Wholesale Colocation Market Size, Share & Forecast to 2035

The Wholesale Colocation Market is valued at USD 51.12 billion in 2026 and is projected to reach USD 158.10 billion by 2035, up from USD 38.88 billion in 2025, a CAGR of 15.06% from 2025 to 2035 (DC Market Insights estimate). Wholesale colocation money now moves on pre-leasing: cloud and artificial intelligence (AI) tenants sign 10- to 25-year leases for whole halls and campuses before the shell is finished, and Meta Platforms alone reported about USD 355.73 billion of leases that had not yet commenced on 30 September 2026 (Source: Meta Form 10-Q, Q3 2026). On the supply side, Digital Realty signed 143.6 MW of leases above 1 MW in the third quarter of 2026 at USD 275 of base rent per kilowatt (kW) per month (Source: Digital Realty, 29 October 2026). The 2025 receipt is 24,000 MW of leased wholesale capacity in billing × USD 135 per kW-month × 12 months = USD 38.88 billion; liquid-cooled AI halls grow fastest at 27.62% a year, and the Middle East and Africa is the fastest region at 25.23% because gigawatt campuses in Saudi Arabia and the United Arab Emirates (UAE) start from a small leased base.

Wholesale colocation grew 24.57% a year from 2020 to 2025 as leased wholesale capacity in billing rose from 9,000 MW to 24,000 MW, led by hyperscale cloud expansions in Northern Virginia, Dallas, Phoenix, Frankfurt, Tokyo and Johor. Growth eases to 15.06% after 2025 because grid connections, not tenant demand, set the pace: Texas alone had more than 438,000 MW of large loads asking for a connection in June 2026, nearly 90% of them data centers (Source: Electric Reliability Council of Texas (ERCOT), June 2026).

Market Scope: What Counts as Wholesale Colocation?

Wholesale colocation covers USD 38.88 billion of rent paid in 2025 for leases of 1 MW or more of critical IT capacity in third-party data centers.

Included

• Turnkey data halls leased in blocks of 1 MW and more, with power and cooling delivered by the landlord
• Build-to-suit campuses developed for one tenant under a long lease
• Powered shells, where the landlord delivers the building and grid power and the tenant fits out the hall
• AI campus leases signed by GPU (graphics processing unit) cloud providers and model developers

Excluded

• Retail colocation by the rack or cage below 1 MW and interconnection fees, covered in the Data Center Colocation Market
• Electricity passed through to tenants at cost, which can add 40% to 60% to a tenant’s bill
• Data centers that hyperscalers build and own themselves, and the sale or leaseback of whole buildings
• GPU cloud services sold by the hour or by contract, such as IREN’s AI cloud contracts

How the Segments Fit Together

Each dimension sums to the same total every year: lease type describes what the landlord delivers, end user describes the tenant, lease size describes the contract block and cooling design describes the hall. Hyperscale cloud providers pay 62.00% of 2025 rent.

Why Do Wholesale Colocation Market Estimates Differ?

DC Market Insights puts wholesale colocation at USD 51.12 billion in 2026, and estimates that count power pass-through, retail colocation or hyperscale self-build come out far larger.

Wider definitions add the electricity that tenants pay through the landlord, the rack-and-cage retail market, interconnection fees, or the capital cost of new campuses. Others count only the hyperscale segment and leave out enterprise and AI cloud tenants. This edition counts rent on leases of 1 MW or more, so a large enterprise or a mid-size AI developer taking 2 MW is in scope; large enterprises paid 14.00% of 2025 rent.

Element	In this report	Why
Base rent on 1 MW-plus leases	Yes, USD 38.88 billion in 2025	Core wholesale revenue
Retail racks and cages below 1 MW	No	Priced per rack, sold with interconnection
Power pass-through	No	Billed at cost, not landlord revenue margin
Hyperscale self-build	No	No lease and no rent
GPU cloud services	No	Sold as compute, not as space and power

Market Drivers: Why Are Wholesale Colocation Leases Getting Bigger?

Three forces push wholesale colocation rent from USD 38.88 billion in 2025 to USD 104.40 billion in 2030: hyperscale lease commitments, AI campus contracts and repricing of older leases.

Meta’s USD 355.73 Billion of Leases Not Yet Commenced

Hyperscalers sign wholesale leases years before move-in. Meta Platforms reported about USD 355.73 billion of operating and finance leases that had not yet commenced on 30 September 2026, starting between late 2026 and 2036 with terms up to 30 years (Source: Meta Form 10-Q, Q3 2026). Meta also narrowed its 2026 capital spending outlook to USD 135 to 145 billion (Source: Meta, 21 October 2026), and Amazon expects about USD 220 billion of cash capital spending in 2026 (Source: Amazon, 29 October 2026). DC Market Insights estimates hyperscale cloud providers pay USD 24.11 billion of wholesale rent in 2025.

