U.S. Data Center Colocation Market Size to Reach USD 85.18 Billion by 2031, Backed by USD 461.62 Billion in Cumulative Investments | Arizton

Arizton forecasts the U.S. data center colocation market will grow from USD 43.71B in 2025 to USD 85.18B by 2031 (11.76% CAGR) and attract nearly USD 462B in cumulative 2026–2031 investments, driven by hyperscale/AI-ready expansion. The report expects AI-dedicated capacity to almost triple over the next 5–6 years, increasing demand for high-density GPU/ASIC/FPGA infrastructure and substantially higher power and cooling capacity. Sustainability is also becoming a competitive differentiator, with operators targeting carbon-neutral targets by 2030 and increasingly using PPAs, on-site renewables, and storage to support AI load growth.

Analysis

The market is probably underappreciating the split between “more data-center spend” and “equity holders capturing the spread.” The scarce asset is not just land, but usable megawatts, interconnects, and permitting; that favors operators with existing footprints and balance-sheet capacity to pre-fund power and cooling, while punishing smaller developers if financing costs stay elevated. High-density AI loads also shift dollars toward the picks-and-shovels layer — electrical gear, thermal management, backup power — which should compound faster than pure colocation revenue.

Near term, the first-order reaction should be muted because this is already a crowded AI infrastructure theme; the real catalyst is 1-3 quarters of leasing, backlog conversion, and capex guidance, not the headline market-size number. Over 6-18 months, the key risk is overbuild in Virginia/Texas/Ohio: if too much capacity comes online at once, pricing power per MW can compress even while aggregate investment rises. That would favor cash-flow-rich incumbents over story stocks and force discount-rate scrutiny on highly levered developers.

Contrarian read: the consensus is treating all colocation spend as equally accretive, but a large share of the value accrues to utilities, grid equipment, and cooling vendors, not necessarily to the REIT equity. If power delivery or sustainability approvals slip, the investment cycle can elongate without collapsing demand. The thesis is falsified if we see rising vacancy, weaker preleasing, or capex inflation outpacing rent escalators in the next two reporting cycles.

Key Decisions for Investors

• Long EQIX on 2-3% pullbacks; 6-12 month hold. Best risk/reward in the group because it monetizes scarce interconnects and power with lower execution risk. Falsify on two consecutive quarters of slower leasing or shrinking spread between revenue growth and capex.
• Pair trade: long EQIX / short APLD for 3-6 months. This expresses quality over speculative buildout as the market rewards cash conversion rather than capacity announcements. Risk: APLD secures a marquee anchor tenant plus non-dilutive funding, which would squeeze the short.
• Overweight VRT and ETN versus pure data-center REIT beta for the next 1-3 quarters. High-density AI racks should keep orders for cooling, switchgear, and power-management systems ahead of revenue recognition in the operators. Falsify if backlog/order growth decelerates or lead times normalize faster than expected.
