 2, 2026. Signature collection locations include the Laramie County Public Library.
