Blue Owl’s Stack seeks a $5.9bn loan, feeding the AI data-centre debt boom

What happened

Blue Owl’s data-centre business, Stack Infrastructure, is aiming to secure a $5.9 billion loan, according to Bloomberg. This financing would rank among the largest single loans in the AI data-centre sector, which is rapidly expanding to meet the escalating demand for AI compute power. Blue Owl has positioned itself as a key player in this space, providing infrastructure that supports AI model training and deployment.

Why it matters

AI development depends heavily on specialized data centres built for heavy-duty processing and massive storage. Stack’s loan request shows how costly and capital-intensive scaling this infrastructure has become. For operators, this means higher borrowing and operating costs are being factored into the AI compute supply chain. Lenders are betting big on AI’s endurance but also increasing the debt exposure of data-centre operators. Businesses relying on AI workloads should expect that infrastructure costs may rise or volatility in financing could pressure prices and capacity availability.

What to watch next

The deal’s outcome will signal how aggressively financiers are betting on AI infrastructure growth amid broader economic uncertainty. Watch for similar large loans or debt issuances from other data-centre firms to see if this raises overall sector leverage. Also monitor how Stack plans to deploy the funds—whether on expanding existing sites, building new centres, or upgrading facilities for the latest AI accelerators. This will reveal which parts of AI infrastructure are prioritized and where bottlenecks might ease or grow.
