Who are the top investors in data centers?
Whether you're building or investing in the data center market, our report covers everything you need to know: the players, the money, and what's coming next.
Summary
Blackstone is currently the world's leading financial investor in data centers, followed by KKR, Brookfield, BlackRock's Global Infrastructure Partners and Macquarie Asset Management. Blackstone leads our assessment through its combination of established operating assets, major acquisitions and a development pipeline that few competitors can match.
Blackstone reports approximately $165 billion in existing and under-construction data center assets, alongside another $160 billion in planned development. Its QTS platform has increased leased capacity roughly fifteenfold since 2021, making actual expansion, rather than announced investment ambitions, a central part of its leadership.
KKR is Blackstone's closest competitor among diversified investment managers. Its portfolio spans CyrusOne, Compass Datacenters, ST Telemedia Global Data Centres and several other operators, giving it a broader geographic footprint than many of its rivals.
Brookfield is the most interesting challenger from an infrastructure integration perspective. Its program targeting up to $100 billion in AI infrastructure combines data centers with electricity, land and computing equipment, although much of that amount remains prospective rather than deployed capital.
BlackRock's Global Infrastructure Partners has demonstrated remarkable acquisition capacity through the $40 billion Aligned Data Centers transaction. That deal made it a major force in the industry, but the enterprise value belongs to a consortium and cannot be counted entirely as BlackRock's own investment.
Macquarie has arguably demonstrated the strongest platform-building track record. AirTrunk's enterprise valuation grew more than eightfold during its ownership period, while its subsequent Aligned exit contributed to approximately $56 billion in combined exit enterprise valuations across the two businesses.
The investor landscape is becoming more specialized. SoftBank gained exposure to DigitalBridge's infrastructure investment platform, while Blue Owl helped finance Meta's approximately $27 billion Hyperion development through a joint venture in which its managed funds received 80% ownership.
Pension funds and sovereign wealth funds are no longer peripheral participants. CPP Investments took a controlling stake in atNorth, while GIC, MGX and other institutional investors have committed capital to major data center transactions and partnerships.
The biggest financial sponsors still operate on a different spending scale from Amazon, Microsoft, Alphabet and Meta. Those four technology companies collectively spent approximately $165.1 billion on property and equipment in a single quarter of 2026, although that includes considerably more than data center property.
Capital availability is increasingly only part of the equation. Data center financing now relies heavily on debt in some markets, while securing grid connections, electricity capacity, permits and suitable development sites has become a decisive competitive advantage.
Our conclusion is that Blackstone has the strongest proven position today, KKR has assembled the most compelling diversified challenge, and Brookfield offers substantial future upside through integrated infrastructure development. The next ranking changes will depend less on billion-dollar announcements and more on which investors actually secure power, deliver operational capacity and generate attractive returns.

Why are investors spending so much money on data centers right now?
Data centers are attracting some of the world's largest investment firms because AI and cloud computing are creating a huge demand for new facilities, and the cost of building them keeps climbing.
According to JLL's 2026 Global Data Center Outlook, more than $300 billion went into global data center acquisitions, joint ventures and equity investments between 2020 and 2025.
Annual transaction volume reached approximately $80 billion in 2025, compared with $73 billion in 2024 and $28 billion in 2023. In just two years, the amount of money changing hands almost tripled.
The market has also become much more expensive to enter. JLL found that average data center construction costs increased from $7.7 million per megawatt in 2020 to $10.7 million in 2025, before the cost of servers and other computing equipment. For an AI facility, that additional equipment can cost another $25 million per megawatt.
Individual developments can now require billions of dollars, and even established operators struggle to finance expansion entirely on their own.
Blackstone, KKR, Brookfield and BlackRock have all increased their involvement, but they are approaching the opportunity differently. Some buy operating data center companies, others finance new developments, and some are bringing electricity generation and computing infrastructure into the same investment strategy.
Who are the biggest data center investors today?