AI Campus Leases from Applied Digital, Cipher Mining and TeraWulf

Former bitcoin-mining sites with large grid connections now lease whole campuses to AI tenants. Applied Digital reported about 1,410 MW of contracted critical IT across five campuses on 31 May 2026, worth about USD 36 billion over 15-year base terms, including a 300 MW Delta Forge 1 lease to an investment-grade hyperscaler for about USD 7.5 billion (Source: Applied Digital, 27 July 2026). Cipher Mining signed about USD 5.5 billion over 15 years with Amazon Web Services (AWS) for 300 MW (Source: Cipher Mining, 3 November 2025). AI and GPU cloud providers grow from USD 4.67 billion of wholesale rent in 2025 to USD 42.69 billion by 2035, DC Market Insights estimates.

Renewal Spreads of 11.8% and Record Backlogs

Older wholesale leases signed at lower rents are repricing. Digital Realty raised cash rents on renewals signed in the third quarter of 2026 by 11.8% and reported a record backlog of USD 2.5 billion of annualized base rent at 100% share (Source: Digital Realty, 29 October 2026). Iron Mountain priced new and expansion data center leases at USD 205 per kW-month in the second quarter of 2026 with an 11.8% cash mark-to-market (Source: Iron Mountain, 5 August 2026). DC Market Insights lifts the average in-place wholesale rent from USD 135 per kW-month in 2025 to USD 150 in 2030.

Market Trends: How Is Wholesale Colocation Leasing Changing?

Wholesale colocation is moving to bigger blocks and denser halls, with liquid-cooled AI halls rising from USD 8.55 billion in 2025 to USD 98.02 billion by 2035.

Hyperscaler Credit Backstops Behind Neocloud Leases

Landlords now lease to AI clouds with a hyperscaler guarantee behind the rent. Google backstopped USD 1.4 billion of Fluidstack’s lease obligations at Cipher Mining’s 168 MW Barber Lake site, a roughly USD 3 billion 10-year contract (Source: Cipher Mining, 25 September 2025), and USD 1.8 billion at TeraWulf’s Lake Mariner site (Source: TeraWulf, 14 August 2025). The backstop lets a 2- or 3-year-old tenant sign a 10-year lease, which explains why AI and GPU cloud providers rise from 12.00% to 27.00% of wholesale rent by 2035.

Gigawatt Land Banks: Digital Realty’s 1 GW Indianapolis Site

Wholesale landlords are buying land for campuses of a size that only hyperscalers built before. Digital Realty reported about 1.5 GW under construction and land near Indianapolis for more than 1 GW and near Charlotte for up to 600 MW of IT capacity (Source: Digital Realty, 29 October 2026). Iron Mountain held 684.2 MW for development beside 160.2 MW under development that was 71.2% pre-leased (Source: Iron Mountain, 5 August 2026). Leases above 100 MW grow at 22.97% a year, the fastest lease-size band.

Wholesale REITs Move Capital Through Joint Ventures

Real estate investment trusts (REITs) fund campuses with partners to keep debt low. Equinix agreed a joint venture of more than USD 15 billion with GIC and the Canada Pension Plan Investment Board for over 1.5 GW of new United States xScale capacity (Source: Equinix, 1 October 2024), and Keppel DC REIT completed Tokyo DC 4 and 5 for JPY 168.4 billion on 1 October 2026 (Source: Keppel DC REIT, 23 October 2026). DC Market Insights expects build-to-suit campuses to rise from 33.00% to 48.00% of wholesale rent.

Market Challenges: What Holds Back Wholesale Colocation Supply?

Grid queues and local permit rules limit how fast wholesale colocation capacity can reach billing, which is why DC Market Insights grows billed capacity by 13.48% a year rather than at the pace of tenant requests.

Grid Queues: 438,000 MW of Large Loads in Texas

ERCOT reported more than 438,000 MW of proposed large-load demand in June 2026, nearly 90% of it from data centers, and moved loads above 75 MW to batch studies (Source: ERCOT, June 2026). Texas Senate Bill 6 of 2025 set a 75 MW large-load threshold and a study fee of at least USD 100,000 (Source: Texas Legislature, 2025). Campuses that cannot show a confirmed connection date cannot sign take-or-pay leases, so DC Market Insights holds 2026 billed capacity at 30,000 MW.

