The debt-financed AI buildout just got its next major test. BlackRock began marketing $12.3 billion in high-grade bonds Friday to fund a massive data center campus in El Paso, Texas, built to power Meta Platforms’ artificial intelligence workloads. The offering is being sold through a single tranche of notes due in 2048, with price talk at approximately 2.875 percentage points over Treasuries. JPMorgan Chase and Morgan Stanley are running the offering.
The financing structure is worth understanding. The project is owned through a holding company tied to BlackRock, with BlackRock subsidiaries Global Infrastructure Management and HPS Investment Partners holding an 80% stake and Meta owning the remaining 20%. Once complete, the facility is expected to provide as much as 1 gigawatt of computing capacity dedicated to AI workloads, enough to power hundreds of thousands of homes if it were serving the grid instead of server racks.
Why This Deal Matters Beyond Its Size
At $12.3 billion, this is one of the largest single data center bond offerings to reach the market this year, and the timing makes it a genuine test of investor appetite. The offering arrives just days after Oracle’s stock fell more than 50% from its June high on concerns about debt-funded AI infrastructure spending and customer concentration risk tied to its own data center buildout. It also follows Alphabet shares falling after the company disclosed a $205 billion spending plan that fueled fresh investor anxiety about the pace and sustainability of AI capital expenditure across the industry.
Against that backdrop, BlackRock’s bond sale is effectively asking bond investors a direct question: is the market still willing to underwrite massive, long-duration AI infrastructure debt at reasonable spreads, or has sentiment shifted enough that these deals now require a real risk premium to get done. A note due in 2048 is a 22-year commitment, and how tightly or loosely it prices will say a great deal about whether fixed income investors share the equity market’s growing skepticism about AI capex, or whether they view infrastructure-backed debt with a hyperscaler tenant as a fundamentally different risk than a company’s own balance sheet leverage.
The Structural Shift Toward Off-Balance-Sheet AI Financing
This deal also reflects a broader trend worth watching. Rather than funding data centers directly on their own balance sheets the way Oracle largely has, companies like Meta are increasingly structuring these projects through joint ventures with infrastructure investors like BlackRock, keeping the debt at arm’s length while still securing the compute capacity they need. That structure spreads the financial risk of the AI buildout across a wider pool of infrastructure capital rather than concentrating it entirely on the tech company’s own credit.
What It Means for Smaller Companies
For investors tracking the broader AI infrastructure ecosystem, this offering is a useful barometer independent of Meta or BlackRock specifically. If a $12.3 billion, investment-grade-rated data center bond prices well, it signals that credit markets still have confidence in the underlying demand for AI compute, which supports continued capital flowing to the smaller companies supplying power infrastructure, cooling systems, and specialized components into projects exactly like this one. If it prices poorly or gets downsized, it would be an early signal that the capital markets are beginning to price AI infrastructure risk more conservatively across the board, a dynamic that would eventually reach every tier of the supply chain, including the smallest companies in it.