Blackstone currently leads our ranking of financial investors in data centers, followed by KKR, Brookfield, BlackRock's Global Infrastructure Partners and Macquarie Asset Management.
Blackstone has the strongest combination of existing assets, major acquisitions and future development commitments. The firm reported a $165 billion global data center platform in its 2026 midyear investment commentary, plus approximately $160 billion in additional planned development.
KKR is another heavyweight. Its June 2026 investor presentation disclosed $43 billion of committed capital across 26 digital infrastructure investments, including data centers, fiber and wireless businesses.
Brookfield announced a program targeting up to $100 billion in AI infrastructure investment, while a consortium involving BlackRock's Global Infrastructure Partners and MGX completed the $40 billion acquisition of Aligned Data Centers.
These figures measure different things. Blackstone's numbers describe asset and development scale, KKR's cover committed capital across several digital infrastructure categories, and Brookfield's represent a future investment program.
We have therefore ranked investors according to their actual data center involvement, the size of their operating platforms, completed transactions and demonstrated ability to finance new capacity.
| Investor | Major data center exposure | Publicly disclosed scale | Assessment |
|---|---|---|---|
| Blackstone | QTS, AirTrunk | $165B platform; $160B pipeline | Overall leader |
| KKR | CyrusOne, STT GDC, Compass, Nxera | $43B committed across digital infrastructure | Leading diversified investor |
| Brookfield | Data centers, AI factories, power infrastructure | Up to $100B AI infrastructure program | Major growth challenger |
| BlackRock / GIP | Aligned Data Centers | $40B consortium acquisition | Leading megadeal investor |
| Macquarie Asset Management | Former owner of AirTrunk and Aligned; VIRTUS, Netrality | ~$56B combined exit enterprise valuations | Leading platform builder |
| SoftBank / DigitalBridge | Vantage, DataBank, AIMS and other investments | $3.1B DigitalBridge acquisition | Major specialized investor |
| Blue Owl Capital | Meta Hyperion and other financing structures | ~$27B Hyperion development joint venture | Leading structured financing investor |
| CPP Investments | atNorth, AirTrunk, Equinix partnerships | ~$1.3B atNorth equity commitment | Major pension investor |
| GIC | Equinix xScale partnerships and other data center investments | Multibillion-dollar joint ventures | Major sovereign investor |

Is Blackstone really the world's largest data center investor?
Blackstone has the strongest publicly documented claim to being the world's largest financial investor in data centers, and its expansion since acquiring QTS shows why.
Blackstone purchased QTS Data Centers for approximately $10 billion in 2021, before the AI investment boom transformed the industry.
In its 2026 midyear investment perspectives, Blackstone reported that QTS's leased capacity had increased roughly fifteenfold since the acquisition. That is a remarkable expansion for a business already operating at institutional scale.
The firm then moved into Asia-Pacific through AirTrunk. In 2024, a Blackstone-led consortium agreed to buy the company at an enterprise valuation exceeding A$24 billion, approximately US$16 billion.
AirTrunk brought established hyperscale facilities and a substantial development pipeline across major Asian markets. Blackstone could immediately add regional exposure to its North American data center business.
The scale of the combined strategy is now unusually large. Blackstone reported approximately $165 billion in existing and under-construction data center assets, alongside a further $160 billion development pipeline.
The additional pipeline is prospective and cannot be treated as completed investment. Still, few competitors have publicly documented a comparable combination of owned infrastructure and planned expansion.
Blackstone also expects to invest or commit roughly $100 billion across its data center portfolio by the end of 2026.
Has KKR become Blackstone's biggest competitor in data centers?
KKR is currently Blackstone's closest competitor among the large diversified investment managers, particularly when we look at the number of major data center platforms it has assembled.
KKR's June 2026 investor presentation identified six important data center platforms: CyrusOne and Compass Datacenters in the Americas, Nxera and ST Telemedia Global Data Centres in Asia, and Gulf Data Hub and Global Technical Realty across Europe and the Middle East.
That gives KKR exposure to several regional markets with different electricity conditions, customers and development opportunities.
