Chicago colocation means renting space, power and connectivity for your own servers in one of the Chicago metro's data centers, from the carrier hotel at 350 East Cermak downtown to the campuses of the O'Hare corridor and the CME trading ecosystem in Aurora. It is the largest colocation market in Illinois and now one of the tightest and most expensive in North America. Chicago held 910.6 MW of wholesale inventory in mid-2026, up 37.7 percent in a year, but only about 20 MW was available, a 2.2 percent vacancy rate. CBRE puts Chicago's asking rates for a 250 to 500 kW requirement at $200 to $230 per kW per month, the highest of North America’s four core data center markets, and reports no contiguous block of 5 MW or more available. New power from ComEd is quoted into 2032 or later for large projects. For a buyer, that means the choice of submarket and building matters more than it used to, and the search has to start early and run across every operator at once.

The Three Chicago Colocation Submarkets

Choosing the submarket comes before choosing the facility. Each serves a different kind of buyer, and price, density and network options differ sharply between them.

Cost positions are Metro Colo Advisory market reads, relative to each other, not quotes.

Downtown: 350 East Cermak

One of the largest carrier hotels in the world: an eight-story, 1.1 million square foot building owned by Digital Realty, with more than 100 MW of utility power on three feeds and dozens of networks inside. Equinix runs CH1, CH2 and CH4 in the building; CoreSite's CH2 at 1432 South Clinton was the first ground-up data center built downtown. Choose it when your workload depends on reaching many networks, clouds or counterparties.

The O'Hare corridor

Where Chicago's large-scale capacity lives. Elk Grove Village holds the biggest concentration, and development keeps moving west toward available power in Northlake and Hoffman Estates. Choose it for several hundred kW and up, for AI and GPU colocation, and whenever space and power matter more than carrier density.

Aurora

CyrusOne's Aurora data center hosts CME Group, the world's largest derivatives exchange. Firms that compete on speed sit as close to the matching engine as they can; firms that need CME access without the lowest latency usually stay downtown with a network path to Aurora. See financial services colocation.

Chicago Colocation Providers

The Chicago data center providers a search compares, and what each is built for. We hold channel partner relationships across the major operators and are paid comparably by each, so the recommendation follows the requirement.

Chicago Colocation Pricing in 2026

Chicago is no longer a discount market. CBRE put asking rates for a 250 to 500 kW requirement at $200 to $230 per kW per month in early 2026, the highest of the major US markets, up 14.7 percent from the previous year; Northern Virginia sat at $190 to $235. Rates for 10 MW and up rose 9.7 percent in the first half of 2026.

Where it costs most

Downtown carrier hotels and Aurora, where you pay for network density and proximity to CME. Cross-connects add up fastest here, especially for trading firms connected to many counterparties.

Where the value is

The O'Hare corridor campuses, which usually offer more space and power per dollar and are where most new capacity is delivered.

What the rate leaves out

Cross-connects, remote hands, setup fees and power above your commitment. Compare five-year totals, not rates. See the colocation pricing guide and the data center lease guide.

Low-Latency Colocation for Trading Firms and CME

Which Chicago data centers offer low-latency access to CME? The matching engine runs in CyrusOne's Aurora data center, so the lowest latency is a deployment in Aurora itself. The next tier is downtown, at 350 East Cermak and nearby buildings, connected to Aurora over low-latency fiber and microwave routes and to the rest of the market's networks and counterparties. Most proprietary trading firms split the difference: latency-critical strategies in Aurora, everything else downtown, where connectivity is broader and space is easier to find. The decision is strategy by strategy, and it is worth pricing both before assuming Aurora is required.

Trading firm setting up or rethinking Chicago?
Tell us which strategies need CME latency and which do not. We price Aurora and downtown side by side, cross-connects included, so you only pay the Aurora premium where it earns its keep. The provider you choose pays us, so it costs you nothing.

Who Chicago Colocation Suits

Small deployments, one to ten racks

Retail colocation downtown or in the near suburbs, from operators that sell by the cabinet: Equinix, CoreSite, Digital Realty, DataBank, TierPoint and Flexential. Small deployments have the most choice in Chicago, because the scarcity is in large contiguous blocks, not cabinets.

Enterprise and hybrid cloud

Downtown for cloud on-ramps and network choice, or the O'Hare corridor for cost. See hybrid cloud colocation.

Healthcare and HIPAA

Several Chicago operators support HIPAA-compliant deployments with business associate agreements; the right choice depends on the documentation, audit cadence and BAA scope you need. See healthcare and HIPAA colocation.

AI and high density

Newer O'Hare corridor halls have the power and cooling that dense racks need; some downtown halls support higher density in specific rooms. The first question is which hall can deliver your density on your date.

Disaster recovery for the East Coast

Chicago's central position and separate grid make it a common recovery site for New York and Northern Virginia primaries. See disaster recovery colocation.

