Thailand Data Center Colocation Market Size, Share & Forecast to 2035

The Thailand Data Center Colocation Market covers the revenue that third-party operators earn from data centers in Thailand by leasing space, power and cooling to tenants: retail colocation (racks, cages and private suites), wholesale colocation (whole halls and build-to-suit capacity for cloud, platform and AI tenants), interconnection and managed services sold inside colocation facilities. DC Market Insights values the Thailand Data Center Colocation Market at USD 305.16 million in 2025 and forecasts USD 4.85 billion by 2035, a CAGR of 31.86%. The 2025 value is built from leased capacity: about 97 MW of occupied colocation IT load on average through 2025, priced at about USD 290 per kW per month for retail space and power in Bangkok and USD 175 per kW per month for wholesale halls, plus interconnection and managed services, gives about USD 3.15 million of revenue per occupied MW. Wholesale colocation is the fastest-growing segment at 42.68% a year because the new campuses in Thailand are pre-leased by hyperscale and platform tenants, and the Eastern Economic Corridor (EEC) is the fastest-growing region at 63.19% a year because most of that wholesale capacity is being built in Chonburi and Chachoengsao.

Executive Summary

The Thailand Data Center Colocation Market size was valued at USD 99.07 million in 2020, reached USD 305.16 million in 2025, and is anticipated to reach USD 4.85 billion by 2035, at a CAGR of 31.86% during the forecast period.

Thailand Data Center Colocation Market Size 2025	USD 305.16 Million
Thailand Data Center Colocation Market, CAGR	31.86%
Thailand Data Center Colocation Market Size 2035	USD 4.85 Billion

The Thailand Data Center Colocation Market grew at 25.23% a year between 2020 and 2025, and 2025 added 31.3% over 2024 in the DC Market Insights model as Bangkok vacancy fell and new halls filled. Operational data center capacity in Bangkok reached 113 MW in 2025, with colocation vacancy of 17.6%, and 134 MW in the first half of 2026, up 19%, according to Cushman and Wakefield. Revenue growth peaks at 54.5% in 2028, when the wholesale campuses now under construction are handed over and leased, and slows to 16.0% by 2035 as the leased base becomes large.

The supply wave is already visible. Bangkok under-construction capacity rose 148% to 859 MW in the first half of 2026, putting Thailand second in Asia Pacific behind Malaysia, and the Thailand Board of Investment (BOI) received 36 data center projects in 2025 with a combined investment value exceeding USD 23.1 billion (THB 728 billion), according to the BOI’s 2025 investment release. DC Market Insights expects colocation operators to build about 52% of new national capacity from 2029, taking colocation capacity from about 147 MW at the end of 2025 to 2,607 MW at the end of 2035.

Market Scope: What Does the Thailand Data Center Colocation Market Cover?

The Thailand Data Center Colocation Market is the annual revenue of multi-tenant data center operators in Thailand, valued in current US dollars, with 2025 as the base year and forecasts to 2035. DC Market Insights sizes it at USD 305.16 million in 2025.

Included. Retail colocation (single racks, partial racks, cages and private suites, usually under 1 MW per customer), wholesale colocation (halls, floors and build-to-suit buildings leased to cloud, platform, AI and large enterprise tenants), power and cooling charges billed with the space, interconnection (cross-connects, internet exchange ports and cloud on-ramps) and managed services sold in the facility (remote hands, monitoring, security and disaster recovery).

Excluded. Capacity that hyperscalers, telecom operators, banks and government agencies build and run for themselves, public cloud and software revenue, tenant-owned IT equipment, construction spend and land.

How the segments fit together. Revenue is counted where the facility is located. The colocation type, service, end-user, enterprise-size and tier splits each re-cut the same USD 305.16 million, and the regional split allocates it across four Thai sub-markets. The capacity base is shared with the DC Market Insights Thailand Data Center Market and Thailand Data Center Infrastructure Market models, which measure spending on building and equipping the same halls.

Market Drivers: What Drives the Thailand Data Center Colocation Market?

Falling vacancy in Bangkok, cloud regions that lease capacity from local operators and data residency rules drive the Thailand Data Center Colocation Market, which DC Market Insights expects to grow 32.4% in 2026.