Its biggest recent move came in February 2026, when KKR and Singtel announced plans to acquire the remaining 82% of ST Telemedia Global Data Centres for S$6.6 billion.
The deal implied an enterprise valuation of approximately S$13.8 billion, or US$10.9 billion.
KKR and Singtel had already invested S$1.75 billion in STT GDC in 2024. During the period between the transactions, the company's development pipeline grew from approximately 1.4 gigawatts to more than 1.7 gigawatts.
The new transaction would give KKR approximately 75% ownership and Singtel the remaining 25%.
KKR has also been expanding beyond data center property. Its June presentation separately identified $33 billion of committed capital across 36 power infrastructure investments.
Those investments cannot automatically be linked to KKR's data center facilities, but the combination gives the firm considerable experience in two industries that increasingly depend on each other.
Blackstone still leads on disclosed data center platform value. KKR, meanwhile, has built a wider collection of independently managed operators across several continents.

In our research about data centers, we turn what is vague and complex into simple, useful visuals. Market maps like this one show you at a glance where every startup stands.
Is BlackRock catching up with Blackstone through major data center acquisitions?
BlackRock has become one of the biggest buyers of data center infrastructure, especially after participating in the industry's largest completed acquisition, but it has not yet demonstrated a larger directly controlled data center portfolio than Blackstone.
Its position changed substantially after acquiring Global Infrastructure Partners in October 2024.
The combination brought together infrastructure investment operations managing approximately $170 billion at the time. That figure included energy, transportation and other infrastructure, but it gave BlackRock a much larger platform for investing in physical assets.
The decisive data center transaction came in July 2026, when the Artificial Intelligence Infrastructure Partnership, MGX and BlackRock's GIP completed their acquisition of Aligned Data Centers.
The deal valued Aligned at approximately $40 billion and included another $5 billion in committed growth capital.
At closing, Aligned reported 51 campuses and more than 6.4 gigawatts of operating and planned capacity across North and South America.
Data Center Dynamics described the transaction as the largest acquisition in the industry's history. It also shows how much larger data center deals have become.
Before the AI boom, the $10 billion acquisition of QTS in 2021 was already considered enormous. CyrusOne followed at approximately $15 billion in 2022, while AirTrunk reached roughly $16 billion in 2024.
Aligned's $40 billion valuation exceeded the combined enterprise values of the QTS and CyrusOne acquisitions.
There is an important distinction when comparing BlackRock with Blackstone. BlackRock participated through a consortium, so the $40 billion enterprise value cannot be attributed entirely to its own investment.
Blackstone still leads on disclosed data center platform scale, while BlackRock and GIP have established themselves among the most powerful buyers of large infrastructure businesses.
The table compares transaction enterprise values where available. These should not be confused with the buyer's equity contribution.
| Buyer | Data center company | Deal value | Year |
|---|---|---|---|
| AIP, MGX and BlackRock GIP consortium | Aligned Data Centers | ~$40B | 2026 |
| Blackstone-led consortium | AirTrunk | ~$16B | 2024 |
| KKR and GIP | CyrusOne | ~$15B | 2022 |
| KKR and Singtel | STT GDC | ~$10.9B enterprise value | 2026 announced |
| DigitalBridge and IFM consortium | Switch | ~$11B | 2022 |
| Blackstone | QTS Data Centers | ~$10B | 2021 |
| CPP Investments and Equinix consortium | atNorth | ~$4B | 2026 |
| DigitalBridge-led investor group | Vantage Data Centers | ~$3.5B majority investment | 2020 |
Could Brookfield become the world's biggest data center investor?
Brookfield is one of the strongest candidates to challenge Blackstone, particularly if its plan to combine data centers with electricity infrastructure produces operating facilities at the scale it is targeting.
In November 2025, Brookfield launched a $100 billion AI infrastructure investment program alongside NVIDIA and the Kuwait Investment Authority.
