AI debt caution spreads to data center CMBS as Pure DC drops planned €1 billion bond sale
Investor caution toward AI-linked borrowing is showing up well beyond the largest funding markets. According to people familiar with the matter, two of the past three commercial mortgage-backed securities deals tied to data center financing had to widen pricing from initial discussions to draw enough demand, including offerings linked to KKR-backed CyrusOne and Blackstone-backed QTS Realty Trust. Over the past 12 months, risk premiums for CMBS tied to data centers have also risen across the board. That shift was underscored in mid-July when Oaktree Capital-backed UK data center operator Pure Data Centres, or Pure DC, abandoned a planned record €1 billion unsecured bond sale and turned instead to bank financing. The company had been marketing the bond while signs were emerging that investor appetite for AI-related data center debt was weakening. At the same time, CoreWeave’s sharp declines in stock and bond prices following news that Meta was building out its own cloud infrastructure made buyers more careful on terms. Pure DC ultimately concluded that the parallel bank loan option offered better conditions. The move reflects a broader repricing. Some investors are starting to treat AI data centers more like traditional office and retail property risk, focusing on overbuilding, tenant concentration and the chance that technological change could erode asset values.