Permit Pauses: Loudoun County and Ireland

The largest wholesale hub has tightened its rules. Loudoun County, Virginia, made data centers a conditional use in former by-right zones in March 2025 and voted 7-1-1 in September 2026 for a pause on new legislative data center applications while it writes Phase 2 rules (Source: Loudoun County, 16 September 2026). Ireland’s Commission for Regulation of Utilities (CRU) requires new data centers to bring on-site or nearby generation or storage matching their import capacity (Source: CRU, December 2025). Europe grows at 12.98% a year, below the global rate.

Market Opportunities: Where Will New Wholesale Colocation Rent Come From?

The largest new wholesale colocation rent pools are AI campuses above 100 MW, worth USD 55.34 billion by 2035, and new hubs in the Middle East and India.

Liquid-Cooled AI Campuses Above 100 MW: USD 55.34 billion by 2035

Leases above 100 MW rise from USD 7.00 billion in 2025 to USD 55.34 billion by 2035. Galaxy Digital delivered 133 MW of critical IT at its Helios campus to CoreWeave under a 15-year lease, within 526 MW contracted and more than USD 1.2 billion of expected average annual revenue (Source: Galaxy Digital, 5 August 2026). Landlords with grid power in hand can sign such leases at USD 140 to 190 per kW-month, DC Market Insights estimates.

Saudi Arabia, the UAE and India: USD 9.80 billion by 2035

Saudi Arabia grows 27.94% a year and India 22.65% a year, the two fastest countries in the top 12. In Abu Dhabi, G42 announced a 5 GW UAE-US AI campus (Source: G42, 15 May 2025), and in Malaysia the Malaysian Investment Development Authority (MIDA) recorded RM385.7 billion of data-center-related investment from 2021 to the first half of 2026 (Source: MIDA, 14 September 2026). Together Saudi Arabia and India add USD 8.71 billion of wholesale rent between 2025 and 2035.

Pricing Analysis: How Much Does Wholesale Colocation Cost per kW?

Wholesale colocation averaged USD 135 per kW-month of in-place rent in 2025, power excluded, rising to USD 155 by 2035 (DC Market Insights estimate).

Year	Average in-place rent (USD per kW-month)	Leased capacity in billing (MW)	Market size (USD million)
2020	120.00	9,000	12,960.00
2025	135.00	24,000	38,880.00
2030	150.00	58,000	104,400.00
2035	155.00	85,000	158,100.00

Public anchors bracket the average: Digital Realty’s leases above 1 MW signed in the third quarter of 2026 carried USD 275 of base rent per kW-month, Iron Mountain priced new leases at USD 205, and long AI campus leases disclosed in Securities and Exchange Commission (SEC) filings imply USD 102 to 190 per kW-month. The average sits lower than new-lease prices because most rent in billing comes from leases signed between 2018 and 2023 at USD 100 to 130.

Standards and Regulation: Which Rules Shape Wholesale Colocation Leases?

At least eight rules shape where wholesale colocation can be built and leased in 2026, from Texas grid rules to Singapore’s capacity allocation.

Market Segmentation: Which Lease Types and Tenants Lead Wholesale Colocation?

Turnkey data halls lead wholesale colocation with USD 20.22 billion in 2025, while build-to-suit campuses grow fastest at 19.45% a year.

By Lease Type

Turnkey halls stay the largest type because most hyperscale expansions add 2 to 20 MW at existing campuses; build-to-suit gains as AI tenants contract whole sites.

Lease Type	2025 (USD million)	Share 2025	2035 (USD million)	CAGR 2025-2035
Turnkey Data Halls	20,217.60	52.00%	63,240.00	12.08%
Build-to-Suit Campuses	12,830.40	33.00%	75,888.00	19.45%
Powered Shells	5,832.00	15.00%	18,972.00	12.52%

By End User

Hyperscale cloud providers pay most of the rent, and AI and GPU cloud providers grow fastest at 24.78% a year.

End User	2025 (USD million)	Share 2025	2035 (USD million)	CAGR 2025-2035
Hyperscale Cloud Providers	24,105.60	62.00%	86,955.00	13.69%
Large Enterprises	5,443.20	14.00%	15,810.00	11.25%

By Cooling Design

Liquid-cooled AI halls overtake air-cooled halls in wholesale rent around 2032, because new accelerator racks need direct liquid cooling.

Cooling Design	2025 (USD million)	Share 2025	2035 (USD million)	CAGR 2025-2035
Air-Cooled Halls	30,326.40	78.00%	60,078.00	7.08%
Liquid-Cooled AI Halls	8,553.60	22.00%	98,022.00	27.62%

DC Exclusive: Wholesale AI Lease Ledger, 9 Contracts, 2,712 MW and USD 102 to 190 per kW-Month

The Wholesale AI Lease Ledger is a DC Market Insights model built on 9 inputs: nine wholesale AI leases disclosed in SEC filings between February 2025 and July 2026 cover 2,712 MW of critical IT and imply USD 102 to 190 per kW-month.