Bangkok Colocation Vacancy Fell from 24% to 16% in Six Months

Bangkok colocation vacancy dropped from 24% in the second half of 2024 to 16% by the end of the first half of 2025, according to Cushman and Wakefield data reported by W.Media, and stood at 17.6% for 2025 as a whole while operational capacity grew to 113 MW. Bangkok carrier-neutral colocation had reached roughly 105 MW, up from 59 MW in December 2023, according to a Mondaq legal briefing. In the DC Market Insights model, average occupied colocation capacity in Thailand rose from about 73 MW in 2024 to about 97 MW in 2025, which is why revenue grew faster than capacity.

Cloud Regions Lease Capacity from Thai Colocation Operators

Amazon Web Services (AWS) launched its Asia Pacific (Thailand) Region in January 2025 with three Availability Zones and plans to invest more than USD 5 billion in Thailand. Microsoft has partnered with CP Group, and True IDC will serve as one of the data centers for Microsoft’s Thai cloud region; True IDC’s Thailand data center is scalable up to 60 MW and capable of housing high-density compute infrastructure, according to Data Center Dynamics. Evolution Data Centres has pre-leased the first 12 MW phase of its TH01 facility in Bangkok to a tier 1 global hyperscaler on a multi-year contract. Wholesale colocation, which serves these tenants, grows 42.68% a year in the DC Market Insights model, the fastest rate of any colocation type.

Data Residency and Sector Rules Keep Workloads in Thailand

Domestic enterprises are choosing the path of least regulatory resistance under Thailand’s Personal Data Protection Act (PDPA), and Bank of Thailand (BOT) cloud-outsourcing rules apply to regulated financial institutions, according to Mondaq. Banking, financial services and insurance (BFSI) customers spend USD 45.45 million on colocation in Thailand in 2025, 14.9% of the market, by DC Market Insights estimates. Government and public sector customers add USD 28.31 million, 9.3% of the market, as state agencies move systems into colocation in the DC Market Insights model.

Market Trends: How Is Colocation in Thailand Changing?

Pre-leased hyperscale halls, AI-ready capacity and green power financing are reshaping the Thailand Data Center Colocation Market: DC Market Insights estimates the wholesale share of revenue rises from 34.0% in 2025 to 74.9% in 2035.

Hyperscale Campuses of 100 MW Move to the EEC

Digital Edge lists its BKK1 facility in Chonburi as a 100 MW AI-ready hyperscale data center ready in the fourth quarter of 2026, and USD 880 million of green loan financing was announced in May 2026 for the Digital Edge and B.Grimm Power joint venture’s 100 MW BKK Data Center Campus. Bridge Data Centres was approved for a THB 24.6 billion project supporting an IT load of 134 MW in Chonburi, and Skyline Data Center and Cloud Services for a THB 46 billion project supporting 200 MW in Chachoengsao, according to Thailand Business News. DC Market Insights places 52% of new colocation capacity in the EEC between 2026 and 2030.

AI-Ready Halls Become a Colocation Product

True IDC launched an AI hyperscale data center in Bangkok in May 2025 equipped with over 20 megawatts of power capacity, and in March 2026 broke ground on a 250 MW AI hyperscale data center in the EEC at a cost of THB 77 billion, with the first phase scheduled to be operational by 2027. Tier IV colocation revenue grows 40.91% a year in the DC Market Insights model, the fastest tier, as AI tenants ask for concurrently maintainable power and liquid cooling.

Interconnection Concentrates in Bangkok

The Bangkok Neutral Internet Exchange (BKNIX) lists 71 peers and 4.4 Tbps of total port capacity on PeeringDB, and is present in seven Thai facilities including STT Bangkok 1, NTT Bangkok 2 and Telehouse Bangkok. Interconnection revenue is USD 17.31 million in 2025, 5.7% of the market, and USD 14.89 million of it is earned in the Bangkok Metropolitan Region, by DC Market Insights estimates.

Market Challenges: What Holds the Thailand Data Center Colocation Market Back?

Power prices, new grid rules and the risk that 859 MW of construction arrives faster than tenants are the main constraints DC Market Insights sees on a market growing 31.86% a year.

Power Costs of THB 5 to 6 per kWh Squeeze Margins

Data centers are expected to pay around THB 5 to 6 (USD 0.15 to 0.18) per kWh under Thailand’s new tariff structure, according to Eco-Business, against a general rate of THB 3.95 per unit for May to August 2026 set by the Energy Regulatory Commission (ERC). Power is billed with space in most Thai colocation contracts, so DC Market Insights holds wholesale prices close to flat in real terms, from USD 175 per kW per month in 2025 to USD 169.82 in 2030.