The program includes the Brookfield Artificial Intelligence Infrastructure Fund, which launched with approximately $5 billion in commitments and a target of $10 billion in equity.
The larger $100 billion figure represents potential investment capacity supported by partners, co-investors and financing. It covers electricity, land, data centers and computing equipment.
Brookfield is approaching the market from several directions because large AI facilities need much more than server buildings.
One example is the proposed redevelopment of the former uranium enrichment site in Paducah, Kentucky. Brookfield discussed the project during its 2026 second-quarter earnings commentary, describing a potential campus with more than 2 gigawatts of computing capacity and up to $100 billion in private investment.
That remains a proposed development, with considerable work required before it can operate.
Still, the approach gives Brookfield an interesting position. The company already invests extensively in electricity generation and other infrastructure, which could help it develop sites where access to sufficient power is the biggest obstacle.
Brookfield could narrow the gap with Blackstone substantially, but we would need to see more completed projects and operating capacity before moving it into first place.
If you want more recent data on this point, please see our latest data center market report.
In our market report about data centers, we always try to gather several sources and make estimates that make sense, so you can work with solid numbers.
Did Macquarie make more money from data centers than its rivals?
Macquarie Asset Management has one of the strongest records of buying, growing and selling major data center companies, although its publicly disclosed transactions do not reveal exactly how much profit it made.
AirTrunk is the clearest example.
In 2020, a consortium led by Macquarie and including PSP Investments bought an 88% stake in AirTrunk at a valuation of approximately A$3 billion.
Four years later, the business was sold to a Blackstone-led consortium at an enterprise valuation exceeding A$24 billion.
The company's valuation had increased more than eightfold.
That growth came alongside substantial business expansion. AirTrunk increased from five facilities and approximately 450 megawatts of capacity to 11 sites and more than 1.8 gigawatts during the ownership period.
Macquarie followed a similar path with Aligned Data Centers.
It first invested in Aligned in 2018, increased its involvement in 2020 and eventually sold the company through its managed infrastructure funds in the $40 billion transaction completed in July 2026.
Across AirTrunk and Aligned, the combined exit enterprise valuations reached approximately $56 billion.
That's an extraordinary amount of asset value associated with two investment exits. However, it is not the same as Macquarie's realized profit because both businesses raised additional capital and carried financial obligations during their development.
Macquarie remains active through other data center investments, including VIRTUS and Netrality, and announced a South Korean data center joint venture with Gabia in March 2026.
Is SoftBank now a major data center investor after buying DigitalBridge?
SoftBank has become a much more important data center investor following its completed acquisition of DigitalBridge, one of the best-known specialist managers in digital infrastructure.
The transaction closed in September 2026 for approximately $3.1 billion, according to SoftBank's official announcement.
DigitalBridge continues operating as a separately managed platform under Marc Ganzi, but it is now controlled by SoftBank.
This gives SoftBank access to an investment business with experience backing data center operators such as Vantage Data Centers, DataBank and AIMS.
DigitalBridge has also invested in fiber networks, wireless towers and other infrastructure, so its total investment portfolio extends well beyond data centers.
The acquisition is notable because SoftBank is already deeply involved in AI through investments and commercial partnerships across the technology industry.
Owning DigitalBridge adds an investment management business focused on the physical infrastructure that those technologies need.
It also gives SoftBank a different way to participate in AI growth. Instead of relying entirely on returns from technology companies, it can benefit from investments in the facilities and networks supporting their operations.
The acquisition price should not be interpreted as the value of every infrastructure asset managed by DigitalBridge. SoftBank purchased the investment management company, while its managed funds and portfolio companies have their own ownership arrangements.

Why is Blue Owl investing billions in Meta's data centers?
Blue Owl Capital has become an important data center investor by helping Meta finance enormous facilities without requiring Meta to provide all the development capital itself.
In October 2025, Meta and funds managed by Blue Owl announced a joint venture to develop the Hyperion data center campus in Louisiana.
Meta's official announcement put the total development costs for the campus buildings and long-lived infrastructure at approximately $27 billion.
