Wall Street Turns Data-Center Power into $61B Bonds

Wall Street firms are packaging data-center operations and their power demand into fixed-income securities. Outstanding data-center securitizations increased from roughly $4 billion in 2020 to about $61 billion through July 2026. Investors buy notes backed by real estate, cooling and power systems, fiber routes, leases and tenant payments tied to deliverable megawatts.

Banks and asset managers create special-purpose issuers that hold operating facilities and related contracts. Once a center is open and has paying tenants, owners can transfer the property, equipment and service agreements into a ring-fenced vehicle that issues debt. Cash flows from tenant rent and service fees pay operating costs first-including electricity, maintenance, taxes and insurance-and then repay bondholders.

Credit analysis for these deals centers on tenant payments and the facility’s ability to deliver the contracted power. S&P assigned an A(sf) rating in February to Sabey Data Center Issuer’s $475 million 2026-1 notes. In a July 29 staff response to law firm Latham & Watkins, the SEC’s Office of Structured Finance wrote that securitizations matching the description in that filing may fall outside the Exchange Act definition of an asset-backed security. The staff response is limited to the facts presented and does not change federal antifraud rules or offering requirements.

Market data and forecasts show rapid growth. Research drawing on Barclays data for the Structured Finance Association records about $61 billion of outstanding data-center securitizations by July 2026, up from $4 billion in 2020. The association reports average data-center ABS deals near $600 million and data-center CMBS around $1.2 billion. A Morgan Stanley estimate cited by market participants puts global data-center spending at about $2.9 trillion through 2028. Barclays projects securitizations could reach as high as $180 billion by the end of 2028.

Typical deal mechanics use a master trust or special-purpose issuer that can hold a portfolio of server campuses. Sponsors commonly start with debt no greater than 70% of appraised asset value, leaving at least 30% sponsor equity. Transactions often assume an expected repayment or refinancing around five years while legal final maturities can extend 25 to 30 years, creating potential refinancing risk if market conditions change before notes are repaid.

A data center’s economic value depends on usable power and cooling as much as on land or building size. The Lawrence Berkeley National Laboratory’s 2025 update estimates U.S. data centers could consume about 649 terawatt-hours in 2030 in a reference case, equal to roughly 11.8% of U.S. electricity use, with a range from 521 to 843 TWh depending on chip shipments, server utilization and cooling efficiency. Denser processors can require costly retrofits or utility upgrades.

Tenant concentration is common: a campus can rely on a small number of large cloud and AI customers. If a major tenant departs or renegotiates a contract, cash flow to pay operating costs and debt service can fall. Electricity costs are paid before bondholders receive funds, so higher power prices or constrained deliverable megawatts reduce money available for debt payments. Some operators use flexible compute strategies, throttling noncritical workloads when the grid is strained to lower peak demand and operating costs. The notes give investors a claim on a bundle of property, systems, contracts and an operating business whose cash flow depends on physical power delivery.