Grid Guarantees and Commercial-Operation Deadlines

Local media have reported a proposed transmission-capacity guarantee of THB 4.5 million (USD 135,771) per MW, and developers may have to demonstrate commercial operations within five to seven years or risk losing allocated capacity, according to Eco-Business. DC Market Insights treats slower grid connection as the main downside in its low scenario, with colocation completions 25% below the base case.

Supply Could Outrun Leasing

Bangkok under-construction capacity of 859 MW in the first half of 2026 compares with 134 MW in operation, and the Bangkok pipeline reached 2,084 MW, up 99%, according to Cushman and Wakefield. National colocation occupancy dips from about 74% at the end of 2025 to about 67% in 2027 in the DC Market Insights model as new halls open part-empty, before recovering to about 83% by 2035.

Market Opportunities: Where Are the New Revenue Pools in the Thailand Data Center Colocation Market?

Wholesale halls for platform and AI tenants and colocation outside Bangkok form the largest new revenue pools: DC Market Insights estimates wholesale colocation at USD 3.63 billion and EEC colocation at USD 2.05 billion in 2035.

Platform Tenants Need Leased Capacity at Scale

The BOI approved a TikTok System (Thailand) project valued at THB 842 billion, or approximately USD 25 billion, in May 2026, the largest of the projects in that round, according to Thailand Business News. Projects of this size need wholesale halls faster than tenants can build their own, and DC Market Insights expects the IT and telecom segment, which includes cloud and platform tenants, to grow 36.74% a year to USD 3.51 billion by 2035.

Thai Energy Groups Build Colocation Platforms

GULF expects to generate THB 100 million of revenue per 1 MW from the GSA data center, its joint venture with Singtel and AIS, which was set to begin commercializing 6.4 MW, targeting 25 MW by the end of 2025 and 50 MW afterward, Kaohoon International reported in June 2025. GULF has set an ambition to reach 2,000 MW of data center capacity within three to five years, including the 38 MW GSA 02 facility slated for 2027. Other central and eastern provinces, where land and power are available near Bangkok, grow 37.65% a year to USD 410.21 million by 2035 in the DC Market Insights model.

Pricing: How Much Does Colocation Cost in Thailand?

Retail colocation in Bangkok costs about USD 290 per kW per month in 2025 and wholesale colocation about USD 175 per kW per month, by DC Market Insights estimates, with power and cooling included in both.

Price (USD per kW per month, Bangkok)	2025	2030	2035
Retail colocation, space and power	290.00	317.06	346.64
Wholesale colocation, space and power	175.00	169.82	173.24
Revenue per occupied MW, all streams (USD million a year)	3.15	2.40	2.40

Public price lists give a check on the retail rate. A Bangkok provider lists a 42U full rack from THB 42,000 per month, a 20U half rack from THB 24,000 and a 9U quarter rack from THB 12,000, and a second provider hosted at INET facilities lists a 10U rack at THB 20,000 per month. At a DC Market Insights exchange-rate assumption of THB 33.50 per US dollar, a full rack at THB 42,000 is about USD 1,254 per month. For wholesale and blended revenue, GULF’s expectation of THB 100 million of revenue per MW at the GSA data center equals about USD 2.99 million per MW (implicitly annual), close to the USD 3.15 million per occupied MW in the DC Market Insights model for 2025. Wholesale halls set outside Bangkok are priced 5% to 8% below Bangkok in the model, and blended revenue per MW falls from USD 3.15 million in 2025 to USD 2.40 million in 2030 because wholesale leases take a larger share of capacity.

Standards and Regulation: Which Rules Shape Colocation in Thailand?

Four sets of rules shape colocation in Thailand: BOI promotion conditions, data protection and sector rules, grid and energy regulation and design standards such as TIA-942.

BOI promotion conditions. The BOI states that conditions for data center promotion include requirements related to data center construction and service standards, the Power Usage Effectiveness (PUE), and efficient water management measures. Its top incentive tier requires a PUE not exceeding 1.3 and GPU-enabled or advanced computing capability, and ISO/IEC 27001 certification is required before a company exercises its corporate income tax (CIT) exemption, according to Mondaq.

Data protection and sector rules. The PDPA, BOT cloud-outsourcing rules for regulated financial institutions and National Cyber Security Committee (NCSC) standards for critical information infrastructure all favor hosting in Thai facilities that can show certified controls, according to Mondaq.

Grid and energy regulation. A new data center screening framework covering electricity consumption, grid stability and water management, which the regulator is reportedly preparing, is expected to take effect around the fourth quarter, according to Eco-Business in August 2026, which also reported that Thailand had previously been developing a 2,000 MW Direct PPA pilot.