Blue Owl-managed funds received an 80% ownership interest in the joint venture, while Meta retained 20%.
The funds managed by Blue Owl made an initial cash contribution of approximately $7 billion. Meta also received a distribution of about $3 billion from the partnership.
This was a different type of investment from buying an established data center operator.
Meta remains heavily involved in constructing and managing the facilities, and it agreed to lease the completed buildings from the joint venture.
Blue Owl provides capital and takes ownership exposure to infrastructure developed around a major technology customer's requirements.
The arrangement allows Meta to pursue large-scale expansion while allocating a substantial share of the property investment to an institutional partner.
The transaction includes contractual protections, including a residual value guarantee provided by Meta under certain circumstances.
Are pension funds and sovereign wealth funds becoming major data center investors?
Pension funds and sovereign wealth funds are now major sources of data center capital, with some taking controlling ownership stakes rather than investing exclusively through external managers.
CPP Investments provides one of the clearest recent examples.
In September 2026, CPP Investments and Equinix completed their acquisition of Nordic data center operator atNorth, following an agreement initially announced at an enterprise valuation of approximately $4 billion.
The final ownership structure differed from the original plan.
CPP Investments committed approximately $1.3 billion for a controlling stake of around 51%. Equinix committed approximately $895 million for roughly 34%, while Partners Group reinvested approximately $260 million for a 10% stake. The remaining ownership stayed with internal stakeholders.
atNorth operated eight data centers across the Nordic region, with several more facilities under development.
The transaction also involved a financing package of approximately $4.1 billion, underwritten by European and Canadian lenders to support the acquisition and further expansion.
CPP Investments had already gained data center exposure through AirTrunk and partnerships with Equinix. Canada's PSP Investments was also part of the earlier AirTrunk ownership group.
Sovereign investors are following a similar path.
Abu Dhabi's MGX participated in the Aligned acquisition, while Kuwait Investment Authority became a founding investor in Brookfield's AI infrastructure fund. Singapore's GIC has participated in large Equinix data center joint ventures.
These institutions can provide patient capital for projects that take years to develop and may generate income over decades.
In our report covering the data center market, we look at what the winners do differently, so you can learn from the best instead of guessing.
Are Amazon, Microsoft, Google and Meta spending more on data centers than investment firms?
Amazon, Microsoft, Alphabet and Meta spend vastly more on computing infrastructure collectively than any single financial investment manager, making them the most important capital spenders in the broader data center industry.
According to company filings compiled by Compute Terminal, the four companies spent approximately $165.1 billion in cash on property and equipment during the second quarter of 2026.
That compares with approximately $88.2 billion in the same quarter of 2025, an increase of roughly 87%.
Amazon accounted for approximately $54.2 billion of the more recent quarterly expenditure, followed by Alphabet at $44.9 billion, Microsoft at $35.8 billion and Meta at $30.1 billion.
Together, these companies increased their quarterly spending by approximately $76.9 billion over just one year.
That additional expenditure alone was almost twice the enterprise value of Aligned Data Centers, the largest completed acquisition discussed earlier.
There is an important accounting distinction. Hyperscaler capital expenditure includes servers, processors, networking equipment, buildings and other assets, rather than exclusively data center real estate. Some equipment acquired through leases also falls outside these cash expenditure figures.
The investment objectives differ as well.
Blackstone and KKR generally seek returns from infrastructure businesses that serve customers. Amazon, Microsoft, Google and Meta are primarily building capacity for their own products, cloud services and AI operations.
The overlap is substantial because these technology companies are also among the biggest customers of externally owned data centers.
If we include all companies spending money on data center infrastructure, the hyperscalers belong at the top of the discussion. For a ranking of financial investors acquiring and financing third-party data center assets, Blackstone remains our first choice.
Are banks providing more money to data centers than private equity firms?
Debt financing now supplies most of the capital raised by data center operators in some major markets, meaning banks and credit investors are far more important than acquisition rankings might suggest.
