According to Mordor Intelligence, the chicago data center market size is expected to grow from 1.9 GW in 2025 to 2.03 GW in 2026 and is forecast to reach 2.81 GW by 2031 at 6.73% CAGR over 2026-2031.

This report is Segmented by Data Center Size (Small, Medium, Large, Massive, Mega), Tier Type (Tier 1&2, Tier 3, Tier 4), Data Center Type(Colocation, Cloud Service Providers (CSPs), Enterprise, Modular, and Edge). The Market Forecasts are Provided in Terms of Value (USD).
Hyperscale operators are accelerating footprint expansion as premier coastal markets hit power ceilings. Amazon's USD 20 billion program for nuclear-backed campuses in the Mid-Atlantic signals a readiness to diversify locations, enabling Chicago to draw similar mega-projects. Microsoft and BlackRock's USD 30 billion AI-infrastructure alliance has earmarked Midwest parcels, while Equinix's USD 15 billion xScale venture identifies Chicago as an early launch point. Financial-market latency needs further amplify demand; CME Group's private Google Cloud region in Aurora exemplifies this enterprise pull.
A USD 232 billion global edge-market in 2024 is reshaping site requirements for Chicago's manufacturers, retailers and financial firms. CoreSite's CH2 earned NVIDIA DGX-Ready status, reinforcing the metro's suitability for AI inference clusters. Telecommunications carriers such as Comcast anchor Northlake facilities to support 5G, content-delivery networks and low-latency over-the-top workloads.
Projected monthly customer bills could climb USD 10.50 as data-center demand raises grid-balancing charges. PJM auction-clearing prices have risen, forcing operators to hedge higher capacity costs. Lawmakers are studying safeguards to prevent hyperscale strain on legacy infrastructure and to protect ratepayers.

Massive footprints delivered 44.12% share of Chicago data center market in 2025, reflecting a matured ecosystem supporting financial-services and legacy workloads. However, Mega campuses are set to outpace every other category at a 7.72% CAGR through 2031 as AI training clusters hunt for blocks of contiguous power above 100 MW. T5's 480 MW suburban campus and Compass' five-building redevelopment of the former Sears HQ evidence this pivot, each engineered for >= 50 kW per rack densities.
Small and medium halls remain viable for edge and enterprise hybrids but face gradual absorption into larger wholesale footprints. Hyperscale tenants favor the operating leverage and custom mechanical-electrical topologies available in Mega builds, pressuring owners of smaller suites to differentiate via latency-critical or specialty compliance offerings.
