AI Data Centers Strain Insurers' Capacity and Underwriting

The rapid build-out of AI-optimized data centers—financed increasingly with private equity, private credit and complex debt structures—is creating a capacity squeeze for insurers and lenders. Large private infrastructure deals have repeatedly exceeded $10 billion, putting single-location exposures into the multibillion-dollar range that traditional insurance pools struggle to cover. Brokers and underwriters are responding with bespoke policies, specialized teams and new structuring, but risks span construction, power and water supply, cyber exposures, and potential litigation when financial stress hits. For insurers, the boom is both a revenue opportunity and a systemic stress test that requires new modelling, limits reallocation, and closer coordination with financiers and operators.