The Reserve Bank of Australia's September 2026 research provides a useful comparison.
Australian data center operators raised at least A$35 billion during 2026 through the period examined, compared with A$24 billion during 2025.
Between 2020 and 2024, the annual average had been only A$4.6 billion.
Fundraising during the partial 2026 period was already more than seven times the earlier annual average.
Approximately 85% of the capital raised in 2026 came through debt. The Reserve Bank estimated that debt represented roughly 60% to 80% of comparable US data center funding.
In Australia, syndicated lending accounted for approximately A$25 billion of new funding during the period, while corporate bond issuance reached around A$5 billion.
US financing has relied more heavily on bonds and securitization. JLL reported that US data center asset-backed securities issuance exceeded $17 billion in 2025, almost doubling from the preceding year.
This borrowing supports a business model that often has predictable contracted revenue.
Large customers may agree to lease data center capacity before construction begins. Once lenders are satisfied with the customer, the project economics and the underlying assets, they can provide substantial debt financing.
That also creates risks. Large amounts of borrowing make projects more sensitive to financing costs, construction delays and changes in the value of the underlying facilities.
In our research about data centers, we don't want to repeat what boring consulting reports say. Instead, we show you the real and latest market signals that matter.
Does having access to electricity now matter more than having money?
Access to electricity is becoming one of the biggest advantages a data center investor can have, especially now that many large financial institutions are ready to finance new projects.
JLL estimates that global data center capacity could roughly double to around 200 gigawatts by 2030.
Supporting that growth would require almost 100 gigawatts of additional capacity and potentially $3 trillion in investment across facilities, electrical infrastructure and computing equipment.
But construction money does not solve every problem.
A developer may have customers willing to sign leases and investors prepared to finance a campus, yet still face long delays obtaining grid connections.
JLL's 2026 outlook identifies speed of access to electricity as the leading factor in selecting new data center locations, ahead of construction costs and proximity to customers.
This helps explain the different investment strategies emerging across the industry.
Brookfield is trying to bring electricity, land and computing infrastructure together through large development programs.
Blackstone places considerable emphasis on securing power availability, land and zoning permissions before major projects proceed.
KKR has significant investments in both digital infrastructure and electricity-related assets, giving the firm experience with the financing and development requirements of each industry.
The ability to obtain electricity can also make an existing data center platform more valuable.
A company with secured power connections, permits and future development sites may be attractive even before all its planned facilities have been built.
If you want more recent data on this point, please see our latest data center market report.
Which data center investors are best positioned to benefit from AI?
Blackstone, KKR and Brookfield are currently the strongest large financial investors for exposure to AI-driven data center growth, although each has a different advantage.
Blackstone leads in established platform scale. QTS has expanded dramatically under its ownership, while AirTrunk gives the firm access to fast-growing Asian computing markets.
KKR has built a more geographically diversified collection of operators. This gives it opportunities across the Americas, Europe, Asia and the Middle East, where cloud demand, land availability and electricity markets differ considerably.
Brookfield offers a more integrated infrastructure strategy, combining investment in data centers with land, power generation and other essential facilities.
BlackRock and GIP have shown that they can organize enormous acquisitions with institutional partners. Blue Owl has demonstrated another valuable capability: bringing external capital into hyperscaler developments without taking over day-to-day data center operations.
Macquarie also deserves attention because its history with AirTrunk and Aligned demonstrates how much value an investor can create by expanding a platform and selling it to larger institutions.
The biggest risk across all these strategies is paying too much for expected AI growth.
A facility with confirmed power, a financially strong customer and a long-term lease is fundamentally different from a proposed campus waiting for grid access and future tenants.
Investors also face rising construction costs. JLL calculated that global data center construction costs grew by roughly 7% annually between 2020 and 2025, putting pressure on the economics of projects that take several years to complete.
Learning from others' mistakes is the cheapest lesson there is. In our market report about data centers, we look at what broke startups before you, so you don't repeat it.
Who are the top investors in data centers overall?
