The Case for Carrier-Dense Colocation in a Supply-Constrained Market

The Market Has Fundamentally Shifted

The U.S. data center colocation market is in the midst of a structural transformation. After nearly 15 years of declining lease rates and abundant supply, the market has turned. According to datacenterHawk's 2026 market intelligence, average colocation rates have increased 17% over the past five years, and available capacity in established, carrier-rich facilities is increasingly difficult to find on short timelines.

The scale of the demand driving this shift is difficult to overstate. Global data center spending is forecast to reach approximately $600 billion in 2026, driven by AI-optimized infrastructure and hyperscaler investment. The U.S. colocation market alone is expected to grow by 16.5% this year to reach nearly $47 billion, according to market research compiled by GlobeNewswire. And this growth is not evenly distributed — it is concentrating in facilities that can offer what AI-era tenants actually require: power, density, and connectivity.

Why Interconnection Is the Differentiating Asset

Not all colocation is created equal. The most valuable data centers in this environment are not simply buildings with power and cooling — they are nodes in an established connectivity ecosystem. Carrier-neutral facilities with deep interconnection inventories offer a set of capabilities that new builds cannot replicate quickly or cheaply.

S&P Global's research identifies interconnection as a persistent and growing driver of colocation demand. As AI inferencing workloads scale, the ability to exchange traffic directly with cloud platforms, content delivery networks, and enterprise networks becomes a direct performance input. Facilities with 15, 20, or more carriers on-net eliminate the latency and cost of traversing public internet exchange points. They serve as aggregation hubs for an entire regional network ecosystem — a role that cannot be simply duplicated by constructing a new building nearby.

MarketsandMarkets notes that carrier-neutral providers hold a structural competitive advantage in this environment precisely because they can offer flexible interconnection across multiple networks. This is particularly relevant as enterprises increasingly adopt hybrid IT strategies that require low-latency data exchange between on-premises infrastructure, colocation environments, and multiple public cloud platforms.

Supply Constraints Are Structural, Not Cyclical

One of the most consequential dynamics in today's market is the recognition that capacity constraints in primary data center markets are not temporary bottlenecks — they are structural realities. Utility interconnection queues in Northern Virginia exceed 4.2 gigawatts. In Phoenix, data center applications surpassed 1.8 GW in 2025 alone. Average wait times for a grid connection in primary data center markets now exceed four years, according to JLL's 2026 Global Data Center Outlook.

These constraints have a direct implication for enterprises and network operators evaluating their colocation options: providers that already hold established capacity and deep carrier ecosystems in these markets are among the few that can offer immediate access — without the multi-year wait that new builds require. The second consequence is that investment toward markets where power availability, permitting pathways, and utility relationships are more navigable — including a growing number of mid-size U.S. metros that combine population density with less saturated infrastructure environments.

For enterprises and network operators evaluating their colocation strategy, this environment creates a practical constraint: waiting for new supply to emerge in saturated primary markets is no longer a reliable plan. The development pipeline is measured in years, not months. Organizations that need capacity now — with the carrier density and interconnection depth to support production workloads — need partners who are already established in the markets that matter to them.

The Value of Established Ecosystems in an Era of Scarcity

Against this backdrop, the value of established carrier-neutral colocation environments becomes clearer. A facility that already anchors the connectivity fabric of a regional market — where traffic from dozens of networks converges, where enterprises have built their interconnection strategies, where the meet-me room is a functioning hub rather than an aspiration — can offer something a new build simply cannot: immediate access to a live, proven ecosystem.

New builds can add power and square footage. What they cannot offer is the accumulated network density — the carriers already on-net, the cross connects already in place, the cloud on-ramps already active — that takes years to build and that enterprises depend on from day one of their deployment. When a production workload requires direct peering with a specific carrier or cloud platform, the question is not whether that connection can eventually be provisioned. It is whether it exists today.

The broader market trend is converging on this conclusion. Demand for dense, low-latency interconnection is growing as more services require direct peering and partner ecosystems. Location choice, as DataBank's 2026 market forecast notes, increasingly depends on ecosystem density. The facilities that built those ecosystems years ago are best positioned to serve the infrastructure demands of the next decade — not just because of what they have, but because of how quickly they can put it to work.

About Radius DC

Radius DC operates carrier-neutral data centers in Phoenix, Miami, Denver, and Atlanta. Each facility is built around a deep interconnection ecosystem — multiple carriers on-net, direct cloud on-ramps, and meet-me room infrastructure that enterprises and network operators can access immediately. In markets where new capacity is measured in years, Radius DC offers something increasingly rare: established presence, proven ecosystems, and the ability to support production workloads from day one.
