QTS has launched a $4.6 billion debut investment-grade bond sale, using a green tranche as part of the financing package for a large data centre development in Georgia, underscoring how the artificial intelligence build-out is reshaping both digital infrastructure and the corporate debt market. The company, backed by Blackstone, is seeking long-term funding as demand from hyperscale technology clients accelerates and developers race to secure power, land and capital for new campuses. The bond offering includes a 10-year green note, according to market reporting on Monday, and marks a notable step for QTS as it turns to public debt investors to help finance one of the most capital-intensive segments of the property and infrastructure market. The proceeds are tied to a Microsoft-linked data centre project in Georgia, where QTS has been expanding a vast campus near Fayetteville, south of Atlanta, that has become emblematic of the region’s rise as a data centre hub.
Georgia has become a strategic battleground in the data centre race because it offers large tracts of developable land, access to major fibre routes and a supportive tax structure for qualifying facilities. QTS has been one of the most aggressive builders in the state. Its Fayetteville development, unveiled under the code name Project Excalibur, involves hundreds of acres and plans for millions of square feet of data centre space. Local reporting and industry coverage show the campus has expanded in phases, with filings this year indicating further build-out into the latter part of the decade.
The financing move comes as Wall Street channels ever larger sums into the infrastructure needed for artificial intelligence. Blackstone has identified data centres as one of its highest-conviction themes, and executives have pointed to rapid gains in leasing activity at QTS. On Blackstone’s own account, QTS leasing volume rose by more than 50 per cent year on year in 2025, with growth expected to remain strong in 2026. The private equity group has also highlighted the scale of projected spending by the largest hyperscalers, saying the top five are expected to spend more than $700 billion in 2026.
That growth story helps explain why data centre debt has become one of the liveliest corners of credit markets. Bloomberg reported earlier this year that the AI-led build-out was becoming a major force in debt financing, with banks, private credit funds and bond investors all competing to back new facilities. At the same time, Reuters reported in February that demand for new investment-grade corporate bonds has been unusually strong, with competition in the US primary credit market reaching record levels. For issuers such as QTS, that backdrop offers a chance to raise very large sums from a broad investor base, even as execution risk remains high.
The green label on part of the QTS sale is also significant. QTS has an established Green Finance Framework that allows eligible financing to be linked to energy efficiency and renewable energy projects. A second-party opinion from Sustainalytics said the framework aligned with the Green Bond Principles and Green Loan Principles, and QTS has said proceeds can be directed towards qualifying projects within 36 months of issuance. That structure is likely to appeal to investors who want exposure to digital infrastructure but also want clearer sustainability criteria around power use and efficient design.
Yet the bond sale also highlights the strains building underneath the AI infrastructure boom. S&P Global said last week that planned spending by major technology companies on AI infrastructure could reach $635 billion this year, but warned that higher energy costs and broader geopolitical risks could test those plans. Power availability has become one of the sector’s defining constraints, with developers across the United States facing delays tied to grid connections, transformers and other electrical equipment. For Georgia, as for other fast-growing markets, the question is no longer only whether demand exists, but whether utilities and supply chains can keep pace.
QTS enters this phase with the weight of Blackstone behind it and with a larger strategic profile than when Blackstone agreed to take the former listed REIT private in 2021 in a deal valued at about $10 billion including debt. Since then, QTS has moved from being a specialised data centre operator into a central pillar of Blackstone’s infrastructure and real estate ambitions. Its leadership page says the company has 75 data centres in operation or under development across the United States and Europe, with annual leasing revenue of more than $3 billion and contracted power capacity above 3 gigawatts.