Blackstone is currently the world's leading financial investor in data centers in our assessment, with KKR second and Brookfield, BlackRock's Global Infrastructure Partners and Macquarie Asset Management completing the strongest group.
Blackstone's leadership comes from the combination of large operating platforms, a major global development pipeline and demonstrated growth after acquisition.
KKR follows because it has built an extensive international portfolio covering several large data center businesses. Its diversification and power infrastructure experience make it a serious competitor for future projects.
Brookfield could eventually challenge both firms if its integrated AI infrastructure program delivers the scale it is targeting.
BlackRock and GIP are already among the most powerful buyers of large platforms, while Macquarie has shown an exceptional ability to build data center businesses that attract major institutional acquirers.
SoftBank's completed acquisition of DigitalBridge has also made it a more important participant in specialist digital infrastructure investing.
Blue Owl stands out in financing partnerships, with its Meta Hyperion transaction showing how financial institutions can help fund increasingly expensive hyperscaler developments.
Pension funds and sovereign wealth funds, including CPP Investments, GIC and MGX, are supplying additional long-term equity capital.
We should also keep the role of Amazon, Microsoft, Alphabet and Meta in perspective. Their infrastructure spending is much larger collectively than the amounts deployed by any individual financial sponsor, and their demand drives a substantial share of the market.
Blackstone leads among financial investors today, but the next leaders will be determined by their ability to secure electricity, bring new capacity online and earn attractive returns on increasingly expensive developments. The firms announcing the largest investment plans still have to prove they can deliver them.

Sources and methodology
This analysis examines who currently leads financial investment in data centers. There is no standardized global ranking covering ownership, deployed capital, operating capacity and future development commitments, so we assessed the evidence across five dimensions: existing portfolio scale, investment activity, operational expansion, geographic reach and future development capabilities.
For each dimension, we examined recent acquisitions, investor disclosures, financing arrangements, capacity expansion and independent industry research. We then compared the strongest evidence across investors rather than relying on a single transaction, investment announcement or headline figure. The ranking gives particular weight to completed acquisitions, established operating platforms, measurable expansion and demonstrated ability to finance new capacity.
We kept different measures of investment scale separate. Enterprise valuations describe entire businesses rather than the equity invested by individual buyers. Assets under management can include infrastructure outside the data center sector, while development pipelines and announced investment programs represent future opportunities rather than capital already deployed. Hyperscaler capital expenditure and project debt financing were examined separately from financial investors' direct equity exposure.
We also considered the practical constraints behind future expansion, especially grid connectivity, electricity availability, development permissions and construction costs. These factors help distinguish investors with ambitious plans from those with a realistic path to delivering operational infrastructure. Our final ranking reflects the convergence of scale, demonstrated execution and the ability to fund and complete future developments.
Key sources for market conditions and Blackstone's position include JLL's 2026 Global Data Center Outlook, Blackstone's 2026 Mid-Year Investment Perspectives, Blackstone's QTS acquisition announcement and its AirTrunk acquisition announcement.
For large institutional investors and platform transactions, we used KKR's June 2026 investor presentation, KKR's STT GDC acquisition announcement, BlackRock's GIP acquisition disclosure and GIP's Aligned Data Centers transaction announcement.
Brookfield's investment strategy was assessed using its $100 billion AI infrastructure program announcement and second-quarter 2026 earnings transcript. Macquarie's platform-building record was assessed through its disclosures on the AirTrunk sale and Aligned Data Centers sale.
Additional ownership and financing evidence comes from SoftBank's DigitalBridge acquisition completion announcement, Meta's Hyperion joint venture disclosure, Equinix's atNorth acquisition completion announcement and Equinix's GIC and CPP Investments xScale joint venture announcement.
For broader financing conditions, we examined the Reserve Bank of Australia's research on data center financing and JLL's underlying global data center research report. Together, these sources provide the transaction, financing and industry evidence used to assess which investors have the strongest position today and which have the capacity to expand it.
