Compass Hoffman Estates (former Sears headquarters)

Compass Datacenters' first Illinois campus: five hyperscale buildings on 197 acres of the former Sears headquarters in Hoffman Estates, approved in 2025 and under construction.

Under construction. Village approvals came in Feb. 2025; the mayor said in Apr. 2026 demolition finished and construction began. About 200 MW of IT capacity is a tracker's estimate; Compass and ComEd have published no MW figure, and no tenant is named.