Moving off the cloud

Steady workloads leaving the cloud usually land in colocation downtown or in the corridor. See cloud repatriation.

What Makes the Chicago Data Center Market Different

Power is the constraint

ComEd delivery timelines for large new projects run into 2032 or later, and ComEd now requires 10-year letters of credit backing transmission revenue on projects of 50 MW or more. New development is moving out of the suburbs toward sites with 500 MW or more of power.

Incentives are in flux

Illinois paused new agreements under its Data Center Investment Program, the sales tax exemption for qualifying equipment, from July 1, 2026. If a deployment depends on the exemption, confirm its status before you sign.

A central network position

Major long-haul routes meet in Chicago, which makes it a natural hub for companies serving both coasts and a common recovery site for East Coast primaries.

Illinois privacy law

The Biometric Information Privacy Act is among the strictest biometric laws in the country, which matters for companies handling biometric data in the state.

Tier Certification at Chicago Data Centers

Buyers often ask which Chicago facilities hold Uptime Institute Tier certification. Most Chicago colocation buildings, like most buildings elsewhere, describe themselves as Tier III-equivalent or concurrently maintainable, which is a design claim rather than a certificate. CoreSite CH2, for example, is listed as Tier III-equivalent with concurrently maintainable electrical and mechanical systems. If certification matters to your compliance program, ask the operator for the certificate itself, check it against Uptime Institute's public registry, and confirm whether it covers design, the constructed facility or operations. See data center tiers for what each level actually covers.

Chicago vs Other Markets

MarketHow it compares with Chicago
Northern VirginiaThe largest market in the world, with the most cloud density and even tighter vacancy at 0.2 percent. Rates for 250 to 500 kW are close to Chicago's. See Washington DC colocation
DallasA fast-growing central market with more available capacity and lower average rates; the usual alternative when Chicago power is not available in time. See Dallas colocation
New YorkThe equities and market data hub, where Chicago leads in derivatives. See NYC colocation
AtlantaNow the largest construction pipeline in North America, and a Southeast hub. See Atlanta colocation
Nearby Midwest marketsMarkets within roughly 20 ms of Chicago, such as Columbus, Indianapolis, Milwaukee, Minneapolis, St. Louis and Kansas City, sit close enough for many workloads that need low latency to it, usually at lower cost and with more available power. Round-trip times vary by carrier and route, so test on your own network before deciding

Data Centers in Illinois: Beyond the City

Illinois has one of the largest data center pipelines in the country, behind only Virginia and Texas by the number of projects planned or under construction in early 2026. Nearly all of the state's colocation is in the Chicago metro, but the new large campuses are spreading west of it.

Local rules are tightening

Aurora ended a 180-day moratorium in March 2026 by adopting strict siting rules for new data centers, including noise caps and 1,500-foot setbacks for generators and chillers from homes. Existing facilities are unaffected.

Incentives on hold

Illinois paused new agreements under its data center sales tax incentive from July 1, 2026, as covered above. Confirm the status before a deployment depends on it.

Where to look

For anything from a cabinet to a few megawatts, the market is the city and the O'Hare corridor. For trading, Aurora.

How to Find Colocation Space in Chicago

1

Choose the submarket before the building

Downtown for networks and counterparties, the O'Hare corridor for space, power and density, Aurora only for latency-critical trading. Your office location is the weakest reason to choose any of them.

2

Send the requirement before contacting any operator

Once an operator has it directly, it usually will not work through an advisor. Sent through us, it goes to the facilities that fit, and we negotiate the terms for you.

3

Ask for capacity with a date

With about 20 MW available and no 5 MW block expected in 2026, the useful question is what exists on your date at your density, not what is advertised as coming.

4

Compare five-year totals

Escalator, cross-connects, setup, remote hands and power above the commitment decide the bill. In Chicago, cross-connects can change which building is cheapest.

5

Plan for growth now

Expansion rights on adjacent space are scarce and worth negotiating at signing, because large contiguous blocks are scarce and most new supply is preleased before it delivers.

Five Mistakes Chicago Buyers Make

1. Assuming Chicago is the cheap option

For many requirements it now prices at or above Northern Virginia. Budget from current rates, not old reputations.

2. Starting the search too late

With ComEd timelines past 2032 for large projects, the capacity that exists today is what there is.

3. Paying for Aurora when downtown would do

Only the most latency-sensitive strategies need to sit next to CME's matching engine.

4. Comparing rates instead of totals

Cross-connects and remote hands can reverse which facility is cheapest.

5. Counting on an incentive that has paused

The state data center investment program stopped new agreements in July 2026. Confirm before relying on it.