Design standards. According to the Telecommunications Industry Association (TIA), TIA-942-C was published in May 2024 and covers data centers including single tenant enterprise data centers and multi-tenant data centers. Tier III facilities earn USD 240.10 million of Thai colocation revenue in 2025, 78.7% of the market, by DC Market Insights estimates.

Market Segmentation: Which Segment Leads the Thailand Data Center Colocation Market?

Retail colocation leads the Thailand Data Center Colocation Market with 66.0% of 2025 revenue, and space and power leads services with 87.4%. Wholesale colocation is the fastest-growing segment at 42.68% a year because hyperscale and platform tenants pre-lease whole halls in the new campuses, while retail demand from Thai enterprises grows 19.70% a year.

By Colocation Type: Retail Leads with 66.0%

Colocation type	2025 (USD million)	Share 2025	2035 (USD billion)	CAGR 2025-2035
Retail Colocation	201.28	66.0%	1.22	19.70%
Wholesale Colocation	103.88	34.0%	3.63	42.68%

Retail and wholesale colocation each used about 48 MW of leased capacity in 2025 in the DC Market Insights model, but retail earns about 1.7 times as much per kW. By 2035 wholesale tenants occupy about 1,772 MW against about 243 MW for retail, and wholesale becomes 74.9% of revenue.

By Service: Space and Power Leads with 87.4%

Service	2025 (USD million)	Share 2025	2035 (USD billion)	CAGR 2025-2035
Space and Power	266.71	87.4%	4.47	32.58%
Managed and Value-Added Services	21.14	6.9%	0.21	25.81%
Interconnection	17.31	5.7%	0.16	25.18%

Interconnection and managed services are mostly sold to retail customers, so they grow with retail colocation rather than with wholesale halls.

By End User: IT and Telecom Leads with 50.3%

End user	2025 (USD million)	Share 2025	2035 (USD billion)	CAGR 2025-2035
IT and Telecom	153.61	50.3%	3.51	36.74%
BFSI	45.45	14.9%	0.37	23.49%
Government and Public Sector	28.31	9.3%	0.27	25.39%
Media and Entertainment	22.27	7.3%	0.22	25.94%
Healthcare	13.12	4.3%	0.13	25.60%
Others	42.40	13.9%	0.34	23.05%

IT and telecom includes cloud providers, digital platforms, content networks and telecom operators. Others covers retail, manufacturing, energy, logistics and education.

By Enterprise Size: Large Enterprises Lead with 74.9%

Large enterprises, including hyperscale and platform tenants, spend USD 228.67 million on colocation in Thailand in 2025 and USD 4.43 billion by 2035, a CAGR of 34.51%. Small and medium enterprises (SMEs) spend USD 76.49 million (25.1%), rising to USD 413.34 million by 2035 at 18.38% a year, almost all of it in retail racks and cages.

By Tier Level: Tier III Leads with 78.7%

Tier III facilities earn USD 240.10 million in 2025 and USD 3.60 billion by 2035, growing 31.09% a year. Tier IV, at USD 36.88 million (12.1%), grows fastest at 40.91% a year as AI halls are designed for higher resilience, while Tier I and II rooms, at USD 28.18 million (9.2%), grow 14.53% a year.

DC Exclusive: The Bangkok vs EEC Colocation Revenue Matrix

At USD 143.13 million in 2025, retail space and power in the Bangkok Metropolitan Region is the single largest cell of the matrix and 46.9% of all Thai colocation revenue.

2025, USD million	Retail space and power	Wholesale space and power	Interconnection	Managed services	Total
Bangkok Metropolitan Region	143.13	85.70	14.89	18.18	261.90
Other Central and Eastern Provinces	10.91	3.48	1.09	1.32	16.80
Eastern Economic Corridor	4.41	9.63	0.56	0.70	15.30
North, Northeast and South	7.89	1.56	0.77	0.94	11.16
Total	166.34	100.37	17.31	21.14	305.16

Bangkok earns 54.7% of its colocation revenue from retail space and power because its older multi-tenant buildings serve banks, enterprises and network operators rack by rack. The EEC earns 62.9% from wholesale halls because its first colocation facilities, such as NTT’s 12 MW Bangkok 3 at Amata City in Chonburi, are built for large tenants. By 2035 the EEC earns USD 2.05 billion, almost as much as Bangkok at USD 2.12 billion.