DC Market Insights derives each implied rent as contract value divided by critical IT kW and months of term; the totals can include escalators, so the figures are an estimate, not a quoted rent. Shorter 10-year contracts price higher per month than 15-year ones, and the AWS lease at USD 102 is the lowest because the tenant carries the best credit.

Campus	Landlord / tenant	Critical IT (MW)	Term	Contract value	Implied USD per kW-month	Disclosed
Polaris Forge 1, North Dakota	Applied Digital / CoreWeave	250	15 years	USD 7.0 billion	156	May 2025
Delta Forge 1, Louisiana	Applied Digital / investment-grade hyperscaler	300	15 years	USD 7.5 billion	139	Jul 2026
Delta Forge 2, Louisiana	Applied Digital / undisclosed	210	15 years	USD 5.2 billion	138	Jul 2026
Barber Lake, Texas	Cipher Mining / Fluidstack (Google backstop)	168	10 years	USD 3.0 billion	149	Sep 2025
AWS lease	Cipher Mining / Amazon Web Services	300	15 years	USD 5.5 billion	102	Nov 2025
Lake Mariner, New York	TeraWulf / Fluidstack (Google backstop)	200	10 years	USD 3.7 billion	154	Aug 2025
Abernathy, Texas	TeraWulf joint venture / Fluidstack	168	25 years	USD 9.5 billion	188	Oct 2025
Helios, Texas	Galaxy Digital / CoreWeave	526	15 years	USD 1.2 billion a year	190	Aug 2026
Six sites incl. Denton, Texas	Core Scientific / CoreWeave	590	12 years	USD 10.0 billion	118	Feb 2025

The ledger’s capacity-weighted midpoint of about USD 150 per kW-month is the rent DC Market Insights applies to new AI campus leases from 2026, above the USD 135 average of all wholesale rent in billing in 2025.

Regional Insights: Which Region Leads Wholesale Colocation?

North America leads wholesale colocation with USD 20.22 billion in 2025, and the Middle East and Africa grows fastest at 25.23% a year.

12	Saudi Arabia	Middle East and Africa	349.92	4,110.60	27.94%

Malaysia ranks seventh with USD 1.01 billion in 2025, above Singapore, because Johor campuses lease the capacity Singapore cannot allocate; Singapore’s DC-CFA2 released only 200 MW in August 2026.

Forecast Scenarios: How Big Could Wholesale Colocation Be by 2035?

Wholesale colocation reaches USD 158.10 billion by 2035 in the base case, with a range of USD 124.32 billion to USD 194.40 billion.

Scenario	2035 (USD million)	Leased capacity in billing 2035 (MW)	Average rent 2035 (USD per kW-month)	CAGR 2025-2035
Low	124,320.00	70,000	148.00	12.33%
Base	158,100.00	85,000	155.00	15.06%
High	194,400.00	100,000	162.00	17.46%

The low case assumes grid queues hold billed capacity to 70,000 MW; the high case assumes AI campuses keep signing above 100 MW and grid connections speed up after the ERCOT batch process.

Research Methodology: How the Wholesale Colocation Model Works

DC Market Insights sizes wholesale colocation bottom-up as leased capacity in billing × average in-place rent × 12 months: 24,000 MW × USD 135 per kW-month × 12 = USD 38.88 billion in 2025.

Leased capacity in billing rises from 9,000 MW in 2020 to 85,000 MW in 2035, about 20.7% of the 116 GW installed data center IT base in 2025 and 27.3% of 311 GW in 2035. Lease type, end user, lease size, cooling design, region and country splits are DC Market Insights shares that sum to the total every year. Three bound checks:

• Ceiling 1: USD 51.12 billion of 2026 wholesale rent equals about 9% of the roughly USD 560 billion of 2026 capital spending guided by Amazon, Alphabet and Meta.
• Ceiling 2: average in-place rent of USD 135 per kW-month sits below the USD 205 to 275 at which Iron Mountain and Digital Realty priced new leases in 2026.
• Floor: disclosed annual wholesale revenue of Digital Realty’s above-1 MW bookings, Iron Mountain’s data center segment (about USD 1.05 billion a year), Core Scientific (about USD 1.8 billion annualized) and Galaxy Digital (USD 1.2 billion) is far below USD 38.88 billion, as expected for four of more than 30 landlords.