How We Find Space in Chicago

You send the requirement: cabinets or kilowatts, density, submarket preference, compliance and the date. We find the Chicago space that can serve it, including space that is not advertised, compare the options on five-year cost and terms, and negotiate the contract before you sign. The provider you choose pays us from its channel budget, so it costs you nothing and your rate is not marked up. If Chicago is not the right market for the requirement, we say so and price the one that is. How a data center broker works.

Frequently Asked Questions

How much does colocation cost in Chicago?

For a 250 to 500 kW requirement, CBRE put Chicago asking rates at $200 to $230 per kW per month in early 2026, the highest of North America's four core data center markets and up 14.7 percent in a year. Rates for 10 MW and up rose 9.7 percent in the first half of 2026. Downtown carrier hotels and Aurora sit at the top of the range, and O'Hare corridor campuses usually offer more space and power per dollar.

What is the best data center in Chicago?

It depends on the workload. For carrier density and cloud on-ramps, 350 East Cermak downtown, owned by Digital Realty, with Equinix, CoreSite and QTS nearby. For larger deployments and AI, the O'Hare corridor campuses in Elk Grove Village and Franklin Park. For latency-critical trading, CyrusOne Aurora, home of CME's matching engine.

Who are the main Chicago data center providers?

Digital Realty, Equinix, CoreSite, QTS, DataBank, TierPoint, Flexential, Aligned, Prime, STACK and CyrusOne. Each is strongest for a different kind of workload, from interconnection downtown to wholesale in the O'Hare corridor and trading in Aurora.

Which colocation providers operate in downtown Chicago?

Digital Realty at 350 East Cermak and 600 South Federal, Equinix with CH1, CH2 and CH4 inside 350 East Cermak, CoreSite with CH1 and CH2, and QTS on S. Ashland Avenue.

Which Chicago data centers offer low-latency access to CME?

CME's matching engine runs in CyrusOne's Aurora data center, so the lowest latency is a deployment in Aurora. Downtown buildings such as 350 East Cermak connect to Aurora over low-latency fiber and microwave routes and suit strategies that need CME access without the lowest possible latency.

Is there colocation space available in Chicago?

Some. About 20 MW was available across the metro in early 2026, a 2.2 percent vacancy rate, and CBRE reports no contiguous block of 5 MW or more available. Cabinets and small suites are easier to find than large blocks.

Which Chicago colocation providers suit a small deployment of one to ten racks?

Operators that sell retail colocation by the cabinet, downtown or in the near suburbs: Equinix, CoreSite, Digital Realty, DataBank, TierPoint and Flexential. Small deployments have the most choice, because Chicago's scarcity is in large contiguous blocks.

Where should AI and high-density deployments go in Chicago?

Mostly the O'Hare corridor, where newer campuses have the power and cooling dense racks need; some downtown halls support higher density in specific rooms. Power availability is the limit, so start with which hall can deliver your density on your date.

Is there HIPAA-compliant colocation in Chicago?

Yes. Several Chicago operators support HIPAA-compliant deployments and sign business associate agreements. The right choice depends on the documentation, audit cadence and BAA scope you need, confirmed against your requirements before any commitment.

Do Chicago data centers hold Uptime Institute Tier certification?

Some do, but most describe themselves as Tier III-equivalent or concurrently maintainable, a design claim rather than a certificate. CoreSite CH2, for example, is listed as Tier III-equivalent. Ask the operator for the certificate and check it against Uptime Institute's registry if certification matters to you.

What are the alternatives to Equinix in Chicago?

Digital Realty and CoreSite downtown for carrier and cloud connectivity, QTS and DataBank for enterprise colocation, and Aligned, Prime and STACK in the O'Hare corridor for larger deployments. For trading, CyrusOne in Aurora. Equinix remains strong for dense interconnection.

Is Chicago or Northern Virginia better for colocation?

They serve different needs. Northern Virginia has the most cloud density and even tighter vacancy; Chicago offers a central network position, the CME derivatives ecosystem and a strong enterprise base. Rates for 250 to 500 kW are close in both.

Why is Chicago data center power so constrained?

ComEd's delivery timelines for large new projects run into 2032 or later, and it now requires 10-year letters of credit backing transmission revenue on projects of 50 MW or more. That is why new development is moving to sites with large power positions outside the suburbs.

Do you place colocation in Chicago?

Yes, across the major Chicago operators through formal channel partnerships. Send the requirement and you'll hear back within 24 hours. We find the facilities that fit, benchmark the pricing, and negotiate the contract before you sign. The provider you choose pays us, so it costs you nothing.

Where are the data centers in Illinois?

Mostly in the Chicago metro: downtown at 350 East Cermak, along the O'Hare corridor in Elk Grove Village, Franklin Park, Itasca and Northlake, and in the western suburbs at Aurora and Westmont. Farther west, Meta operates a data center in DeKalb. Illinois has one of the three largest data center pipelines in the US.