The matrix is a DC Market Insights model, not a survey of operator revenue. It is built from 70 inputs: 22 capacity cohort values (11 years of national completions and colocation shares), 4 legacy capacity values by region, 8 occupancy values, 8 retail-share values by region, 8 price curves by type and region and 20 service and regional allocation weights, checked against GULF’s revenue per MW and published rack prices. The method is explained on our research methodology page.

Regional Insights: Which Region Leads the Thailand Data Center Colocation Market?

The Bangkok Metropolitan Region leads with 85.8% of 2025 revenue. In the Thailand Data Center Colocation Market, the Eastern Economic Corridor is the fastest-growing region at 63.19% a year because most new wholesale campuses are being built in Chonburi and Chachoengsao.

Bangkok Metropolitan Region Leads with 85.8% Share

The Bangkok Metropolitan Region, including Samut Prakan, earns USD 261.90 million in 2025 and USD 2.12 billion by 2035, a CAGR of 23.28%. STT GDC’s three Bangkok facilities bring its total capacity in the district to 42 MW, NTT’s Bangkok 1 in Bang Na offers 1.6 MW, and Telehouse Bangkok offers 9.5 MVA of capacity in a 9,000 sqm carrier-neutral building. Evolution Data Centres’ TH01 in Bangkok adds 12 MW in the fourth quarter of 2026 and a second 40 MW phase in the second quarter of 2027.

Other Central and Eastern Provinces Hold 5.5% Share

Other central and eastern provinces earn USD 16.80 million in 2025 and USD 410.21 million by 2035, a CAGR of 37.65%, as operators look for land and grid connections outside the Bangkok core and the EEC estates.

Eastern Economic Corridor Holds 5.0% Share

The Eastern Economic Corridor earns USD 15.30 million in 2025 and USD 2.05 billion by 2035, growing 63.19% a year to 42.3% of the market. NTT broke ground on its Bangkok 4 campus in Chonburi in July 2026, backed by a 100 MW power purchase agreement (PPA) with B.Grimm Power and with energization expected in the second quarter of 2027, and the Digital Edge, Bridge Data Centres, Skyline and True IDC campuses follow.

North, Northeast and South Hold 3.7% Share

The North, Northeast and South earn USD 11.16 million in 2025 and USD 264.62 million by 2035, a CAGR of 37.24%, mostly from retail colocation and edge sites run by telecom operators for provincial enterprises and government agencies.

Forecast Scenarios: How Could the 2035 Forecast Change?

The Thailand Data Center Colocation Market reaches USD 4.85 billion by 2035 in the base case, with a range of USD 3.53 billion to USD 5.72 billion across the low and high scenarios.

Scenario	Assumption from 2026	2035 (USD billion)	CAGR 2025-2035
Low	Colocation completions 25% below base; wholesale prices 8% lower	3.53	27.72%
Base	Colocation operators build 52% of new national capacity from 2029; wholesale price near USD 170 per kW per month	4.85	31.86%
High	Colocation completions 15% above base; wholesale prices 5% higher	5.72	34.05%

The low case reflects grid guarantees and power costs that delay EEC campuses; the high case assumes hyperscale and platform tenants lease rather than build most of their new Thai capacity.

Methodology: How We Built the Thailand Data Center Colocation Market Model

DC Market Insights built the Thailand Data Center Colocation Market bottom-up from leased capacity. Colocation capacity starts at about 112 MW at the end of 2024 (98 MW in the Bangkok Metropolitan Region) and adds 11 annual cohorts from 2025 to 2035, each a share of the national completions in the Thailand Data Center Market model (37% of 95 MW in 2025, 55% of 170 MW in 2026, falling to 52% from 2029), split across four sub-regions. Occupancy rises from 76% on the legacy base in 2024 to 88% by 2028, and new cohorts are 45% leased in their opening year, 75% in the next year and 88% in the year after. Revenue is average occupied MW multiplied by price: USD 290 per kW per month for retail space and power and USD 175 for wholesale in Bangkok in 2025, with regional discounts, plus interconnection and managed services as a share of space and power revenue. The total was split by 2 colocation types, 3 services, 6 end-user groups, 2 enterprise sizes, 3 tier levels and 4 regions, and every split sums to the market total. The result was checked top-down against Cushman and Wakefield’s 113 MW of Bangkok operational capacity and 17.6% vacancy in 2025 (the model has 116 MW in the Bangkok Metropolitan Region), against 134 MW in the first half of 2026, and against GULF’s THB 100 million of revenue per MW, which equals about USD 2.99 million per MW against USD 3.15 million in the model.
