Who Finances Data Centers? REITs, Private Equity, Infrastructure Funds and Debt

A large data center campus is usually financed in layers. At the top is a lease to a tenant whose credit everyone else relies on. Below it sits equity from the owner and its partners, and below that, debt that changes form as the project moves from construction to stabilized operation.⁶⁵ How deals divide ownership between tenants, operators and investors is covered in our guide to how data center deals are structured.

Lenders and rating agencies look first at the lease: its length, the tenant’s credit, who pays operating costs and how power is handled. KBRA has noted that differences in lease form, from triple net to modified gross, widen the range of debt coverage that lenders expect.⁷

The largest source of data center capital is still the hyperscalers themselves. They self-build many campuses, lease others from developers, and back most of the third-party projects through their lease commitments. The scale has outrun their internal cash, however. Reporting on Morgan Stanley’s work in late 2025 said cloud computing companies would spend about $3 trillion on data center infrastructure through 2028, with cash flow able to fund only about half.²

Morgan Stanley’s 2025 research also projected about $200 billion of additional investment-grade technology bond issuance tied to the build-out.¹ JLL’s outlook splits its estimate between about $1.2 trillion of real estate value creation and about $870 billion of new debt, and it notes that most of the construction pipeline is already committed to tenants.³ These are forecasts, not commitments, and they move with each earnings cycle.

Real estate investment trusts own income-producing property and, in exchange for favorable tax treatment, must distribute at least 90% of their taxable income to shareholders each year.⁸ That rule limits how much cash a REIT can retain, so data center REITs fund growth by issuing stock and debt and, increasingly, through joint ventures with private capital.

Digital Realty, one of the two large U.S. data center REITs, describes itself as a leading global provider of data center, colocation and interconnection solutions.⁹ On its April 2026 first-quarter call it reported its largest single lease ever, a 200 MW AI inference deployment with a hyperscaler in Charlotte, and a development pipeline of about 1.2 GW under construction that was roughly 61% preleased.¹⁰

• Strengths: access to public equity and unsecured bond markets, long operating histories and large existing portfolios.
• Constraints: the payout requirement, public-market scrutiny of leverage and development risk, and REIT asset and income tests.⁸
• Typical role: owner and operator of stabilized and preleased capacity, from colocation suites to hyperscale build-to-suits.

Private equity firms buy and build data center platforms, then grow them with fund equity and heavy use of secured debt. Blackstone is the clearest example. It agreed in 2021 to take QTS, then a publicly traded data center REIT, private.¹¹ By its third-quarter 2024 earnings call, Blackstone said its data center holdings were worth about $70 billion, with more than $100 billion of prospective development in the pipeline.⁴ Its agreement to buy AirTrunk for about $16.1 billion in 2024 was its largest investment in the Asia-Pacific region.¹²

Private equity owners tend to hold assets for a defined fund life and then sell, recapitalize or take a platform public. That makes exit options and the resale value of long leases central to how they bid for land and development rights.

Infrastructure investors treat leased data centers like other long-lived, contracted assets such as pipelines or toll roads. The largest recent example is the AI Infrastructure Partnership (AIP), launched in 2024 by BlackRock, its Global Infrastructure Partners unit, MGX and Microsoft; NVIDIA, a technical adviser, and xAI joined in March 2025. AIP set an initial goal of unlocking $30 billion of equity that could mobilize up to $100 billion of investment including debt.¹⁴

On July 21, 2026, AIP, MGX and GIP completed the purchase of 100% of the equity of Aligned Data Centers from funds managed by Macquarie Asset Management, in a deal valued at about $40 billion. At closing, Aligned’s portfolio covered 51 campuses and more than 6.4 GW of operating and planned capacity.¹³

Sovereign wealth funds and pension plans often invest alongside an operator rather than alone. Singapore’s GIC and CPP Investments each took 37.5% of Equinix’s U.S. xScale venture in 2024, with Equinix holding 25%.¹⁵ These investors bring very large, patient pools of money, but they generally want an experienced operator and a contracted tenant before they commit.

Most new campuses are built with borrowed money drawn as construction progresses. Banks remain central: J.P. Morgan provided a $2.3 billion construction loan for the first 206 MW of the Abilene, Texas campus leased to Oracle.⁶ Loans of this kind are sized against the signed lease and repaid, or refinanced, once buildings are complete and rent is flowing.

Private credit has grown into a major lender alongside banks. Morgan Stanley described an opportunity of more than $800 billion for private credit in data center finance, led by asset-based lending.¹ The biggest single deals now blur the line between private credit and the bond market. In Meta’s Hyperion joint venture in Louisiana, part of Blue Owl’s capital was funded by debt sold to PIMCO and other bond investors through a private securities offering.¹⁶

• Bank construction loans: shorter term, floating rate, sized to the lease and the build budget.
• Private credit: flexible structures and larger single checks, usually at higher cost than bank debt.
• Private placements and corporate bonds: long-term fixed-rate debt, at the project or company level.

Lenders’ appetite has limits. Fortune reported in late 2025 that Morgan Stanley was exploring ways to transfer some of the risk on its data center loans to other investors.² For borrowers, the practical effect is that lenders look harder at lease terms, power delivery dates and construction risk.⁷

Once a facility is built and leased, owners often refinance construction debt with securitized bonds backed by the lease payments. KBRA reported that issuers have used asset-backed securities (ABS) since 2018 and single-borrower commercial mortgage-backed securities (CMBS) since 2021, totaling $48.69 billion across 88 U.S. transactions by May 2025, with issuance that year roughly evenly split between the two.⁵

Morgan Stanley projected about $150 billion of data center ABS and CMBS issuance through 2028.¹ Securitization does not fund raw land or early development. It rewards stabilized assets with long leases, which is part of why a developer will pay more for a site whose power and entitlements make a fast lease-up likely.

Every layer of this capital depends on a lease, and every lease depends on a site that can deliver power on schedule. Investors who underwrite data center sites are, in effect, asking whether a lender will later finance the campus. Our guide on site risk for investors and lenders covers the diligence side.

1. 01Identify who is behind a buyer or developer: a REIT, a private equity platform, an infrastructure fund or a hyperscaler.
2. 02Ask whether the buyer needs a signed tenant lease before closing, and how that affects the due diligence period.
3. 03Expect diligence on power, title, environmental condition and entitlements to meet lender standards, not just buyer standards.
4. 04Confirm structure, tax and financing questions with an attorney or financial adviser before committing land to a long-term deal.

The capital is abundant for sites that clear those tests and scarce for sites that do not. If you want an independent read on how a parcel will look to a buyer and its lenders, you can get a site reviewed.
